Prop Firm Consistency Rule Calculator
Check whether your daily profit distribution passes before you start trading. This calculator supports both rule types used by modern prop firms:
- Legacy (Max Day %) — your best day cannot exceed X% of total profit
- Modern (Average-Based) — your daily profits must stay within a range of your average

How to Read Your Results
Your distribution is within limits. You can trade with this daily P&L pattern.
Your largest day is approaching the threshold. Reduce daily targets or spread profits across more days.
Your profit is too concentrated. You need to trade more days or cap daily profits lower.
Quick Fixes If You're Failing
Trade more days. With a $3,000 target and 30% rule over 10 days, your max per day is $900. Over 15 days, it's $1,350. More days = higher ceiling.
Cap your daily profit. Set a hard stop at 80% of your max allowed. Hit $720 when your cap is $900? Close the platform.
Front-load small wins. Start with 2-3 modest green days. This builds a distributed base that gives later days more headroom.
Switch to a firm without the rule. If your trading style naturally produces concentrated profits, compare firms without consistency rules.
Why Uneven Profits Fail
The consistency rule exists because prop firms want to fund traders who demonstrate repeatable skill, not one-time luck. Two traders can both make $3,000 — but the one who made $600/day for 5 days is considered more fundable than the one who made $2,500 on Monday and $500 the rest of the week.
The legacy model uses a simple percentage cap: best day / total profit. If you made $1,200 out of $3,000, that's 40%. With a 30% rule — fail.
The modern average-based model is stricter on outliers. It calculates your mean daily profit and flags days that deviate too far. A day that's 2.5x your average gets flagged — even if it's below the legacy percentage threshold. This catches traders who have one big day and several tiny days.
The calculator above lets you check both models simultaneously. Toggle between "Legacy" and "Modern" to see how the same numbers perform under each rule type.
