Prop firm consistency rule calculator
A consistency rule caps how much of your profit can come from one day. Split your target across days and see whether your biggest day clears the cap — and the fewest profitable days that cap allows you.

Pick the rule set closest to your account, or type your own numbers. MAV splits the target into days and checks the biggest day against the cap.

Profit target $3,000 · best-day cap 30% — the figure MAV’s simulator applies. Programs and stages differ; confirm yours with the firm.
Educational planning math on the numbers shown — not financial advice, and not a prediction that any plan passes. Prop-firm terms change often and vary by program, plan and stage; confirm your account’s current consistency rule with your firm before you trade it.
How a consistency rule actually works
Most futures prop firms measure consistency the same way: your best single day divided by your total profit, compared against a cap. A $900 day inside $3,000 of profit is 30%. Nothing about the trade itself matters — only its share of the total.
That makes the rule quietly directional: it is a cap on your best day, but it is also a floor on your number of green days. Divide 100 by the cap and round up, and you have the fewest even profitable days the rule can be satisfied in. A 30% cap cannot be cleared in three even days, no matter how good the trading is. Traders usually discover that at the payout request, not at the start.
The way out is boring and it works: plan the target as a per-day number before you start, and treat a monster day as something to balance with more ordinary days rather than as progress you can bank. That is the whole job of the calculator above.
Reading the four numbers
- Per day — The target divided by the days you plan to spread it across — your pace.
- Best-day share — What each of those even days is worth as a percentage of the total. This is the number your firm compares to the cap.
- Total that day needs — If one day really is that size, this is how much total profit it takes for that day to sit inside the cap. Above your target, it means the day was too big for the plan.
- Min days at your cap — 100 ÷ your cap, rounded up — the fewest even profitable days the rule permits. Your firm may also require a minimum number of trading days on top of this.
The caps MAV models
These are the best-day caps built into MAV’s own rule sets — the same figures the app applies when it tracks an account. They are approximations for planning, not contractual values, and where MAV models no cap we say so instead of guessing one.
| Rule set | Best-day cap MAV models |

Firm terms change often and differ by program and by stage — an evaluation cap and a funded-payout cap are frequently different numbers, and several programs have none at all. Confirm your account’s current rule with your firm; where your rule is tighter than the figure above, plan to yours.

Consistency rules — frequently asked
What is a prop firm consistency rule?
It’s a cap on how much of your total profit can come from a single day. If a firm sets a 30% best-day cap and you finish with $3,000 in profit, no single day may account for more than $900 of it. Firms use it to filter out one-lucky-trade accounts, and it usually applies to a payout request or an evaluation pass rather than to individual trades.
How do I calculate my consistency percentage?
Divide your best day by your total profit: a $1,200 best day inside $4,000 of profit is 30%. The calculator above works the other way round, which is the more useful direction — it takes the target you need and the days you plan to spread it across, and shows the per-day number that keeps your biggest day inside the cap.
How many days does a consistency rule force me to trade?
Divide 100 by the cap and round up. A 50% cap needs at least 2 profitable days, a 40% cap needs 3, a 30% cap needs 4, and a 20% cap needs 5 — before any minimum-trading-days rule your firm applies separately. The calculator shows this as "min days at" your cap, which is the number most traders never work out until a payout is questioned.
What happens if I break the consistency rule?
That depends entirely on the firm and the program. Common outcomes are a payout being adjusted or delayed until the account is back inside the cap, or having to keep trading to grow the total profit the big day is measured against — some firms treat it as a hard breach instead. Read your own account agreement; MAV can’t tell you how your firm will handle it.
Which prop firms have a consistency rule?
It varies by firm, by program and by stage — evaluation caps and funded/payout caps are often different numbers, and some plans have no cap at all. The table above shows only what MAV’s own rule sets model, and says "none modelled" where MAV applies no cap. Always confirm your program’s current rule with the firm; these are planning figures, not contractual values.
Is this consistency calculator free?
Completely free, and no login is required. The same calculator sits inside MAV’s Learning academy next to a playbook for each firm, and Learning is included on the free plan — so you can keep it alongside your journal without paying.
