Prop Firm Drawdown Calculator: Check Your Real Risk
Most funded traders don’t blow the challenge because they can’t find trades. They blow it because they misunderstood the drawdown rule, sized too big, and breached on a day that felt fine. This calculator shows you your real limits before that happens: your max loss, your daily loss, and exactly how close you are to the floor.
How does prop firm drawdown work?
Prop firm drawdown is the maximum your account can lose before the firm closes it. There are usually two limits: a max total drawdown (your hard floor from the start balance) and a daily drawdown (the most you can lose in a single day). Breach either and the challenge or funded account is over, which is why knowing the exact figures before you trade matters more than the entry.
How to read your result
- Max total loss is your hard ceiling on losses from the starting balance. Hit the floor and the account is gone.
- Daily loss resets each day. Many firms measure it from your start-of-day balance or equity, so check your firm’s exact wording.
- Static vs trailing. A static floor stays fixed from your start balance. A trailing floor follows your highest equity up, so banking profit can quietly raise the level you must not fall below. This is where careful traders still get caught, the full breakdown is in the prop firm drawdown rules guide.
- Buffer is how much room you have left before the floor. When it gets thin, size down or stop, do not try to trade your way out.

The mistakes that breach accounts
- Sizing to the daily limit instead of well inside it. One bad fill near your cap and you breach.
- Forgetting the floor trails. On a trailing account, a green run lifts the floor, so a normal pullback can breach you even while you’re up on the week.
- Trading through news like NFP and CPI at full size, gold and indices can gap straight through a stop.
- Revenge trading after a red day to “get back” to the start balance, the fastest route to the floor there is.

FAQ
How is prop firm drawdown calculated?
Max total drawdown is your account size multiplied by the max drawdown percentage, giving the hard floor your balance cannot fall below. Daily drawdown is the account size multiplied by the daily percentage. The calculator above works both out and shows how much buffer you have left.
What is the difference between static and trailing drawdown?
A static floor is fixed from your starting balance. A trailing floor follows your highest equity upward, so as you bank profit the level you must not fall below rises with you. Trailing is stricter and catches more traders, because a normal pullback can breach it even while you’re in profit.
What happens if I hit the drawdown limit?
The firm closes the challenge or funded account, usually immediately and automatically. There’s normally no warning and no second chance on that account, which is why staying well inside your limits matters far more than any single trade.
How much should I risk per trade on a prop account?
Small enough that a normal losing run cannot bring you near the floor. Many funded traders risk well under 1% per trade and keep total open risk a fraction of the daily limit, so one bad session never ends the account.
Is daily drawdown based on balance or equity?
It depends on the firm. Some measure it from your start-of-day balance, others from equity including open trades, and the reset time varies too. Always confirm your specific firm’s wording, because trading right up to the limit on the wrong definition is how people breach by accident.
Educational tool, not financial advice. Calculations are estimates based on your inputs, always confirm your prop firm’s exact drawdown rules, reset times and definitions, which vary by firm and can change. Trading is leveraged and carries a high risk of losing money rapidly; most retail and funded traders lose money.
