Consistency Rule Calculator

The consistency rule calculator checks whether your best day sits inside a prop firm's limit, then returns the minimum total profit you need before a payout unlocks. Browser-only, nothing stored.

A consistency rule caps how much of your total profit may come from one best day: consistency = best-day profit / total profit x 100, and it must stay at or below the firm's threshold; breaching it usually freezes a payout rather than failing the account.

How it works

What this calculator does

Many prop firms enforce a consistency rule: no single day's profit may exceed a set share of your total profit. This tool checks whether your best day is compliant and — given that best day — computes the minimum total net profit you need before a payout is allowed.

The formula

You're compliant when:

(best day profit / total net profit) × 100 ≤ threshold

Common thresholds are 20–40%. Rearranged, the minimum total profit you must reach is:

min total profit = best day profit / threshold

Worked example

Your best day made $1,000 and the firm's consistency threshold is 40%. Your best day can be at most 40% of the total, so 1,000 / 0.40 = $2,500 in total net profit is required before you qualify. If you've only made $1,800 so far, that one day is 56% of profits — over the limit — and you'd need more profitable days to dilute it.

What it deliberately does not do

The consistency rule does not blow your account — it freezes payouts until you comply. Thresholds and exact definitions (gross vs net, which days count) vary by firm, so confirm the rule you're under. This is a planning estimate for education, not investment advice.

Frequently asked questions

What is the prop firm consistency rule?

It caps how much of your total profit can come from a single day. If your best day exceeds the threshold (often 20–40%), the firm holds your payout until more profitable days dilute that share. It doesn't fail the account, it freezes withdrawals.

How do I calculate the minimum profit to meet the consistency rule?

Divide your best day by the threshold: best day / threshold. A $1,000 best day under a 40% rule needs 1,000 / 0.40 = $2,500 total before you can withdraw.

Does breaking the consistency rule blow my account?

No. Unlike a drawdown breach, it freezes your payout rather than ending the account. You keep trading and bring your best-day percentage back under the limit, then request the payout again.

How do I avoid one day being too big?

Don't load all your risk into a single session. Spreading profit across more days keeps any one day below the threshold. If a day runs hot, trade smaller afterward and let more green days dilute it.

Is the consistency threshold the same at every firm?

No — it ranges roughly 20–40%, and some firms use a 'best day' variant or none at all. Definitions (gross vs net, which days count) also differ, so check your firm's rule. This is an estimate for education, not investment advice.

Information tool only. Every result is deterministic arithmetic (for the simulator, a probability estimate) from the numbers you enter. The calculators run in your browser with no account connection and nothing stored; the pairs scanner uses delayed, cached market data (daily figures, refreshed once a day), not a live feed.
