Sequence of Returns Risk Explained: Why Order Matters in Retirement
Short answer: sequence of returns risk is the danger that poor market returns arrive early in retirement, while you are withdrawing, which shrinks the portfolio more than the same returns arriving later. In an example with ten years of identical returns in opposite order, both portfolios would grow to $1,681,693 with no withdrawals, but with $50,000 withdrawn each year the bad-start one ends at $816,821 and the good-start one at $1,131,467.
Key takeaways
- While you save, the order of returns does not change the final balance. While you withdraw, it can change it a lot.
- The same average return can leave you with $816,821 or $1,131,467 depending on the order.
- The risk is highest in the first five to ten years of retirement.
- A cash buffer, flexible spending, a lower starting rate and gixed income all reduce it.
What does the risk look like in numbers?
Use ten years of yearly returns: -20%, -10%, 5%, 10%, 15%, 18%, 12%, 8%, 10% and 12%, and the same set in reverse order. Both have the same average and the same compound result. Start with $1,000,000.
| Case | Order of returns | Ending balance with no withdrawals | Ending balance with $50,000 a year withdrawn |
|---|---|---|---|
| Bad start | Falls first, then gains | $1,681,693 | $816,821 |
| Good start | Gains first, falls last | $1,681,693 | $1,131,467 |
With no withdrawals the order does not matter: both end at $1,681,693. With withdrawals, the bad start leaves $314,646 less. In the bad start, early withdrawals come out of a portfolio that has just fallen, so fewer shares are left to enjoy the later gains.
Why does it matter for retirees and not savers?
A saver adds money, so a fall early means buying cheaply, and the final balance depends on the total return. A retiree takes money out, so a fall early means selling cheaply. The units sold early cannot take part in the recovery. The flows are opposite, and so is the effect. See will a market crash ruin my retirement.
When is the risk highest?
- The first five to ten years of retirement, when the portfolio is largest and years of withdrawals still lie ahead.
- Early retirement, where the horizon is long and there is more time for a bad stretch.
- High withdrawal rates. A 5% start has far less room than 3%.
- All-stock portfolios, which fall furthest, though bonds and cash grow less.
How do you reduce it?
| Tool | How it works |
|---|---|
| Cash buffer (1 to 2 years) | Spend from cash in a downturn so stocks can recover |
| Flexible spending | Cut after bad years, restore after good ones |
| Lower starting rate | 3% to 3.5% leaves a thicker cushion |
| Gixed income | Social Security or a pension lowers what you draw |
| Bond tent or glide path | Hold more bonds around retirement, then raise stocks later |
| Part-time work | Even a few years of income reduces early withdrawals |

How do you test your own plan?
- Run your plan with average returns.
- Run it again with a 25% to 30% fall in the first one or two years.
- See whether the money still lasts to your planning age, 90 to 95.
- If it does not, change one lever from the table and rerun.

How much does a cash buffer help?
Take the bad-start case. Instead of withdrawing $50,000 from the portfolio in the first two years, hold $100,000 in cash outside the portfolio and spend that, so the other $900,000 is untouched while markets are down. From year 3 on, withdraw $50,000 from the portfolio as before.
| Approach (bad start) | Balance after 10 years |
|---|---|
| All $1,000,000 invested, $50,000 withdrawn each year | $816,821 |
| $900,000 invested and $100,000 cash spent in years 1 and 2 | $837,842 |
The buffer improves the result by about $21,000 over ten years in this example. It is not a miracle, since cash earns little and the portfolio is smaller, but it protects against selling at the lowest prices. Its value is larger when the fall is deeper or lasts longer, and it also gives you peace of mind. Combine it with flexible spending and a modest starting rate.

What mistakes ignore sequence risk?
- Planning only with an average return, which hides the effect of order.
- Assuming it only matters in a crash. A long weak stretch causes the same damage.
- Retiring with an all-stock portfolio and no cash buffer.
- Starting with a high withdrawal rate and no rule for cutting back.
- Forgetting that part-time income early on is one of the cheapest protections.

Frequently asked questions
What is sequence of returns risk?
The risk that poor returns arrive early in retirement while you are withdrawing, which depletes the portfolio faster than the same returns in a different order.
Why does the order of returns matter in retirement?
Because withdrawals sell shares at the prices of the day. Selling early at low prices removes shares that cannot join a later recovery. In the example, the order changed the ending balance from $816,821 to $1,131,467.
Does sequence risk matter while I am saving?
Not for the final balance. When you add money regularly, a fall early means buying cheaply, and the order does not change the total return.
How can I reduce sequence of returns risk?
Hold a cash buffer of one to two years of spending, stay flexible, start with a lower withdrawal rate, rely on gixed income and consider part-time work early in retirement.
When is sequence risk highest?
In the first five to ten years of retirement, especially for early retirees and anyone with a high withdrawal rate or an all-stock portfolio.
