How it works

Three steps to a real pass rate.

No spreadsheets. No guesswork. Just answers.

01
Describe your strategy

Enter your win rate, average win and average loss as a % of account, and trades per day.

02
Set your firm's rules

Pick the prop firm you're using and configure its ruleset — account size, profit target, max drawdown and max days. Toggle trailing drawdown, daily loss limit, consistency rule and minimum trading days on or off depending on what your firm enforces.

03
Run 10,000 sims

Get your pass probability, what kills the failed runs, and the break-even withdrawal once eval cost and payout odds are factored in.

Features

The math other calculators skip.

Built by traders who got tired of static-DD math and missing consistency rules.

Trailing drawdown, done right

Peak equity tracked attempt-by-attempt — not as a flat number.

Consistency rule baked in

Caps single-day P&L share. Most free tools quietly ignore it.

Break-even withdrawal

Combines eval cost and payout odds into a single, honest number.

Breach distribution

See what actually kills runs: trailing DD, daily loss, time, or target.

Live sensitivity sliders

Drag payout rate and avg withdrawal — watch funded P&L update live.

FAQ

Questions, answered.

How is pass probability calculated?+

We simulate 10,000 attempts, each played trade-by-trade against the firm's exact ruleset — drawdown, daily loss, consistency, min days, profit target.

How is this different from free calculators?+

Most free tools treat drawdown as static and skip the consistency rule. Both materially change the odds — usually downward.

Does it work for every prop firm?+

Yes. Every rule is fully configurable — account size, profit target, max drawdown (static or trailing), daily loss limit, consistency rule and minimum trading days. If a firm publishes its ruleset, you can model it.

Can I cancel?+

Yes, anytime from your dashboard. Access continues until the end of your billing period.

Stop guessing. Run the numbers.

Find out your real pass rate in under a minute — for any firm, any account size.
