Starting October 15, certain Unified Payments Interface (UPI) transactions will incur a Merchant Discount Rate (MDR), introducing a new cost for businesses accepting digital payments. This new framework, established by the National Payments Corporation of India (NPCI), applies to Person-to-Merchant (P2M) UPI transactions exceeding ₹2,000. However, the charges for UPI cannot be directly compared to those for debit and credit cards, as each operates under distinct regulatory and commercial structures.
Understanding the New UPI MDR
Under the updated NPCI guidelines, a 0.4% MDR will be levied on eligible P2M UPI transactions where the value surpasses ₹2,000. This charge is capped at a maximum of ₹300 per transaction. It is crucial to note that this fee is borne by the merchant, while customers continue to enjoy fee-free UPI payments. Furthermore, person-to-person (P2P) UPI transfers remain exempt from this new MDR framework.
For instance, a merchant processing a ₹5,000 UPI payment would incur an MDR of ₹20. If the transaction value reaches ₹50,000, the charge would be ₹200. The ₹300 maximum cap becomes relevant for transactions valued at ₹75,000 or more.
Debit Card MDR: A Separate Structure
Merchant Discount Rates for debit card payments are governed by a separate framework established by the Reserve Bank of India (RBI). According to RBI rules from December 2017:
- For small merchants (with an annual turnover up to ₹20 lakh): The maximum MDR was set at 0.40% for physical point-of-sale (POS) and online card transactions, and 0.30% for QR-code-based card acceptance. These were subject to a ₹200 per-transaction cap.
- For other merchants: The corresponding ceilings were 0.90% for POS/online transactions and 0.80% for QR-code-based acceptance, with a higher cap of ₹1,000 per transaction.
While the new 0.4% UPI rate may overlap with some historical debit card MDR ceilings, their specific applicability, transaction thresholds, and maximum caps differ significantly, preventing a direct, apples-to-apples comparison.
Credit Card MDR: Commercial Arrangements Reign
Credit card payments operate under a distinctly different MDR model. Unlike UPI or debit cards, there is no single, RBI-prescribed MDR rate that applies across all credit card transactions. Instead, the cost for merchants accepting credit cards is determined by complex commercial arrangements. These involve multiple stakeholders, including card networks (e.g., Visa, Mastercard), card issuers (banks), acquirers, and various payment service providers.
Industry experts generally agree that, even with the new MDR, UPI remains a relatively more cost-effective payment acceptance method for merchants compared to many existing card-based systems. The introduction of MDR for higher-value UPI transactions marks a significant shift, providing a path towards more sustainable business models for payment ecosystem participants.
Impact on Merchants
For businesses, the key takeaway is that specified higher-value UPI transactions will now carry a defined acceptance cost. The actual financial impact will vary based on the merchant's category, typical transaction values, and the payment instruments customers choose to use.
