THE SHORT ANSWER
There is no single average, because processing cost depends on your pricing model, card mix, average sale, and whether cards are present. Most of the cost is interchange, set by the card networks; the rest is network assessment fees and the processor’s markup and monthly fees. In-person chip and contactless payments generally cost less than online or keyed payments, and rewards and business cards cost more than basic debit cards.

Each card payment carries three kinds of cost:
For debit cards issued by large banks, the Federal Reserve’s Regulation II caps interchange at 21 cents plus 0.05% of the transaction, plus a 1-cent fraud-prevention adjustment for eligible issuers. Credit card interchange is not capped this way, so it is usually higher, especially for rewards and commercial cards.
Quoted percentages often leave out per-transaction fees, monthly and PCI fees, gateway fees, and higher rates for non-qualified transactions. The number that matters is your effective rate: total fees divided by total card sales for the month.
Take a recent monthly statement, add up every fee, and divide by your card sales. The merchant fee calculator does this for each pricing model. If your effective rate seems high, a line-by-line statement review shows which fees can be negotiated or removed.
