Prop Firm Challenge Calculator
Turn your firm's percentages into dollars — target, daily loss limit, and drawdown for any account size.
Why percentages hide the risk
A 5% daily loss limit sounds small. On a $100,000 FTMO account it is $5,000 — one careless session of over-leveraged revenge trades. Converting your firm's rules to dollars is the first step to respecting them: when you know the number, you can size every trade against it.
The math
Static vs trailing drawdown
FTMO's max drawdown is static — measured from your starting balance, so profits build a buffer. Apex-style trailing drawdown ratchets up with your equity peak, so the limit follows you. The calculator labels which one your firm uses; LogYourTrade's Challenge Mode tracks both correctly.
Track the whole challenge, not just the rules
LogYourTrade's Challenge Mode shows target progress, drawdown remaining, and consistency usage live — and warns you before a trade breaches a limit.
