In short

The “401(k) sprints” concept—short, intense periods (typically 5–10 years, or cycles like 2-years-on/2-years-off) where you max 401(k) (or 403(b)/457/TSP) contributions, then pause/reduce while letting the invested money compound for decades.

Key claims

time value of money means early sprints can yield “10–20x” future value per dollar; you may not need lifelong discipline; catch-up and “super catch-up” contributions (Secure Act 2.0) accelerate late starts; traditional vs Roth depends on tax bracket, and Roth has no RMDs.

Notable examples

25–30 five-year sprint (annual $23,500, 8% return, employer match excluded) ends at about $2.038M at 65; 25–35 10-year sprint about $3.988M; 25–35 2-on/2-off about $2.931M. In 40s: 40–45 five-year sprint about $951k; 40–50 10-year sprint about $1.5M. In 60s: 60–65 five-year sprint about $430k.

2:46What's up, everybody? And welcome to the Personal Finance Podcast. I'm your host, Andrew, founder of MasterMoney.co.

3:23Now today, we're going to be diving into what we call 401k sprints. And I'm going to be introducing this new concept that I think is going to be freeing for a lot of you out there because you are going to learn that maybe I don't have to be super disciplined for the rest of my life. Maybe if I get hyper focused for short periods of time, I can then build a tremendous amount of wealth, be on track to retire and do anything I want in my life because you are pursuing financial freedom. That is why we are trying to ensure that we are saving for retirement and getting our money right so that we have either the option to leave a job or we can leave a job that we absolutely hate.

3:59So freedom is the goal. And we're going to talk through some of these 401k sprints. Now, you've most likely never heard of a 401k sprint. And this is a term that we have come up with talking through some of these focused and intentional periods that are for shorter periods of time, usually anywhere from five to 10 years. But I'm going to give you a bunch of options in this episode today, where you go all in on maxing out your retirement contributions, knowing that you won't necessarily be sustainable for long term, but you're going all in for a shorter period of time and trying to save aggressively during that time frame.

4:30Instead of having to save extremely aggressively and trying to max out those accounts for 30 to 40 years, you may have a specific goal and you kind of know where your retirement number is going to be. And so you're willing to pick a window of time where you're going to get ultra disciplined, you and your family are going to buckle down and you're going to start to save in these retirement accounts, max those puppies out. And then from there, let compound interest to do all the heavy lifting for you. Now, the power of compound interest is absolutely amazing. We're going to show you some of the calculations today in this episode on how cool this is.

4:58Now, what this does is it flips traditional retirement ideas on its head, meaning instead of you just saving a small amount over time, which is a tremendous way to save for retirement. But instead of you saving those small amounts every single year over time, you choose these sprint periods and you can have these short bursts of intensity that allow you, if done correctly, to have massive long-term results. Now, here's how this works in practice, okay? You pick your sprint period. Maybe your sprint period is even less than five years. Maybe it's five years, maybe it's seven years, maybe it's 10 years, or maybe you even want to just do a couple of years to get the ball rolling when it comes to getting your financial life right.

5:34Now, during that time, what is going to happen is you're going to contribute the maximum amount allowed into your 401k or similar accounts like your 403b, your 457, your TSP, depending on what your employer sponsored plans are at where you work. Now, once the sprint is over, you could then either pause or reduce your contributions or just stick to the employer match if you wanted to, if it will keep you on target to hit your retirement number. But your invested money continues to compound for decades. So you got these dollars into these retirement accounts, they're going to continuously compound over time.

6:08Now, some people may be saying, well, isn't this just coast fire? No, this is a little bit different than coast fire because you're picking a very short timeframe to do some of these sprints. And then you're going to either decide, do you want to continue investing? And or do you want to take a break for a certain period of time? So maybe you do a couple of years on a couple of years off. We'll talk about those scenarios too. And it'll be more flexible for a lot more people out there. So some people may never have to contribute again. If you get really intense for five, seven, or 10 years, you may be at the point in time where you never have to contribute again.

6:39But if you are out there and you're saying to yourself, well, I just want to do a couple of years at a time, or maybe I want to do one year on, one year off, but I want to get really intense for those one years on, then you can do that for sure. Now, the secret behind these 401k sprints is the time value of money. This is what I want every single person out there to understand. The earlier and the more aggressive you get with these 401k sprints, the more time you have for these contributions to grow exponentially. So every single dollar that you invest in your 20s or 30s can be worth 10 to 20 times more in the future if you get those dollars working right now.

