Prop Firm Risk Calculator

Prop firms like FTMO, TopStep, and Quant Tekel enforce max daily and total drawdown. Enter your account size, rule percentages, and today's P&L to see remaining risk budget.

Key takeaway: If your firm allows 5% max daily loss on a $100,000 account, your daily loss budget is $5,000. After −$2,000 today, only $3,000 of risk remains before the rule fails the account.

Calculator

Daily loss limit = account × (max daily % ÷ 100). Remaining budget = limit − |today's loss| if P&L is negative; if positive, full limit still available until you give back gains.

Negative = losing day. Include open trade unrealized if your firm counts it.

FAQ

Does Profit AI track prop firm rules?
Partly. Profit AI syncs prop accounts on MT5 or cTrader (such as FTMO on MT5) and imports others, like TopStep, by CSV. You set your firm's daily loss and risk limits as playbook rules, and every trade and day is graded against them. It does not monitor your account live or warn you before a trade, so use this calculator to plan the remaining budget.
Is max daily loss calculated on balance or equity?
Firms differ. FTMO typically measures from the day's starting balance. Always read your firm's rule PDF — this calculator assumes a simple percent-of-account-size model for planning.
