For years, Unified Payments Interface (UPI) has been one of the clearest examples of how India can build a digital public infrastructure at massive scale. From buying groceries at a neighbourhood kirana store to paying utility bills, splitting a restaurant bill or making a large purchase, UPI has made instant bank-to-bank payments almost as simple as handing over cash. But that model is now entering a new phase.

The National Payments Corporation of India (NPCI) has announced a new Merchant Discount Rate (MDR) of 0.4% on specified UPI person-to-merchant transactions above ₹2,000, effective October 15, 2026. The charge will be capped at ₹300 for transactions of ₹75,000 and above. Importantly, consumers will not directly pay this MDR, while person-to-person transactions will continue to remain free. UPI payments to merchants up to ₹2,000 will also remain free, meaning around 96% of P2M transactions are expected to remain unaffected.

The change marks a major shift for a payment system that has operated largely without a merchant transaction fee for more than six years. It also raises a bigger question: Can UPI remain affordable, inclusive and ubiquitous while creating a sustainable revenue model for the companies and banks that operate the ecosystem?

The answer will matter not only to payment apps and banks but also to millions of merchants, consumers and businesses that have made UPI a part of everyday economic activity.

UPI Has Become the Backbone of India’s Digital Payments

The scale of UPI today is difficult to compare with most other payment systems globally. According to NPCI data, UPI processed 24.51 billion transactions worth ₹29.82 trillion in August 2026, marking a record in transaction volume. That works out to roughly 791 million transactions every day. Transaction volume increased about 22% year-on-year, demonstrating how deeply UPI has become embedded in India’s payment behaviour.

The growth has also changed the nature of India’s payments market. UPI is no longer limited to urban consumers using smartphones. QR codes can be found at small shops, street stalls, taxis, restaurants, pharmacies and service businesses across the country.

This widespread adoption was helped by an important feature: UPI was effectively free for consumers and merchants for everyday transactions. Instead of charging merchants directly, the government supported the ecosystem through incentives, while banks, payment apps and payment service providers absorbed or recovered costs through other parts of their businesses.

That model helped UPI achieve scale. The introduction of MDR therefore represents more than a simple change in pricing. It raises questions about how India’s digital payments infrastructure should be financed as it becomes increasingly important to the economy.

What Is Changing From October 15?

The new framework does not mean that consumers will suddenly be charged for every UPI payment. The distinction between P2P and P2M transactions is crucial.

Person-to-Person Payments

Money transferred from one individual to another will remain completely free, regardless of the transaction amount. So, sending ₹5,000 to a family member or ₹50,000 to a friend will not attract the new MDR.

Merchant Payments Up to ₹2,000

UPI payments of up to ₹2,000 to merchants will also remain free. This is particularly important for small-ticket transactions such as groceries, food, local transportation and everyday purchases.

Merchant Payments Above ₹2,000

Specified P2M transactions above ₹2,000 will attract a 0.4% MDR. For example, a ₹5,000 eligible merchant payment would generate an MDR of ₹20. A ₹20,000 transaction would generate ₹80, while a ₹75,000 transaction would hit the ₹300 cap. For transactions of ₹75,000 or more, the MDR is capped at ₹300.

There are also different rates for certain categories. For example, payments involving sectors such as railways, telecom and fuel will attract a flat ₹5 fee, while capital-market transactions have a lower rate of 0.02%, according to published details of the new framework.

Who Actually Pays the UPI Fee?

This is one of the most important aspects of the new system. The 0.4% MDR is a merchant-side fee rather than a direct consumer charge. The government has clarified that MDR is neither a tax nor a fee collected by the government or NPCI. Instead, it is distributed among participants in the payment ecosystem, including banks and payment application providers.

In simple terms, if an eligible customer makes a ₹10,000 UPI payment to a merchant, the consumer pays ₹10,000. The merchant receives the amount after applicable charges are accounted for.