7:13So this is why I want a lot of young people out there listening. If you can figure out ways to do some of these 401k sprints early on in your investing journey, those dollars are going to be so much more valuable than someone who has to start in their 40s or 50s. You have no idea how valuable this is going to be. And you're going to see in these examples today as we go through it, how valuable these dollars truly are. You have the opportunity to absolutely change your financial life just by going after some of these 401k sprints. Now, what are some examples of people who would actually be interested in a 401k sprint?

7:43One is before a major life change. So let's say, for example, you just get married. For example, my wife and I, when we got married, we knew we wanted to have kids later on down the line. During that timeframe, we decided, ooh, we're gonna have some extra income, some disposable income. We're dinks. We have dual income, no kids during that timeframe. so maybe we should try to save as much as we possibly can during this time. And then when kids come along, obviously things are going to get a little more expensive. So major life changes is going to be really, really powerful. Or maybe, you know, in a couple of years, you want to buy a house.

8:12You want to go really hard and make sure you're hitting those retirement accounts before you go out and buy a house. Or maybe, you know, retirement's coming down the road in 10 years and you need to get the ball rolling. You're in your 50s. You want to make sure that you have a great retirement. That's a great reason. Or maybe you feel like you're late to the retirement game. you're in your late 50s, early 60s, and you need to get the ball started. That is another great reason. Or maybe your kids finally left the house. You're in your 40s, maybe your early 50s. These major life changes are happening.

8:39They finally went away to college. They're on their own now. And now you have some extra income and you want to do a 401k sprint as well. There's so many different reasons and major life changes that could be happening. Secondly, is a career peak. Let's say, for example, you got a big raise, you got a big promotion, and you got these extra dollars coming in. You want to make sure that you are taking advantage of all the hard work that you are taking on, meaning you're working hard day in and day out at your day job. You don't want this money to just get wasted away. You're not working hard for no reason.

9:06You're not working hard to buy a depreciating asset like a car that goes down in value every single year. Instead, you want to make sure that you're preserving this so that you can buy your freedom back. If that's you, that's another great reason. Or maybe you're just early on in your career. You want to live lean in your 20s, Or you want to live lean in your 30s and try to get some of these extra dollars working so that you can retire when you want instead of trying to worry about this later on in life. Or you just want to do a balance. We're going to talk about two on and two off sprints. And you want to have a balanced approach to saving, but you also want to live life a little bit.

9:36And so you want to come up with some ideas on how you can do that. It's not about just saving every year, but you can have these short bursts of intense savings that allows you to become financially independent. Now, first, before we talk through the 401k, I want to make sure that everybody understands what a 401k is. This is an employer-sponsored plan that you have through your workplace typically. And or if you're self-employed, you can look at a solo 401k. Or for those out there, there's also Roth 401ks. And so we're going to go through each and every single one of these. So the contribution limits of 2025, which is the time I'm recording this, is$23 ,500 for anybody under the age of 50.

10:11That's what they can contribute to their 401k. Now, if you're between the ages of 50 and 59, you can contribute up to$31 ,000 because this includes something called a catch-up contribution. Now, the catch-up contribution is$7 ,500 this year. And the beautiful thing about these are that they are going up every single year. Now, there is a new catch-up contribution that's called the Super Catch-Up Contribution, thanks to Secure Act 2.0. So people between ages 60 to 63 can contribute$34 ,750. That is something that is pretty new and a great option for folks who are late to the game. Now, these apply across all.

10:51So the traditional 401k, the Roth 401k, a 403b, a 457, a TSP, etc. All of those accounts, this will apply to across the board. Catch-up contributions, by the way, for those of you who can take advantage of those are such a powerful tool because they allow you to get extra dollars into these accounts without having to worry so much. You can accelerate your path to wealth even late in the game. So catch up contributions are another great reason to do a sprint. Let's say you do an early sprint in your 20s and then you do a sprint. Maybe you do a couple of years sprint in your 30s. Then you do another sprint in your 40s.

11:26And then when you hit your 50s, if you have those catch up contributions, getting more dollars in there, man, it's going to be a powerful, powerful tool that you can use. Now, what is the difference between a traditional versus a Roth 401k? This is very important to note for most people because the tax treatment truly, truly matters. And so you need to understand your tax situation. And I highly recommend if you have a CPA, go to your CPA and say, hey, which one is better for my financial situation right now? So a traditional 401k, it means you're contributing with pre-tax contributions. So you get a tax deduction today, meaning your money grows tax-deferred in a traditional 401k, and then it's taxed as ordinary income in retirement when you withdraw those contributions.

