1. What is the Transaction Fee Formula?

The transaction fee formula calculates the total fee for credit card payments, combining a percentage of the transaction amount with a fixed fee. This is commonly used by payment processors to determine their charges.

2. How Does the Calculator Work?

The calculator uses the transaction fee formula:

Where:

• \( P \) — Transaction amount (currency unit)
• \( R_f \) — Fee rate (e.g., 2.5% as 0.025)
• \( C \) — Fixed fee (currency unit, e.g., $0.10)
• \( F \) — Total fee (currency unit)

Explanation: The formula accounts for both the variable percentage-based fee and any fixed processing charges.

3. Importance of Fee Calculation

Details: Accurate fee calculation is crucial for businesses to understand their true costs, set appropriate pricing, and maintain profitability when accepting credit card payments.

4. Using the Calculator

Tips: Enter the transaction amount in dollars, the fee rate as a decimal (e.g., 2.5% as 0.025), and any fixed fee in dollars. All values must be non-negative.
