What Exactly is Changing with UPI?
The era of universally free Unified Payments Interface (UPI) transactions for merchants is ending. Starting October 15, 2026, the National Payments Corporation of India (NPCI) will introduce a Merchant Discount Rate (MDR) on certain transactions. Specifically,
a 0.4% charge will apply to person-to-merchant (P2M) payments that are over ₹2,000. This means for a ₹3,000 transaction, a merchant would pay ₹12. For very large transactions of ₹75,000 or more, this fee is capped at a maximum of ₹300. Crucially, these charges are meant to be paid by the merchant, not the customer, and the government has explicitly stated that merchants are prohibited from passing this cost on. Person-to-person (P2P) transfers remain completely free, regardless of the amount.
Why Now? The Rationale Behind the Move
The introduction of MDR is a strategic move to ensure the long-term financial sustainability of the UPI ecosystem. Processing billions of transactions monthly requires immense investment in infrastructure, technology, and cybersecurity. Until now, the costs have been largely absorbed by banks and payment service providers, supported by government incentives. The new MDR is not a government tax; it's a fee that gets distributed among the players in the ecosystem—banks, payment apps, and other service providers—to help them cover their operational costs and continue to innovate. The Reserve Bank of India has supported the move, stating it will help UPI scale, innovate, and serve the country better.
The Festive Season Magnifies the Impact
The timing of this change, right before the peak festive shopping season of Dussehra and Diwali, is critical. This period sees a massive surge in consumer spending and transaction volumes across the country. For merchants, particularly those dealing in higher-value goods like electronics, apparel, and jewellery, the new MDR could significantly impact their profit margins. While a 0.4% fee may seem small on a single transaction, it can add up to a substantial amount over the high-volume festive period. This change forces businesses to re-evaluate their payment acceptance strategies and financial planning at the busiest time of the year.
Relief for Small Merchants and Essential Services
The new rules include important exemptions designed to protect small businesses and ensure affordability for essential payments. Small merchants who receive up to ₹1 lakh per month via UPI QR codes will not have to pay any MDR, regardless of transaction size. This ensures that the kirana stores and street vendors who form the backbone of India's retail landscape are not burdened. Furthermore, transactions of any amount up to ₹2,000 remain completely free for all merchants, which NPCI notes covers over 95% of all UPI merchant transactions by volume. Additionally, essential services like railways, telecom, insurance, fuel, and utility bill payments will have a lower, flat MDR of just ₹5 for transactions over ₹2,000, ensuring cost stability in critical sectors.
Will This Push Merchants Back to Cash?
A key concern is whether this new cost will deter merchants from accepting UPI for larger payments, potentially leading to a resurgence of cash. Some analysts worry that businesses might try to split larger bills into multiple smaller transactions to avoid the fee, or worse, unofficially pass the cost to consumers. However, RBI officials have expressed confidence that this is unlikely to happen, suggesting any apprehension will be temporary. The convenience, security, and efficiency of UPI are powerful incentives. Furthermore, the new UPI MDR is still significantly lower than the fees for credit cards, which typically range from 1.5% to 2.5%. The framework attempts to strike a balance, making the system financially viable without reversing its widespread adoption.
