The rule and pricing shifts that actually affect what a small business pays
2026 brought the most meaningful set of card acceptance changes in years. A long-running interchange settlement received court approval, delivering a modest reduction in average effective credit interchange along with new merchant rights around surcharging and card acceptance. At the same time, the networks pushed through their usual spring and fall fee schedules, adding new categories and raising several assessments. The net effect for most small businesses is not one dramatic price drop, but a wider set of levers for controlling cost. This guide explains what moved, what did not, and what to review on your own statement.
The headline change is a reduction of roughly ten basis points (0.10%) in the combined average effective interchange rate on eligible U.S. credit transactions, running for a multi-year period. It applies to U.S.-issued consumer and commercial credit cards; debit, PIN debit, prepaid, and foreign-issued cards are outside the scope. On $500,000 of qualifying credit volume, ten basis points is about $500 a year — real, but not transformative on its own.
The more durable changes are structural. Merchants gained expanded ability to surcharge at the product level rather than all-or-nothing, more freedom to decline specific card categories or wallet forms, and a pathway for groups of merchants to negotiate collectively with the networks.
Interchange is only part of the bill. Network assessments and service fees were updated in 2026, including higher digital commerce service fees, expanded authorization-related fees that apply even to declined attempts, and new interchange categories for certain commercial and card-not-present transactions. Merchants who saw only the settlement headline were often surprised when their effective rate did not fall.
Programs that reward enhanced transaction data expanded in 2026, while some older Level 2 incentives were retired. B2B and government-facing merchants that submit richer line-item data can qualify for lower rates; those that do not are increasingly downgraded to more expensive categories.
Pull three recent statements, calculate your effective rate, and check whether the 2026 changes actually reached your account. If they did not, that usually points to markup or downgrades rather than interchange. Cash discounting remains the most direct way to remove processing cost from the P&L entirely, regardless of how network schedules move next.
Eligible credit interchange came down modestly, but several network fees rose in the same period, so many merchants saw a flat or slightly higher effective rate.
No. The interchange relief covers U.S.-issued credit cards; debit, PIN debit, prepaid, and foreign-issued cards are excluded.
Nothing is required of you, but the savings only reach you if your pricing model passes interchange through. Flat-rate and tiered plans often absorb it.
Not materially. A tenth of a percent off interchange does not offset a typical 2.5%–3.5% all-in cost, which is what a cash discount program is designed to address.
