Twelve minus four equals eight. That’s the whole argument. So what is Dave Ramsey’s 8 rule? It’s his claim that retirees can withdraw 8 percent of their savings each year, because stocks return about 12 percent and inflation takes about 4. It sounds neat. Most planners reject it, and the research behind their view is solid. In this article I’ll show Ramsey’s math, the dollar amounts it produces and the benchmarks experts use instead. I’ll also say where his side has a point. I’m not a financial adviser and I haven’t retired, so this is a reading of public sources, not advice. If you’re near retirement, run your own numbers or talk to a fiduciary.
What Is Dave Ramsey’s 8 Rule and Where Does It Come From?
The rule isn’t a formal study. It came out of a call-in show, where a caller asked how much of a nest egg he could safely spend. Ramsey’s answer has since traveled across finance media, usually with a raised eyebrow. I think it helps to separate the claim from the personality. The claim is a piece of arithmetic that anyone can check. The personality is what turned it into a feud. So I’ll start with the arithmetic, then the dollars, and save the shouting match for later. That order keeps the argument honest, since the math is simple and the assumptions are where all the action is.
What exactly did Ramsey say?
He said retirees can withdraw about 8 percent a year if their money earns about 12. His reasoning was that good mutual funds return around 12 percent, the S&P 500 has averaged 11.8 percent and inflation has averaged 4 percent over 80 years, which leaves 8 percent to spend. He made the case after a caller asked about a 3 percent withdrawal rate, which Ramsey called ridiculous. One critic notes the approach assumes a portfolio invested entirely in stocks. That’s the heart of it. The rule only works if the average return shows up as a smooth line. This Dave Ramsey Retirement Advice Is Wrong and Dangerous +2
How does 8 percent look in dollars?
On a $1 million portfolio, 8 percent is $80,000 in the first year. With 4 percent inflation, the second-year withdrawal rises to $83,200 under Ramsey’s assumptions. A 4 percent start would be $40,000, and Bengen’s newer 4.7 percent figure would be $47,000. The gap is big. It’s also why the rule is tempting, because a $1 million target feels reachable. Simple math adds a warning. With no investment growth at all, 8 percent would empty an account in about 12.5 years. Growth changes that, but the figure shows how little room the rule leaves. foolmoney
Why Do Financial Experts Push Back on It?
The objection isn’t that 12 percent is impossible over long stretches. The objection is that you don’t earn an average, you earn a sequence. Retirees spend money during that sequence, not after it. So the order of good and bad years matters more than the headline number. That’s the part the 12-minus-4 shortcut skips. I find this the most useful way to understand the whole debate. Both sides can agree on the history of stock returns and still disagree on whether a person can live on it.
What is sequence of returns risk?
It’s the danger of poor returns arriving early in retirement. When you withdraw while the portfolio is down, you sell more shares at low prices, and less is left to recover. One planning article notes that a 12 percent average still involves big ups and downs, and that constant inflation-adjusted spending through consecutive down years or high inflation can drain a portfolio quickly. A critique from an investment firm makes the same point, that an average of 12 percent doesn’t mean 12 percent each year. I find this the strongest objection. Average returns are a fact about the past, and your retirement happens in one specific order. advisorthornburg
What do Bengen and Morningstar recommend instead?
Their numbers sit well below 8 percent. Bill Bengen, who originated the 4 percent rule, now puts the worst-case safe starting rate at 4.7 percent in his 2025 book. He also says a rate between 5.25 and 5.5 percent looks about right for typical conditions. Morningstar’s 2025 research puts the highest safe starting rate at 3.9 percent for a 30-year retirement with a 90 percent chance of money left, assuming fixed inflation-adjusted spending. Morningstar also found that heavier stock exposure supported lower starting rates, and that portfolios with 30 to 50 percent in stocks supported the highest. So even the optimists sit near 5 percent. Ramsey sits at 8. retirement rule update 4 percent +3
Does the 8 percent rule ever work?
In hindsight, sometimes. One analyst found that an 8 percent withdrawal would have survived every 30-year simulation since 1978. That’s a fair point for Ramsey’s side. But a window starting in 1978 is short and includes long bull markets. The same analyst notes that a fund averaging nearly 12 percent since 1935 rarely landed near that average in any single year. A short stretch of hindsight isn’t a plan. And a plan that works in most years can still fail badly in one. ofdollarsanddataofdollarsanddata
How Can You Plan Retirement Withdrawals More Safely?
I’m not here to tell you what rate to use. The honest answer depends on your age, your other income and how flexible your spending is. But a few habits beat any single number. Start lower than you hope. Review the plan every year. Keep some spending you can cut in a bad market. None of this costs anything, and all of it protects against the sequence problem. If I were building a plan, I’d also count Social Security and any pension first. Then I’d ask how much the portfolio really has to cover.
Should you start lower and stay flexible?
Yes, flexibility is the biggest lever. Morningstar reports that retirees willing to adjust spending could start closer to 6 percent. The trade is that spending moves with the market. In a bad year you cut back. In a good year you can spend a bit more. A cash cushion covering a year or two of expenses helps some people avoid selling stocks at the bottom. I’d treat that as a common planning idea, not a guarantee. Other income lowers the rate you need from savings, so count it before you pick a percentage. retirementliving
How do you test your own plan?
Use a calculator that runs many market scenarios, not one average. Look for Monte Carlo or historical-simulation tools, and test a few bad starts, such as high inflation in year one. Check fees too. One summary notes that each 1 percent in annual costs may reduce a safe withdrawal rate by roughly 0.45 to 0.5 percentage points. Then ask a fiduciary adviser to review the result. A fee-only planner who must put your interests first is the safer choice. That’s general guidance, not personal advice. mezzi
Conclusion
So, what is Dave Ramsey’s 8 rule? It’s a neat piece of arithmetic that assumes a smooth 12 percent return, and it breaks when real markets arrive in a bad order. Bengen’s 4.7 percent and Morningstar’s 3.9 percent are far more cautious, and even flexible plans top out near 6. I’m not saying Ramsey is dishonest. I’m saying the assumptions carry all the weight. Check them against your own life before you trust any single number. I keep wondering how many callers hear the number 8 and stop listening after that. I’d love to know.
FAQs
Is an 8% withdrawal rate safe in retirement?
Most planners say no. Bengen’s worst-case figure is 4.7 percent, and Morningstar’s base case is 3.9 percent for a 30-year retirement. An 8 percent rate has survived some historical windows, but poor early returns or high inflation can drain it.
What is the 4% rule?
You withdraw 4 percent of your savings in the first year of retirement, then raise that dollar amount for inflation each year. It has been a widely accepted standard for over 30 years. Newer research has pushed the figure up or down depending on the method. benzinga
What is the safest withdrawal rate in retirement?
No single number fits everyone. Morningstar’s base case is 3.9 percent for fixed, inflation-adjusted spending over 30 years. Bengen’s worst-case figure is 4.7 percent, and flexible spenders can start higher. Your age and other income matter. morningstar
How much can I withdraw from a $1 million portfolio?
At 4 percent, that’s $40,000 in the first year. At 4.7 percent it’s $47,000, and at 8 percent it’s $80,000. The higher the rate, the greater the risk that the money runs out.
