Decoding the Rs 40 on Rs 10,000
The figure in the headline is not a random number; it is a direct calculation based on the new rules. Effective October 15, 2026, the National Payments Corporation of India (NPCI) has introduced a Merchant Discount Rate (MDR) of 0.4% on certain UPI transactions.
So, for a Rs 10,000 payment made to a merchant via UPI, the fee would be exactly Rs 40. This MDR is a fee that merchants pay to their bank and payment service provider for the service of processing a digital transaction. It’s a standard practice for credit and debit cards, but its arrival in the UPI world marks a major turning point for the ecosystem that has operated on a zero-fee model for merchants since 2020.
Why Change a Winning Formula?
The zero-MDR regime was a government mandate designed to turbocharge digital payment adoption across the country, and it worked spectacularly. So why introduce a fee now? The answer is sustainability. While UPI is free for users and has been for merchants, it is not free to operate. Banks, payment apps, and other service providers in the ecosystem bear significant costs for maintaining the massive infrastructure, ensuring cybersecurity, and investing in innovation. The Reserve Bank of India (RBI) has backed the move, stating that a fairly distributed MDR is crucial for the long-term health and scalability of the UPI network. Without a revenue stream, the very players supporting UPI's growth were facing financial strain, making the system unsustainable in the long run.
How the New MDR System Works
This new charge is not a blanket fee on all UPI payments. The rules are specific and designed to protect small-value transactions and small businesses. The 0.4% MDR applies only to person-to-merchant (P2M) payments with a value greater than Rs 2,000. Any payment you make to a friend or family member, regardless of the amount, remains completely free. Furthermore, all merchant transactions below the Rs 2,000 threshold are also exempt. This means the vast majority of daily UPI transactions, which are small-ticket purchases, will not be affected. For very large payments, the fee is capped at Rs 300 per transaction, which applies to payments of Rs 75,000 and above.
Who Really Pays the Price?
Officially, the MDR is to be paid by the merchant. The government and Finance Minister Nirmala Sitharaman have been clear that this charge should not be passed on to the consumer. Banks have been advised to ensure merchants comply. However, industry bodies like the Retailers Association of India have raised concerns. They argue that businesses operating on wafer-thin margins, such as mobile phone retailers, will feel the squeeze. The All India Mobile Retailers Association pointed out that a 0.4% charge could wipe out a significant portion of their net margins, which often hover between 0.75% and 1.5%. The fear is that this could either lead to merchants discreetly raising prices or, in some cases, reverting to cash to avoid the fee.
Exemptions for Small Merchants
To soften the blow on the smallest players, the framework includes an important exemption. Small vendors who receive up to Rs 1 lakh per month through UPI are not required to pay the MDR, even on transactions above Rs 2,000. While this protects millions of micro-entrepreneurs, it also raises questions about implementation. Critics have pointed out the potential compliance burden of tracking monthly turnover and determining when a merchant crosses the threshold, which could create confusion in the short term. Despite these concerns, the introduction of MDR is seen by many in the financial sector as a necessary step to mature the UPI ecosystem from a government-subsidized utility into a self-reliant financial infrastructure.
