1. What is the Credit Card Fee Formula?

The credit card fee formula calculates the transaction fee charged by payment processors for credit card payments. It includes both a percentage of the transaction amount and a fixed fee component.

2. How Does the Calculator Work?

The calculator uses the credit card fee formula:

Where:

• \( F \) — Transaction fee (currency unit)
• \( P \) — Transaction amount (currency unit)
• \( R_f \) — Fee rate (as decimal, e.g., 2.6% = 0.026)
• \( C \) — Fixed fee (currency unit, e.g., $0.10)

Explanation: The fee consists of a percentage of the transaction amount plus a fixed amount charged per transaction.

3. Importance of Fee Calculation

Details: Understanding transaction fees helps businesses accurately calculate their net receipts from credit card payments and properly price their products or services.

4. Using the Calculator

Tips: Enter the transaction amount in dollars, the fee rate as a decimal (e.g., 2.6% as 0.026), and the fixed fee in dollars. All values must be non-negative.