The revenue is then distributed among the different entities involved in processing the payment. This distinction is important because the objective is to introduce a revenue stream for the payments ecosystem without directly discouraging consumers from using UPI.

Why Is UPI Introducing MDR Now?

The fundamental argument behind the change is sustainability. UPI handles billions of transactions every month, requiring enormous investment in technology infrastructure, cybersecurity, fraud detection, network reliability and customer support. As the system grows, these costs also increase.

Industry participants have argued that a sustainable revenue model is necessary if UPI is expected to continue scaling safely. Reuters reported that the new framework is intended to support investment in infrastructure resilience, innovation, cybersecurity and customer service.

The issue has become more important as UPI moves from being a relatively new payment system to a critical part of India’s financial infrastructure.

A payment platform that processes hundreds of millions of transactions every day cannot afford prolonged underinvestment in cybersecurity or reliability.

The introduction of MDR therefore attempts to answer a difficult question: Who should ultimately pay for maintaining and expanding the infrastructure behind free digital payments?

The ₹15,000 Crore Question

The financial scale of the new framework could be significant. According to The Indian Express, the revised MDR structure could generate approximately ₹15,000 crore in annual receipts. The money would be distributed among banks, payment applications and other participants in the payments ecosystem.

For perspective, the government had already spent ₹8,730 crore between FY22 and FY25 under its incentive scheme supporting UPI payments. The earlier model effectively used public support to encourage payment companies and banks to keep UPI free.

The new MDR framework therefore represents a move from a model heavily dependent on incentives toward a system where at least some transaction activity generates revenue within the ecosystem.

Whether ₹15,000 crore ultimately becomes the actual annual revenue will depend on transaction mix, merchant behaviour and how businesses respond to the new charges.

Will Merchants Move Away From UPI?

This is one of the biggest concerns surrounding the change. For a large retailer processing millions of rupees in UPI payments, even a 0.4% fee can become a meaningful operating expense.

Consider a merchant processing ₹10 lakh in eligible UPI transactions above the threshold. A 0.4% MDR would translate to approximately ₹4,000 in fees before considering the transaction cap and applicable category-specific rules. For businesses operating on thin margins, these costs can matter.

However, UPI’s convenience creates a powerful counterargument. Consumers have become accustomed to scanning a QR code and completing a payment within seconds. Businesses may therefore be reluctant to remove UPI as a payment option even if it becomes slightly more expensive.

The bigger question is whether merchants absorb the cost or attempt to recover it indirectly through pricing.

The current framework does not allow the consumer to be directly charged the MDR simply because the merchant accepts UPI. But businesses could potentially reconsider discounts, payment incentives or pricing strategies to compensate for higher payment-processing costs.

Could This Change Consumer Behaviour?

For most consumers, the immediate impact is likely to be limited because payments up to ₹2,000 remain free and P2P transactions remain free.

This is important because everyday UPI usage is dominated by small-value transactions.

The government’s FAQ says around 96% of P2M transactions will remain unaffected by the new framework.

That means the customer buying a ₹300 meal, paying ₹800 at a grocery store or sending money to a friend should continue using UPI without a transaction fee. The greater impact will be on larger merchant purchases.

A customer buying an expensive electronic item, paying a large bill or making another high-value merchant payment could still use UPI, but the economics for the merchant will change.

The Bigger Concern: Could UPI Become Less Inclusive?

The success of UPI has partly come from its simplicity. There is no need to understand MDR, card networks, transaction fees or payment gateways. A customer simply scans a QR code and pays.

Introducing a fee into the ecosystem could make merchant acceptance more complicated, particularly for smaller businesses. However, the decision to retain the ₹2,000 exemption is clearly designed to protect small-value commerce.

This creates an interesting balance: large transactions generate revenue while everyday small payments remain effectively free. The success of this approach will depend on whether merchants continue to view UPI as sufficiently valuable to absorb the cost.

