India’s digital payment backbone is undergoing a major structural shift with the formal reintroduction of the Merchant Discount Rate (MDR) on selected Person-to-Merchant (P2M) Unified Payments Interface (UPI) transactions. While UPI remains free for consumers and small vendors, mid-sized and large merchants must now factor processing fees into higher-value digital sales.
What Is MDR on UPI?
Merchant Discount Rate is the fee a merchant pays to acquiring banks, payment aggregators, and the National Payments Corporation of India (NPCI) for processing digital payments.
For years, UPI operated under a zero-MDR mandate funded largely via government subsidies. The updated framework reintroduces a percentage-based fee on transactions above specific thresholds to make digital payment infrastructure, server bandwidth, and fraud prevention financially self-sustaining.
Who Pays and What Is Exempt?
Consumers Pay ₹0: Peer-to-peer (P2P) transfers (splitting dinner, sending money to family) and regular customer-side retail payments remain completely free. Merchants are legally prohibited from passing this fee as an added surcharge.
Small Merchants (P2PM) Exempt: Small vendors and micro-merchants receiving up to ₹1,00,000 per month via static QR codes remain exempt.
The ₹2,000 Floor: Transactions valued at ₹2,000 or below carry 0% MDR. This covers over 95% of daily retail UPI volume.
AutoPay / Mandates: Standing automated instructions (such as OTT subscriptions, utility bill debits, and regular mutual fund SIPs) do not attract standard P2M MDR.
How Is the Charge Calculated?
For standard P2M transactions exceeding ₹2,000, MDR is levied at a base uniform rate of 0.4% on the gross transaction value (subject to specific sector caps or lower rates for segments like capital markets).
| Transaction Value | Base MDR Rate | MDR Amount | GST (18% on MDR) | Total Deduction | Net Merchant Settlement.
- | ₹1,500 | 0.0% (Exempt) | ₹0.00 | ₹0.00 | ₹0.00 | ₹1,500.00 |
- | ₹2,000 | 0.0% (Threshold) | ₹0.00 | ₹0.00 | ₹0.00 | ₹2,000.00 |
- | ₹3,500 | 0.4% | ₹14.00 | ₹2.52 | ₹16.52 | ₹3,483.48 |
- | ₹10,000 | 0.4% | ₹40.00 | ₹7.20 | ₹47.20 | ₹9,952.80 |
- | ₹50,000 | 0.4% | ₹200.00 | ₹36.00 | ₹236.00 | ₹49,764.00 |
Where Does the Collected MDR Go?
The fee collected from the merchant does not sit with a single entity. It is split across the payment chain:
Remitter Bank (Issuer): Receives the interchange portion to cover core banking infrastructure and account security.
Acquirer / Payment App: Platforms like Paytm, PhonePe, Google Pay, or PoS providers receive acquiring fees for hardware, software integrations, and merchant servicing.
NPCI: Retains a switching fee to route messages and maintain the central switch.
At 0.4%, UPI's MDR remains significantly cheaper than traditional credit cards (typically 1.5% to 2.5%), striking a balance between financial sustainability for payment companies and low-friction acceptance for Indian commerce.
