The Dave Ramsey 12 percent retirement rule assumes your investments earn 12% a year, so you can spend about 8% of your nest egg every year in retirement. My view is that 12% is too optimistic to plan around, and with the S&P 500 down 5.0% over the past month (Yahoo Finance, as of November 6, 2026), an 8% withdrawal leaves you very little room if the market falls early in your retirement.
Below I explain where the number comes from and run the math on $500 a month and on a $1 million portfolio. I also show what a bad first year does to the plan and what I’d use instead.
Key takeaways
- An average return of 12% can turn into about 9.4% a year of real growth. Example: +30%, −20%, +26% averages 12% but turns $10,000 into $13,104, not $14,049 (my arithmetic).
- At an 8% withdrawal, a $1,000,000 portfolio that drops 20% in year one falls to $736,000, and the same $80,000 withdrawal becomes 10.9% of the balance (my arithmetic).
- US inflation was 3.74% year over year in September 2026 (Bureau of Labor Statistics), so an $80,000 withdrawal adjusted for inflation becomes $82,992 the next year.
- The S&P 500 fell 5.0% and the Nasdaq Composite 9.61% over the past month, to November 6, 2026 (Yahoo Finance).
What is the Dave Ramsey 12 percent retirement rule?
The rule has two parts, and people mix them up. In the saving years, Ramsey tells listeners they can expect about 12% a year from good growth-stock mutual funds, and he uses that number in his savings projections. In retirement, he has said on his show that if your money earns around 12%, you can take out 8% a year and still leave a cushion for inflation and bad years.
So you’ll see “the 12% rule” used for two things: a return assumption and a withdrawal rate. The return assumption is mostly harmless while you’re 30 and saving. The withdrawal rate gets dangerous once you stop working, because you’re selling shares to pay your bills.
Compare it with the 4% rule, from William Bengen’s 1994 research on historical US stock and bond returns. Bengen found that starting withdrawals at about 4% of the portfolio, then raising them for inflation, held up through the worst periods he tested. Ramsey’s 8% is double that, and that gap is the reason financial planners argue with him.
Where does the 12% number come from?
Ramsey points to the long-run history of the S&P 500 and says that over long periods, the index has averaged returns close to 12%. The figure he uses is an arithmetic average: add up each year’s return and divide by the number of years.
There are two problems with treating that as your own expected return. The first is the gap between average and compound growth, which I cover in the next section. The second is costs and behavior. Actively managed mutual funds charge fees, and real investors buy late and sell in panics. I’ve done it myself with crypto in 2018, and my returns were nothing like the chart.
Inflation matters too. A 12% nominal return in a year when consumer prices rise 3.74%, the September 2026 CPI figure from the Bureau of Labor Statistics, buys you about 8% more stuff, not 12%. Ramsey’s plan treats the 4-point gap between 12% and 8% as the inflation cushion. That works only if the 12% actually shows up.
Why an average return of 12% doesn’t mean 12% growth
What matters for your account is the compound annual growth rate, and it’s always lower than the simple average when returns jump around. Here’s a three-year example with simple numbers.
- Year 1: +30%. $10,000 becomes $13,000.
- Year 2: −20%. $13,000 becomes $10,400.
- Year 3: +26%. $10,400 becomes $13,104.
Add 30, minus 20 and 26, then divide by three, and you get an average of exactly 12%. But $10,000 growing at a steady 12% would reach $14,049. Your actual result, $13,104, works out to about 9.4% a year.
That difference of 2.6 points sounds small, but it compounds over 30 years. The bigger the swings, the bigger the gap. A loss of 50% needs a gain of 100% just to get back to even, and the average return hides that.
What 12% vs 7% means for $500 a month
Return assumptions matter most over long saving periods. Say you invest $500 a month for 30 years, $180,000 of your own money in total, compounded monthly.
- At 12% a year, you’d end up with about $1.75 million.
- At 7% a year, you’d end up with about $610,000.
That’s a gap of roughly $1.14 million from the return assumption alone. If you plan around 12% and get 7%, you find out in your late 50s, when it’s too late to fix by saving more.