12:05Now, the hope is you have a lower income possibly in retirement, and so typically, you may get a favorable tax treatment if that were the case. Now, secondarily, though, is the Roth 401k. Now, the Roth 401k is an amazing account because of tax-free growth. So this is post-tax contributions, meaning your money's already been taxed, and you contribute money to the Roth 401k. But the difference is the money in the Roth 401k grows tax-free and you can pull the money out tax-free. Now, one big caveat with the Roth 401k that is very, very powerful is there are no RMDs in a Roth 401k. No required minimum distributions in this Roth 401k.

12:41Very important to note because in a traditional 401k or a traditional 457 or 403b, all of those are going to have required minimum distributions where you have to pull money from that account. the IRS says, hey, I want you to pay taxes at some point in time on this money. So you're going to be required to pull money out of these accounts. And so you need to understand that. Now, how do you decide between the two? First, number one, always talk to your CPA. If you have a financial advisor in your corner, talk to them and have them look at your tax situation. Very, very important. But some general rules of thumb.

13:12If you expect to be in a lower tax bracket in retirement, a traditional could be a great option. But if you expect to be in a higher or similar tax bracket, a Roth is a great option. Now, here's the powerful thing. We've talked about this a number of times. Let's say, for example, you max out a Roth 401k for 40 years. If you did that at a 10 % rate of return, guess what's going to happen there? You're going to have about$10 million in that Roth 401k because it's incredible what happens when you max these accounts out. But here's the powerful part. About$9 million in that Roth 401k is completely tax-free because they have that tax-free growth.

13:44So you really want to make sure that you're not taking this decision lightly. You've got to look at your situation and decide between the two. And you can also do a hybrid strategy. You can split contributions between both to hedge tax risk if you wanted to go that route too. So a lot of great stuff here as we go through this. Now I'm going to go through the different types of sprints that we're going to be talking about in this episode. And then we will go through examples of those sprints by age, because I love to give you guys examples. I want you to see what it would look like if you're in your 20s and you started to do a sprint, or if you're in your 40s and you started to do a sprint, what is this going to look like and how much would you actually have in retirement based on specific rates of return.

14:21So first, I'm going to explain all the sprints that we're going to go through, and then we're going to talk through this by age. All right, so I'm going to give you a bunch of different sprint strategies. So the first one we're going to be talking through is something called the five-year sprint. Now, a five-year sprint means you are going as hard as you possibly can for five straight years trying to max out contributions in your retirement accounts and trying to just shove as much money as you possibly can in those retirement accounts. Now, there's a number of different things that you can look at here.

14:48Now, for example, if you start at age 25 and you aggressively max out your contributions for five years and then stop by age 65, you'd have$1.5 million. So just for contributing and maxing it out for five years, you'd have 1.5. And another example is if you started at age 30, you'd have 1.4. Another example is if you started at age 40, you'd have$743 ,000. So early sprints equals maximum compounding power. But these five-year sprints are something we're going to look at by age. Then there's the seven-year sprint. So if you're someone who is saying to yourself, nah, that's not enough money. When we reach that point in time where we get to say$1.5 million, I want to have a lot more in retirement than then.

15:24We can look at a seven-year sprint. And we're going to look at this middle ground to see what the difference is. Next is a 10-year sprint. Now, this is one, a lot of people in the financial independence space, who are trying to retire as fast as they possibly can, they will look at these 10-year sprints. And people have become completely financially independent by just really going hard for 10 years. We'll do an entire episode talking through how to become financially independent in 10 years or less, because it's a very important concept that I think a lot of people are looking to do. They want to become financially independent as fast as possible.

15:54What does that look like? And then we're also going to talk about the two on two off cycle. So the two on two off cycle is going to look like this. You go really hard for two years and you max out contributions in your retirement accounts. then you take your foot off the gas. You can either ease off for two years and or reduce your contributions to zero for two years. And then you repeat this over and over again. So this is going to allow you to a max out contributions in certain years where you know, you can go hard. You have some extra dollars on hand. Maybe you just got a raise and you're going to feel it as much.

