This sequence of returns risk calculator takes one list of yearly returns and plays it in two directions while you withdraw money. Enter a starting portfolio, a year-one withdrawal that rises with inflation, your age, and either your own returns or a built-in history. It reports each order’s ending balance, the age the money runs out, and the dollar gap between them.
The default replays S&P 500 total returns for 2000 through 2024: $1,000,000, and $40,000 drawn in the first year of retirement, raised 3% a year from age 65. In the order they happened, the portfolio ran out of money at 88. Flip the same 25 years and it ends at $3,655,647. A checkbox adds worst-first and best-first orders.
Sequence of Returns Risk Calculator
Run one set of yearly returns forward, reversed, and sorted worst first while you withdraw, and see how the order alone changes the ending balance and the age the money runs out.
Results replay a fixed list of past or user-entered annual returns in different orders; they are not probabilities and not a forecast. Built-in data: S&P 500 total returns and 10-year Treasury returns from Aswath Damodaran, NYU Stern (January 2026 update). Taxes, fees, and required minimum distributions are not modeled. Educational only, not investment advice.
What Is Sequence of Return Risk?
Sequence of return risk is the danger that negative returns land at the beginning of retirement, just as withdrawals start. Two retirees can earn the identical average return over 25 years and finish worlds apart, because one met the bear market at 66 and the other at 81.
The 2000 to 2024 history averages 9.25% a year (simple) and compounds at 7.62% in every order. Without withdrawals, $1,000,000 grows to $6,272,841 however you arrange the years, since multiplication ignores order. Take money out and that symmetry breaks: shares sold after a 20% loss never get the rebound.
So the order of returns matters most to a retiree. During accumulation, steady contributions buy cheap shares after early losses; the damaging years are the late ones, when the balance is largest. In drawdown the impact of sequence peaks right after the paychecks stop.
Retiring in January 2000: Listed Order vs Reversed
The built-in data is Aswath Damodaran’s Historical Returns on Stocks, Bonds and Bills table from NYU Stern, updated January 5, 2026. We transcribed its S&P 500 (with dividends) and 10-year Treasury columns for 2000 to 2024 and checked each figure against his spreadsheet.
In year 1 the index fell 9.03%, then 11.85%, then 21.97%. By the end of 2002 our investor held $539,242 while drawing a rising retirement income. Reversed, the first three years were 2024, 2023, and 2022 (up 24.88%, up 26.06%, then an 18.04% loss), and the balance stood at $1,161,287.
| Order (same 25 returns) | Outcome | Total withdrawn |
|---|---|---|
| As it happened, 2000 first | Empty at age 88 | $1,325,291 |
| Reversed, 2024 first | $3,655,647 at 90 | $1,458,371 |
| Worst years first | Empty at age 73 | n/a |
| Best years first | $4,736,942 at 90 | n/a |
Of the market crashes in the data, 2008 (a 36.55% loss) was the worst. It arrived in year 9 of the listed order and year 17 of the reversed one. Early, it hit a shrunken account; late, an account past $5.8 million.
How much could the 2000 start support, other inputs unchanged?
| Year-one draw | 2000 first | 2024 first |
|---|---|---|
| $30,000 (3%) | $1,430,932 left | $4,309,945 left |
| $35,000 (3.5%) | $623,948 left | $3,982,796 left |
| $40,000 (4%) | Empty at 88 | $3,655,647 left |
| $45,000 (4.5%) | Empty at 83 | $3,328,497 left |
| $50,000 (5%) | Empty at 80 | $3,001,348 left |
A balanced asset allocation softens the blow without erasing it. With 60% stocks and 40% Treasuries, rebalanced yearly, the average annual return drops to 7.17%. At $40,000 the listed order ends with $932,254 and the reversed one with $2,088,427. Sorted worst first, it runs dry at 80.
The Retirement Red Zone Around Your Retirement Start
Many planners call the stretch about five years either side of the retirement date the retirement red zone. The balance is near its peak and no salary is left to refill it. A downturn inside that retirement window does the most damage per dollar lost.
We ran a test to show it. Keep every year in its historical slot except the first five years, and play only those backward (2004, 2003, 2002, 2001, 2000). Nothing after 2004 changes. The portfolio no longer dies at 88; it reaches 90 with $266,125. The first 5 years alone decided the outcome.
