What Are Assessment Fees?

Assessment fees, sometimes called dues and assessments, are charges the card networks themselves levy on every transaction you accept. They are separate from interchange, and like interchange they are set by the networks and passed through to you at cost. No one in the payment chain marks them up or negotiates them away.

How it works

Each card network sets its own assessment. The fee is generally a small percentage of the transaction amount, often paired with smaller per-item or volume-based components depending on the network and card type. Visa, Mastercard, Discover, and American Express each publish their own rates, and those rates apply uniformly to everyone accepting those cards.

When you pay for a transaction, the cost typically breaks into three layers:

The first two layers are the "wholesale" cost of accepting a card. The third layer is the part a provider actually controls, and it is the part worth comparing across offers.

On an interchange-plus statement, assessments usually appear on their own line, separate from interchange and separate from the markup. On a tiered, flat-rate, or surcharge statement, assessments are bundled into the rate you see, so they are still being charged, just not itemized.

Why it matters to you

Assessment fees are unavoidable, so the goal is not to eliminate them but to see them clearly. Knowing they are a fixed, pass-through cost helps you read a statement honestly: if two providers quote different prices, the difference is in the markup, not the assessments. A statement that breaks out assessments separately gives you a verifiable trail back to published network rates, which is one practical way to confirm you are being charged what you should be and nothing more.
