Free prop firm calculators, explained
These free prop firm calculators turn evaluation rules into the numbers that actually decide whether you pass: dollar drawdown limits, position size from your risk per trade, the pressure of a profit target, and your share of a funded account payout.
Most traders fail a prop firm challenge for avoidable reasons — oversized positions, ignoring the daily drawdown, or chasing the target too fast. Running the numbers before you trade keeps every position inside the firm's limits and makes a funded account far more realistic.
Pair these tools with our verified prop firm comparison and best-of rankings to choose a firm whose drawdown, profit split and platform actually fit your strategy before you buy a challenge.
Frequently asked questions
Are these prop firm tools free?
Yes. Every calculator on this page is free to use with no sign-up. The optional MetaTrader 5 dashboard is also free in exchange for your email.
Which calculator should I use before a challenge?
Start with the drawdown calculator to learn your dollar limits, use the lot size calculator to size each trade, then run the challenge risk calculator to check whether the target is realistic for your risk per trade.
Do the calculators replace the firm's rulebook?
No. They are planning estimates. Drawdown method, consistency rules and payout terms differ by firm, so always confirm the exact rules on the firm's own site before buying.
