Max Drawdown Calculator

Calculate maximum drawdown percentage and the recovery gain needed to return to peak equity.
Critical for risk assessment.

Drawdown Analysis

Maximum Drawdown (MDD) is the largest peak-to-trough decline in your account equity before a new high is reached.

Drawdown % = ((Peak Equity − Trough Equity) / Peak Equity) × 100

Recovery gain needed is always larger than the drawdown:

Recovery % = ((Peak Equity / Trough Equity) − 1) × 100

Drawdown vs. recovery needed:

  • 10% drawdown → need 11.1% gain to recover
  • 20% drawdown → need 25% gain to recover
  • 30% drawdown → need 42.9% gain to recover
  • 50% drawdown → need 100% gain to recover
  • 75% drawdown → need 300% gain to recover
  • 90% drawdown → need 900% gain to recover

Professional benchmarks:

  • Most institutional traders cap MDD at 10–20%
  • Hedge funds typically trigger review at 15–25%
  • Drawdowns above 30% often indicate a broken strategy or regime change
