Drawdown Calculator for Prop Firm Daily Loss and Max Loss Rules
The Drawdown Calculator is built for prop firm traders who need to know exactly how much room remains before a daily loss or maximum loss rule is breached. Prop firm rules can be strict, and a trader who does not know the stop-out level is trading blind. This tool helps estimate daily loss room, max loss room, and a conservative risk amount for the next trade.
Enter your starting balance, current equity, highest equity today, highest account equity and the firm’s loss limits. The calculator can estimate both fixed and trailing drawdown styles. It then shows the calculated fail levels and how much room is left before the account gets too close to a violation.
This page is especially useful before London session, New York session, major news events, or after a losing trade. If drawdown room is tight, the smarter move is often to reduce trade size, stop trading for the day, or wait for a cleaner setup. Protecting drawdown is one of the most important skills for passing and keeping funded accounts.
