Uses net profit (winning days minus losing days), the way most firms measure it. Some firms (E8) require the best day to be strictly below the limit, and some count only the current payout cycle. Always check your firm's exact wording.

How to use the consistency rule calculator

Pick your firm and plan from the list, or type the limit yourself (for example 40 for a 40% rule).
Enter your results. Use Day by day to type each day's profit or loss (losses as negative numbers), or Best day + total if you already know both numbers.
Read the result. The calculator shows your best day's share of total profit, the biggest day you can still have, and how much more profit you need before you can pass or request a payout.

What is a consistency rule?

A consistency rule caps how much of your total profit can come from a single trading day. With a 40% rule and $3,000 total profit, no one day can be more than $1,200. Firms use it to stop traders passing a challenge with one lucky, oversized trade. Read our full guide to the prop firm consistency rule for how each firm applies it.

The formula is simple: best day profit ÷ total net profit × 100 = your consistency %. If that number is above the firm's limit, you need more profit spread over other days. The profit you need is best day ÷ limit.

Worked example

You trade a plan with a 40% rule. Your days were +$600, −$200, +$900, +$450 and $0. Total net profit is $1,750, and your best day is $900, which is 51.4% of profit. That breaks the rule. To bring $900 down to 40%, you need $900 ÷ 0.40 = $2,250 in total, so $500 more profit, with no single day above $900.

Tips to stay inside the rule

Set a daily profit cap. Before you trade, work out the biggest day allowed (the calculator's "max allowed best day") and stop for the day when you reach it.
Keep position size steady. Big days usually come from big size. Same risk per trade every day keeps your days similar.
Don't stop at the target. If one big day pushed you over the limit, a few small green days fix it. You don't need another big day.
Check when the rule applies. Some firms check it only at payout, some only in the challenge, and some on every cycle.

Frequently Asked Questions

How is the consistency rule calculated?

Divide your best single day profit by your total net profit and multiply by 100. If the result is above the firm's limit (for example 40%), you break the rule until you make more profit on other days.

Do losing days count in the consistency rule?

At most firms, yes. The rule uses total net profit, so losing days reduce your total and make your best day a bigger share. That is why the calculator subtracts losing days.

How much profit do I need to fix a consistency breach?

Divide your best day by the limit. With a $900 best day and a 40% rule you need $2,250 total profit. The calculator shows the exact amount still to make.

Which prop firms have no consistency rule?

Several plans have none at certain stages, for example E8 Signature in the evaluation, Maven Standard, and Blue Guardian Futures Reserve and Express once funded. Rules change, so check the firm page before you buy.

Is the consistency rule the same in the challenge and funded stage?

Not always. Some firms apply it only during the challenge, others only once you are funded or at payout, and some use a different limit in each stage. The table above lists the stage for each plan.
