What is MDR and How is UPI Changing?
Merchant Discount Rate, or MDR, is a fee that businesses pay to banks and payment service providers for processing digital transactions. For years, UPI transactions for merchants were free of this charge, a policy that massively boosted its adoption.
Now, the National Payments Corporation of India (NPCI) is introducing a change. Starting October 15, 2026, a 0.4% MDR will apply to person-to-merchant (P2M) UPI payments above ₹2,000. This move ends the zero-MDR regime that has been in place since 2020. However, this isn't a blanket fee. Person-to-person (P2P) transfers, like sending money to a friend, remain free, and crucially, so do all merchant payments up to ₹2,000.
The New Rules Explained
The new structure is tiered. For a standard merchant transaction above ₹2,000, the fee is 0.4%. For example, on a payment of ₹3,000, a merchant would incur a charge of ₹12. To prevent excessive charges on very large purchases, the MDR is capped at ₹300 for any single transaction of ₹75,000 or more. The NPCI has clarified that consumers will not be charged for making UPI payments. The fee is to be borne by the merchant. Furthermore, exemptions are in place for small vendors. Merchants receiving up to ₹1 lakh per month via UPI are exempt from MDR, a measure intended to protect the smallest businesses. The government estimates that over 95% of all merchant UPI transactions will remain free under this new framework.
Why is This Happening Now?
The introduction of MDR is driven by the need for long-term sustainability. Running the massive UPI infrastructure—which processed over 24 billion transactions in August 2026 alone—involves significant costs for banks and payment companies for servers, cybersecurity, and maintenance. For years, industry bodies have argued that the zero-MDR policy was unsustainable without a direct revenue stream. The new fee structure is designed to create a viable economic model that allows the ecosystem to invest in technology and security, ensuring UPI remains robust. The revenue will be distributed among the ecosystem players, including banks and payment apps, that facilitate the transactions.
Impact on Merchants This Festive Season
The timing of the change, just before the peak Diwali shopping period, has caused concern among retailers. The festive season is when many merchants, from electronics stores to apparel retailers, see their highest sales volumes, often with individual transaction values exceeding ₹2,000. The Retailers Association of India (RAI) has warned that this new cost will squeeze the margins of businesses already dealing with other economic pressures. For a retailer with a net profit of 3%, a 0.4% MDR could wipe out a significant portion of their earnings on those sales. While large retail chains may absorb the cost to retain customers, smaller merchants could be hit harder. There are concerns that some may be tempted to prefer cash for larger transactions to avoid the fee.
Will Shoppers Feel the Pinch?
Officially, consumers are not supposed to pay the MDR. The NPCI has explicitly prohibited merchants from passing this cost directly on to customers at the checkout. However, the indirect impact is less certain. While large retailers are unlikely to add a surcharge, there is a possibility that some smaller businesses might try to do so, or that the cost gets factored into product pricing over time. Some merchants might also encourage customers to split a large bill into multiple payments of less than ₹2,000 to avoid the charge, as there is currently no daily cap on such transactions to the same merchant. For now, shoppers should not expect to pay extra for using UPI, but they may notice merchants adjusting their payment preferences for higher-value purchases.
