Sequence of Returns Calculator
See how the order of returns changes a retirement portfolio with fixed withdrawals
Sequence of Returns Inputs
US$
Portfolio value at the start (e.g., 1000000)
US$
Fixed amount withdrawn each year (e.g., 50000)
How do you want to provide annual returns?
One value per year, e.g. "22, -4, 8, -18, 30". The same set is also run in reversed order.
This is a deterministic calculator — not a Monte Carlo simulation. It applies a fixed series of annual returns to a portfolio that is making fixed withdrawals, then runs the identical series in reversed order so you can see exactly how much the order alone changes the outcome. Because the two series share the same numbers, they have the same average return.
balance = (balance − withdrawal) × (1 + return)
The withdrawal is taken at the start of each year, before that year's return is applied. If the remaining balance cannot fund the withdrawal, the portfolio is marked as depleted in that year and the ending balance is zero.
Step 1: Enter your starting portfolio value and the fixed amount you plan to withdraw each year.
Step 2: Choose how to supply returns: type a comma-separated list of yearly percentages, or set an average return and let the tool build a realistic up-and-down pattern.
Step 3: In average mode, toggle between "good years first" and "bad years first" to see the two extremes of sequence risk.
Step 4: Click calculate to compare the ending balance for your order versus the reversed order, plus a year-by-year table.
What Is Sequence of Returns Risk?
Sequence of returns risk is the risk that the order in which your investment returns occur — not just their long-run average — determines whether your portfolio lasts through retirement. While you are still accumulating wealth and not withdrawing money, the order of returns is irrelevant: a portfolio left untouched compounds to the same final value no matter which years were good and which were bad. The moment you start taking fixed withdrawals, however, the order suddenly matters enormously. A sequence of returns calculator makes this otherwise invisible risk concrete by letting you compare the same returns arranged in different orders.
The reason is straightforward. When you withdraw a fixed amount each year and the market has just fallen, that withdrawal represents a larger percentage of your shrunken portfolio. You are forced to sell more of your holdings to fund the same lifestyle, permanently reducing the capital base that would otherwise have recovered when markets rebounded. A retiree who suffers a steep loss in their first year of retirement can run out of money years earlier than an otherwise identical retiree who experienced that same loss near the end — even though both earned the exact same average annual return over the full period.
How This Calculator Works: Method and a Worked Example
This calculator is deterministic rather than a Monte Carlo simulation, which means the results are exact and repeatable rather than probabilistic. Each year it subtracts your fixed withdrawal at the start of the year and then applies that year's return to whatever remains, using the rule balance = (balance − withdrawal) × (1 + return). It then takes the identical set of returns, reverses their order, and runs the same calculation a second time. Because the two runs use the very same numbers, their arithmetic average return is identical — so any difference in the ending balance is caused purely by sequence of returns risk.
Consider a worked example. Suppose you start with a $100,000 portfolio, withdraw $10,000 at the start of each year, and experience three annual returns of +30%, 0%, and −30%, in that order. Year one: ($100,000 − $10,000) × 1.30 = $117,000. Year two: ($117,000 − $10,000) × 1.00 = $107,000. Year three: ($107,000 − $10,000) × 0.70 = $67,900. The portfolio ends at $67,900.
Now reverse those returns to −30%, 0%, +30% and keep everything else identical. Year one: ($100,000 − $10,000) × 0.70 = $63,000. Year two: ($63,000 − $10,000) × 1.00 = $53,000. Year three: ($53,000 − $10,000) × 1.30 = $55,900. The portfolio ends at $55,900 — a full $12,000 lower than the first ordering, despite the two scenarios sharing the exact same average return. The only thing that changed was the order, and the early loss in the reversed sequence did the damage.
