01
Measure concentration
Best-day profit ÷ total profit gives the current best-day share.
Payout discipline
Turn the best-day rule into a clear process constraint.
Calculate your best-day share, check a prop-firm consistency rule, and see the profit buffer needed before a payout request. No payout prediction—just the rule math and the part of the process you can control.

Payout-eligibility read
Your best day is too concentrated for a 30% rule. The process constraint is $166.67 more total profit without creating a new larger best day.
Firm definitions, minimum trading days, balance cushions, and payout windows vary. Confirm the current rules before submitting a request.
The math behind the limit
Consistency is concentration, not a grade on profitability.
A 30% rule means the best day can account for no more than 30% of total profit in the period. The calculator divides the best day by total profit, then shows the minimum total needed to bring that share inside the limit.
02
Find the constraint
Best-day profit ÷ rule percentage gives the minimum qualifying total.
03
Protect the process
If a buffer remains, avoid chasing it. Follow the plan and let qualifying profit accumulate without forcing a new outlier day.
From calculator to record
The rule is easy to calculate. The discipline behind it deserves a daily record.
TraderGrade tracks preparation, risk, execution, and review—the decisions that make a payout process repeatable without grading the P&L outcome.