16:22And so you can get those extra contributions into those accounts. And then some other years, maybe you're taking the foot off the gas. Now, what are some examples of people who would do a two on two off? So maybe, for example, you know, you get a big bonus at the end of every year. And so some years you want to take that bonus and you want to enjoy the money. And then some years you want to take that bonus and you want to make sure you're maxing out your retirement accounts so that you can prioritize freedom. That's a great example. Or when you get a tax return every year, let's say you get a bigger tax return every single year.

16:50When that money comes in, you can decide one of two things. Do I want to max out the rest of these accounts with this tax return? Or do I want to spend this on something that brings me value? Now, when it comes to financial windfalls, the balanced approach to those is to do the 50-50 method, meaning 50 % goes to you and you could spend it on whatever you want. And 50 % goes to future you and you can put it towards retirement, emergency fund, those types of things. That's the balanced approach that I like to take. But for some of you who want to do some sprints, you're going to want to take these financial windfalls and stuff them into as many investment accounts as you possibly can during those sprint periods.

17:22And so for some of you there, a balanced approach of two on two off might be the best ways to go. Now, this is going to emphasize that consistency over time can lead to massive results if you do two on, two off. So these are the different cycles I'm going to talk about. You can creatively come up with 401k sprints that matches what your lifestyle is as well. So think through this. Maybe you want to do six months on, six months off throughout the year, and you want to split the year into two. Maybe you want to do one quarter on, one quarter off, and you want to split the year up so you have enjoyment times and you have buckle down times where your family really buckles down.

17:54All of these can be ways that you can creatively come up with this. And so if you have some new ideas as we go through this by age, I want to hear them. I want to hear what you plan on doing. And if you plan on doing some of these sprints, leave them in the comments on YouTube or Spotify, and or you can send them over to me via email as well. But I want to hear what type of sprints you are considering doing. Now, let's get in to some scenarios of 401k sprints by age. If you've ever felt like your bank is working against you instead of for you, you're not alone. Between overdraft fees, monthly fees, and just trying to access your own money, it all adds up fast.

23:19Every summer, the kids are a little bigger, a little more independent, and life looks a little different than it did the year before. And it reminds me that while we can't predict the future, we can prepare for it. That's one of the reasons I like PolicyGenius. See, PolicyGenius isn't an insurance company. They're an online marketplace that lets you compare life insurance quotes from some of America's top insurers side by side for free. And their licensed team helps you compare coverage, prices, and terms, answers your questions, and even handles the paperwork so you can get the right policy without the hassle.

23:54For me, having life insurance isn't about expecting something to happen.

And with Policy Genius, you can find 20-year life insurance policies starting at just$276 a year for$1 million of coverage. Head to policygenius.com to compare life insurance quotes from top companies and see how much you can save. That's policygenius.com. All right, let's look at these 401k sprints by age. We're going to start off with the 20s. So if you are in your 20s and you're listening right now, I want you to seriously consider this because you have so much time for your money to compound.

24:33You have no idea how valuable each of these dollars are. We have something called the wealth builders matrix. If you go to mastermoney.co slash resources, and what that shows you is every single dollar you invest based on how old you are, what are those dollars going to be worth by the age of 65? It's going to make you rethink going out for drinks with friend and getting that$20 cocktail. Because if you're at the age of 25, every single dollar that you spend can be worth 50, 60 bucks, depending on where you invest those dollars. And so making sure you just have the understanding of opportunity costs and the trade-offs here can be really, really important.

25:06Now let's dive into this. I'm going to give you the assumptions that we have in this episode, and you can run these simulations based on how you want to do this too. So we did the annual return for all of these at 8 % rate of return. I tried to keep a balanced rate of return as we went through this. The annual contribution for 2025 is$23 ,500. That is how much we are putting in for these sprints. The starting balance is$0. So this person, when we go through these scenarios, they have no dollars invested yet. So if you already have some money invested, you're going to be ahead of the curve compared to some of these examples.

25:36Also, the employer match is excluded in these examples. So if you do get an employer match that is excluded, which is also icing on top, there's the stake and the sizzle. And what we're talking through today is we're talking to the stake. All these extra things added on top are the sizzle for you that are going to help you improve your situation as time goes on. Also, the contributions will stop after the sprint period. I want you to note that. So if it's a five year sprint after five years, you stop contributing based on these scenarios to make this as accurate as possible. And then when we go through this, you can think of this in your Roth, or you can think of this through your traditional.

