The 4% Rule for Retirement: Will You Have Enough to Retire?

posted on

By Justin Pritchard, CFP®

How can you (hopefully) get the retirement you want while avoiding unpleasant surprises? By making a plan and checking your progress. Planning for retirement requires predicting the future, and you can never do that perfectly. But there are ways to figure out if you’re more or less on track.

Rules of thumb are never perfect, and it’s best to run detailed numbers based on your specific goals and resources. Still, it’s helpful to do occasional “back of the napkin” checkups on your retirement goals. However, as you approach retirement—when it’s within 20 years or so—the need for more precise calculations increases.

The 4% Rule for Retirement Explained

The 4% Rule helps you figure out two crucial pieces of your retirement plan:

  1. Saving need: If you’re still in your earning and saving years, you can figure out how much you need to save to retire comfortably.
  2. Potential retirement income: If you’re getting ready to retire, the 4% Rule helps you estimate how much you can “safely” spend from your savings each year (and safely is in quotes because there are no guarantees in life).

As a result, the Rule is useful for both retirees and pre-retirees.

With the 4% Rule, you can withdraw an annual income out of your retirement savings that’s 4% of your total assets. That withdrawal rate “should” prevent you from running out of money and provide an income that rises each year (so you can hopefully keep up with inflation). The assumption is that you’re planning for 30 years of retirement. However, it is possible to run out of money under a variety of scenarios.

Example: The number 100 is easy to work with. Assume the following:

  • You have $100,000 saved at retirement.
  • You could take $4,000 per year of income for each $100,000 you have (that’s 4% of $100,000).
  • If you have $500,000 saved for retirement, that’s $20,000 of annual income from your investments.
  • If you have $1 million, that’s $40,000 per year.

That may not sound like much, but it might make more sense when we look closer. Plus, you may appreciate hearing that Bengen revised the rule to say that you can potentially withdraw 4.5% in the worst-case-scenarios he tested. But the term “4.5% rule” hasn’t really caught on.

Increasing income: Perhaps most importantly, the 4% Rule is designed to provide an increasing income during retirement. In other words, it’s an income that adjusts—at least somewhat—with inflation. So:

  • Assume you start with $40,000 of income in the first year.
  • The following year, you should be able to withdraw more—maybe $40,800 if we assume 2% inflation that year.
  • Each year afterward, you might be able to increase your withdrawals with inflation.

Remember that this amount is just what you spend from your investments. If you receive Social Security benefits, pension income, or other sources of income, that goes on top of the 4% withdrawal amount.

Does the 4% Rule Make Sense?

So, does it work? It depends. The research originally came out in 1994 based on the work of William Bengen, and it’s been fairly well-established since then, although there’s some debate about the perfect number and the perfect strategy.

Potential drawbacks: People criticize the Rule with a variety of arguments, but it’s a decent starting point to understand if you’re on track.

  • Some say that you should withdraw less than 4% or you’ll run out of money.
  • Some say you can withdraw more, and 4% is too conservative (requiring you to work longer than necessary or make sacrifices during your saving years).

Ultimately, the outcome depends on several factors, like:

  • How you invest: Do you invest in an aggressive or conservative mix of investments?
  • How much “certainty” and comfort you want: There is no certainty in this life, unfortunately, but a lower withdrawal rate is safer than a high one.
  • How willing you are to adjust your spending: Can you be flexible, reducing spending when markets crash?
  • When you retire: What do markets do in the subsequent years? Poor returns or market crashes shortly after you retire can create a “sequence of returns” problem.

You might get away with taking more when the markets work in your favor. In this image, you see how likely you are to run out of money with various withdrawal rates. If you find 4% (on the left), you see that it was successful—you didn’t run out of money in a 30-year retirement—roughly 85% of the time. But as you try to withdraw more, it’s only successful if you increase your risk (holding higher levels of stock), and only if that risk pays off, which not guaranteed.

A lower withdrawal rate also works. But to provide enough income for yourself, you need to save significantly more.

So, What Should You Do?

Realistically, a rule of thumb can answer some basic questions, but it’s insufficient for robust financial planning. But if you want to lean heavily on the 4% Rule, it’s critical to understand the pros and cons—and to be flexible. If you rely on a flat 4% through good times and bad, things might or might not work out, but you’re taking a risk by employing a rigid approach to retirement planning.

Instead, use the 4% Rule to double-check any other planning you’ve done.

  1. If your plan requires you to withdraw more than 4%, do you have a reason for doing so, and have you evaluated the risks?
  2. If your plan uses less than 4%, are you spending less than you could, and are you doing that intentionally?

There’s no right or wrong answer, and you ultimately get to choose how much you’ll spend. It’s your life to live, and you undoubtedly have your reasons for making any decision. For example, if you’re spending significantly less than 4%, maybe the goal is to leave assets to your heirs, and that’s great. The most important thing is to verify that you’re spending with a plan.
