Futures Prop Firm Consistency Rule Calculator: 30%, 40% and 45% Examples
A futures prop firm consistency rule usually limits the trader's largest profitable day to a percentage of total profit. If the rule is 30% and the best day is $900, total profit generally needs to reach at least $3,000 because $900 ÷ $3,000 equals 30%.
Core Formula
Consistency percentage = largest profitable day ÷ total profit × 100
To calculate the total profit required:
Required total profit = largest profitable day ÷ consistency limit
The firm's exact definition may exclude losing days, reset after payout or use another measurement. Always confirm the written policy.
Required Total Profit by Best Day
| Largest profitable day | 30% rule | 40% rule | 45% rule |
|---|---|---|---|
| $300 | $1,000.00 | $750.00 | $666.67 |
| $500 | $1,666.67 | $1,250.00 | $1,111.12 |
| $750 | $2,500.00 | $1,875.00 | $1,666.67 |
| $900 | $3,000.00 | $2,250.00 | $2,000.00 |
| $1,000 | $3,333.34 | $2,500.00 | $2,222.23 |
| $1,500 | $5,000.00 | $3,750.00 | $3,333.34 |
Values are rounded upward where necessary so the best day does not exceed the limit.
Worked 30% Example
A trader has the following results:
| Day | Profit or loss | Running total |
|---|---|---|
| 1 | +$900 | $900 |
| 2 | +$600 | $1,500 |
| 3 | +$500 | $2,000 |
| 4 | +$400 | $2,400 |
| 5 | +$300 | $2,700 |
The best day is $900. At $2,700 total profit:
$900 ÷ $2,700 = 33.33%
The account does not yet meet a 30% limit in this model. Total profit must reach $3,000, requiring another $300 without creating a larger best day.
Worked 45% Example
| Day | Profit | Running total |
|---|---|---|
| 1 | $900 | $900 |
| 2 | $600 | $1,500 |
| 3 | $500 | $2,000 |
The best day is $900 and total profit is $2,000.
$900 ÷ $2,000 = 45%
This meets a 45% limit exactly, assuming the firm's rule uses this standard formula.
How a New Best Day Changes the Requirement
| Current best day | New best day | 30% required total before | 30% required total after |
|---|---|---|---|
| $500 | $700 | $1,666.67 | $2,333.34 |
| $750 | $1,000 | $2,500.00 | $3,333.34 |
| $900 | $1,200 | $3,000.00 | $4,000.00 |
A very large winning day can increase the total profit needed, even though the account balance improves.
Planning Daily Profit Without Chasing the Rule
Set a soft daily objective
A soft objective is not a guarantee or a hard stop. It helps prevent one day from dominating the total.
Reduce size after an outsized day
Lower size can allow total profit to catch up without creating another larger day.
Do not force extra trades
Trading solely to satisfy consistency can introduce avoidable risk. The account's drawdown rule still applies.
Check whether losses affect the denominator
Some firms use net profit; losing days can reduce total profit and raise the consistency percentage.
Consistency Worksheet
| Input | Value |
|---|---|
| Largest profitable day | |
| Current total profit | |
| Consistency limit | |
| Current percentage | |
| Required total profit | |
| Additional profit needed |
Use:
Additional profit needed = required total profit − current total profit
If the result is zero or negative, the mathematical limit is met under the assumed formula.
Consistency Versus Minimum Profitable Days
These are different rules.
| Rule | What it measures |
|---|---|
| Consistency percentage | Largest day relative to total profit |
| Minimum trading days | Number of days with any qualifying activity |
| Minimum profitable days | Number of days meeting a profit threshold |
| Daily profit cap | Maximum profit counted or allowed per day |
| Payout consistency | Distribution of profit before withdrawal |
Final Answer
Divide the largest profitable day by the allowed consistency percentage to find the minimum total profit. A $900 best day requires $3,000 under a 30% rule, $2,250 under a 40% rule or $2,000 under a 45% rule. Confirm the firm's exact definition before relying on the result.