26:12So first, we're gonna do a five-year sprint starting at age 25. So age 25 to age 30, where you do a five-year sprint and your total contributions are gonna be$23 ,500 per year. That's over the course of five years. So you're contributing$117 ,500. So at the age of 65, if you did this, just a five-year sprint, didn't add any more money, just remember all the assumptions, your balance would be$2 ,038 ,000 by the time you retire. That means your growth is gonna be$1.9 million worth of growth over that timeframe. So if you look at the 4 % rule and you withdrew 4%, which is gonna be something we're gonna be challenging in future episodes here.

26:49But when we look at the 4 % rule, that means you could withdraw$81 ,535 per year in retirement if you wanna do this. Doesn't count social security or anything else that you could have. $81 ,535 per year. just for five years of buckling down in your 20s. That is absolutely incredible. That is how powerful compound interest can be for you by putting$117 ,000 in this account. So you get to your first 100K. This is why I tell you as early as possible, get to your first 100K because this is going to change your financial life if you can do it early and often. Now let's look at a seven-year sprint where you go from age 25 to age 31, okay?

27:27So your total contributions during that timeframe is going to be$164 ,500. You're adding two extra years here. Your final balance at 65 is$2 ,766 ,000. So you do this for two years longer. And guess what? You have$766 ,000 more just by buckling down for two more years. And your contributions are going to be about an extra 50 grand right around there roughly. Now your growth is$2 ,601. So if you had this in a Roth 401k, you'd have$2.6 million dollars that you could have grown completely tax-free, hugely powerful. Okay. And with the 4 % rule, it's$110 ,654 is what you could spend every single year, not counting social security, not counting pensions, not counting any other income you have.

28:10If you have rental income or any of that other stuff, that is how much you'd be able to withdraw with 4%. Maybe you want to go 5%. That is coming up on another episode. 10 year sprint. So if you're in your 20s, you want to do a 10-year sprint or age 25 to 35. Let's talk about it. Total contributions, $23 ,500. And so you have contributed in total$235 ,000. Now, the cool thing is, most likely during that 10 years, the IRS is going to increase those contribution limits because they start to increase those limits when inflation happens and a lot of other different factors. And so that is something where you actually will probably even have more in there as time goes on.

28:46Your final balance at age 65 would be$3.988 million, over$1.2 million more than the seven year sprint because you got started from age 25 to 35. So let's just say, for example, that you decide, I'm going to do this. I'm 25 now. I'm going to do everything in my power to make sure I can earn $23 ,500 extra in order to put in these accounts for 10 years, because I want to make sure that I have almost$4 million in this account by the time I retire. Really, really powerful stuff. Why is this powerful? Because if you get this started early, this is not contributing another dollar later on. You could coast the rest of the way if you want to.

29:20This is why Coast Fire and that movement is so powerful. But this is gonna give you more flexibility. Now, the growth on that is$3 ,753 ,000. So again, in a Roth 401k, that would be the growth completely tax-free. Really cool stuff. And then with the 4 % rule, you can withdraw$159 ,555. Now let's go one more in the 20s, which is the two-on, two-off strategy, okay? So two on, two off, meaning you're contributing for two years, you skip two, and you repeat five times for 10 years total. Contributions are over 20 years, okay? So you're going to do this 10 years of contributing money to your Roth 401k and 10 years not contributing money.

29:58So that means your total contributions are going to be$235 ,000. And your final balance, because you're two on, two off, is$2.931 million. So look at the difference there. A 10-year sprint where you don't do two on, two off, you're going to be contributing the same amount of money,$235 ,000 into this account. But if you did the 10-year sprint earlier, you would have$3.988 million. But if you did two on, two off, you would only have $2.9 million, which is still a great outcome, but it's a million dollar difference if you did the sprint early on and got your money invested early and often. Very important to note because getting dollars invested early is just one of the most powerful things.

30:39This is why we talk about this. Time is your greatest ally when it comes to investing. Now, even if you don't have a lot of time, we're going to talk about that in a second here. If you're in your 40s, if you're in your 50s, getting those investment accounts maxed out is still really powerful. And we're going to show you here next. So let's jump into the 30s next. All right. So if you're in your 30s, then we have something that we are looking at here for this scenario. We're going to assume the same exact stuff, okay? So we're going to assume 8 % compounded annually in your 30s. We're going to assume the annual contributions are$23 ,500.

