Trading losses are not symmetric. A 25% drawdown does not require a 25% gain to recover — it requires 33.3%. A 50% drawdown requires 100%. The drawdown recovery calculator quantifies this asymmetry instantly: enter a starting balance and drawdown percentage, and the tool returns the exact gain needed to return to your equity peak, plus a time estimate based on your average monthly return.
How to Use
| Input | What to Enter | Example |
|---|---|---|
| Starting Balance | Your account value at its equity peak | $20,000 |
| Drawdown Amount | The percentage decline from peak to current | 21.6% |
| Monthly Return Rate | Your average monthly gain (optional) | 2% |
The output shows your remaining balance, the required recovery gain, and — when a monthly return rate is provided — how many months of consistent performance it will take to return to peak with no net account growth during the recovery period.
Formula Explained
Required Gain = (1 / (1 - Drawdown%)) - 1
The formula works because percentage gains and losses are calculated on different bases. After a 25% loss, the remaining 75% of the account must grow by 33.3% to return to 100% of the original value. The denominator shrinks as the drawdown grows, which is why the curve accelerates:
| Drawdown | Remaining | Required Gain |
|---|---|---|
| 5% | 95% | 5.3% |
| 10% | 90% | 11.1% |
| 20% | 80% | 25.0% |
| 25% | 75% | 33.3% |
| 33% | 67% | 49.3% |
| 50% | 50% | 100.0% |
| 75% | 25% | 300.0% |
The practical implication is that keeping maximum drawdown below 25% is not a stylistic preference — it is the inflection point where recovery remains arithmetically realistic. Beyond 33%, the required gain begins to exceed what most retail strategies can achieve in a reasonable timeframe.
Consecutive losses compound rather than add. Ten trades each losing 2% of account equity produce an 18.3% total drawdown (not 20%), requiring a 22.4% gain to recover. At 1% risk per trade across a 10-trade losing streak, the drawdown reaches only 9.6%, requiring just a 10.6% gain — a threshold most strategies can clear within weeks.
Example Calculations
Scenario 1: Conservative Funded Account
- Account: $50,000
- Drawdown: 10%
- Remaining: $45,000
- Required gain: 11.1%
This falls within the FTMO 10% maximum drawdown rule. A trader generating 2% monthly returns could recover in roughly 5.3 months without changing any behavior.
Scenario 2: Eight Consecutive Losing Trades
- Account: $20,000
- Risk per trade: 3% ($600)
- Trades: 8 losses
- Remaining: $20,000 × 0.97^8 = $15,675
- Drawdown: 21.6%
- Required gain: 27.6%
At 3% risk and a 1:2 risk/reward ratio, each winner returns 6%. Recovering 27.6% through 6% wins requires roughly 4.6 net winning trades’ worth of gains — achievable, but only if position size stays constant. If the trader instead raises risk to 5% per trade to recover faster and encounters 5 more losses, the account drops to $15,675 × 0.95^5 = $12,131 — a 39.4% total drawdown requiring a 65% gain to recover.
Scenario 3: Moderate Drawdown on a Smaller Account
- Account: $25,000
- Drawdown: 25%
- Remaining: $18,750
- Required gain: 33.3%
- Recovery time at 2% monthly: approximately 14.5 months
This scenario illustrates why prop firms treat a 25% drawdown as functionally disqualifying even when not explicitly prohibited: at realistic return rates, recovery consumes over a year of gains.
When to Use the Drawdown Recovery Calculator
- Before increasing position size after losses: Calculate exactly how much deeper a larger loss will push the required recovery gain before adding size
- After a losing streak: Replace the emotional estimate (“I’m down about 20%”) with the precise required gain figure, then compare it to your historical monthly average
- During drawdown rule-setting: Determine your personal maximum drawdown tolerance based on how long you are willing to spend in recovery at your average return rate
- When evaluating prop firm rules: Model a 10% drawdown against a 5% maximum daily drawdown rule to understand how quickly a bad day can end a funded account challenge
- For position size calculator calibration: Work backwards from your maximum acceptable drawdown to the maximum risk-per-trade that keeps a 10-trade losing streak inside that limit

Frequently Asked Questions
How do you calculate the gain needed to recover from a drawdown?
Apply the formula Required Gain = (1 / (1 - Drawdown%)) - 1. For a 20% drawdown: 1 divided by 0.80, minus 1, equals 25%. The required gain always exceeds the original loss because the gain is calculated from the smaller post-loss balance.
Why does a 50% loss require a 100% gain to recover?
After a 50% loss, the account holds half its original value. Doubling that remaining balance — a 100% gain on the current amount — returns it to the starting level. This is not a paradox but a mathematical consequence of applying percentages to a shrinking base.
How long does it take to recover from a 25% drawdown?
A 25% drawdown requires a 33.3% gain. At an average monthly return of 2%, reaching that gain takes approximately 14.5 months: (1.02)^n = 1.333 solves to n ≈ 14.5. During that entire period, the account produces no net growth — all gains go toward recovery.
What is the maximum drawdown allowed in prop firm challenges?
FTMO’s standard challenge sets a 10% total account drawdown limit and a 5% maximum daily loss. These thresholds reflect the asymmetric recovery math: a 10% drawdown requires only an 11.1% gain to recover, which a profitable strategy can realistically achieve. Limits beyond 20% would require gains that most traders cannot sustain reliably.
How does revenge trading make drawdown recovery harder?
Increasing position size after losses raises the probability of a deeper drawdown on the next series of trades. If a trader doubles their size after reaching a 50% drawdown, a further 50% loss on the enlarged position produces a 75% total drawdown — requiring a 300% gain to recover rather than 100%. Revenge trading does not accelerate recovery; it compounds the mathematical hole.
