Rule-accurate calculators for every stage of prop trading — challenge selection, risk mechanics, payout eligibility, and true economics. Built on a maintained firm-rules database, not copied from marketing pages.
Simulate any strategy against static, EOD trailing, intraday trailing, and dynamic drawdown rules. The #1 mechanic that eliminates funded traders — now visible.
Apex 50% (v4.0, legacy 30%), Topstep 40%/50%, MFFU 50%/40%, FTMO 50% positive-days, FundedNext 40%. Shows required total profit, deficit, and max allowable next day.
Compare up to 4 firms across 18 dimensions: drawdown type, consistency rule, profit split, fees, trading freedoms. Shareable permalinks.
Challenge fee + resets + activation + platform fees + monthly data — minus first-payout refunds. The $29 eval that becomes $487 before funding.
Combines pass probability, profit expectation, blowup risk, and true cost into a single EV figure. Shows required pass rate to break even.
Feeds from True Cost. Shows months-to-break-even at P10/P50/P90, with cumulative cost vs. payout curves and reset-blowup scenarios.
Monte Carlo simulation across 10,000 paths. Enter win rate, R:R, risk per trade — get pass probability, median days to pass, and fractional-Kelly suggestion.
Waterfall from gross → consistency gate → safety buffer → payout cap → tiered split → refund. Handles Apex piecewise, Topstep Express cap, first-payout refund.
Models scaling events across 12/24 months. FTMO +25% linear per 4-month cycle, Topstep Live Risk Expansion, Apex multi-account merge economics.
Calculates max lots/contracts that respect daily loss, trailing DD buffer, consistency ceiling, and instrument tick value simultaneously. Labels the binding constraint.
Gantt-style timeline to next eligible payout. FTMO 14-day cycles, Apex 1–5 & 15–20 windows, Topstep 5 winning days ≥$200, MFFU $11,250 cap per cycle.
Compares reset cost to rebuy at current sale price. Sale-calendar aware (Black Friday, Cyber Monday, New Year, Memorial Day, Labor Day). Break-even %.
Prop firm comparison sites exist to sell affiliate clicks. They compare headline numbers — account size, profit split, "max drawdown" — and call it a day. Those numbers are spec-sheet theatre. Whether you pass a challenge, whether you get paid, and whether the economics work out are determined by mechanics the headline numbers don't describe.
Industry data suggests roughly 1–2% of prop firm purchasers ever receive a payout.[1] Pass rates of 7–14% combined with 20–45% payout rates compound that way.[2] The difference between the 1–2% and everyone else isn't luck or edge — it's understanding which firm's mechanics are compatible with the strategy they already have, and sizing the economics correctly before buying.
Every tool here does one job well. The drawdown visualizer shows survival under trailing rules. The consistency calculator shows payout eligibility. The true cost calculator shows all-in spend before funding. The comparison tool narrows the firm field on the mechanics that matter. Tools compose — outputs from one feed inputs to the next.
Data is verified and versioned. Prop firm rules change every 3–6 months — Apex launched v4.0 on March 1, 2026, banning overnight holds and restructuring the entire product line[3]; Topstep moved new traders to a straight 90/10 profit split on January 12, 2026[4]. Every tool shows a last-verified date. The firm database is the asset; the calculators are views on top of it.
Each calculator sits at a specific point in the funnel — from "which firm should I pick" through "will I survive the challenge" through "when will I actually get paid". Use them in the order you encounter the decisions.
