Prop Firm CalculatorsWhat the model counts
- Sales: challenges sold × average price.
- Payouts: challenges × phase 1 pass rate × phase 2 pass rate gives the funded traders; the share of them who reach a payout, times the average payout, gives what you pay out.
- Costs: payment processing and affiliate commission as a share of sales, plus your platform's monthly and per-account fees.
It is a steady-state month: it assumes the traders being paid this month were funded from similar earlier months. The default pass rates are from the PropSim Prop Trading Index; the payout assumptions are yours.

Questions
How do prop firms make money?
Mostly from evaluation fees. Because most attempts fail, the fees from many traders fund the payouts to the few who are funded and profitable, plus the firm's costs and margin.
What pass rate should a prop firm plan for?
It depends on the firm's rules. In the PropSim Prop Trading Index for the week of 2026-10-19, 14.1% of accounts cleared phase 1 and 34% of phase 2 accounts cleared it. Test your own rules against your own data.
What does prop firm software cost?
Pricing models differ: flat monthly fees, per-account fees and revenue shares. PropSim's prop firm cost page compares published pricing with sources.
