Prop Firm Consistency Rule Calculator

Six-step workflow

1. Copy current values from the official account, platform, or journal.
2. Keep every unit consistent; do not mix ticks, points, pips, dollars, or percentages.
3. Enter the planning assumptions without changing them to force a preferred answer.
4. Calculate and read every output, including the warning below the headline number.
5. Verify instrument specifications and binding firm rules at the official source.
6. Save the result with its date and compare it with what actually happened.

Understand the output

Formula: Best-day ratio = largest winning day ÷ total profit. Required total = best day ÷ allowed percentage.

Worked example: A $900 best day under a 30% rule requires at least $3,000 total profit. At $2,400, another $600 is needed if no larger day occurs.

Common mistakes: using net account P&L instead of rule-defined profit, creating another oversized day, ignoring the payout window, and assuming every firm uses this formula.
