White coat investors know that I like to make fun of all of the retirement researchers who come up with literally hundreds of withdrawal rules that show you how best to spend your retirement nest egg to ensure you don’t run out of money before you run out of time. For those for whom it matters (which is not all that many white coat investors because there are so many oversavers among us), I prefer a much less formal plan I call “start at around 4% and adjust as you go.”
If you have no idea what I’m talking about in the above paragraph, why don’t you start by reading these posts?
How to Know If You Need to Adjust
There are two questions a retiree needs to address each year or so as they go throughout retirement, spending their money. The first is whether an adjustment is necessary. This is where the real strength of the part of my recommendation to “start at about 4%” comes in. You see, the historical data, limited as it may be, shows that you can withdraw 4% of the initial nest egg each year, adjusted upward for inflation, and expect to have a very low likelihood of running out of money in a 30-year retirement. Most people aren’t even retired for 30 years because they die sooner than that, but that’s how the studies were set up. So, if you start at about 4% (and if you want to be conservative, you can drop that to 3.75% or a very conservative 3.5%, which is not unreasonable if you’re retiring in your 40s or 50s), almost all of your adjustments will be upward, not downward!
This is very similar to the “ratcheting” type withdrawal plans, where you increase withdrawals/spending as the portfolio grows in retirement. If you find your portfolio is 25%, 50%, or 100% bigger than what you retired with, that should be a sign that you can safely increase spending without worry about running out of money. If nothing else, just imagine you were retiring today instead of a year ago or four years ago. Is 4% of the current portfolio more than 4% of your original portfolio adjusted for inflation? Then, go ahead and use the new 4% as your number.
If you’ve decided to roll the dice a bit and spend 5%, 5.5%, or 6%, you have to keep a much closer eye on this process. Remember, if the sequence of returns risk—SORR (the risk that you run out of money despite having adequate average returns because the crummy return years show up earlier in your retirement)—appears, you have to be very flexible with your withdrawals, cutting them by 25% or even 50%. Instead of 5.5%, maybe you’re now withdrawing 2.75%—and you may have to do that for five or even 10 years during the highest spending period of your retirement if there aren’t a few great return years rescuing your portfolio.
However, for the typical person spending something closer to 4%, I would simply run the numbers once a year and see how it’s going. I would compare what my spending looks like to a few of the more formal retirement withdrawal plans to see how it looks.
Is your portfolio larger or smaller than the initial portfolio at the time of retirement? Does 4% of the initial portfolio value plus inflation still cover your desired level of spending? What percentage of the current portfolio will you be withdrawing this year? Does that number seem really high (like >8%) even though you still anticipate decades in retirement?
How does your planned withdrawal this year compare to what you took out in previous years? Less? About the same? A little more? A lot more?
How much could you withdraw this year if you were following an RMD plan? RMDs are:
- Age 75: 4.1%
- Age 80: 5.0%
- Age 85: 6.3%
- Age 90: 8.2%
- Age 95: 11.2%
Some even advocate that you can multiply those numbers by 1.5 and still be fine, which would give you a table that looks like this:
- Age 75: 6.1%
- Age 80: 7.4%
- Age 85: 9.4%
- Age 90: 12.3%
- Age 95: 16.9%
If you’re 80 years old and you’re withdrawing 4.5% of the current portfolio value, you can surely withdraw and spend more. If you’re in the 5%-7% range, you’re doing fine and probably on track. If you spent 9% or 14% last year, there’s a real issue—running out of money should be a serious concern for you, and it’s time to dial back. Way back.
There are lots of other rules with which you can compare your spending. Pick two or three of them, project your spending rate against each of them each year, and make sure it never looks like what you’re doing is nuts. If your spending level is failing all of the suggested spending plans, that should be a sign to you.

Another Tip for the Underspenders
One other thing to consider for the underspenders is that you can go back and take the withdrawals you didn’t take out in the last few years. Let’s say you retired at 65 with a million bucks and figured you could spend $40,000 a year. For the first four years of retirement, you’ve just been living on your pension and Social Security, but this year, you want to do a home renovation. How much can you afford? Assuming no growth at all, there’s $160,000 in the portfolio that you could have taken out in past years, plus this year’s $40,000. So, unless the last four years have been the equivalent of 2000-2002 or 2008 or 2022, you should feel pretty comfortable taking out a couple hundred thousand dollars and spending it.
How to Adjust
If the first question is whether an adjustment is necessary, the second question is, how do you adjust? If you want formal instructions for either of these, I would suggest that you adopt one of the hundreds of withdrawal rules out there. If you’re comfortable eyeballing it, then the adjustment is basically that you spend more when times are good and less when times are bad. The better the times are, the more you can spend. The worse the times are, the less you can spend.
But if your comparison to the 4% rule or the RMD rule shows you haven’t been spending more than those rules allow, you can rest assured that, unless the future is even worse than anything seen in the past, you don’t have to cut back at all. As a maximum cut, dialing back to 4% of the current portfolio value seems more than enough. You don’t have to cut all the way back to just the income from a typical stock-and-bond portfolio, but if you’re really worried, you could do that. That’s probably the equivalent of cutting back to a rate of 2%-3% of the current portfolio.
How much can you adjust upward if times are good? If you have been spending $100,000 a year and you’re now 85 and have a $3.5 million portfolio, you could safely increase that to at least 4% of current value ($140,000) and probably to 6%-9% of current value ($210,000-$315,000). You probably should have increased spending a year or three ago.
Those are the sorts of adjustments I’m talking about when I say “adjust as you go.” You need to know yourself. If you’re a natural cheapskate and saver like I am, you probably need to push yourself to spend a little more on things that would actually make you happier. If you know that controlling spending has always been tough for you, you’ll need to be a little bit more careful.
What do you think? Do you plan to follow a formal withdrawal plan or adjust as you go? Which is your favorite plan? If you are retired, how have you adjusted your spending as time goes on?
