The real cost of accepting card payments in 2026
Interchange, assessments, and processor markup are not the same thing. Here is how to read a merchant statement, and where the savings actually hide.
Most small business owners know card acceptance costs money. Fewer know that the fee on their statement is really three fees wearing one coat: interchange set by the card networks, assessments charged by the brands, and the processor markup on top. Only one of the three is negotiable.
Why statements stay confusing
Interchange-plus pricing separates the wholesale cost from the provider margin, which makes comparison possible. Bundled or tiered pricing folds everything into qualified, mid-qualified, and non-qualified buckets, which makes comparison nearly impossible. Two providers quoting the same headline rate can differ by half a percentage point once the buckets are filled.
Where the savings hide
For a merchant processing fifty thousand dollars a month, a quarter-point of margin is roughly fifteen hundred dollars a year. The biggest levers are usually the pricing model, the markup on card-not-present transactions, and junk fees with names like batch, PCI, and statement fees.
What to do about it
Ask any provider three questions: Is this interchange-plus? What is the exact markup over wholesale? Which fees are fixed monthly regardless of volume? A provider that answers all three in writing is usually the one that earns the account. Straight answers are the entire product.
