Know your odds before you pay.
Free, no-signup calculators built on the same data discipline as the rest of PropWorld: real challenge rules for 11 firms, transparent maths, and results you can download and check.
Prop Firm Simulator & Pass Rate Calculator
Enter your win rate, risk and reward once, and a Monte Carlo simulation replays your strategy thousands of times against each firm's real rules — profit targets, trailing drawdowns, daily loss limits — to show your true odds of passing, your expected cost and your time to funded.
Open the tool →📐Kelly Criterion Calculator
Your growth-optimal risk per trade (half Kelly), sized against the drawdown buffer instead of the nominal balance — a sensible ceiling on risk for challenge accounts, with full, half and quarter Kelly side by side.
Open the tool →Educational tools only — statistical models built on the figures you enter, not predictions or financial advice. Firm rules and prices change; always confirm current terms on the firm's own site. Some outbound links are partner links, which never change the results the tools produce. See how we measure.
