Explained: How UPI’s new MDR changes the economics of India’s favourite payment habit 

Article Summary 

• From October 15, UPI payments above ₹2,000 made to eligible merchants will attract a 0.4% Merchant Discount Rate, capped at ₹300 per transaction. Customers will not be charged directly. 

• Person-to-person UPI payments remain completely free, regardless of the amount transferred. Payments of up to ₹2,000 to merchants also remain free, as do payments received by eligible small merchants. 

• The bigger question is what happens beyond the transaction itself: whether merchants absorb the cost, adjust prices, or increasingly encourage other payment methods. 

• Entrepreneur Ashneer Grover argues that India should look at the economics of UPI and cash together before deciding that digital payments need to be monetised. 

For years, UPI has quietly changed one of the most mundane parts of Indian life: paying for things. A vegetable vendor flashes a QR code. A restaurant sends the bill. A friend asks you to split dinner. A child needs money. A driver needs to be paid. You scan, enter the PIN, and move on. There is almost no friction, and, importantly, almost no visible cost. 

That changes, at least at the merchant end, from October 15. 

The National Payments Corporation of India (NPCI) has introduced a 0.4% Merchant Discount Rate, or MDR, on specified person-to-merchant UPI transactions above ₹2,000. The charge will be capped at ₹300 for transactions of ₹75,000 and above. Certain sectors, including railways, telecom, insurance, fuel, and agricultural inputs, will instead pay a flat ₹5 for transactions above ₹2,000. 

The first thing consumers need to know is simple: you are not being charged for using UPI. At least on paper. 

If you pay a shop ₹5,000 through UPI, the transaction will still debit your account by ₹5,000. The MDR is supposed to be charged within the merchant payment ecosystem, rather than added to your bill. Banks have also been advised to ensure merchants do not pass the charge on to customers, but you and I both know exactly how much that will be enforced. 

So, in practical terms, the new system looks like this: pay a shop ₹1,800, and there is no MDR. Pay ₹2,500, and the eligible merchant incurs 0.4%, or ₹10. Pay ₹10,000, and the MDR works out to ₹40. Pay ₹1 lakh, and the 0.4% calculation would be ₹400, but the cap brings the charge down to ₹300. For consumers, therefore, nothing changes immediately at the checkout.  

No MDR on person-to-person transfers 

The distinction becomes even clearer when you are paying another person. Send your friend ₹25,000 for your share of a holiday, transfer ₹50,000 to a family member, or send ₹2 lakh to someone else through UPI, and there is no MDR. Person-to-person transactions remain completely free, irrespective of the amount. P2P transactions account for around 70% of UPI’s total transaction value, according to government data. 

There is also protection for the smallest merchants. Merchants receiving up to ₹1 lakh a month through UPI QR codes under the specified small-merchant category remain under zero MDR. The government says roughly 96% of all P2M transactions will remain unaffected.

So why introduce MDR at all? 

The official argument is sustainability. UPI has grown into enormous infrastructure, with banks, payment service providers, apps, acquiring institutions, cybersecurity systems, and NPCI all involved in keeping billions of transactions moving. In August alone, UPI processed about 24 billion transactions worth roughly $311 billion. 

The new MDR creates a revenue pool for the ecosystem. At 0.4%, industry estimates suggest it could potentially generate up to ₹16,000 crore annually, depending on transaction volumes and the proportion of payments that fall within the chargeable categories. 

But this is where the more interesting argument begins. 

Ashneer Grover has questioned whether the system genuinely needs the additional revenue. His argument rests on the financial strength of the institutions sitting around UPI. The RBI transferred a record ₹2.87 lakh crore surplus to the Union government for FY26. Listed commercial banks, meanwhile, reported consolidated net profits of ₹4.11 lakh crore in FY26. 

Grover also points to NPCI’s pre-tax surplus of ₹1,888 crore, and his question is blunt: “Nuksaan kis ka ho raha hai UPI se aur kaunsi subsidy de rahi hai Govt UPI pe jo chubh rahi hai?” 

He has also highlighted the estimated ₹30,500 crore annual cost of running ATMs and cash logistics in India, arguing that if the objective is efficiency, encouraging UPI should reduce the country’s dependence on a much more expensive cash infrastructure. 

His larger criticism is even sharper: “Any levy on UPI is just tax collection.” 

Technically, that description needs a qualification. The government says MDR is not a tax, nor is it a charge collected by the government or NPCI. It is a fee distributed among participants in the payments ecosystem. But it is hard to ignore Grover’s interpretation and underlying question: if digital payments are a piece of national infrastructure that make commerce cheaper, faster, and more transparent, what happens when that infrastructure begins carrying a price? And this then becomes, at some level, an indirect tax of sorts. 

The immediate answer is reassuring. Customers remain protected. P2P remains free. Small payments remain free. Small merchants remain protected. The longer-term question is behavioural. 

What this means for merchant transactions 

A merchant technically cannot add the MDR as a UPI surcharge. But merchants still operate on margins. If payment costs rise, businesses have several choices: absorb the cost, reduce other expenses, adjust prices over time and pass it on to the consumer, or encourage customers towards cash or another payment method. 

That does not mean India will suddenly return to cash. Nor does it mean MDR will inevitably raise consumer prices. But it creates a new economic variable in a system whose extraordinary success was partly built on making digital payments feel free. 

And that is perhaps the real significance of the new MDR. UPI has been one of India’s rare pieces of infrastructure that made the digital economy feel almost invisible. You didn’t think about networks, banks, settlement systems, cybersecurity, or switching fees. You simply scanned and paid. 

Now the infrastructure has acquired a price, even if the consumer does not see it on the bill. 

The question India will have to answer over time is whether that price strengthens the system that made UPI possible, or whether it creates just enough friction to make cash look attractive again. 

As Grover puts it: “UPI is the one scientific achievement of India everyone acknowledges.” The experiment now is whether India can monetise that achievement without making people rethink why they embraced it in the first place, and if everyone veers away from it.
