How is the consistency rule calculated?

Most firms divide your best single day's profit by your total profit for the period. Some divide by the profit target instead. The calculator above does both.

Does a losing day help the consistency rule?

No. Losing days lower total profit, which makes your best day a bigger share. Only more profitable days, or a smaller best day, lower the share.

Which prop firms have a consistency rule?

In our 5 November 2026 read of 16 firms' rule pages, 7 published one; several apply it only to funded-account payouts. Check your firm's current page.

What happens if I break it?

Usually the account is not closed; the payout waits until enough extra profit brings the best day under the cap. Some firms treat it differently - read the payout section of your firm's rules.

Prop firm consistency rule calculator

A consistency rule says your best day can be at most a set share of your total profit - often 30%, 40% or 50%. The check is best day divided by total profit. If your best day is $1,500 and total profit is $4,000, your best day is 37.5%: that breaks a 30% rule, and you would need $5,000 total profit ($1,500 / 0.30) with no bigger day to pass. Paste your days below to check yours.
