What a Payment Costs You
Break a headline rate into interchange, scheme fee and processor markup, and say why UPI merchant transactions in India carry no such rate at all.
A card payment fee is a bundled price: issuer compensation, card network charges, and processor margin are collected together but paid to different parties. The processor may invoice the merchant, yet card type, geography, merchant category and routing determine how much is passed through. UPI merchant pricing in India is a policy exception, not just a lower-cost card rail.
What this lesson answers
- what is included in card processing fees
- why does payment processor not keep full fee
- why is UPI free for merchants in India
Notes
When a merchant accepts a card payment, the quoted “2.9% + 30¢” style price is not one single fee. It is a bundle. Part of it goes to the card-issuing bank as interchange, part goes to the card network as scheme or network fees, and the rest is the processor or payment service provider’s markup for routing, risk tools, settlement, reporting, support, and profit.
A useful mental model is to treat a card payment like a message that crosses several paid checkpoints. The customer’s bank takes compensation for providing credit or debit access and bearing some risk.
Common questions
- What is interchange in a card payment?
- Interchange is the part of a card transaction fee paid to the customer’s card-issuing bank. It compensates the issuer for enabling the card payment, handling authorisation, and taking on aspects of credit, debit, fraud, and repayment risk. It is usually collected by the processor from the merchant, then passed through rather than retained as processor revenue.
- What are scheme fees or network fees?
- Scheme fees are charges paid to the card network for using its payment rails, rules, authorisation infrastructure, and settlement framework. They are separate from interchange and from the processor’s own markup. A merchant may see only one blended headline price, but the underlying cost stack includes these network charges.
- Why do UPI merchant payments in India not have a card-style MDR?
- Many UPI merchant transactions in India operate under a zero merchant discount rate policy. That means the merchant is not charged the familiar card-style percentage that gets split between issuer, network, and processor. The absence of that rate comes from the policy and market structure around UPI, not from UPI being a cheaper card network.
