A proposed UPI MDR framework is exposing a tension at the heart of India’s digital payments system: the same transaction channel that reduces cash handling and simplifies commerce could become materially more expensive for businesses operating on narrow margins. A report by Aaj Tak Business says eligible person-to-merchant UPI transactions above ₹2,000 may attract a 0.4% merchant discount rate, subject to a maximum charge of ₹300, while several categories of smaller or exempt transactions would remain outside the levy.
The immediate concern comes from businesses that process large payment volumes but retain relatively little profit from each sale. Rahul Mammen, director of MPC Pharma Private Limited, said in a LinkedIn post cited by the report that his company manages about ₹1 crore in UPI payments each day. At a 0.4% charge, he estimated a daily cost of about ₹40,000 and an annual impact of nearly ₹1.2 crore. He said the company could consider limiting UPI acceptance for large-value payments if the additional cost makes the channel unprofitable.
That calculation is not a projection for the entire pharmaceutical sector. It is a company-level estimate based on the transaction volume described by Mammen. But it demonstrates why MDR is particularly sensitive for businesses whose gross margins are only 2% to 3%. A payment charge that appears small when expressed as a percentage of the transaction can consume a much larger share of the profit generated by that transaction.
The calculation shared by chartered accountant Kanan Bahl, and reproduced in the report, puts the possible effect in those terms. At a 0.4% MDR, a business with a 2% margin would see the charge absorb roughly one-fifth of that margin before other operating costs are considered. For a business with a 3% margin, the proportion would be lower, but still significant. The report describes this as an 11% to 17% impact on gross profits for businesses operating within that margin range.
This is the central institutional issue behind the UPI MDR debate. Merchant payment systems are not only technology networks; they are also cost-allocation systems. Every payment has to be processed, routed and settled, and the question is who bears that cost. When a payment channel is free to the merchant, the cost has to be absorbed or compensated elsewhere. When a charge is introduced, even at a low rate, the effect varies sharply between a high-margin retailer and a low-margin distributor.
For urban commerce, the distinction matters because digital payments are embedded across very different kinds of businesses. A large chain, a neighbourhood pharmacy, a distributor and a service provider may all accept UPI, but their operating structures are not interchangeable. A charge linked to transaction value can therefore have a different effect depending on inventory costs, working capital, rent, staffing and the margin retained on each sale. The supplied report does not provide a sector-wide assessment, but the pharmaceutical example illustrates this uneven exposure.
The reported framework also contains thresholds intended to protect smaller merchants. According to Aaj Tak Business, the proposed 0.4% MDR would apply to eligible person-to-merchant UPI transactions above ₹2,000, with the total charge capped at ₹300. Transactions below that threshold would not attract the charge. The report further says that merchants receiving up to ₹1 lakh per month through a UPI QR code would not have to pay MDR, regardless of the individual transaction amount.
These provisions create a tiered system rather than a universal charge on every UPI payment. The report says the arrangement would exclude 96% of merchants. That figure is presented as part of the reported framework, but the article does not identify the underlying official document or explain how the merchant universe was calculated. The distinction is important: the number of merchants exempted does not necessarily indicate the share of transaction value that would be exempted. A small group of high-volume merchants could account for a substantial portion of payment flows.
The thresholds also underline the difference between protecting access and protecting business economics. A merchant may fall outside the MDR because of monthly QR receipts while a higher-volume business may face charges even if its individual margins are thin. In other words, the framework appears designed to shield the smallest participants, but the cost pressure may be concentrated among businesses that process larger payments or operate at scale.
The reported exemptions and reduced rates add another layer. Railways, telecommunications, insurance and fuel transactions are described as being subject to a flat ₹5 rate rather than the 0.4% MDR. Payments linked to mutual funds, brokers and equities are reported to attract a lower 0.02% MDR, subject to the ₹300 cap. These classifications suggest that the framework differentiates between sectors instead of treating all person-to-merchant payments identically.
Such differentiation makes the administrative design of the system important. Merchants and payment service providers would need to know which transactions qualify, how the thresholds are calculated, when the charge is settled and whether the burden is absorbed by the merchant or passed through the payment chain. The supplied report does not establish those operational details or specify the implementation date. It also does not identify the formal notification, circular or decision through which the revised framework was announced.
That absence does not remove the commercial significance of the issue, but it limits what can be concluded. The ₹1.2 crore estimate is an individual company’s calculation, not evidence that every low-margin business will face the same annual cost. Similarly, the reported 96% exemption figure cannot by itself show how many high-volume merchants will be affected or what proportion of total UPI value would attract MDR.
The institutional response is also still part of the story. Mammen has asked the National Payments Corporation of India to reconsider the proposed rule. NPCI is identified in the report as the body to which the request was made, but the supplied material does not include a response from NPCI, a government statement or a formal clarification from banks and payment companies. That means the debate, as currently documented, is being driven by an affected business representative and a professional commentator rather than by a complete public explanation of the policy framework.
The issue therefore reaches beyond a single payment charge. It tests whether India’s digital payment infrastructure can remain broadly accessible while its operating costs are allocated in a way that does not disproportionately strain low-margin commerce. A free payment channel encourages adoption, reduces reliance on cash and can simplify records. A charge may alter those incentives for businesses that cannot absorb even a fraction of a percentage point without affecting their margins.
For customers, the immediate effect is not established in the supplied report. Businesses could absorb the cost, renegotiate payment arrangements or alter the payment methods they encourage. Mammen’s statement indicates that at least one company is considering limiting UPI acceptance for large-value payments, but it does not confirm that the company has implemented such a change. Whether other merchants respond similarly would depend on their margins, payment mix and ability to shift customers towards NEFT, cash or cheques.
The reported framework also raises a measurement question. Assessing the success of the policy would require more than counting exempt merchants. It would require tracking the value and number of affected transactions, the distribution of MDR across sectors, changes in merchant acceptance and the effect on businesses with narrow margins. None of those outcomes is available in the supplied material, so they remain matters for subsequent reporting rather than established consequences.
What the evidence currently confirms is narrower but still significant. A pharma company director has calculated a potential annual cost of ₹1.2 crore based on about ₹1 crore in daily UPI payments and a proposed 0.4% charge. The reported framework includes thresholds, a ₹300 cap, a monthly QR exemption and sector-specific rates. It also creates a clear concern for businesses whose margins are only 2% to 3%.
The next stage of the debate will depend on formal policy documentation and responses from NPCI and other relevant payment-system institutions. Until those details are available, the central question is not whether UPI MDR will affect every merchant equally, but how the framework will distribute costs across the businesses that have come to depend on digital payments most heavily.