31:11Now we're also going to look at the median investable assets for someone age 30 from the Federal Reserve data. And we're going to look at this and say, okay, well, the median investable assets for someone in their mid thirties is$37 ,000 according to the Federal Reserve. So we're going to assume you have$37 ,000 to make this realistic. Employer match in your thirties is going to be excluded and contribution stop after your sprint period again. So same exact thing as last time, except we're going to assume that you have a starting balance somewhat in your 401k. And a lot of you out there who are in your 30s, you started investing.

31:44If you haven't started investing yet, that's completely okay. We'll get started now. Now for a five-year sprint for someone, again, we know how much we're contributing$117 ,500. If you started between age 30 to 35, your final balance would be$1 ,786 ,000. So let's think about this for a second. Okay. So this person started five years later than the person who started at age 25. And starting five years later actually is going to cost them about$300 ,000, which is a big, big difference in that growth because at least they still got that sprint early and often, but they already had$37 ,000 invested.

32:20And so because they had a little bit invested, this grew still a$300 ,000 difference. It'd be a much larger difference if you had a$0 balance. Now, the seven-year sprint is going to be something where we're going to contribute$164 ,500 in your 30s, okay? And your final balance is going to be$2.281 million, meaning with the 4 % rule, you can withdraw$91 ,263 ,000. So if you're someone in your 30s and you're saying to yourself, okay, I'm getting started at age 30. I feel like I'm behind, but you're not really. When you're in your 30s, you have so much time left. So many people in their 30s come to me and say, I didn't start yet.

32:56What do I do? And they start to panic. You are not behind. You are going to be okay. And you have so much time for your money to compound that you should not worry. It is never too late to get started investing. I don't care if you're 40s. I don't care if you're in your 50s. You can still right the ship. And so that's what this episode is trying to show you is you can right the ship. You just got to buckle down a little bit. And that's okay if you have to buckle down a little bit. Sometimes we have to make sacrifices. But discipline, when it comes to your finances, the way I define discipline is that you are putting your future self ahead of your current self.

33:26And so if you can do that just for a couple of years, it can make a massive difference. Now, when you're in your 30s, I know you're in the messy middle. You maybe are getting married. You maybe are having kids. Maybe you have multiple kids in daycare and it gets harder and harder as time goes on. That's OK. If we can find some years where we can hit some sprints, it's going to massively change your retirement plan over the course of the long run. Now, let's say you took your entire 30s and you decided I'm going to sprint my entire 30s from age 30 all the way down to 39, 40. Okay. So your total contributions there would be$235 ,000 and your final balance at age 65 would be$3 million, meaning you could withdraw$122 ,291 ,000.

34:07And the growth of your money is still$2.8 million. So your money made you$2.8 million without you having to go in and work every single day. Really powerful stuff. Your money can work way harder than you ever can. And so I want you to remember that and get those dollars working. If you did that over the course of 20 years, you have$2.32 million and you'll be able to withdraw$92 ,000. So folks in your 30s, I want you to look at some of these takeaways here. Even with just five years of intense saving in your 30s, you can still hit nearly$1.8 million. That's number one takeaway I want you to think about.

34:40Number two, a 10-year sprint pushes you to$3 million despite starting with only$37 ,000. Really powerful stuff because for 10 years, you buckle down, you have$37 ,000 in that account, You buckle down, boom, get to that point in time where you're making big progress and all of a sudden it changes your life. Two on and two off still nets you$2.3 million, proving that flexibility doesn't kill your retirement plan if you wanna have a little more flexibility. But one thing to note is the later you start, the more you need to contribute in order to hit the same retirement goal for someone in their 20s when they started earlier than you.

35:12They don't have to work as hard as you do in your 30s, but that's okay. Because in your 30s, you're likely gonna be earning more money. You're gonna have the ability to get these dollars working and investing. Next, we're going to talk about the 40s. All right, in your 40s, here are some of the assumptions that we are going to look at. 8 % return again, annual contribution is going to be maxing out at$23 ,500. The starting balance is going to be what the Federal Reserve data shows is the median investable assets for people age 40 and above, which is$58 ,000 is what you're going to be starting with in your account.

35:42And then the employer match is excluded and contribution stop after this sprint period, meaning you're not going to contribute anything else. So just remember this as we go through all these scenarios. If you continue to contribute, these numbers are gonna be much higher. But these are for these sprint periods and these shorter gaps that show you. Now in your 40s, you got a lot of things you got to deal with. You got kids who are getting older. Maybe you got to do a lot of youth sports. Your kids are going to college. You're having a lot of life changes. You have aging parents you have to take care of.

