Prop Firm Drawdown Calculator

Max total loss = account size × the firm's max-drawdown %. Max daily loss = account size × the firm's daily-loss %. We use each firm's published rule, so a $100K account at a 10% max drawdown gives a $10,000 max loss.

If you risk a fixed % of the account per trade, it's how many consecutive losers reach the daily-loss limit. Risk 1% on a $100K account ($1,000/trade) against a 5% daily limit ($5,000) = 5 losing trades.

They come from each firm's decoded rulebook (their Terms of Service). Rules change often — always verify against the firm's current terms before trading.
