Prop firm drawdown calculator
See exactly how much room you have left today on a funded account: daily loss limit, static or trailing max drawdown, and how many full losses you can take.
The two limits that end most challenges
Daily loss limit. How far the account can fall in one day, usually measured from the balance (or equity, at some firms) when the day started. With a 5% limit on a 50,000 account you cannot go below 47,500 on a day you started at 50,000. Open losing trades count.
Overall (max) loss limit. The line the account can never cross. A static limit is a fixed floor: 10% on 50,000 is 45,000, for ever. A trailing limit follows your highest balance up, so after a winning run the floor rises too. At most firms it stops rising once it reaches the starting balance.
Why the closer limit is the one that matters
Your real room on any day is the gap to whichever line is nearer. Early in a challenge it is usually the daily limit. After a losing week it can be the overall one. The calculator shows both and tells you which is closer, so you can size today’s trades to it.
Rules differ between firms and change often. Always check your own firm’s rulebook, including whether limits use balance or equity and what time their day resets.
Questions people ask
Is a trailing drawdown worse than a static one?
Usually, yes. A trailing limit rises with your best balance, so a winning run followed by a normal losing run can breach it even though you are still in profit overall. Static limits are more forgiving for strategies with fixed, small stops.
Do open trades count towards the daily loss limit?
At most firms, yes: the limit is checked against equity, which includes floating losses. A trade that dips below the line and recovers can still fail the account.
How much should I risk per trade on a funded account?
Small enough that several full losses in a row stay well inside the daily limit. Many traders use 0.25% to 0.5% per trade during a challenge.