Why Retirement Withdrawals Turn Average Returns Into a Range of Outcomes
During the accumulation phase, you can largely ignore sequence risk — and in fact a long stretch of poor early returns can even help a regular investor by letting them buy at lower prices. In the retirement withdrawal phase the dynamic inverts. Each withdrawal you take after a market decline crystallises a loss that can never be recovered, because those dollars are no longer in the market to participate in the rebound. The larger your withdrawal rate relative to the portfolio, the more punishing a poor opening sequence becomes.
This is the central reason the well-known 4% rule from the Trinity Study is set where it is: it was calibrated against historical return sequences, including the worst real-world starting years, so that a balanced portfolio could sustain inflation-adjusted withdrawals for a 30-year retirement. A higher withdrawal rate leaves far less margin for a bad opening decade. You can use the calculator above to test how raising or lowering your annual withdrawal widens or narrows the gap between the best-case and worst-case orderings.
How to Manage Sequence of Returns Risk in Retirement
There is no way to eliminate sequence risk entirely, but several practical strategies reduce it. Holding one to three years of planned spending in cash or short-term bonds — sometimes called a cash buffer or a bond tent — lets you avoid selling equities immediately after a market drop. A flexible withdrawal approach that trims spending in down years protects the capital base when it is most vulnerable. Lowering your initial withdrawal rate and keeping a globally diversified portfolio both add resilience. Because the danger is concentrated in the first five to ten years of retirement, that early window deserves the most conservatism.
Earning some income in the early years of retirement is one of the most effective defences, because it directly reduces how much you must withdraw from a depressed portfolio. This is the structural advantage behind semi-retirement strategies. Our Barista FIRE calculator shows how part-time income lowers the portfolio you need and cushions the early-retirement years that carry the most sequence risk. To see how a withdrawal-rate assumption translates into a target portfolio in the first place, the present value calculator is a useful companion.
On the accumulation side, the order of returns barely matters, which is why disciplined, automated investing works so well for building the portfolio you will eventually draw from. Our compound interest calculator and dollar-cost averaging calculator both model how steady contributions grow a portfolio before retirement begins.

Frequently Asked Questions About Sequence of Returns Risk
Sequence of returns risk is the danger that the ORDER in which investment returns occur — not just their average — determines whether a portfolio survives. It matters specifically when you are withdrawing money, such as in retirement. A run of poor returns in the first few years, combined with withdrawals, can permanently shrink the capital base so that later good years have less money left to compound. Two retirees with the exact same average annual return can end up with very different balances purely because of the order of their returns.
When you are not withdrawing, order does not change the final balance — multiplication is commutative, so a portfolio left untouched ends at the same value regardless of return order. The order matters only because withdrawals interact with it. A withdrawal taken after a market drop removes a larger percentage of your remaining capital, locking in losses and leaving fewer dollars to recover when markets rebound. Good early returns let you withdraw from a larger base, preserving more capital.
The calculator is deterministic, not a Monte Carlo simulation, so the results are exact and repeatable. It takes your initial portfolio, a fixed annual withdrawal, and a series of yearly returns. Each year it subtracts the withdrawal at the start of the year, then applies that year's return: balance = (balance − withdrawal) × (1 + return). It then runs the identical set of returns in the given order and in fully reversed order, so you can compare two ending balances that share the exact same average return.
Common approaches include holding one to three years of spending in cash or short-term bonds so you avoid selling equities after a drop (a cash buffer or bond tent), using a flexible withdrawal strategy that reduces spending in down years, lowering the initial withdrawal rate, and diversifying across asset classes. The risk is concentrated in the first five to ten years of retirement, so the early years deserve the most caution. Part-time income early in retirement also reduces the withdrawals you must take from a depressed portfolio.
Yes. The larger your withdrawals relative to the portfolio, the more damage poor early returns can do, because you are selling a bigger share of a shrinking base. A portfolio that withdraws 3% per year is far more resilient to a bad opening sequence than one withdrawing 6%. This is the core reason the classic 4% rule exists — it is calibrated so that even historically bad return sequences did not deplete a portfolio over a 30-year retirement. You can use this calculator to test how different withdrawal amounts change the gap between the best-case and worst-case orderings.
