Prop firm consistency rules: formula and worked examples
A consistency rule limits how much of the relevant period’s profit can come from your best trading day. The percentage, measurement period and consequences depend on the exact program and account stage.
Calculate your best day’s share of profit
Consistency percentage = largest profitable day ÷ total eligible profit for the same period × 100. Use the provider’s trading-session cutoff and profit definition, including its treatment of commissions, losses and open positions.
Suppose four hypothetical days finish at +$400, +$800, +$300 and +$100 after trading costs. Total profit is $1,600 and the best day is $800, so consistency is $800 ÷ $1,600 × 100 = 50%. The denominator is profit earned, not an advertised $50K account balance.
The examples below assume a positive net-profit total, an inclusive ceiling, and no separate percentage cushion. Daily profits do not need to be equal; the largest day’s share must fit the rule. A zero or negative total cannot establish compliance with this positive-profit ratio.

Work out how much total profit is needed
Required total profit = best-day profit ÷ the limit as a decimal. Additional profit needed = required total minus current total, with a minimum of $0. Round the required amount up to the next cent when the division does not produce whole cents.
This table keeps the best day at $800 and current total profit at $1,600. The four limits are hypothetical illustrations, not a comparison of current firm policies. The remaining amount assumes the best day does not increase.
| Hypothetical limit | Required total profit | Additional profit needed |
|---|---|---|
| 20% | $800 ÷ 0.20 = $4,000 | $2,400 |
| 30% | $800 ÷ 0.30 → $2,666.67 | $1,066.67 |
| 40% | $800 ÷ 0.40 = $2,000 | $400 |
| 50% | $800 ÷ 0.50 = $1,600 | $0 |
Recalculate after a loss or a new best day
A losing day reduces total net profit without reducing the existing best day. With an $800 best day and $2,000 total, the ratio is 40%. A later $200 loss lowers the total to $1,800 and raises the ratio to about 44.44%. Deliberately taking a loss does not improve this calculation.
A new largest day changes the required total. Start with the table’s $800 best day and $1,600 total under a hypothetical 40% limit. If the next day earns $1,400, total profit becomes $3,000 and the best day becomes $1,400. The ratio is about 46.67%; the revised required total is $1,400 ÷ 0.40 = $3,500, leaving $500 still needed.
Check the exact amounts instead of relying on a rounded percentage display. At a 30% ceiling, an $800 best day needs $2,666.67: $2,666.66 leaves the ratio slightly above 30%.

Separate evaluation rules from payout rules
An evaluation rule can affect when you pass. A simulated-funded rule can affect a payout request, and its measurement period may restart after an approved payout. Neither stage establishes the terms of a later live brokerage account.
For example, Tradeify’s official consistency page distinguishes its Select evaluation requirement from Select funded accounts, which have no consistency rule. MyFundedFutures separately identifies applicable Rapid and Pro evaluation rules and excludes its Pro one-day-pass option. A firm name alone does not identify the rule for an account.
Use Boxcar’s consistency support guide for its current plan-by-stage percentages, evaluation cushion and payout-cycle calculation. Keep profit from an earlier completed cycle out of a calculation that measures only the current cycle.

Passing consistency is only one eligibility check
Being above a consistency ceiling is not automatically an account breach. Boxcar describes it as delaying passing or payout eligibility; MyFundedFutures likewise says exceeding its applicable evaluation target does not itself breach the account. Check the consequence stated for your own program.
A $0 consistency shortfall does not establish a payout amount. Profit targets, qualifying days, retained buffers, caps and approval requirements can still apply. Drawdown and daily loss limits remain separate trading boundaries.
