How the consistency rule works

Prop firms cap how much of your profit can come from one trading day. The intent is simple: they fund process, not one lucky session. The mechanics are just as simple - your best day divided by a denominator your firm chooses, compared against a percentage. What trips traders up is that the details differ by firm: the percentage, the denominator, and the stage where the rule is checked.

consistency % = best day ÷ denominator × 100
profit to dilute = best day ÷ limit − current total

The second line is the one that matters when you are over. You cannot shrink a day that already happened - you can only make it a smaller share of a bigger total. A $2,600 best day under a 50% rule needs $5,200 of total profit before it stops being the problem; at $4,000 total you are $1,200 short, and that number - not the percentage - is your actual to-do list.

Every firm's rule, verified

These presets come from each firm's official rules pages and help centers, re-verified July 2026. Firms change terms often - when the numbers move, the presets move with them.

Worked example: a funded account payout

You are funded under a 50% rule with $4,000 of profit, and your best day was $2,600 - that is 65%, so the payout request stays unavailable. The dilution math says you need total profit of $5,200, so $1,200 more. And because a new giant day just moves the problem, the calculator also shows the biggest day you can add without becoming inconsistent again: with $4,000 banked under a 50% rule, that is $4,000 - anything larger becomes the new best day at over half the new total.

Worked example: Topstep's different denominator

Inside the Trading Combine the comparison is not against your profit - it is against the profit target. On a 50k Combine with a $3,000 target, your best day must stay at or below $1,500 regardless of what your total is. Go over - say a $2,000 day - and the objective effectively raises your bar to $4,000 of profit before you can pass. Different shape entirely, which is why picking the right preset matters more than remembering a percentage.

Sizing is the real fix

A consistency problem is usually a sizing problem wearing a disguise: the oversized day almost always came from oversized risk. If your normal day risks 1% and your best day came from risking 4%, the rule is telling you what your risk plan already knew. The position size calculator keeps the day-to-day honest, and the risk/reward calculator tells you whether the trade was worth taking at that size in the first place.

FAQ

Do I need a TradeDNA account to use this calculator?
No. Every tool here is standalone and free - no signup, no usage limits. A TradeDNA account is for what comes after the math: your real best day and total profit computed from actual fills, checked against your firm's rule on every trade.
What is a prop firm consistency rule?
A cap on how much of your profit can come from a single trading day. If your best day is too large a share of the total, the firm delays your payout on a funded account, or your pass in an evaluation, until more profit dilutes it. At every firm in this calculator's presets it is a soft rule - being over the line never fails the account by itself.
How is the consistency percentage calculated?
Most firms divide your best single day by your total net profit. If your best day is $2,600 and your total profit is $4,000, you are at 65% - over a 50% rule. Two firms use a different denominator: FTMO's 1-Step divides by profit from positive days only, and Topstep's Combine compares your best day against the profit target itself. The presets apply each firm's own published formula.
How do I get back under the consistency limit?
You cannot shrink a past day - you dilute it. Divide your best day by the limit and subtract your current total: that is the additional profit you need. A $2,600 best day under a 50% rule needs $5,200 of total profit, so at $4,000 you need $1,200 more. The calculator does this for every preset automatically.
Does breaking the consistency rule fail my prop firm account?
At every firm in the presets, no. Funded accounts have the payout held until the percentage falls back under the limit, and evaluations wait to pass. Apex states it directly: being above 50% does not fail your account - the payout option is simply unavailable until you are back under.
What consistency rule does my firm use?
As of July 2026, from each firm's official pages: Apex 50% on current funded accounts (30% on Legacy), Topstep 40% on the Express Funded consistency path plus a 50%-of-target objective inside the Combine, MyFundedFutures 50% during Rapid and Pro evaluations, TakeProfitTrader 50% in the Test, Tradeify 40% on Select evaluations and 35% on Growth funded accounts, FTMO 1-Step 50% Best Day, TopOne 25% funded, Lucid 40% funded, fewpips 40% funded. Firms change terms often - the presets carry the date we last verified each one.
Why is my biggest day a problem? Isn't more profit better?
Firms pay for repeatable process, not one lucky session. A single day carrying most of the profit looks like variance they will end up refunding. Spreading profit across days is what the rule buys - and it is also just what durable trading looks like.
