How the floors work
The daily floor resets every trading day: day-start balance × (1 − daily%). The max floor is fixed from your starting account size: account × (1 − max%) — on most firms it never moves. Whichever floor is closer to your current equity is the one that ends the challenge, and it's usually the daily one: you can be miles from the 10% line and still fail the day by lunchtime.
Honest limits of this calculator: some firms measure the daily limit from the day's starting equity rather than balance, and trailing-drawdown firms (Apex and most futures funders) raise the max floor with your equity high-water mark — this calculator models the static balance-based rules used by FTMO, FunderPro, E8 and The5ers. Always confirm the exact wording in your firm's dashboard.

FAQ
Frequently asked questions
How is prop firm daily drawdown calculated?
Most firms set the daily floor at the day's starting balance minus the daily limit percentage — e.g. a $100,000 FTMO account with a 5% daily limit that starts the day at $102,000 breaches if equity touches $96,900 (102,000 × 0.95). Some firms use the day's starting equity instead of balance, so always confirm your firm's exact rule.
What is the difference between static and trailing max drawdown?
A static max drawdown floor never moves — e.g. FTMO's $90,000 floor on a $100,000 account. A trailing drawdown (used by Apex and some futures firms) rises with your equity high-water mark, so profits raise the floor beneath you and the room never grows past the trail distance.
How many losing trades until I breach my prop firm challenge?
Divide your remaining drawdown room by your per-trade risk. With $4,000 of room and 1% risk on a $100,000 account ($1,000 per trade), four consecutive full losses breach the account — which is why funded traders commonly risk 0.5–1% per trade.
