Prop Firm Static Drawdown Calculator

Estimate how many trading days it takes to reach your profit target with static or fixed drawdown limits. This calculator helps validate your strategy for prop firm evaluations that use static drawdown rules, where your maximum loss limit remains fixed throughout the challenge.

How to Use the Calculator

Step 1: Set Your Account Size

Enter your evaluation account size (typically $25K, $50K, $100K, or $150K depending on your challenge).

Step 2: Input Profit Target

Enter the total profit you need to achieve. This is typically the prop firm challenge requirement to pass an eval (for example: $3,000 for a $50K account).

Step 3: Input Maximum Loss Limit

Input the maximum total loss you can sustain before account termination. This should reflect your prop firm's rules or personal risk tolerance.

Step 4: Set Daily Profit Limit

Input your average profit on winning days based on your strategy and position sizing. Use realistic expectations, not best-case scenarios.

Step 5: Set Daily Loss Limit

Enter your average loss on losing days, including all trading costs (commissions, spreads, slippage). This is often higher than daily profits due to risk management.

Step 6: Adjust Your Win Rate

Use the slider to set your realistic win rate percentage based on backtesting or proven track record data.
