India’s digital payments establishment spent six years telling merchants, banks, and fintech companies that free UPI was a feature, not a bug. On Tuesday, NPCI quietly retired that position.
From October 15, a Merchant Discount Rate — MDR — applies to select UPI Person-to-Merchant transactions. The payments industry has been lobbying for this for years. The government resisted, subsidised, and eventually ran out of road. Annual infrastructure costs for running UPI at its current scale are estimated at ₹20,000 crore. That number was always going to force a reckoning.
The fee structure — which most coverage has gotten partially wrong
The 0.4% MDR headline is accurate but incomplete. NPCI has built a tiered structure with meaningful carve-outs that significantly narrow the actual impact.
The 0.4% MDR applies to P2M UPI transactions above ₹2,000, capped at ₹300 per transaction for payments of ₹75,000 and above. Below ₹2,000, nothing changes. P2P transactions — sending money to friends, family, anyone — remain entirely free regardless of amount.
But the more interesting detail is what happens to essential sectors. Railways, telecom, insurance, fuel, and agricultural inputs — categories that account for nearly 17% of UPI P2M transaction volume but roughly 46% of merchant transaction value — will attract a flat MDR of just ₹5 per transaction above ₹2,000, rather than the percentage-based fee. Government utility bills — electricity, water, piped gas — and educational payments like school fees and university tuition above ₹2,000 get the same flat-fee treatment.
Payments into mutual funds, securities, and through stockbrokers will attract a lighter 0.02% MDR, also capped at ₹300.
Small merchants operating under the P2PM framework — those receiving up to ₹1 lakh per month through UPI QR payments directly into their bank accounts — continue to benefit from zero MDR.
UPI app providers are explicitly restricted from levying any platform fee on UPI transactions. That matters — it means the Paytms and PhonePes of the world cannot layer an additional charge on top.
Most transactions still not MDRed
About 96% of transactions remain outside the purview of MDR, with only 4-5% of large merchants impacted. A CareEdge Ratings report noted that P2M transactions constitute 29% of total UPI transaction value, with 67.2% of P2M transaction value exceeding ₹2,000 — implying that only about 19.5% of the value of overall UPI transactions potentially falls within the MDR threshold.
In other words: this is a surgical intervention, not a systemic overhaul. NPCI has structured the framework to touch large-ticket organised commerce while leaving the everyday economy — the chai stall, the auto-rickshaw, the kirana — completely untouched.
In terms of who gets most benefit, is where most debate is centered around in India at the moment. The conventional read is that PhonePe, Google Pay, and Paytm — the consumer-facing UPI apps — are the big winners. That is actually wrong.
Consumer-facing third-party apps, the UPI apps people use to pay, may not actually be the highest beneficiaries of the MDR. Enterprise-focused payment aggregators stand to benefit most directly, where the client base sits above the annual turnover threshold. Banks are also expected to see improved returns on the infrastructure they have been scaling under regulatory pressure.
The framework is well-designed for minimal disruption. The carve-outs are thoughtful, the thresholds are calibrated, and the small-merchant exemption is genuinely protective. On paper, NPCI has done the hard work of making this as painless as possible.
But the payments industry runs on behaviour, not policy documents. Whether large merchants absorb the MDR quietly, pass it on indirectly through pricing adjustments, or start nudging high-value customers toward alternative payment rails will only become clear in the weeks after October 15. That’s the data worth watching — not the announcement.
