In August 2026 alone, UPI processed 24.51 billion transactions worth ₹29.82 lakh crore. That translates into an average of roughly 791 million transactions every day. The numbers are important not merely because they are large. They show how thoroughly digital payments have entered everyday economic life. A payment to a neighbourhood shop, a transfer between family members, a restaurant bill or a large merchant purchase can all move through the same underlying system. But infrastructure of this scale does not operate without cost. Behind the QR code are banks, payment service providers, application providers, servers, cybersecurity systems, fraud monitoring, settlement infrastructure, network resilience and continuous technological upgrades.
For years, the policy priority was adoption. Keeping UPI free helped create that adoption. The question India is now confronting is different: Can an infrastructure that has become essential to the economy continue to operate indefinitely without a sustainable economic model behind it? That is the question behind the new UPI framework.
What the New UPI Framework Actually Changes
The first thing to establish is what has not changed. UPI remains completely free for person-to-person transactions, regardless of the amount. Merchant payments up to ₹2,000 also remain free, while small merchants receiving up to ₹1 lakh a month through qualifying P2PM QR transactions continue under the zero-MDR framework. The government says approximately 96% of P2M transactions will remain unaffected. The new framework applies only to specified merchant transactions above ₹2,000. For these transactions, the MDR is 0.4%, with the charge capped at ₹300 per transaction for transactions of ₹75,000 and above. There are also special rates. Transactions above ₹2,000 in sectors including railways, telecommunications, insurance, fuel and agricultural inputs attract a flat ₹5 MDR. Payments relating to mutual funds, securities, stockbrokers and dealers attract 0.02%, capped at ₹300.
The distinction between MDR and a customer charge is crucial. The government says MDR is neither a tax nor money collected by the government or NPCI. It is distributed among participants in the payment ecosystem, including banks, payment service providers and UPI application providers. Banks have also been advised to ensure that merchants do not pass the MDR on to customers. So the debate should not be reduced to the idea that “UPI will now cost consumers 0.4%.” That is not what the framework says. The real change is that India is introducing a limited merchant-side economic model into a payment ecosystem that was deliberately kept largely free for years.
But What Does UPI Already Save India?
This is where the economics become more complicated. The cost of UPI cannot be examined in isolation from the costs of the system it increasingly complements or replaces. Cash also has an infrastructure. Currency has to be printed, stored, transported, distributed, counted, secured and eventually replaced. The Reserve Bank of India has explicitly recognised the significant cost of physical cash management.
In one RBI analysis, security-printing expenditure alone was ₹4,984.80 crore in 2021–22, up from ₹4,012.10 crore the previous year. The RBI has also noted that physical currency involves costs associated with printing, storage, transportation and replacement of banknotes, as well as settlement and reconciliation processes. That does not mean every rupee shifted from cash to UPI automatically creates a rupee of savings. India will continue to need physical currency, and cash infrastructure will remain necessary. But it does demonstrate something important: The alternative to digital payments is not costless. There are also less visible economic benefits.
Digital payments can reduce the amount of cash businesses need to handle, make reconciliation easier, speed up settlement and improve transaction transparency. The RBI has described digital payments as improving efficiency, reducing transaction costs and supporting financial inclusion and productivity. Then there is formalization. A digital transaction creates a record in a way that physical cash generally does not. As more economic activity moves through formal digital channels, the ability to document transactions and understand economic activity can improve. That can have implications for tax compliance and the formal economy. But this needs to be stated carefully.
It would be wrong to claim that every UPI transaction directly generates additional tax revenue. The fiscal benefit is broader: greater formalisation and visibility can potentially strengthen compliance and expand the taxable economic base. That means UPI has two sides to its balance sheet. On one side are the costs of building and maintaining the network. On the other are the costs it can reduce and the economic efficiencies it can create.
India’s UPI ecosystem has reached extraordinary scale. As a new merchant discount rate framework introduces charges on a limited category of larger transactions, the question is no longer whether UPI can transform payments, but how India should finance the infrastructure behind that transformation.

Ten years ago, UPI was an experiment in making digital payments simple, interoperable and accessible. Today, it is one of the most deeply embedded pieces of India’s economic infrastructure.
Can UPI Monetise Without Damaging What Made It Successful?
This is the most delicate part of the experiment. UPI became extraordinarily successful partly because it removed friction. A customer does not have to think about which bank the merchant uses. A small shop does not need an expensive card terminal. A transaction can be completed in seconds. That simplicity created a powerful network effect.
Introducing MDR therefore raises a legitimate economic question: how much cost can be introduced before that simplicity begins to lose some of its value?
The current framework attempts to address that by putting the burden on a relatively narrow segment. Ordinary P2P transactions remain free. Small merchant transactions remain protected. Payments below ₹2,000 remain free. The government says only about 4% of merchant transactions will actually attract MDR. That is a very different proposition from imposing a universal charge on UPI. There is also an important question about who ultimately absorbs the cost. Formally, MDR is paid within the merchant-payment ecosystem rather than by the customer.
But in any competitive market, the economic incidence of a cost can sometimes be distributed differently from the way the charge is formally imposed. A large retailer may absorb it. A payment provider may absorb part of it. A merchant may eventually incorporate some of the cost into pricing. Different businesses may respond differently. That is why the long-term question is not simply whether 0.4% is small. It is whether the system can introduce a sustainable revenue mechanism without weakening the low-cost, high-volume model that made UPI so successful in the first place.
The Bigger Question: Can India’s Digital Infrastructure Pay for Itself?
The UPI debate is ultimately larger than UPI. India has spent a decade building digital public infrastructure that has changed how citizens transact. The government has funded and supported the ecosystem while keeping everyday UPI usage free, helping it reach extraordinary scale. In August alone, the platform processed more than 24.5 billion transactions.
The next stage is therefore not simply about adding more transactions. It is about building an economic model capable of supporting the infrastructure behind them. That model has to account for several things simultaneously: What UPI costs to operate. What merchants and financial institutions gain from it. What the economy saves through reduced cash handling and greater transaction efficiency. What greater formalisation can contribute to the wider economy. And increasingly, there is another dimension: India is taking UPI beyond its borders. The system is now accepted in 11 countries, and policymakers are actively pursuing further international integration. The objective, therefore, cannot simply be to collect enough MDR to pay an infrastructure bill. It is to create a system in which the enormous economic value generated by digital payments helps sustain the infrastructure that generates that value.
The Centre’s View
UPI does not necessarily need to remain completely free for every participant forever to remain a public success. But neither should sustainability be measured only by how much money can be extracted from the payment system. The larger calculation includes the cost of maintaining UPI, the costs avoided through reduced dependence on physical cash, the efficiency created for businesses and consumers, and the broader economic value of formal digital transactions.
India's challenge is to find the point at which these pieces work together. The new MDR framework is therefore more than a decision about payment charges. It is an early test of a much bigger proposition: Can India build digital infrastructure at national scale, make it accessible to hundreds of millions of people, and eventually create an economic model capable of sustaining that infrastructure without undermining the very accessibility that made it successful? That may be the real next chapter of India's UPI revolution.
