How it works
Drawdown pain follows an asymmetry investors consistently underestimate: percentages DOWN and UP are not symmetric, because each loss shrinks the base the rebound must multiply. Fall 35% and you need a 53.8% gain merely to break even; fall 50% and the demand doubles to 100%. This sizer converts abstract depths into household consequences — dollars deleted from YOUR balance, the exact rebound percentage owed, and recovery timelines under a steady assumed return — then adds the detail most calculators skip: withdrawals. A retiree drawing $20,000 a year through the hole extends healing dramatically and can even make recovery impossible at modest returns, since selling low compounds the original wound. The depth ladder table lays out −10% through −60% side by side so the nonlinearity registers viscerally: halving a 60% loss to 30% cuts the required rebound from 150% to under 43%. Broad indexes have repeatedly visited 30–50% territory historically, so treat these as rehearsal numbers for weather you will likely encounter, sized against the deepest loss your behavior could actually endure without capitulating at the bottom.
Formula
Loss = value × depth% | Gain to even = depth ÷ (100 − depth) × 100% | Recovery yrs = ln(value ÷ post-drop) ÷ ln(1 + r)
Tips
- Pre-commit to a depth you can survive behaviorally — the ladder makes costs explicit.
- Halving depth cuts the required rebound by more than half; position sizing pays twice.
- Retirees should run scenarios WITH withdrawals included — that is the real stress.
- Diversifiers reduce peak-to-trough depth even when they dull rallies too.
- Never judge a fund by returns alone — ask what its worst historical drawdown felt like.
Frequently asked questions
- How much gain is needed to recover from a 40% loss?
- Exactly 66.7% — the surviving 60% base must grow by two-thirds to restore the original dollar amount. The formula divides depth by what remains: 40 ÷ 60. Deeper holes escalate brutally: a 50% loss needs 100%, and a 60% loss demands 150% just to break even.
- Why do losses hurt more than equivalent gains help?
- Two ways. Mathematically, percentages shrink the base, so a −50% demands +100% while +50% only requires −33% to erase. Behaviorally, loss aversion makes the same dollar loss feel roughly twice as intense — which is why sizing positions to tolerable drawdowns prevents panic-selling.
- How long does the stock market take to recover from a crash?
- History offers ranges, not rules: severe bear markets have taken roughly two to five years for indexes to reclaim highs in many cycles, while the 2000-era peak took years longer. With dividends reinvested and steady buying, recoveries typically shortened considerably — but 'typically' is not a promise.
- Can a retiree recover from a big early drawdown?
- It gets dramatically harder because withdrawals drain the shrunken base. On the defaults, a 35% hole with $20,000 annual drawings at 8% pushes recovery far beyond the six-ish untouched years — sometimes indefinitely. Cash reserves covering early spending are the standard defense.
- How do I limit maximum drawdown in my portfolio?
- Through allocation: smaller equity weight, quality bonds, some diversifiers, and rebalancing discipline. As a historical illustration, 2008 saw broad stock indexes fall past 50% while balanced mixes fell closer to 20–30%. Every dampener trades away upside — choose the deepest loss you would genuinely sit through.
