Accumulation vs Drawdown
Building the corpus is half the job; spending it down without running out is the other half.
Retirement has two distinct phases with opposite challenges. Accumulation is building the corpus during your working years; *drawdownThe worst peak-to-trough fall in a portfolio.* (decumulation) is spending it down through retirement. Most people plan only the first and are blindsided by the second.
The crucial realisation: spending a corpus down without running out is a harder, different problem than building it up — and the rules reverse. In accumulation, *volatilityThe size of price swings — not their direction. is your friend (you’re buying, so market dips let you accumulate cheaply, and time smooths the ride) and your big lever is savings rateThe share of your income you save and invest.*. In drawdownThe worst peak-to-trough fall in a portfolio., *volatilityThe size of price swings — not their direction. becomes your enemy: you’re now selling to fund expenses, so a downturn forces you to sell more units at low prices — permanently shrinking the corpus (this is sequence risk, next lesson). Your levers flip too — now it’s withdrawal rateHow much you can withdraw yearly in retirement without running out. and asset mixHow you split money across equity, debt, gold and other assets.* that decide survival. This is why a retiree can’t just keep the same aggressive all-equityA unit of ownership in a company. portfolio: a crash early in drawdownThe worst peak-to-trough fall in a portfolio., combined with withdrawals, can be devastating. The drawdown phase demands its own strategy — a sustainable withdrawal rateHow much you can withdraw yearly in retirement without running out. (the 4% rule debate), a more balanced allocation (some stability to draw from in down years so you don’t sell equities at a low), and a reliable income structure (next lesson). Plan both phases: accumulating ₹5 crore is only half the job; making it last 30 years is the other, often-neglected half.
- Two phases — accumulation (build the corpus) and drawdownThe worst peak-to-trough fall in a portfolio./decumulation (spend it down); opposite challenges.

- Implication — retirees need a balanced allocation and a withdrawal plan, not the same aggressive portfolio; plan both phases.
ExampleDuring accumulation, a 2020-style crash was a gift — Anil’s SIPs bought cheap and recovered. But imagine that crash in his first year of retirement: now he’s selling units 30% down to pay bills, locking in losses the recovery can’t fully undo. Same crash, opposite effect — because in drawdownThe worst peak-to-trough fall in a portfolio. he’s a seller, not a buyer. His retirement portfolio needed stability to draw from, not all-equityA unit of ownership in a company. exposure.

FAQs
Should I keep my retirement corpus all in equity for growth?
No — an all-equity corpus is dangerous in drawdown, because a crash forces you to sell at lows to fund expenses (sequence risk). Retirees typically hold a *balanced* mix: enough equity for long-term growth and inflation-beating, plus enough stable assets (debt) to fund several years of withdrawals without selling equities in a downturn. The drawdown phase needs stability you didn’t need while accumulating.
