Prop Firm Survival Calculator

The whole journey in one screen: pass the evaluation, survive the funded account, then actually get paid — joint probability and cap-aware take-home, on your firm's verified rules. Copy a link to share any scenario.

Buy-in → first payout

Set a daily loss limit, pick a firm to use its verified rule, or tick “No daily limit.” Leaving it blank would assume the most forgiving outcome, which we don't do (D25).

Probability you reach a first payout

Model assumptions

  • Three stages chained: pass the evaluation, then survive a payout window funded, then take the payout. The journey probability is P(pass) × P(survive) — independent stages.
  • Fixed-fractional risk on the starting balance (no compounding), independent trades, constant win rate and R:R. Real P&L has tails this does not.
  • Expected window P&L is win-rate expectancy × trades — a long-run average, not a guaranteed month. A losing edge shows no payout because there is none to project.
  • The payout cap is applied only when it parses to a clean monthly figure; conditional, tiered, or per-payout caps surface as the firm’s own wording, not a number.
