How Much Gain to Recover from a 50% Loss
Losses and gains are not symmetric — here is exactly what it takes to climb back.
At a glance
The Short Answer
A 50% loss requires a 100% gain to recover. If $10,000 falls to $5,000, doubling the remaining money is the only way back to $10,000. In general, recovering from a loss of L% takes a gain of L ÷ (100 − L) — a formula that grows faster than intuition suggests.

Recovery Gains for Common Losses
| Loss | Remaining per $10,000 | Gain Needed to Break Even |
|---|---|---|
| −10% | $9,000 | +11.1% |
| −20% | $8,000 | +25.0% |
| −30% | $7,000 | +42.9% |
| −50% | $5,000 | +100.0% |
| −60% | $4,000 | +150.0% |
Why the Math Works Against You
Percentages apply to the current balance, not the original one. After a 50% drop, every further percentage point is earned on half the money. This asymmetry is exactly what the geometric average captures: a +50% year followed by a −50% year has an arithmetic average of 0% but a geometric average of about −13.40% per year, matching the real 25% loss. Enter 50, -50 in the calculator above to see it.
The Practical Lesson
Avoiding large losses matters more than chasing large gains. A portfolio that falls 50% and then earns a strong 10% a year still needs more than seven years to break even. Limiting drawdowns — through diversification, position sizing, or a saner risk level — keeps the required recovery gains in the modest left half of the table, where ordinary market returns can do the job.
Frequently Asked Questions
Why doesn't a 50% gain undo a 50% loss?
Because the gain applies to the reduced balance. $10,000 that falls to $5,000 and then rises 50% reaches only $7,500 — still 25% below where you started.
How long does it take to recover from a 50% loss at typical returns?
At 10% a year, about 7.3 years (1.1^7.3 ≈ 2). At a steadier 7%, roughly 10 years — which is why deep drawdowns are so costly.
Does the recovery math apply to individual stocks too?
Yes. A stock down 50% must double to return to its prior price, regardless of the company or the reason for the decline.
Is a small loss really easier to recover from?
Dramatically so. A 10% loss needs only an 11.1% gain, and a 20% loss needs 25% — both achievable within a single decent year, unlike the doubling a 50% loss demands.
