The loss recovery calculator solves a math problem most traders get wrong: percentage losses and gains are not symmetric. A 30% loss requires a 42.9% gain to break even — not 30% — because the gain is applied to a smaller base. The calculator above converts any drawdown into the exact recovery percentage required, then adds a time dimension by estimating how many trades and weeks recovery realistically takes at your win rate, R:R, and trading pace.
How to Use
| Input | What to Enter | Example |
|---|---|---|
| Account Size | Your balance before the loss occurred | $25,000 |
| Loss Amount | Percentage of the account that was lost | 30% |
| Risk Per Trade | Percentage risked per trade during recovery | 1% |
| Risk-Reward Ratio | Average reward relative to your risk | 2 (for 2:1) |
| Win Rate | Your historical win percentage | 50% |
| Trades Per Week | Your typical weekly trade count | 5 |
The calculator outputs the required recovery percentage, the dollar amount to recover, and a trade-count and week estimate. The week estimate assumes consistent expectancy — it is an average, not a guarantee.
Formula Explained
Recovery % = Loss% / (1 - Loss%) × 100
Expectancy per Trade = (Win Rate × Avg Win $) - (Loss Rate × Avg Loss $)
Trades to Break Even = Dollar Loss / Expectancy per Trade
Weeks to Break Even = Trades to Break Even / Trades per Week
Recovery percentage: Because a 30% loss reduces the account from $25,000 to $17,500, any subsequent gain is applied to $17,500, not $25,000. Getting from $17,500 back to $25,000 is a $7,500 gain on a $17,500 base — 42.9%, not 30%. This asymmetry compounds severely at larger losses: 50% down requires 100% to recover; 75% down requires 300%.
Expectancy per trade: With a 2:1 R:R, a $175 risk produces a $350 win or $175 loss. At 50% win rate: (0.5 × $350) − (0.5 × $175) = $87.50 per trade. This is the average profit per trade over a large sample and is the engine of recovery.
Trade count and time: Dividing the dollar loss by expectancy gives the number of trades required at that average. At 40% win rate and 1.5:1 R:R, expectancy drops to 0.1R per trade — recovery becomes very slow. At 55% win rate and 2:1 R:R, expectancy is 0.65R — roughly 6.5× faster than the 40% / 1.5:1 scenario.
Example Calculations
Scenario 1: SPY Stop-Loss Ignored During Earnings
- Account: $25,000 → drops to $17,500 (30% loss)
- Recovery needed: $7,500 on a $17,500 base = 42.9%
- Risk per trade: 1% = $175 | Win: $350, Loss: $175
- Expectancy: (0.5 × $350) − (0.5 × $175) = $87.50/trade
- Trades to recover: $7,500 / $87.50 = 86 trades
- Time: 86 trades / 5 per week = ~17 weeks
If this trader bumps risk to 2% ($350/trade) hoping to recover faster, one 5-loss streak costs $1,750 instead of $875 — pushing the recovery target from $7,500 to $9,250 and adding another 24 trades to the timeline.
Scenario 2: Funded Account Near Drawdown Limit
- Account: $50,000 funded (FTMO-style, 10% max drawdown)
- Loss: 10% = $5,000 | Remaining: $45,000
- Recovery needed: $5,000 / $45,000 = 11.1%
- Risk per trade: 1% = $450 | Win: $900, Loss: $450
- Expectancy: (0.5 × $900) − (0.5 × $450) = $225/trade
- Trades to recover: $5,000 / $225 = 23 trades
- Time: 23 trades / 3 per week = ~8 weeks
For prop firm traders, The5ers imposes a 6% max drawdown, meaning a trader near that limit must recover just 6.4% — manageable but requiring disciplined sizing since any further loss may breach the account.
Scenario 3: Small Account, 25% Drawdown
- Account: $10,000 → drops to $7,500 (25% loss)
- Recovery needed: $2,500 / $7,500 = 33.3%
- Risk per trade: 1% = $75 | Win: $150, Loss: $75
- Expectancy: (0.5 × $150) − (0.5 × $75) = $37.50/trade
- Trades to recover: $2,500 / $37.50 = 67 trades
- Time: 67 trades / 4 per week = ~17 weeks
When to Use the Loss Recovery Calculator
- After blowing a stop-loss: Calculate the real recovery requirement before your next trade. The number is almost always larger than your intuition suggests.
- After a losing streak: A 5-trade losing streak at 2% risk removes 10% of the account and requires an 11.1% gain just to return to the starting level.
- Before adjusting position size: Traders who increase size after losses (revenge trading) statistically deepen their drawdown. Barber and Odean (2000) documented that overtrading after losses is a primary driver of retail underperformance, costing individual investors roughly 1.5% annually.
- Prop firm drawdown management: With hard limits at 6-12% depending on the firm, knowing the exact recovery math after each loss is essential to staying in the account.
- Setting a realistic timeline: Recovery is not a weekend project. A 30% drawdown at realistic expectancy takes 3-4 months. Knowing this upfront prevents impulsive decisions driven by impatience.

Frequently Asked Questions
How do you calculate the percentage gain needed to recover a loss?
Use Recovery % = Loss% / (1 - Loss%) × 100. A 20% loss requires 25%; a 50% loss requires 100%; a 75% loss requires 300%. The recovery percentage is always larger than the original loss percentage because gains are applied to a smaller account base.
Why does a 50% loss require a 100% gain to break even?
After a 50% loss, the account is at half its original value. A 100% gain on that reduced balance returns the account to its starting point. Because the denominator changes with every gain or loss, the math is permanently asymmetric — losses always hurt more than equivalent-sized gains help.
How long does it take to recover from a 30% trading loss?
At a 2:1 R:R, 50% win rate, 1% risk per trade, and 5 trades per week, recovery from a 30% loss takes approximately 86 trades — about 17 weeks. At a less favorable 1.5:1 R:R and 45% win rate, expectancy falls to 0.1R per trade and recovery can stretch to a year or more.
What is the loss recovery formula for prop firm traders?
The formula is the same: Recovery % = Loss% / (1 - Loss%) × 100. A trader who hits FTMO’s 10% max drawdown must generate 11.1% on the remaining balance. On a $100,000 account, that is $10,000 in gains on a $90,000 base — roughly 23 trades at 2:1 R:R and 50% win rate risking 1% per trade.
Should you increase position size to recover trading losses faster?
No. Increasing size after a loss raises the cost of each subsequent losing trade. Five consecutive losses at 2% risk removes 10% of the account; the same streak at 1% removes 5%. Larger size during recovery often deepens the drawdown rather than shortening it, and for prop firm accounts, it can trigger disqualification before recovery is complete.