To be fair to Ramsey, his saving advice is sound: get out of debt, invest 15% of household income for retirement, and don’t stop. If you follow that, you’re in better shape than most people, whatever return you assume. My problem is only with the projection. I’d run my own plan at 6% to 7% and treat anything above that as a bonus. If you hold a broad index fund, my guide to how an S&P 500 index fund works shows what you actually own.
How the 8% withdrawal works in retirement, step by step
Here’s the retirement half of the rule with a $1,000,000 portfolio.
- In year one, you withdraw 8%, which is $80,000.
- The remaining $920,000 stays invested, mostly in stock funds, as Ramsey recommends.
- If the portfolio earns 12%, it grows to $1,030,400 by year end. You took your income and still have more than you started with.
- In year two, you raise the withdrawal for inflation. At September’s 3.74% CPI rate, $80,000 becomes $82,992.
When returns arrive smoothly, this works fine. The trouble is that withdrawals are fixed in dollars and returns aren’t. Every dollar you sell during a down year is a dollar that can’t recover when prices come back. Planners call this sequence of returns risk: the same average return can have very different outcomes depending on the order the good and bad years come in.
What one bad first year does to an 8% withdrawal plan
This table shows a $1,000,000 portfolio at three withdrawal rates. The withdrawal comes out at the start of the year, then the market falls 20%. You keep taking the same dollar amount in year two.
| Withdrawal rate | Year-one withdrawal | Balance after a 20% fall | Same dollars as % of new balance | Gain needed to get back to $1M |
|---|---|---|---|---|
| 4% | $40,000 | $768,000 | 5.2% | 30.2% |
| 6% | $60,000 | $752,000 | 8.0% | 33.0% |
| 8% (Ramsey) | $80,000 | $736,000 | 10.9% | 35.9% |
With the 4% plan, one bad year moves you to roughly a 5% withdrawal rate, which is uncomfortable but survivable. With the 8% plan, you’re now selling almost 11% of your portfolio a year. If a second bad year follows, the math gets ugly fast.
This has happened before. Anyone who retired in early 2000 went through three straight losing years for the S&P 500, in 2000, 2001 and 2002, while still paying their bills from the portfolio. A 4% retiree came out of that bruised. An 8% retiree who kept spending through it had sold a large share of their holdings near the bottom.
How today’s markets test the 12% rule
You don’t need a hypothetical. These are the latest numbers I have, from Yahoo Finance for markets and from US government sources for the economy.
| Measure | Latest | 1-month change | Source, date |
|---|---|---|---|
| S&P 500 | 7,376.86 | −5.0% | Yahoo Finance, Nov 6, 2026 |
| Nasdaq Composite | 24,579.43 | −9.61% | Yahoo Finance, Nov 6, 2026 |
| KOSPI | 5,018.85 | −21.39% | Yahoo Finance, Nov 9, 2026 |
| US 10-year Treasury yield | 4.86% | −7.11% | Yahoo Finance, Nov 6, 2026 |
| US CPI inflation (year over year) | 3.74% | n/a | BLS, September 2026 |
| Fed funds effective rate | 3.88% | n/a | New York Fed, Nov 5, 2026 |
| US unemployment rate | 4.1% | n/a | BLS, October 2026 |
Here’s a worked example. A new retiree with $1,000,000 in S&P 500 funds who took $80,000 a month ago, then caught the 5.0% drop, would be at about $874,000. The same $80,000 next year is already 9.2% of the balance, and that’s after a fairly ordinary pullback. Someone heavy in Nasdaq stocks, down 9.61%, or Korean stocks, with the KOSPI down 21.39%, is in a much worse position.
Two other numbers stand out. Inflation at 3.74% means the cushion in Ramsey’s plan between 12% and 8% gets used up faster. And a 10-year Treasury yield of 4.86% means safe bonds pay something real again, so you don’t have to rely only on stocks to fund your spending. MarketWatch also ran a piece this week on how concentrated the S&P 500 has become in AI stocks. That’s worth reading if your whole retirement sits in one index.
Common mistakes people make with the 12% rule
The biggest one is using 12% in a retirement calculator and then treating the result as a plan. Most online calculators use a single fixed return, so they can’t show sequence risk at all. If your plan works only at 12%, it doesn’t really work.
