# 📉 Maximum Drawdown Calculator
Calculate the largest peak-to-trough decline. If you can't stomach your max drawdown, you'll abandon the strategy at the worst time.

**Answer Capsule:** Drawdown measures the peak-to-trough decline in your account. A 20% drawdown requires a 25% gain to recover. Maximum drawdown is the single most important metric for evaluating any trading strategy.

Starting Balance ($)
Equity Values (one per line)
10000
10500
10200
9800
10300
10800

Maximum Drawdown-2.0%Peak: $10,500 → Trough: $9,800 → Recovery: $10,500
💡 Rule of thumb: If max drawdown exceeds 20%, halve your position size until it drops below 15%.

## How Drawdown Is Calculated

**Formula:** Drawdown % = (Peak Value − Current Value) ÷ Peak Value × 100

**Example:** Account peaks at $15,000, drops to $12,000:

Drawdown = ($15,000 − $12,000) ÷ $15,000 = 20%
**Critical rule:** A 50% drawdown requires a 100% gain to recover. A 20% drawdown requires only a 25% gain. This asymmetry is why professional traders cap drawdowns at 20% and stop trading if breached.
