Try an editable example of the best-day profit concentration test. See exactly how a hypothetical percentage cap changes as total eligible profit grows, without assuming every prop firm uses the same definition.
Enter the largest profitable day, the eligible profit total and an example maximum single-day share. The figures below are not a named firm's actual rule.
Largest day's share: 50.00% of the entered eligible profit total.
Meets this hypothetical cap: No.
Extra eligible profit needed if the largest day stays unchanged: US$600.00.
Method: largest positive day ÷ eligible profit total × 100. When above the cap, extra profit = (largest day ÷ (cap ÷ 100)) − current eligible profit. This model assumes additional profit does not increase the largest qualifying day and ignores fees, withdrawals and provider-specific definitions.
Real programmes can use net profit, gross profitable days, funded-stage-only history or different consistency formulas. Always use the provider's exact official rule before buying or requesting a payout.
Illustration only: if the largest positive day is $1,200 and eligible profit totals $2,400, that day accounts for 50%. In a hypothetical programme requiring no day to exceed 40%, the total would need to reach $3,000 without the best day increasing. That implies another $600 of eligible profit under this simplified formula.
Some rules measure profit since the last withdrawal, some from account inception and others only for a funded stage. A net-profit total and the sum of positive days are not interchangeable. Read the definition before using any numerical result.
The formula reports concentration, not trading ability or the probability of an actual payout. Later profits can change both the numerator and denominator if a new largest day occurs.
Minimum trading days, payout caps, restricted sessions, account status and any loss rules can still prevent a withdrawal even if the example consistency percentage is within the limit.
