Drawdown strategy

Sequence-of-returns risk: why the order of returns matters

While you are saving, the order of returns barely matters. Once you are withdrawing, it can be the difference between a comfortable retirement and running out.

Sequence-of-returns risk is the risk that poor returns arrive early in retirement rather than late. The average over the whole period can be identical; the outcome is not. It is one of the few genuinely counter-intuitive things in retirement planning, and it is invisible to any calculation that works only with an average.

The demonstration

Take a twenty-year retirement with exactly the same twenty annual returns (twelve years of +15% and eight years of −10%) and ₹6 lakh withdrawn each year from a ₹1 crore corpus. The only difference between the two cases is the order in which those returns arrive.

₹1 crore · ₹6,00,000 withdrawn each year · identical set of 20 returns
Order of returnsBalance after 20 years
Good years first, bad years laterabout ₹63.6 lakh
Bad years first, good years laterabout ₹8.0 lakh

Same returns. Same withdrawals. Same average. An eight-fold difference in what is left, and the second case is close enough to zero that a slightly longer life or one unplanned expense would have ended it.

Why it only bites during drawdown

With no withdrawals, the order genuinely does not matter: multiplication is commutative, so 1.15 × 0.90 and 0.90 × 1.15 give the same result. A pure accumulation projection is indifferent to sequence.

Withdrawals break that symmetry. Selling during a downturn converts a temporary paper loss into a permanent one, because those units are gone and cannot participate in the recovery. Withdrawing ₹6 lakh from a portfolio that has fallen 10% removes a larger share of it than withdrawing ₹6 lakh from one that has risen 15%. Do that for a few consecutive years at the start and the capital base the rest of the plan depends on has been permanently reduced.

The dangerous window is roughly the first five to ten years of retirement, when the corpus is at its largest and the whole remaining plan still has to be funded from it.

What the calculators do and do not show

Every RetirePeace calculator applies a smooth, constant annual return. That is the right simplification for understanding how the inputs interact, because it isolates one variable at a time, but it means sequence risk is not modelled. A projection that survives at a constant 8% might not survive a real sequence averaging 8%.

You can still probe it usefully. Run your plan at your expected return, then run it again two or three percentage points lower. If the lower run fails badly, you are looking at a plan with little tolerance for a poor opening decade, which is exactly the plan sequence risk punishes hardest.

Ways people reduce it

  • Hold some years of spending in cash or short-term instruments. If two or three years of withdrawals do not have to come from growth assets, a downturn can be waited out rather than sold into. This is the whole idea behind the two-bucket strategy.
  • De-risk approaching retirement. Reducing equity exposure in the few years either side of the retirement date lowers exposure at the exact moment the corpus is largest and most vulnerable.
  • Stay flexible about the withdrawal. Trimming discretionary spending during a bad year is the most effective single response available, and it costs nothing to plan for. Plans that assume a rigid inflation-linked income are testing the harshest case.
  • Keep a margin. A 3.5% starting withdrawal rate absorbs a bad opening decade that a 5.5% rate does not. Margin is what buys the freedom to do nothing.

The honest position

Sequence risk cannot be eliminated, only cushioned, and every cushion has a cost: holding cash means giving up growth in the years markets do well. There is no arrangement that captures full market returns while being immune to their order.

What planning can do is make sure you are not relying on the good case without knowing it. If your plan works at your expected return but fails two points below it, you have learned something specific and actionable: the plan needs either a lower withdrawal, a larger corpus, or a structure that lets you avoid selling growth assets at the wrong moment.
