The National Payments Corporation of India (NPCI) is looking at a new Merchant Discount Rate (MDR) for UPI. MDR is a small fee that shopkeepers pay to the bank for processing digital payments. The goal is to make the UPI system self-sustaining, meaning it can pay for its own costs without needing government help. This plan ensures that regular people like you and me do not pay extra for our daily tea or grocery shopping.

For most big shopkeepers, transactions over ₹2,000 will have a 0.4% fee. This fee is capped at ₹300 per transaction, so the bank cannot charge more than that even for very expensive items. This is much cheaper than the fees usually charged on credit cards. For some specific services, the fee is even lower. Payments for railway tickets, insurance, electricity bills, water bills, and school fees will only cost the merchant a flat ₹5 if the bill is over ₹2,000.

Stock market investors and mutual fund users also get a big break. The fee for payments to stockbrokers or mutual funds is set at just 0.02% of the total amount. Like other categories, this is also capped at ₹300. This keeps the cost of investing low for the common man while still providing some income to the banks managing the money transfer.

Small merchants are the backbone of India, and they are protected under this new rule. If a shopkeeper receives less than ₹1 lakh per month through their UPI QR code, they are in a special 'P2PM' (Person-to-Person-Merchant) group. These small shopkeepers do not have to pay any MDR at all. There is even a plan to create a special fund to help support these small businesses using money collected from the bigger merchants.

However, there is a rule for growth. If a small merchant starts earning more than ₹1 lakh per month for three months in a row, they will move to the regular merchant category. Once they move, they will have to start paying the 0.4% fee on transactions over ₹2,000. This ensures that only truly small businesses get the tax-free benefit.

It is important for bank staff to explain to customers that this MDR does not apply to regular money transfers between friends or family. Transfers using IMPS, NEFT, or RTGS are also not affected by these rules. Also, these specific rules are for UPI linked to bank accounts. UPI linked to RuPay credit cards follows different rules that already exist for the credit card industry.

The potential for revenue is massive. In August 2026, total UPI transaction values hit ₹298 lakh crore. About 20% of these were merchant payments over ₹2,000. If we apply the fee to these transactions, the system could collect around ₹2,400 crore in just one month. This money will help banks improve their technology and security for all users.

Bankers should watch for official circulars on when these exact rates will be implemented. As UPI grows, these collections will help banks manage the high cost of maintaining the digital payment infrastructure. For now, the focus remains on keeping the system free for consumers while asking larger businesses to contribute their fair share.
