Prop Firm Consistency Rule Explained
- Going over a consistency rule usually doesn't fail your account. The rule limits how much of your total profit one day can be, and a big day just means you keep trading until your best day is back under the cap.
- Your real finish line is your best day divided by the percentage. A $1,500 best day under a 30% rule means $5,000 in total profit, even when the profit target says $3,000.
- A lower percentage is the tighter rule. A 20% cap needs five times your best day in total profit, while a 50% cap only needs double.
- Some firms run it on the eval, some on payout requests after you're funded, and some on both. The payout version is the one that decides when you get paid.
- Watch for rules with no number at all. If a firm can review your trading as a whole and reduce a payout or close the account, there's no percentage you can plan around.
One big day can raise the total profit you need well past the profit target on your account. Start with the calculator below to see your number, then read how the math works, where firms apply the rule and what to look for in the rules before it costs you time or a payout.

The cap shown is the firm's published funded-payout percentage. Eval-stage caps are not always published and can differ by account, so if you are still in the evaluation, check your account's rules or switch to Enter My Own Numbers.
The table below is the published caps for the futures firms we track. A number here is the firm's numeric cap and nothing more. A firm can also review payouts manually or keep discretion on top of the number, which is exactly the fine print the Where the Rule Lives section below is about. Account-by-account detail lives on each firm's review.

What the Consistency Rule Is
You catch a clean trend day, string together three winners, and hit your entire profit target before lunch. Then you check the dashboard and the firm says you cannot pass yet. Nothing broke. No rule was violated. You just ran into the consistency rule, and it wants more trading days out of you before that money counts.
A consistency rule caps how much of your total profit can come from a single day. A 30% rule means no one day is allowed to be more than 30% of everything you have made on the account. Under the cap, you pass or get paid. Over it, you keep trading until the ratio comes down.
The firm's reasoning is not hidden. One monster day proves you got one monster day. It doesn't prove the firm can hand you their capital and expect the same trader to show up next month. Firms fund repeatable trading, so they built a rule that makes one lucky swing mathematically unable to carry an account. That part is fair. The part you need to watch is how the math works, because it doesn't work the way most traders assume, and the surprise always lands on your best day.
How I Treat the Rule
I do not look at the consistency rule at all when I buy an account, because I trade small and it has never come into play for me. The only way it would is an incredible day that goes over the cap, and then all it costs is a few more trading days to even the ratio out. A consistency rule only bites the trader who swings size around, and bending rules to get around one is what a gambler does.
The Math: One Big Day Raises the Bar
Here is the piece a lot of guides skip. A big day doesn't break the consistency rule. It raises the total you now have to earn.
The rule divides your best day by your total profit. So the fix for a bad ratio is not undoing the big day, it is growing your total profit. Take a 50K eval with a $3,000 target and a 30% rule. You make $1,500 on Tuesday. Your total is $1,500, your best day is $1,500, your ratio is 100%. Way over. Even when you grind to the $3,000 target, that Tuesday is still 50% of your total. Still over.
The formula that tells you where you actually stand is one division: best day divided by the percentage. $1,500 divided by 0.30 is $5,000. That is your real finish line now. The account said $3,000, your best day said $5,000, and the bigger number wins. Your best day set the bar, and every dollar of that extra $2,000 exists only because Tuesday went well.
The Same Math on Payouts
Same math holds back payouts on funded accounts. Say your firm runs a 20% consistency check on withdrawals and your best day since the last payout is $2,000. $2,000 divided by 0.20 is $10,000. You are not requesting a payout until the account has earned $10,000 in that window, however long that takes.
So run the division after any strong day. Best day over the percentage, that is your number. Traders who know that number trade toward it calmly. Traders who do not find it out from a rejected payout, and that is the worst possible way to learn division.
One Caution: The Inputs Vary
Some firms count calendar days, some count only profitable days, some measure per eval and some per payout window. The formula holds, the definitions move. The firm's own rule page has the definitions, and our reviews carry them firm by firm.
Where the Rule Lives: Evals, Payouts, and the Fine Print
The rule gets applied in two places, and a firm can run it in one, the other, or both.
The Eval Version
The eval version holds back your pass. You can hit the target and satisfy every other rule, and the account simply doesn't convert to funded until your ratio is under the cap. This is a common version and the gentlest, since the only cost is time and the extra profit you are forced to book.
The Payout Version
The payout version holds back withdrawals on the funded account. Same division, applied to the profit window behind each payout request. This is the version that stings, because it decides when you see money, and it is the version most traders never read until a payout gets held. Living with that rule after you pass is part of the job the how to keep a funded account guide is about.
It Does Not Fail Your Account
Now the part a lot of guides leave out, and it is the opposite of what many posts about this rule imply. Across the futures firms we track, a consistency rule doesn't fail your account. Not one of them. Every firm we cover runs it as a hold. Go over the percentage and the firm doesn't close you, it makes you keep trading until the ratio comes back under the cap. A couple of them simply raise the profit target you have to hit instead. Read the firms' own words on it and they say so plainly. So the rule costs you time and it costs you patience, and that is the whole bill. It doesn't cost you the account.
