Sequence of Returns Risk Calculator

Two retirees start with identical portfolios and earn the same average annual return — but one enters into a bear market, the other into a bull market. Enter your numbers to see how much the timing difference costs year by year, and whether your plan can survive a bad sequence.

Why the order of returns matters more than the average

During your working years, return sequence barely matters. You buy shares over time — a bad year just means you accumulate more shares cheaply, and a recovery year hands you a gain on the full balance. Dollar-cost averaging works for you.

Retirement inverts that logic. Now you're selling shares each year to fund spending. A 30% crash in year one forces you to liquidate a large number of shares at the bottom. Those shares are gone permanently — they can't recover. When the market bounces back, your balance is lower than it would have been if the crash had come in year 15 instead. The good and bad sequences produce the same average return over 30 years but arrive at completely different ending balances.

The critical 10-year window

Research by Michael Kitces and Wade Pfau shows that sequence risk is most acute in years 1–10 of retirement. A severe bear market in years 15–25 has far less impact — you've had time to build a cushion and your remaining withdrawal horizon is shorter. This asymmetry is why standard accumulation advice ("stay invested, ride it out") doesn't map directly to distribution planning.

The rough rule: if a bad sequence hits while your withdrawal rate is above 4%, you face real depletion risk that recovers take decades to correct. If a good sequence pushes your portfolio well above the starting value in years 1–5, a later crash has much less power to deplete it.

Five ways to reduce your exposure

1. Cash buffer (bucket strategy)

Hold 1–2 years of spending in cash before retirement begins. In a down year, spend from cash instead of selling equities. The equity portfolio recovers before you need it. A simple but powerful sequence-risk hedge. Size your buckets →

2. Guyton-Klinger guardrails

Instead of withdrawing a fixed dollar amount, flex spending based on portfolio performance. The capital-preservation rule cuts withdrawals 10% if the portfolio falls below a floor. The prosperity rule lets you take a 10% raise when markets run well. Bad sequences trigger automatic cuts that slow the drawdown. Simulate the guardrails →

3. Bond tent / rising equity glide path

Enter retirement at a higher bond allocation (40–50% equities) than you'd hold 10–15 years later. You're least exposed to equity crashes when you're most vulnerable to sequence risk; then let equities rise as you move through the danger zone. Bond tent research →

4. Delay Social Security to 70

A larger SS benefit is sequence-proof income. Delaying from 62 to 70 increases the monthly benefit by 76% and provides guaranteed income regardless of what the market does. The tradeoff — spending down the portfolio faster in your 60s — is worth it when the SS income floor reliably covers essential expenses. Model the claiming math →

5. Income floor strategy

Dedicate enough of your portfolio to guaranteed sources — delayed SS, a SPIA, or a TIPS ladder — to cover essential expenses. With necessities funded, you can hold equities through a crash without forced selling. The sequence-risk problem largely disappears for the floor portion of your income. Floor strategy guide →