Another is mixing up nominal and real returns. A calculator that shows $1.75 million in 30 years is quoting future dollars. At 3.74% inflation, the September 2026 CPI rate, prices roughly triple over 30 years, so that pile buys far less than it sounds like.
People also forget about taxes and fees. An $80,000 withdrawal from a traditional 401(k) or IRA is taxable income, so what you can spend is less. Brackets change, so check the current figures on IRS.gov rather than trusting a number from a blog post. If your savings are in a workplace plan, my piece on what a 5% market fall does to a 401(k) goes through the dollar math.
The last one is chasing yield to hit 8%. Some retirees buy high-yield funds so they can live on the payouts and never sell shares. A high payout can come from a falling share price or from returning your own capital, which I explain in how dividend yield works and when it’s a trap.
Alternatives to Ramsey’s 8% withdrawal plan
You don’t have to choose between Ramsey’s 8% and a rigid 4%. These are the approaches I’d look at.
- Start at 4% and raise it for inflation. This is the Bengen approach. It’s conservative, and in good markets you may die with a lot of money left over.
- Use guardrails. Start somewhere between 4% and 5%, cut spending by a set amount after a bad year, and give yourself a raise after a good one. It’s more work, but it adjusts to whatever the market does.
- Use a cash bucket. Keep one to two years of withdrawals in cash or short Treasuries and refill it from stocks only after good years. With the fed funds rate at 3.88% (New York Fed), cash isn’t earning zero while you wait.
- Buy guaranteed income. An annuity or delaying Social Security turns part of your savings into a paycheck that doesn’t depend on markets. Fees and terms vary a lot. MarketWatch’s recent reader question, is an annuity the right move in this market, shows what to ask an adviser.
What I do myself is plan my numbers on the conservative side and save hard, as Ramsey says. I just don’t build my retirement spending on his return figure.
FAQ
What is Dave Ramsey’s 12 percent rule in simple terms?
It’s Ramsey’s assumption that good growth-stock mutual funds can earn about 12% a year over the long run. He uses it both to project savings and to argue that retirees can safely withdraw about 8% a year. The 8% part is the most controversial.
Is a 12% return realistic?
Some years beat 12% easily and some lose money. Over long periods, the compound return investors actually get is lower than the simple average Ramsey quotes, especially after fees and inflation. In my example, an average of 12% turned into about 9.4% a year of real growth.
Is the 8% withdrawal rate safe?
It can work if returns come in strong early in retirement. The risk is a bad first few years: a 20% fall on a $1,000,000 portfolio with an $80,000 withdrawal leaves $736,000, and the same withdrawal becomes 10.9% of what’s left. Most retirement research supports starting rates closer to 4%.
How is the 12% rule different from the 4% rule?
The 4% rule comes from William Bengen’s 1994 study and sets the starting withdrawal so it survived the worst historical periods. Ramsey’s 8% assumes average returns, while Bengen’s 4% assumes bad luck. On $1,000,000, that’s $80,000 versus $40,000 in the first year.
What return should I use in a retirement calculator?
I use 6% to 7% for a stock-heavy portfolio and check whether the plan still works at 5%. If you want to see real dollars, subtract inflation, which was 3.74% in September 2026 according to the BLS, or use a calculator that shows inflation-adjusted values.
Does the 12% rule apply to crypto?
No. Crypto has no long return history to base an average on, and the swings are much larger. Bitcoin is down 10.98% over the past month and Ethereum 16.11% over 30 days (Yahoo Finance and CoinGecko data). A withdrawal plan built on crypto prices would face far more sequence risk than one built on stocks.
What I’d watch before trusting any withdrawal rate
The next US CPI release is the one I care about most. If inflation stays near the September reading of 3.74%, inflation-adjusted withdrawals rise faster and the cushion in Ramsey’s plan shrinks. I’d also keep an eye on the 10-year Treasury yield at 4.86%. While it stays near that level, bonds and short Treasuries are a real way to fund the first years of retirement without selling stocks in a slump.
On stocks, the question is whether the 5.0% monthly drop in the S&P 500 stays a pullback or becomes something longer. Nobody knows yet. That uncertainty is the reason I’d size withdrawals for the bad case and let good years be a pleasant surprise.
