Prop Firm Trailing Drawdown Calculator — FTMO, TopStep, Apex

The prop firm trailing drawdown calculator shows you exactly where your drawdown floor sits based on your highest achieved balance. Trailing drawdown moves up as your balance grows — it never moves back down. If your balance falls to the floor, you fail the challenge or funded account. This calculator supports FTMO (relative 10% trailing), TopStep (trailing to starting balance), Apex (trailing intraday), and fully custom rules.

Floor = Peak ($102,000) − Max Loss ($10,000) = $92,000. Trailing drawdown follows your peak balance.

Formula Used

Drawdown Floor = Peak Balance − (Starting Balance × Max Drawdown %) | Distance to Breach = Current Balance − Floor

Trailing Drawdown Calculator — Frequently Asked Questions

Q.What is trailing drawdown in prop firms?

Trailing drawdown is a maximum loss rule that follows your highest balance. If your FTMO $100K account reaches $105K, the trailing floor moves up from $90K to $95K. You can never recover lost floor — it only moves up. If your balance hits the floor, you fail.

Q.What is the FTMO trailing drawdown rule?

FTMO uses a relative (trailing) max loss of 10% of the initial account balance. For a $100K account, the max drawdown is $10,000. The floor moves up as your balance grows — at $105K peak, the floor is $95K. The daily loss limit is 5% ($5,000 for a $100K account).

Q.What is TopStep trailing drawdown?

TopStep uses an intraday trailing drawdown based on your highest intraday equity. For a $50K combine, the trailing drawdown is $2,000. It follows your highest intraday balance — if you reach $51,000 intraday, your floor becomes $49,000. It stops trailing once you reach the starting balance, creating a permanent floor.

Q.Does trailing drawdown move when I make profits?

Yes — trailing drawdown floors move up when your balance increases. If you start with $100K, max drawdown $10K (floor at $90K), and grow to $103K, your floor moves to $93K. This means consistent profits lock in your drawdown floor at a higher level, giving you less room for losing streaks.

Q.How do I protect my prop firm account from breaching trailing drawdown?

Risk no more than 0.5–1% per trade. Use a position size calculator to ensure each trade cannot breach your floor alone. Keep a daily loss limit well inside the prop firm rule — if the firm allows $2,000 daily loss, stop at $1,000. Never revenge trade after losses. The floor is merciless: one bad day can end the account.
