Episode Overview

This episode addresses a common investing question: Should you fully fund your Roth IRA as a lump sum early in the year (using, for example, an annual bonus), or is it better to contribute gradually over time? Through a listener's question, Dave Ramsey and Ryan break down the math, habits, and psychology behind both methods, offering actionable advice on how best to build long-term wealth through disciplined investing.

Key Discussion Points & Insights

1. The Listener's Question: Lump Sum vs. Spread-Out Contributions

• Listener Situation (00:21):
  • Ryan and his wife are about to finish Baby Step 3 (emergency fund savings) and anticipate a $15,000 annual bonus in March.
  • Their dilemma: Should they fully fund Roth IRAs with the bonus in one go, or stretch contributions over the year?

2. Mathematical Difference: Is Timing Critical?

• Dave Ramsey's Analysis (00:45):

  • "The difference mathematically is what you might earn if you do the 15 all in a lump sum in March. What would you have earned in March versus 1/12 of the month all the way around? [...] It might be $1,000 difference. It might be $800 difference on a 10 or 12% year."
  • Key takeaway: There’s a small but real gain from investing sooner, since your money has more time in the market.

• Ryan (01:16):

  • "Unless we had a crystal ball, we won't know for sure what the math is on that. But in general, the sooner you get money into the market, the better off you're going to be long term."

3. The Real-World Impact Is Modest

• Dave Ramsey (01:24, 01:44):
  • "Right, but it's not like you're going to have millions of dollars more because you did 15 lump sum versus 1/12th of the time."
  • Dave shares his own approach: front-loading his 401(k), because he owns his company and can. He illustrates how money working longer produces more, but the benefits are incremental, not overwhelming.

4. Consistency and Discipline Matter Most

• Dave Ramsey on Habit (02:44):
  • "The second thing to enter into the conversation, because it's a good question, is you want to be sure if the steady monthly thing keeps you doing it because you're on autopilot versus jumping on and off the wagon with lump sums... you'd be better off sticking with the one that keeps you doing it."
  • He reveals his own systems for “tricking” himself into discipline, like automatic drafts for investments and bills:
    • "I set up stuff early in my life... to trick myself into having discipline, like automatic 401ks or automatic draft on my checking account for Roth IRAs..." (02:54)
    • Shares the evolution from mailing checks to employing auto-draft for everything to ensure consistency.

5. The Power of Living Below Your Means

• Ryan (03:51):
  • "If you're investing 15% of your income forever, you're gonna learn to live on 15% less than you would have. And so it's sort of like that money was never there. And that's a good way to live because it keeps you in check."
  • Emphasis on how automatic, consistent investment changes your mindset and spending habits.

6. Making Investing a Habit—Whatever It Takes

• Dave's Final Advice (04:09):
  • "Whatever you do, trick yourself into being consistent. And when given the opportunity, a lump sum early in the year will outperform a steady monthly investment because it's been in there longer."

7. Dollar Cost Averaging Clarification

• Ryan (04:36):
  • "There's a fancy name for that, dollar cost averaging."
  • Dave Ramsey (04:38):
    • "Well, that's what you're not doing is dollar cost averaging when you put it all in there."
  • Clarifies that monthly contributions = dollar cost averaging; lump sum is the opposite.

Key Takeaways

• **Lump sum funding of your IRA at the start of the year will mathematically outperform monthly contributions, but usually by a modest amount.
• Discipline and consistency are far more important than the precise timing of contributions. Do what ensures you stick to your investing plan.
• Setting up investments on autopilot—so contributions happen automatically—greatly increases your long-term success.
• Living on less and investing regularly teaches habits that drive accumulation of wealth, not just growth of investments.
• Understand what "dollar cost averaging" means, and that doing a lump sum means you aren't dollar-cost averaging, but that's okay if you can manage the discipline.

[Dave Ramsey]

Hey, Ryan. How are you?

[Ryan]

I'm good.

[Caller]

How are you?

[Dave Ramsey]

Better than I deserve. What's up?

[Caller]

Thank you for taking my call.

[Dave Ramsey]

Sure.

[Caller]

My wife and I are currently in baby step three and we'll be finished with that by the end of the year. We receive an annual bonus in March. It'll be roughly $15,000 take home. Would it be better for us to take that 15 to fully fund our Roth IRA or to spread our contributions out throughout the year and use the bonus between steps 4, 5 and 6?

[Dave Ramsey]

It doesn't matter much. Either one will be fine. The difference mathematically is what you might earn if you do the 15 all in a lump sum in March. What would you have earned in March versus 1/12 of the month all the way around? And so, you know, like say the average might be what you would earn on 8 or 10,000 of that 15. So it might be $1,000 difference. It might be $800 difference on a 10 or 12% year.

[Ryan]

Unless we had a crystal ball, we won't know for sure what the math is on that. But in general, the sooner you get money into the market, the better off you're going to be long term.

[Dave Ramsey]

Right, but, but, but it's not, I mean, the difference, it's not like you're going to have millions of dollars more because you did 15 lump sum versus 151 12th of the time, all the way around the horn. Right, right. But, but basically, for instance, in my case, okay, I fully fund my 401k for the whole year in January, okay. I dump the whole thing in there, okay? Because I can, I own the company and I can just bonus myself whatever I need to and make sure I got enough to do that, right? So I just load the stinking thing up and then I've got that, I don't know, let's call it 20,000 bucks or 30,000 bucks or whatever it is. It's working the entire year rather than 1/12 working the entire year, 2:12 working part of the year, 3/12 working part of the year, 4/12 working part of the year, and so on. You follow me? So the difference is what I would make on 30 grand, 27 grand, 28 grand, 24 grand, 23 grand, 22 and so on all the way around the horn. And so it's. George is right, a lump sum up on the front end is gonna average More than doing it monthly. The second thing to enter into the conversation, because it's a good question, is you want to be sure if the steady monthly thing keeps you doing it because you're on autopilot versus jumping on and off the wagon with lump sums and you're not as predictable with it, sustainable with it. That way you'd be better off sticking with the one that keeps you doing it. And so I set up stuff early in my life once I started understanding these principles to trick myself into having discipline, like automatic 401ks or automatic draft on my checking account for Roth IRAs or those kinds of things back in the old days. So I automatically had debt. I went so far as I. In the old days when I started this stuff, there was no Internet, of course, and so there was no auto. There was very little auto draft on utilities and that kind of stuff. Used to have to write a check and send your electric bill through the mail. Okay. And as soon as they set it up where they would take auto draft, I put all my utilities on auto draft so that I never missed a discount. And that's been, God, that's 25 or 30 years I've been doing that. So anything I can do to have autopilot. Automatic discipline.

[Ryan]

Yeah, I like that mentality because if you're investing 15% of your income forever, you're gonna learn to live on 15% less than you would have. And so it's sort of like that money was never there. And that's a good way to live because it keeps you in check. So I think that long term discipline is key. But for this year, if you just wanted to fund them and be done with them and move on.

[Dave Ramsey]

That's correct. If you, you know, if for 10 years you've always gotten a bonus in March of 15 grand and you want to just label that, that's gonna go towards our retirement and we're gonna do less through the rest of the year. Fine. I don't know. But whatever you do, trick yourself into being consistent. And when given the opportunity, a lump sum early in the year will outperform a steady monthly investment because it's been in there longer.

[Ryan]

There's a fancy name for that, dollar cost averaging.

[Dave Ramsey]

Well, that's what you're not doing is dollar cost averaging when you put it all in there. Yeah, you're missing out on that.
