A finance executive sees one blended MDR percentage on card payments and cannot tell which part goes to whom, which part is negotiable, or why some cards cost more.
Card MDR is interchange to the issuing bank plus a network fee plus the acquirer and gateway margin. Interchange and network fees depend on card type, region and ticket size; the margin is commercial.
A sample of card payments by card type from the settlement report, the gateway agreement showing blended or card-wise rates, and a monthly mix of debit, credit, premium and international cards.
The business understands why its effective card rate moves with the card mix, and knows which part of the fee it can negotiate with the gateway.
On a card payment, the MDR (merchant discount rate) you pay is split three ways. Interchange goes to the customer’s card-issuing bank. A network fee goes to Visa, Mastercard or RuPay. The rest is the acquirer and gateway margin. You usually see only one blended percentage, so the split is hidden from you.
Who gets which part of the card fee?
| Component | Who receives it | What drives it | Can you negotiate it? |
|---|---|---|---|
| Interchange | The bank that issued the customer’s card | Card type (debit, credit, premium, corporate), domestic or international, sometimes ticket size and merchant category | Not directly; set by network rules |
| Network fee | Visa, Mastercard, RuPay and others | Network, region, transaction type | Not directly |
| Acquirer and gateway margin | Your acquiring bank and payment gateway | Your volume, risk, services used | Yes, this is the commercial part |
A few terms for beginners. The issuing bank gave the card to your customer. The acquiring bank works with your gateway to receive card payments for you. The card network is the system that connects the two.
Why do premium and international cards cost more than a basic debit card?
Three reasons:
- Rewards and benefits. Premium credit cards fund points, lounge access and cashback. Higher interchange pays for them.
- Credit risk. On a credit card, the issuer lends the customer money until the bill is paid. Debit cards draw on money already in the account.
- Cross-border costs. International cards add higher network fees and currency conversion. Fraud risk is also higher.
So the same ₹10,000 sale can cost you very different amounts depending on which card the customer uses.
Worked example: where the ₹200 goes
A customer pays ₹10,000 by credit card and your blended MDR is 2 percent, so ₹200 is deducted (plus ₹36 GST at 18 percent). The split below is illustrative only, to show the idea, not a rate card:
| Component | Illustrative share | Amount |
|---|---|---|
| Interchange to issuing bank | 65 percent of the fee | ₹130 |
| Network fee | 10 percent of the fee | ₹20 |
| Acquirer and gateway margin | 25 percent of the fee | ₹50 |
| Total MDR | 100 percent | ₹200 |
If the same customer had used a basic debit card, interchange would usually be lower, but on a blended plan you would still pay ₹200. That is the subject of the next question.
Why does a flat “one rate for all cards” plan hide what each card costs?
A flat plan charges the same percentage whatever card the customer uses. That is simple to read, but it means:
- On low-cost cards, you pay more than the true cost, and the gateway’s margin is wider.
- On high-cost cards, the gateway absorbs part of the cost.
- If your customers mostly use debit cards, a card-wise (“interchange-plus”) plan may cost less. If they use many premium or international cards, flat may suit you.
Look at one month’s card mix. If 70 percent of card value is on debit cards, ask the gateway for a card-wise quote and compare.
Does the same split apply to UPI and net banking?
No. UPI does not use card interchange. UPI merchant charges follow the framework notified by NPCI; the new P2M charges apply once the new charges start, which NPCI has postponed to after Diwali 2026. Net banking fees are agreed between the gateway and banks. A gateway may still add its own platform fee on either.
How much does the card type change the cost?
On a card-wise plan, the same ₹10,000 sale might cost ₹200 on a standard credit card, ₹250 on a premium card at an illustrative 2.5 percent, and ₹300 on an international card at an illustrative 3 percent. GST at 18 percent is then added to each. If a tenth of your card value moves from standard to premium cards, your blended rate rises even though your gateway has not changed its prices.
