A new 0.4% MDR applies to eligible UPI merchant payments above Rs. 2,000 from October 15, 2026, capped at Rs. 300 for transactions of Rs. 75,000 or more
Debit-card MDR is regulated and tiered by merchant type, while credit-card acceptance costs are set commercially and generally run higher, around 1.5% to 2.5% by industry estimates
RuPay credit cards linked to UPI follow a separate rulebook, so a payment made through a UPI app is not always a zero-cost UPI transaction
A UPI scan, a debit card tap, and a credit card swipe can look identical at checkout. The costs behind them are not. The real question is not what the customer pays. It is who pays the processing cost, how that cost is regulated, and whether the money comes from a bank account or a line of credit.
Merchants pay a processing charge called the Merchant Discount Rate, or MDR, on most card and digital payments. Banks, payment networks, and app providers usually split this fee among themselves.
MDR is mainly a merchant-side cost. It does not automatically show up as a fee for the customer. Whether a customer pays anything depends on the payment product, the transaction size, and the applicable rules. This distinction runs through the rest of the comparison.
UPI has run on a zero-MDR model for individual users since January 2020. Person-to-person transfers stay fully free, with no ceiling on the amount.
Merchant-side pricing is changing, though. NPCI has notified a 0.4% MDR on standard person-to-merchant transactions above Rs. 2,000, starting October 15, 2026. Payments of Rs. 75,000 or more carry a capped charge of Rs. 300.
A Rs. 50,000 payment attracts Rs. 200 in MDR. A Rs. 1 lakh payment stays capped at Rs. 300 rather than the Rs. 400 the flat rate would otherwise produce. Sectors such as railways, telecom, insurance, fuel and agriculture inputs attract a flat Rs. 5 charge instead.
Small merchants get separate protection. Under the Person-to-Person-Merchant framework, those receiving up to Rs. 1 lakh a month through UPI QR codes keep zero MDR on every transaction.
A merchant who crosses that limit for three straight months moves into the standard merchant category. NPCI expects the new MDR to touch only about 4% of merchant transactions, mostly larger payments. App providers cannot charge consumers a platform fee, and merchants cannot pass the MDR on to shoppers.
The reasoning is cost. NPCI recorded 24.51 billion UPI transactions worth Rs. 29.82 lakh crore in August 2026 alone. Running that scale takes steady spending on servers, fraud prevention and cybersecurity.
Debit-card MDR is not one flat figure. RBI's framework sets different caps by merchant category and acceptance method, with lower limits for small merchants and QR-based payments and higher limits for larger merchants using card machines or online checkout. Banks must ensure merchants do not pass this cost to customers separately.
RuPay debit cards have their own zero-MDR protection, with no monetary ceiling. This sits apart from the new Rs. 2,000 threshold now applying to UPI merchant payments, and the two frameworks should be read separately.
This tiered structure explains part of why debit cards and UPI have grown faster than credit cards for everyday, smaller purchases in India.
Credit-card acceptance costs run higher than regulated debit-card MDR, though no single official rate applies. Industry estimates put typical credit-card MDR around 1.5% to 2.5%.
The actual figure depends on the card network, merchant category, card type, and the specific agreement between merchant and bank, since credit-card MDR is set through commercial negotiation rather than a fixed cap.
This higher cost partly funds card rewards, cashback, and lounge access, alongside other sources such as interest and annual fees. It also shapes which payment methods some merchants prefer to promote.
Credit cards carry cost layers that UPI and debit cards skip: annual fees, finance charges on unpaid balances, late fees, cash-advance fees, and foreign-currency charges. A card can cost almost nothing for someone who clears the bill every month, but costs climb fast once a balance carries over.

A payment made through a UPI app is not always a zero-cost UPI transaction. NPCI lets eligible RuPay credit cards link to UPI apps for merchant payments, but the funding source stays the credit card, not a bank account. Small offline merchants get nil MDR on these transactions up to Rs. 2,000. Beyond that, standard credit-card rules apply.
The interface does not decide the economics. The source of funds does.
Judging these methods only by a visible customer fee misses the point. UPI keeps direct costs low on both sides, with a small, capped merchant charge above Rs. 2,000. Debit cards apply a regulated, tiered merchant cost while keeping the customer side simple. Credit cards add a lending relationship, which adds cost only if a balance carries over.
For daily purchases under Rs. 2,000, the method makes no difference to price. The gap shows up at scale, for merchants handling volume, and for larger purchases where MDR can shift pricing decisions.

Digital payments in India are moving past a simple free-or-paid label. The real difference lies in where the cost sits. UPI stays free for consumers, with a capped merchant charge above Rs. 2,000 from October 15. Debit cards run on regulated tiers, and credit cards mix processing cost with the economics of borrowing.
What matters next is not a fee on a customer's screen, but how merchants adjust which payment options they push forward.
1. Is UPI free for customers in India?
Yes. Eligible UPI payments do not carry a transaction fee for consumers. Under the new framework, specified merchant UPI payments above ₹2,000 will have a merchant-side MDR, but the cost cannot be passed on to the customer.
2. What is MDR in digital payments?
MDR, or Merchant Discount Rate, is a payment-processing charge paid by merchants for accepting certain digital payment methods. It is primarily a merchant-side cost and does not automatically mean the customer pays a separate fee.
3. Is credit card MDR higher than debit card MDR?
Generally, yes. Debit-card MDR is regulated under RBI rules, while credit-card MDR is largely determined through commercial arrangements. Industry estimates commonly place credit-card MDR above debit-card MDR.
4. Can a RuPay credit card be used through UPI?
Yes. Eligible RuPay credit cards can be linked to supported UPI apps for merchant payments. However, the payment is still funded by the credit card, so it follows credit-card rules rather than being treated exactly like a bank-account UPI payment.
5. Who pays the UPI MDR above ₹2,000?
The merchant pays the applicable MDR on eligible P2M UPI transactions above ₹2,000. The customer should not be charged a separate UPI transaction fee for this MDR.