The Version with No Number
What can cost you the account is the version that never prints a number. A published rule that says 30% is a rule you can plan around. Terms that instead reserve the right to review your trading as a whole are a completely different animal. They list inconsistent profit-taking or an outsized winning day among the things that can lead to a reduced payout, a closed account, or a ban. At least one firm we cover has terms like that. The threshold is not published anywhere, so you are just hoping they don't flag you or deny your payout no matter how consistent you were. You find out where it was when someone tells you.
I doubt I would buy from a firm with a rule that vague. A published number is better every time, because a rule you cannot measure is a rule the firm gets to decide later.
So when you compare firms on this rule, do not just compare percentages. Check whether there is a number at all. A firm that publishes a clear, numeric, mechanical consistency rule is telling you something good about itself, and a firm whose rule reads like it was written to be interpreted later is telling you something too. The trust sections of our reviews weigh exactly that, and it is one of the clearest tells we track about how a firm behaves on the day you finally ask for your money.
How Firms Differ on Consistency
The percentage is the headline difference, and the spread is wider than most traders expect. Across the futures firms we track, the caps generally sit between roughly 20% and 50%. The direction trips people up, too, so read this one twice: a LOWER percentage is the TIGHTER rule. A 20% cap means your best day divided by 0.20, which is five times your best day as the required total. A 50% cap only asks for double. Same rule, same wording on the sales page, and one of them makes you work five times as hard to meet it.
The bigger difference is that plenty of accounts have no consistency rule at all. Firms increasingly sell rule-light account types where the consistency check is simply absent, usually at a higher price or with tighter drawdowns paying for the freedom. For a trader whose profits genuinely arrive in bursts, those accounts are worth every dollar of the difference. We keep the ranked list of them on our prop firms with no consistency rule page, which is the answer to the which-firm question this guide deliberately doesn't chase.
Trading With the Rule Instead of Against It
Most of the time the consistency rule is a patience tax, not a wall. You do not have to trade differently to satisfy it, you have to keep showing up. But a little planning turns the tax down.
Do the Math
Know your number every day. Run the division after each session and you always know your real finish line. If your best day is creeping toward the cap, the answer is more ordinary days, not a heroic one. And do not nurse a runner into a giant day right before a payout request, because that is the exact moment the division hurts the most. Take the trade your edge gives you, just know what it does to your window.
Size Evenly
The rule is really measuring your sizing discipline in disguise. A trader risking the same amount every day almost never trips a 30% cap. The trader who doubles up on conviction days trips it constantly, and that trader is also the one the rule was built to catch, so the firm and your risk manager happen to agree here.
If you would rather have the even size handed to you than eyeballed, the position size calculator works it out from your account's drawdown and your stop distance. It keeps the answer the same boring number every day, which is exactly what this rule wants from you.
Or Buy the Account Without the Rule
And if your method honestly produces a few big days a month and quiet stretches between, stop fighting the rule and buy the account without one. That is not a workaround, that is matching the product to the trader. The no consistency rule list has the candidates, and the prop firm finder will sort your options by exactly this kind of fit. The drawdown rule on those accounts becomes the thing to study instead, and our trailing drawdown guide covers that side of the rules.
The consistency rule is not a scam and it is not harmless. It is a bill that comes due on your best day. Know the percentage, know where it applies, and run the division before the firm runs it for you.
Frequently Asked Questions
What Is the 30% Consistency Rule?
It means no single day can account for more than 30% of your total profit on the account. If your best day is $1,500, your total profit has to reach $5,000 before you can pass or get paid, because $1,500 is 30% of $5,000. The same logic applies at any percentage a firm sets, 20, 35, or 40, only the division changes.
How Do You Calculate the Consistency Rule?
Divide your best day by the firm's percentage written as a decimal. That gives the total profit you need. A $2,000 best day under a 25% rule is $2,000 divided by 0.25, so $8,000 total. To check where you stand instead, divide your best day by your current total profit, and if the result is under the firm's percentage you are compliant.
What Happens If You Break the Consistency Rule?
At the futures firms we track, nothing breaks. The rule is a hold, not a kill switch: an oversized day means you keep trading until your total profit grows enough to bring the ratio under the cap, and at some firms it simply raises the profit target instead. The cost is time, not the account. The exception to watch for is a firm that publishes no percentage at all and reserves the right to review your trading and reduce or deny a payout at its discretion. That is a real thing in this niche, and it is a reason to read the terms and conditions before you buy rather than after.
Does the Consistency Rule Apply After You Are Funded?
At many firms, yes. Some drop the rule once you pass the evaluation, but plenty keep a consistency check on funded accounts and apply it to payout requests, measuring your best day against the profit window behind each withdrawal. The funded terms and the evaluation terms are separate documents at many firms, so check both rather than assuming the eval rules carry over.
Do All Prop Firms Have a Consistency Rule?
No. It is common but far from universal, and many firms now sell specific account types with no consistency rule at all, usually at a higher price or with a tighter drawdown balancing the freedom. If your profits naturally come in bursts, those accounts exist for exactly your situation, and comparing them against the rule's real cost is worth the time.