36:08And so there's a lot of things that you are dealing with during this decade, but that is okay. Because if you could find these sprint periods, if you got started late, it's okay because you're still gonna make a tremendous amount of wealth. Watch this. So if you started from age 40 to 45 and you put$23 ,500 per year, that's$117 ,000. Your final balance at age 65, this is the first one coming in under a million, is$951 ,567. So with the 4 % rule, you can withdraw$38 ,062. So if you have Social Security, you have some other income coming in, that's a great starting point is that you at least buckle down for five years and boom, you were able to produce a million dollars in retirement that you can utilize for almost$40 ,000 per year.

36:48Now, this is at an 8 % rate of return. The market returns 10%. These numbers are going to be drastically higher. If it returns less, they're going to be lower. But just making sure that we note that, hey, the S &P 500 over the course of the last 30 years has returned close to 10 % to investors, but we always want to be conservative when we are planning for retirement. Now, seven-year sprint from age 40 to 46, your total contributions would be$164 ,500. And the total amount of money that you would have. Your final balance would be$1 ,184 ,000, meaning you could withdraw$47 ,394 if you did a seven-year sprint.

37:22That, my friends, is a much better number, I think, than a five-year sprint. So if you're in your 40s and you want to have a better retirement, I would sprint longer if you could. Because since you're starting late, you just got to work a little harder and you got to contribute more money for longer periods of time. Honestly, if you're going to do this, I would also continue to contribute after this. But the sprint is just to get you started to get that bulk going. Now for a 10 year sprint, you would contribute again, $235 ,000. And your final balance at age 65 would be$1.5 million, meaning you could withdraw$62 ,183 per year with the 4 % rule.

37:55And the growth of your money is going to be$1.3 million. So still a tremendous amount of money for starting in your forties. And because of this, it can be very, very powerful. Now think about this. You're going to get to age 50. And all of a sudden, if you decide you want to continue to sprint, you have catch-up contributions in your corner, meaning you can contribute even more money in these accounts than you could in your 40s. And so that's going to allow you to even pick up the pace if you wanted to get to a$3, $5,$7 million retirement. There are extra things that you can do. And then two on and two off, if you did that, your final balance would be$1 ,313 ,000, and the growth would be about a million bucks.

38:28And your withdrawal would be$52 ,522 a year that you can withdraw in retirement as your income. So some key takeaways for your 40s. A five-year sprint can still get you to 1 million bucks. That is really, really cool and a really powerful lesson for a lot of people. It is never too late to get started. A 10-year sprint can get you close to$1.5 million, a huge chunk of retirement funding, even with a shorter compounding runway. So even though your compounding runway is shorter, you can still get to 1.5 million with a 10-year sprint. Two on and two off still builds$1.3 million. So let's say you realize, oh, I need to get started on retirement.

39:01Well, over the course of the next 20 years, two on, two off will still get you to 1.3 million. And the time is shorter. So the contributions are going to matter more in your 40s than for somebody in their 20s. It's going to matter a lot more for you now. And so getting more in is really, really important and buckling down. So next, we're going to jump into the 50s. So in your 50s, a lot of things are going to happen in life. A lot of life changes are going to happen. A lot of shifts will happen. You're going to really start to think about retirement. And so you want to make sure that you are taking advantage of these catch-up contributions.

39:31So in this scenario, we ran it at an 8 % rate of return again. Your annual contribution is going to go up. We want to give you that catch-up contribution to$31 ,000, which is the catch-up contribution for 2025 is$7 ,500. And so the starting balance, we looked at the Federal Reserve's median balance for people in their 50s, which is$95 ,000. And so that's what your starting balance is going to be in these calculations. And then obviously contributions stop after the sprint period, and employer match is excluded in this as well. So for a five-year sprint, for someone who sprints for five years from age 50 to 55, your total contributions are going to be$155 ,000.

40:08And your final balance at age 65 would be$492 ,201. And the growth of your money would be$242 ,000. And you could withdraw$19 ,688. So I would highly recommend for those who start in their 50s, if you're starting late, do these sprints for longer. Do them as long as you possibly can so you can get to the point in time where you have a tremendous retirement. Now, if you did it for seven years, your final balance would be$603 ,000. And the growth of your money would be$386 ,000. And the 4 % withdrawal rule, you could withdraw$24 ,161 in that scenario. Now with a 10-year sprint, you would have$771 ,000 and you could withdraw$30 ,000 per year if you did it from age 50 to 60.

