1. What is the Credit Card Fee Formula?

The credit card fee formula calculates transaction fees for credit card payments. It accounts for both a percentage-based fee and a fixed fee component that many payment processors charge.

2. How Does the Calculator Work?

The calculator uses the credit card fee formula:

Where:

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

Explanation: The formula calculates the variable portion (percentage of transaction) plus any fixed fees charged by the payment processor.

3. Importance of Fee Calculation

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

4. Using the Calculator

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