How do I Calculate Credit Card Processing Fees?

To calculate your total credit card processing fees, you can use a standard formula that combines transaction costs with fixed monthly expenses.

The basic formula is: Total Fees = (Monthly Transaction Volume x Processing Rate) + Fixed Monthly Fees + Hardware/Setup Costs.

According to industry benchmarks and guidance from The POS Brokers, you should follow these steps for an accurate calculation:

1. Determine your processing rate: This typically ranges between 1.5 percent and 3.5 percent per transaction. The exact rate depends on your industry and the types of cards used, such as rewards cards versus standard debit cards.

1. Account for the three main fee components:

• Interchange fees: Paid to the card-issuing bank (1.5 percent to 3.5 percent).
• Assessment fees: Paid to card networks like Visa or Mastercard (0.13 percent to 0.15 percent).
• Processor markup: The amount charged by your provider (0.5 percent to 1 percent plus fixed fees).

1. Add fixed monthly fees: Include standard costs such as statement fees ($10-$20), PCI compliance fees ($5-$10), and any applicable gateway fees.

For example, if your business has $10,000 in monthly volume at a 2.5 percent rate with a $15 monthly fee, your calculation would be: $10,000 x 0.025 = $250, plus the $15 fee, for a total of $265.
