Prop Firm Drawdown Calculator
See where your drawdown floor sits under intraday trailing, end-of-day trailing and static rules, day by day, and check whether your profits pass a consistency rule. Type in your own numbers or edit the example.

Intraday trailing vs end-of-day trailing drawdown
Both rules move your floor up as your account grows, and neither moves it back down. The difference is which balance they follow.
- Intraday trailing follows the highest balance reached at any moment, including open profit on a trade you have not closed. If a trade runs $1,500 in your favour and you give it back, the floor has already moved up $1,500.
- End-of-day (EOD) trailing only updates after the session closes, using the closing balance. Open profit during the day does not move the floor. During the day you can lose down to the floor set at the previous close.
- Static drawdown never moves: the floor is always the starting balance minus the maximum drawdown.
Most rule sets stop trailing once the floor reaches a set level, often the starting balance. After that point the floor stays put, and every dollar above it is room you keep.
The calculator does not know the order of the high and the low within a day, so it assumes the worst case for intraday trailing: the high came first and moved the floor before the low. Firms also differ in details such as whether fees count and when the day closes, so check your own firm's rule page.
Worked example
A $50,000 account with a $2,000 trailing drawdown that stops at $50,000. On day 1 a trade runs the balance up to $51,200 and the day closes at $50,600.
- Intraday trailing: the floor is $51,200 − $2,000 = $49,200. With the account at $50,600, you have $1,400 of room.
- EOD trailing: the floor follows the close, $50,600 − $2,000 = $48,600, so you have $2,000 of room going into day 2.
- Static: the floor stays at $48,000, $2,600 of room.
Same trades, different risk. On an intraday trailing account the open profit you did not take still cost you $600 of room.
How the consistency rule works
A consistency rule limits how much of your total profit can come from a single day. With a 40% rule, your best day must be no more than 40% of your total profit. If your best day is $1,200, you need at least $1,200 ÷ 0.40 = $3,000 of total profit before you qualify. The calculator shows the share of your best day and, if you are over the limit, how much more profit you need without beating that best day.
Some firms apply the rule to the evaluation, others only to payouts, and the percentage varies (30%, 40% and 50% are common). Use the number from your firm's current rules.
Frequently asked questions
What is a trailing drawdown?
A trailing drawdown is a loss limit that moves up as your balance reaches new highs, always staying a fixed distance below the highest balance. It never moves down, so profits you give back still reduce your room.
Is end-of-day trailing drawdown better than intraday?
For most traders, yes: an end-of-day drawdown only moves on closing balances, so open profit you do not keep does not raise the floor. The trade-off is that during the day you can only lose down to the floor set at the previous close.
When does a trailing drawdown stop trailing?
Many firms stop moving the floor once it reaches the starting balance, and some add a small amount such as $100. After that point the floor stays fixed. Enter that level in the calculator to see the effect.
How do I calculate the consistency rule?
Divide your best day by your total profit. With a 40% rule, the result must be 40% or lower. If it is higher, you need total profit of at least best day divided by 0.40 before you qualify.
Does the calculator know my prop firm rules?
No. It applies the rule you type in. Firms change their rules and differ on details such as fees, the closing time and when a breach is checked, so always confirm on your firm's current rule page.