A bad sequence of returns late in life mostly trims what heirs receive. That’s why the first ten years deserve more attention than the last ten.
Monte Carlo Odds vs One Replayed History
Many online retirement calculator tools run a Monte Carlo simulation: thousands of random paths and a success percentage. You never see which path failed or why.
A replay is the opposite. Every run gives the same answer, and the portfolio value in 2002 tells the whole story. What it can’t do is give the odds of a future sequence of return risk event, so treat it as a stress test for your risk profile, not a forecast of market returns or market volatility.
Our safe withdrawal rate calculator takes the other angle: it solves for the highest starting draw given your horizon and mix, with a fixed two-year slump up front. Size the draw there; see why the early years carry the real risk here.
Ways to Shield a Portfolio From an Early Downturn
None of these removes sequence risk. Each lowers the chance that a downturn forces a sale at the bottom.
A cash bucket
Hold two to three years’ worth of expenses in cash or short Treasuries, and spend it after bad years instead of selling stocks. Refill it in good years. The 2000 start had three losing years in a row, so even two years of cash ran short. More than three years of living expenses in cash drags on long-run growth.
Guardrails on spending
Jonathan Guyton and William Klinger tested decision rules in “Decision Rules and Maximum Initial Withdrawal Rates” (Journal of Financial Planning, March 2006). Raises track inflation, capped at 6%. No raise follows a year with a negative total return if the withdrawal rate would then exceed the initial withdrawal rate. If the rate climbs more than 20% above where it started, that year’s draw drops 10%, a rule that stops 15 years before the plan ends. If it falls more than 20% below, the draw rises 10%. With at least 65% equities, they found starting rates of 5.2% to 5.6% sustainable over 40 years at their 99% confidence standard.
Choose guardrails in the tool and the 2000 start survives to 90 with $1,977,292. The price was income: the draw fell to $30,035 by year 5 and didn’t pass $40,000 again until year 21. It works best when discretionary spending such as travel, not rent, absorbs the cut.
A rising equity glide path
Wade Pfau and Michael Kitces reported in “Reducing Retirement Risk with a Rising Equity Glide Path” (January 2014) that a portfolio starting at 30% stocks and finishing at 60% performed better than one holding 60% throughout. Starting conservative cuts downside risk early in retirement, then adds risk assets once the fragile years pass. Your risk tolerance still has to live with a bolder mix at 80.
A guaranteed income floor
Social Security, a pension, or an income annuity pays bills without selling anything. The more living expenses a guaranteed income stream covers, the smaller the draw that has to survive a crash. Weighing a pension lump sum against monthly checks? Sequence risk is a point for the checks. Delaying Social Security works the same way; see the break-even ages for claiming.
A lower starting rate
In the table above, 3.5% survived the 2000 start with $623,948 left. A 4% safe withdrawal rate comes from past data, not a promise, and early retirement needs more margin because the time horizon is longer.
Reading the Withdrawal Results Without Overreacting
The dollar gap isolates order, the one thing an average hides. Don’t read the reversed result as likely; read the listed and worst-first results as what your retirement plan must survive.
Enter your own list to test a real worry, say three losing years followed by your expected rate of return each year for 25 years. Write a loss in parentheses, such as (20). The tool shows whether the balance would deplete, when, and how much you’d withdraw in total. Figures are nominal and pre-tax, so your investment returns here compare orders rather than set a retirement financial budget.
Choose the withdrawal strategies you’d really follow before you retire, not in the middle of a bear market. Then rerun the sequence of returns risk calculator each year with your real balance.
Frequently Asked Questions
What is the biggest risk in retirement?
For anyone living off investments, a steep loss in the first few years of retirement while withdrawals continue. That, more than a low average, is what makes a sound plan run out of money.
Does sequence risk matter if I don’t withdraw?
No. With nothing going out, every order of the same returns ends at the same balance. SORR only exists once you start drawing from the account, which is why sequence of return risk is a retirement problem.
Do positive returns later make up for early losses?
Only partly, because good returns compound on a smaller base. In the 2000 replay, 2019’s 31.21% gain added about $49,000 to the listed portfolio and about $498,000 to the reversed one.