40:50And so this is one where if you're starting late, I would highly recommend that you do that. Now, some of you may have more contributed on that account already. It's going to make a big difference if you do, because this is start with$58 ,000. If you have a hundred grand or maybe a couple hundred grand inside of your 401k already, then this is going to make a big, big difference to what these numbers actually are. And then two on and two off. So compounding stops at 65 so that all the cycles will complete, but two on, two off would have a final balance of$677 ,000. And the 4 % rule would be$27 ,100 is what you could draw on that money.

41:21So some key takeaways is even with five years of maxing out, you can almost have$500 ,000 added to your nest egg for retirement. That can make a big difference for a lot of people out there. A 10-year sprint gets you close to$800 ,000. Huge difference for a lot of people out there. And even the two on and two off gets you to$680 ,000 during this scenario. Proof that intensity and time still works in your favor, even if you don't have as much time as you would like. And so this is where I want most people to realize it is never too late to get started. If you're listening to this and your parents haven't caught up, for example, then send this to your parents so they understand that they could still get the ball rolling.

41:57Now, we're also going to do scenarios for the 60s because people need to note that this is going to be something that you could do. So let's look at the 60s. We're going to do the same rate of return, 8%. The annual contribution is going to be the super catch-up contribution. So$34 ,750 is what you can contribute. And the starting balance, the medium investable assets for people in their 60s is$145 ,000. Man, that's tough to hear because it's not enough to retire on. And so we're trying to change that right now for all of you and making sure that you get a higher number there. Employer matches excluded on this one too.

42:27And the contribution stop after the sprint. So a five-year sprint from age 60 to 65, meaning that what would happen here? So your total contributions, because you could do$34 ,750 would be$430 ,000 and one year of$31 ,000, meaning it's or 60 is when you can start to have that super catch-up contribution. So we're looking at$170 ,000 invested. The final balance at age 65 would be$430 ,410. Wow. I mean, I think that is incredible. And that is something where you can still withdraw$17 ,216. So with a seven-year sprint, the final balance would be$505 ,000, and you could have$20 ,000 per year in additional income.

43:05And a 10-year sprint would be$586 ,000, and you could withdraw$23 ,457 per year. Plus, on the two year two off, which I wouldn't recommend in your 60s, this would be from age 60 to 80. And so really, for most people, this isn't going to work for them. But we did the scenario anyway, your 4 % withdrawal rule would be$19 ,200 per year is what you could have and your final balance would be$480 ,000. So there's no reason if you're in your 60s and getting started, there's no reason to do two on two off, you need to buckle down and get the ball rolling. So some key takeaways for the 60s, even with just five years to save, you can still add nearly$430 ,000 translating to$17 ,000 per year in retirement.

43:44A 10-year sprint gets you close to$600 ,000 or about$23 ,000 a year in income. And the two-on-two-off still can get you$20 ,000 per year, but you got to do it till you're 80, which is tough. So the super catch-up contributions under Secure Act 2.0 are incredibly powerful for people in their 60s. So some final takeaways from this episode that I want everybody to understand as we start to wrap this up is that your 20s and 30s, compounding does the heavy lifting. 40s and 50s, your contributions are going to do a lot of the heavy lifting. And in your 60s, catch-ups and time to income do a lot of the heavy lifting.

44:18And so for most of you out there, the earlier you can get started, no matter how old you are, starting today is one of the most powerful things.

In this episode of The Personal Finance Podcast, Andrew introduces the 401k Sprint strategy—a game-changing approach where you max out retirement contributions for just 5-10 years instead of grinding for 30-40 years straight, proving that a 25-year-old who contributes $23,500 annually for only 5 years can retire with over $2 million while someone starting at 60 can still add $430,000 in just 5 years using catch-up contributions. He breaks down the exact numbers for sprints starting in your 20s, 30s, 40s, 50s, and 60s, explains the difference between traditional and Roth 401k strategies, and shows why the 2-on/2-off cycle approach (maxing contributions for 2 years, taking 2 years off, and repeating) can still build nearly $3 million by retirement—proving that short bursts of intense saving combined with compound growth can beat decades of mediocre contributions.
