What Is a Drawdown in Trading?
A drawdown is the drop from a peak in your account to a later low, usually shown as a percentage. Here is how it is measured, the break-even maths, and how to keep it small. Educational, not financial advice.
A drawdown is the drop from a peak in your account (or a strategy's equity) to a later low, usually stated as a percentage. If your account falls from $10,000 to $8,000, that is a 20% drawdown. It measures how much you have given back from your best point. Educational, not financial advice.
How drawdown is measured
- Peak to trough — take your highest equity, then the lowest point reached after it.
- Stated as a percentage of the peak.
- Max drawdown is the single worst peak-to-trough fall over a period.
Why it matters: the break-even maths
Drawdowns are asymmetric — the bigger the loss, the disproportionately larger the gain needed to get back to even:
| Drawdown | Gain needed to break even |
|---|---|
| 10% | about 11% |
| 20% | 25% |
| 50% | 100% |
| 80% | 400% |
This is why keeping drawdowns small matters so much — see why a 50% loss needs a 100% gain. Our break-even calculator shows the gain required for any loss.

Drawdown in prop challenges
Firms cap it directly: a max drawdown is a hard floor for the whole account, and a daily loss limit caps a single day.
How to keep drawdowns small
Risk a small, fixed fraction per trade (the 1% rule), stop for the day at a set loss, and size every trade with a position size calculator.
Takeaway
A drawdown is how far you have fallen from your peak, as a percentage. Because break-even is asymmetric — a 50% fall needs a 100% gain — keeping drawdowns small with fixed, small risk is the whole game.
