How Much Do You Need to Gain to Recover From a 50% Loss in Trading?
Direct answer
Recovering from a loss
You need a 100% gain to recover from a 50% loss. The formula is required gain = 1 ÷ (1 − loss) − 1, because after a loss you are growing a smaller balance: $10,000 down 50% is $5,000, and $5,000 must double to return to $10,000. A 10% loss needs 11.1%, 20% needs 25%, 30% needs 42.9%, 70% needs 233% and 90% needs 900%. At a steady 7% a year, recovering from a 50% loss takes about 10.2 years. Real markets show it: the Nasdaq Composite fell 77.9% from March 2000 to October 2002, needed a 353% gain, and only got back to its 2000 high in April 2015, 15.1 years later, on FRED data.
- Required gain = 1 ÷ (1 − loss) − 1
- −10% → +11.1%
- −20% → +25%
- −30% → +42.9%
- −50% → +100%
- −70% → +233%
- −90% → +900%
- At 7% a year, a 50% loss takes ~10.2 years to recover
- Nasdaq 2000–02: −77.9%, back to its high only in April 2015
Losses and gains aren't symmetric. Drop 50% and gain 50%, and you're still down 25%. This page puts the arithmetic and the real-market evidence in one place.
What people on X are asking
In September 2026 a post warned that a 50% loss needs a 100% gain just to break even, adding that a 20% loss needs 25% back and a 10% loss about 11%. In October 2026 a calculator builder posted the same idea with more steps: down 30% you need +42.9%, down 70% you need +233%, calling the maths asymmetric. Both are correct; the extra questions are how long recovery takes and how often markets fall that far.
The fact-checked answer
The formula. If you lose a fraction L, you have (1 − L) left. To get back to 1 you need to multiply by 1 ÷ (1 − L), so the gain needed is 1 ÷ (1 − L) − 1. For L = 50%: 1 ÷ 0.5 − 1 = 100%.
Gain needed to recover a loss, and years at a steady return
Our calculation. Years = ln(1 ÷ (1 − loss)) ÷ ln(1 + annual return). Steady returns are an illustration, not a forecast; you can check compounding with Investor.gov's compound interest calculator. Tap a column header to sort.

Why it matters more than it looks. Small losses are cheap to recover; big ones aren't. The gain needed grows slowly up to about 20% and then explodes: going from −50% to −60% adds 50 percentage points to the required gain, and from −80% to −90% adds 500. See trailing vs static drawdown for how prop firms measure it.

Big Nasdaq Composite drawdowns and how long recovery took (FRED)
Price index only; dividends would shorten recovery somewhat. Other falls of 25–35% occurred in 1981–82, 1983–84, 1989–90 and 1998. Tap a column header to sort.

The 2000 case is the 70–80% row of the table in real life: the Nasdaq needed to rise 353% from its October 2002 low of 1,114 to regain 5,048, and it took 12.5 years from the trough. By contrast, the 2020 crash needed 43% and recovered in 3½ months. For how often smaller declines happen, see how often the Nasdaq falls 10% and what a bear market is.
Individual stocks and traders are worse. An index recovers because survivors replace losers. A single stock down 90% may never come back, and a trading account that loses 50% often does so because of oversized positions that also make recovery harder. FINRA lists the risk of losing money as part of every investment; Investor.gov explains diversification as a way to reduce the risk of large losses from any one holding.
UXS decision diagram
How do I stop a loss from becoming a 50% drawdown?
Text version of the diagram
- Do you risk more than 2% of the account per trade? If yes: Cut it: ten losses at 10% each leave 35% of the account
- Do you have a maximum drawdown at which you stop and review? If no: Set one, such as 10–15%, before it happens
- Is one position or theme more than a quarter of your money? If yes: Diversify: one bad bet shouldn't need a double to repair
- After a big loss, are you increasing size to win it back? If yes: Stop; that is revenge trading and deepens the hole
- Otherwise: Small, capped losses keep the required recovery gain small

Practical maths for traders. At 1% risk per trade, ten losses in a row cost about 9.6%, needing 10.6% to recover. At 10% risk per trade, the same streak costs 65%, needing 187%. See how much to risk per trade, how many losses in a row are normal and what revenge trading is. Leverage multiplies the problem; see how leverage works in crypto futures.
Decision helper
| Your drawdown | Gain to recover | Priority |
|---|---|---|
| Under 10% | Under 11% | Normal; keep the process |
| 10–20% | 11–25% | Review size and setups |
| 20–40% | 25–67% | Cut size sharply |
| Over 40% | Over 67% | Stop and rebuild the plan |
Common mistakes
- Thinking a 50% gain repairs a 50% loss.
- Doubling size to "win it back".
- Assuming a single stock will recover like an index.
- Ignoring how long recovery takes.