The Competitive Impact on PhonePe, Google Pay and Other Apps

The change could also reshape India’s digital payments industry. UPI is dominated by a handful of major applications, particularly PhonePe and Google Pay. Reuters reported that the two together account for around 80% of the UPI transaction market.

The introduction of MDR could therefore create a substantial new revenue opportunity for large payment platforms. Reuters estimates that the broader fee pool could potentially reach around $1.1 billion by March 2028, with dominant platforms potentially capturing a significant portion.

This could give major players additional resources to invest in merchant acquisition, financial products, technology and rural expansion.

At the same time, it raises concerns about market concentration. If large platforms become significantly more profitable from UPI, smaller competitors may find it harder to compete.

This is particularly relevant because NPCI has previously considered a 30% market-share cap for individual UPI apps, but implementation has been delayed.

What Does It Mean for Banks and Fintech Companies?

Banks are likely to become important beneficiaries because they sit at the core of the UPI infrastructure. The new revenue stream could strengthen the economics of transaction banking while helping institutions fund technology and cybersecurity investments.

Payment companies could also benefit by monetising transaction activity that previously generated limited direct revenue.

The change could be particularly relevant for listed fintech and payments businesses. Pine Labs, for example, saw its stock rise around 5% on September 17 as investors assessed the potential earnings benefits of the new UPI MDR framework.

For investors, however, the actual financial impact will depend on transaction mix, market share, revenue-sharing arrangements and the ability of companies to convert UPI activity into sustainable profits.

Could the Fee Undermine UPI’s Original Advantage?

This is perhaps the most important long-term question. UPI’s competitive advantage has been its combination of low cost, instant settlement, interoperability and ease of use.

Introducing MDR does not fundamentally destroy that model because the fee is relatively low compared with many traditional card-payment costs. Government FAQs indicate that the baseline UPI MDR of 0.4% is below typical credit-card MDRs, which can be around 1.5% to 2.5%.

Still, the psychological impact of moving from “free” to “not always free” should not be underestimated. The challenge for policymakers is therefore to ensure that monetisation does not discourage merchants from accepting UPI or encourage consumers to return to cash.

A New Phase for India’s UPI Revolution

The introduction of MDR represents a significant evolution in India’s digital payments journey.

UPI’s first phase was about adoption. The objective was to convince consumers and businesses to move from cash and fragmented payment methods to a common digital infrastructure.

The second phase was about scale. UPI expanded rapidly until it became one of the world’s largest real-time payment systems. The next phase may be about sustainability and monetisation.

The numbers show how far UPI has come. In August 2026 alone, the platform processed 24.51 billion transactions worth ₹29.82 trillion. The challenge now is ensuring that such enormous scale can be maintained while paying for cybersecurity, infrastructure, innovation and customer service. The new MDR framework is an attempt to address that challenge.

Conclusion

The introduction of a 0.4% MDR on specified UPI merchant transactions above ₹2,000 from October 15, 2026 marks the end of an important chapter in India’s digital payments story. But it does not mean UPI is suddenly becoming a paid service for consumers.

Person-to-person payments remain free, merchant payments up to ₹2,000 remain free, and around 96% of P2M transactions are expected to remain unaffected.

The real change is economic rather than consumer-facing. Banks, payment apps and other participants will finally have a larger transaction-linked revenue stream to support the infrastructure behind UPI.

For merchants, the calculation will be different. Large businesses will have to factor MDR into their payment costs, while small merchants are largely protected by the exemption. For fintech companies and banks, meanwhile, the new framework could create a significant source of revenue.

The bigger test will be whether India can monetise UPI without weakening the very characteristics that made it successful: affordability, convenience, interoperability and mass adoption.

If managed carefully, the fee could provide UPI with the financial foundation needed for its next phase of growth. If costs eventually become too burdensome for merchants, however, the system could face pressure to rethink how digital payments are funded.

Either way, India’s UPI revolution has entered a new chapter: from building a free digital payments network to building a financially sustainable one.
