Understanding Sequence of Returns Risk and Its Impact on Retirement

Sequence of returns risk is the danger that the order of your investment returns, not just their average, damages your portfolio once you start withdrawing money. Two retirees can earn the same average return, yet the one who hits a market slump early in retirement can run out of money years sooner.

This page is for people approaching retirement, recent retirees, and anyone building a withdrawal plan. You will see how the risk works with a worked example, why timing matters more than averages, and practical strategies to protect your income. The material is educational, not financial advice, so review your own numbers before acting.

What is sequence of returns risk?

While you are saving, the order of annual returns barely matters. A bad year followed by a good year lands you in roughly the same place as the reverse. The math changes the moment you begin withdrawing. Each withdrawal locks in losses during down years, leaving fewer shares invested for the recovery that follows.

That is the essence of sequence of returns risk: the same set of yearly returns, shuffled into a different order, produces very different outcomes once money flows out of the portfolio. Charles Schwab's overview of sequence-of-returns risk makes the same point: timing matters, and early-retirement losses combined with withdrawals can do outsized, lasting damage.

Average return tells you almost nothing about this danger. A portfolio averaging 6% per year can fail if the worst years arrive first, while another with the same average survives comfortably because its losses came late.

Why sequence of returns risk matters for your retirement income

Consider two retirees, Anna and Ben. Each starts with $500,000, withdraws $25,000 per year, and earns the same three returns over three years, just in reverse order.

Same returns, same average, same withdrawals. Ben simply met his bear market later and finishes ahead of Anna. Stretch this gap over a 30-year retirement, with inflation-adjusted withdrawals, and the early-loss path can exhaust a portfolio a decade sooner. The risk concentrates in the years just before and just after your retirement date, a window often called the fragile decade. Strong returns in that window can set you up for life; deep losses there can force painful cuts even if markets later recover.

How sequence of returns risk can affect when you retire

Because the fragile decade dominates outcomes, your retirement date itself becomes a risk decision. Retiring into the teeth of a bear market means selling depressed assets to fund living costs from day one. Retiring after a long bull run means your balance looks fat, but valuations may be stretched and future returns thinner.

You cannot time markets, but you can build flexibility around the date. Options include working one or two more years if markets fall just before your target date, phasing into part-time work so withdrawals start smaller, or delaying large discretionary spending in the first years. Flexibility on timing and spending is itself a hedge: every year you avoid selling into a slump leaves more shares invested for the recovery.

Strategies to mitigate sequence of returns risk

No single tactic removes the risk, but combining several can blunt it:

• Hold a cash or short-term bond buffer. One to three years of planned withdrawals in stable assets lets you avoid selling stocks during a downturn.
• Use a flexible withdrawal rule. Trimming withdrawals after bad years, even modestly, dramatically improves survival odds compared with rigid inflation-adjusted spending.
• Rebalance on schedule. Rebalancing forces you to sell what held up and buy what fell, refilling the buffer and keeping risk in line.
• Diversify across assets. A mix of stocks, bonds, and cash smooths the path of returns, which matters more than maximizing the average once withdrawals begin.
• Segment your money by time horizon. A bucket approach dedicates near-term money to safe assets and long-term money to growth, matching each dollar to when you will need it.
• Consider guaranteed income for essentials. Covering fixed costs with predictable income sources reduces how much you must withdraw from volatile assets in any given year.

Each tactic has trade-offs. Buffers drag on returns in good times, spending rules require discipline, and guarantees carry costs and terms you should verify carefully before committing.
