Here's a scenario most retirement planning completely ignores: two people retire with the same corpus, withdraw the same amount every year, and get the exact same average annual return over 20 years — 8%. One of them runs out of money in year 14. The other still has a growing corpus at year 20. The only difference is the order the good and bad years arrived in. This is sequence of returns risk, and it's one of the most under-discussed dangers in retirement planning.
Why order matters when you're withdrawing money
While you're still investing (accumulation phase), the order of returns genuinely doesn't matter much — a bad year early and a bad year late average out to the same final number, because you're adding money throughout and there's no forced selling. But the moment you start withdrawing from a portfolio — which is exactly what retirement or FIRE does — the order suddenly matters enormously.
If a market crash hits in your first few retirement years, you're forced to sell a larger share of your portfolio to fund the same withdrawal, because your total corpus just shrank. Those extra units you sold at depressed prices can never come back and participate in the eventual recovery — you've permanently locked in the loss on that portion. The exact same crash arriving in year 15 instead of year 1 does far less damage, because by then your corpus has had time to grow a cushion.
A concrete illustration
Imagine ₹1 crore at retirement, withdrawing ₹6 lakh/year, adjusted for inflation. If the first 3 years of retirement include a 30% crash, the number of units sold to cover those withdrawals during depressed prices is much larger than it would be in normal years — permanently reducing the base that has to recover and keep funding withdrawals for the next 20+ years. The same 30% crash landing in year 17 instead barely dents the plan, because the corpus by then is large enough to absorb it without forced heavy selling.
This is why "the market averages 12% a year over the long run" is true and almost irrelevant to whether a specific retiree's plan survives — what matters is which years the bad ones landed in relative to when withdrawals started.
Why this matters more for FIRE than traditional retirement
FIRE (Financial Independence, Retire Early) plans typically assume a 25-40+ year withdrawal period, far longer than a traditional retirement. A longer withdrawal horizon means more total years exposed to the risk of an early bad sequence, and less room to simply "wait out" a crash by delaying retirement, since the whole point of FIRE is having already left work.
What actually reduces this risk
- A cash/bond buffer for the first 2-3 years of expenses: this lets you avoid selling equity at depressed prices during an early crash — you draw from the buffer instead and let the equity portion recover before you touch it again.
- Flexible withdrawal rates: reducing withdrawals in a down year (skip the inflation adjustment, or cut discretionary spending) reduces how many units get sold at low prices — a rigid fixed withdrawal amount is the riskiest approach.
- A more conservative starting withdrawal rate: the popular "4% rule" was derived from historical US sequences and doesn't automatically transfer to every market or every era — a lower starting rate (3-3.5%) gives meaningfully more cushion against a bad early sequence, at the cost of needing a larger corpus upfront.
- Not retiring right after a market peak, if avoidable: this is the hardest one to control, but being aware of it means at least considering a phased transition (part-time work, delayed full withdrawal) if markets look stretched right when you're about to retire.
Plan around this, not just around the average
Our FIRE Calculator helps you work out a target corpus and withdrawal plan — when thinking about how conservative to be with your assumptions, remember that the "average return" number is only half the story; the sequence it arrives in is the other half, and it's the half nobody can control.
