Consistency Rule Calculator

Plan an appropriate best-day profit limit before trading, or enter your current results to see whether your account meets the consistency rule and how much total profit may be required.

What is a consistency rule?

A rule that measures how much of your profit came from your best trading day

The smaller your best trading day is relative to total profit, the lower your consistency ratio. For example, a $200 best day and $1,000 total profit produces a 20% consistency ratio.

Consistency Ratio Best Trading Day ÷ Total Profit × 100
01
Before You Start

02
Current Trading Results

Check Your Current Consistency

Enter your current profit figures to calculate your ratio and the total profit required to meet the firm's limit.

How to Read the Result

Two ways to use the consistency rule

Planning

Set a best-day ceiling

Use your total profit target and the firm's limit to plan a maximum best trading day.

Compliance

Check your current ratio

Compare your current best day with total profit to see whether the account is compliant.

Recovery

Calculate the profit still required

If the ratio is too high, the calculator shows how much total profit is needed without increasing the best day.

Prop firms may define the consistency rule differently. Always confirm whether the firm uses closed profit, daily equity, payouts, or another calculation method.
