Prop trader calculators
The calculators that answer the questions this analysis keeps raising — what an evaluation really costs, how much room a drawdown rule leaves, and what a profit split pays. They are maintained on Prop Firm Pal, the firm-data site in this network, rather than duplicated here.
We used to run our own copies of four of these. Keeping one maintained version of a calculator is better for the person using it than keeping two that can drift apart, so they now live in one place.
Challenge ROI and break-even calculator
How many payouts it takes to clear the evaluation fee, and the 6- and 12-month net projection.
Position size calculator
Lot size from account balance, risk percentage and stop distance, plus how many losing trades the daily limit allows.
Drawdown calculator
Remaining buffer on both static and trailing accounts — the distinction that decides most failed evaluations.
Profit split calculator
What a payout actually pays after the split, and how many of them clear the challenge fee.
Risk of ruin calculator
The probability of hitting the drawdown limit before the profit target, over 1,000 simulations.
Monte Carlo simulator
Five hundred runs of a strategy against a challenge rule set, for a pass probability rather than a guess.
Challenge pass rate calculator
Expected pass probability, days to complete and the longest losing streak the rules survive.
Consistency rule calculator
Whether the best day is too large a share of total profit — a common reason a passing account is denied.
Account growth calculator
Month-by-month funded account growth with compounding and payouts taken out.
Pip value calculator
The cash value of a pip for any pair and lot size.
Still here
Breakeven win rate calculator
The win rate a strategy needs to break even at a given reward-to-risk ratio. No equivalent exists on Prop Firm Pal, so this one stays here.
The full firm dataset behind these numbers — pricing, rule sets and payout terms compared on like-for-like terms — is at Prop Firm Pal. Our own analysis of how those rules behave is in the archive.
