Prepare for Your Prop Firm Challenge

Understanding your numbers is an important part of evaluating a prop firm challenge. Explore BEM Funding's challenges, review their requirements, and use the available calculators to help you understand relevant trading metrics before getting started. Always consult the official challenge rules for the applicable conditions.

  • Drawdown Calculator
  • Consistency Calculator

 

Prop Firm Drawdown Calculator

Calculate your drawdown limits and understand how much room you have before reaching your account's loss limits. Use the Drawdown Calculator to estimate your daily loss limit, maximum drawdown, and remaining drawdown allowance based on your account size and challenge rules.

 

Calculate Your Drawdown

Enter your account balance and drawdown rules to calculate your loss limits and remaining risk allowance.

 

What Is Drawdown in a Prop Firm?

Drawdown is the amount an account can lose before reaching a specified loss limit. Prop firms may set daily drawdown limits, maximum overall drawdown limits, or both. These rules determine how much an account can decline before a challenge or funded account breaches its trading conditions.

 

How to Calculate Drawdown

To calculate a percentage-based loss limit, multiply the account size by the applicable drawdown percentage.

Example: For a hypothetical $100,000 account with a 5% daily drawdown limit, the daily loss limit would be $5,000.

Actual calculations may differ depending on whether the firm's rules use the initial balance, current balance, equity, closed trades, or floating losses.

 

Why Drawdown Rules Matter

Understanding drawdown limits helps traders monitor their risk, evaluate challenge conditions, and avoid accidentally breaching account rules. Before trading, check whether your prop firm calculates drawdown using balance or equity and whether daily limits reset at a specific time.

Disclaimer: This calculator provides estimates for educational purposes only. Actual drawdown calculations and breach conditions depend on the applicable prop firm's official rules. Always review the relevant challenge terms before trading.

 

Prop Firm Consistency Calculator

Calculate your trading consistency and see how your profits are distributed across your trading days. The Prop Firm Consistency Calculator helps you understand how much of your total profit comes from your most profitable day and estimate whether you meet a specified consistency threshold.

 

Calculate Your Trading Consistency

Enter your total profit, your highest-profit day, and the consistency threshold specified by your prop firm.

 

What Is a Consistency Rule in a Prop Firm?

A consistency rule is a condition some prop firms use to limit how much of a trader's total profit can come from a single trading day or a small number of trades. The exact calculation and threshold vary by firm and challenge type.

 

How Is Trading Consistency Calculated?

A common method is to divide the highest-profit day by the total profit and multiply by 100.

Example: If your total profit is $5,000 and your highest-profit day is $2,000, that day represents 40% of your total profit.

Whether this meets a consistency rule depends on the threshold and calculation method defined by the prop firm.

 

Why Does Trading Consistency Matter?

Understanding consistency requirements can help traders evaluate their progress and check whether their results meet a challenge's conditions. Always review the official rules to confirm how consistency is calculated and when it applies.

Disclaimer: This calculator provides estimates for educational purposes only. Consistency requirements differ between prop firms and challenge types. Check your firm's official terms before making trading decisions.
