Drawdown Calculator
for Prop Firm Traders.
Every prop firm account has a drawdown limit. Enter your account details to find your exact breach level, see how much room you have left, and how much you can risk per trade without getting close to it.
Rule settings
Copy these from your prop firm's rulebook. They differ between firms and between account stages.
Static: the breach level is fixed at account size minus max drawdown and never moves.
Your account now
Use your current balance or equity, whichever your firm measures drawdown on.
What the drawdown rule checks
Set the drawdown amount
Max drawdown is a percentage of your starting account size, for example 10% of a $100,000 account is $10,000.
Find the breach level
On a static account the level never moves. On a trailing account it rises with your highest balance or equity, and some firms lock it once it reaches your starting balance.
Size risk to the distance
The gap between your current balance and the breach level, or your daily limit if it is closer, is the most you can lose. Split it by the losing streak you want to survive.
Check your firm's rulebook: some firms measure drawdown on balance, others on equity including open trades. Trailing may update intraday or only at the end of the day, and daily limits may be based on the start-of-day balance or the initial account size. Rules and percentages change, so confirm the exact wording with your firm before relying on this result.
