UPI has become one of the most common ways to pay in India, covering everything from a small tea purchase to smartphones, appliances and other high-value products. However, reported changes to the Merchant Discount Rate (MDR) framework for certain UPI merchant payments have created questions among shopkeepers about how much they could actually pay when accepting larger transactions.
The reported framework is expected to apply from October 15, 2026, with a 0.4% MDR on specified person-to-merchant (P2M) UPI transactions above ₹2,000.
This does not mean every UPI payment will automatically attract the same fee. The applicable charge can depend on the merchant category, transaction type, exemptions and other conditions.
So, what would happen if a customer buys goods worth ₹10,000 and pays through UPI? Here is the calculation.
How Much Is 0.4% MDR on a ₹10,000 UPI Payment?
Suppose a merchant accepts a UPI payment of ₹10,000 and that particular transaction is covered by a 0.4% MDR.
The calculation would be:
₹10,000 × 0.4% = ₹40
Therefore, the MDR on the transaction would be ₹40.
This fee is associated with the merchant payment-acceptance system. It should not be confused with an additional government tax on the customer's ₹10,000 purchase.
Under the example described in the source, if the goods cost ₹10,000, the customer still initiates a payment of ₹10,000. The MDR is a merchant-side cost subject to the applicable payment arrangement.
What Happens When GST Is Added to the MDR?
Another point that can create confusion is GST.
In this example, GST is not calculated on the entire ₹10,000 transaction merely because the payment was made through UPI. Instead, where applicable, GST would be calculated on the MDR or service fee.
If the MDR is ₹40 and GST is charged at 18%, the calculation would be:
₹40 × 18% = ₹7.20
That would make the total MDR-related cost:
₹40 + ₹7.20 = ₹47.20
So, under this illustrative calculation, a ₹10,000 UPI merchant transaction subject to the 0.4% MDR could involve a total merchant-side cost of ₹47.20 including 18% GST on the MDR.
The effective settlement impact could therefore be approximately:
₹10,000 - ₹47.20 = ₹9,952.80
However, this should be treated as an illustration. The actual settlement amount can depend on the merchant's agreement with its bank, payment service provider or acquiring entity.
Will Customers Have to Pay ₹10,047.20?
Not under the example described above.
The MDR is presented as a cost associated with merchant payment acceptance rather than an automatic surcharge to be added to the customer's bill.
If a product costs ₹10,000, the customer would normally make a UPI payment of ₹10,000. The merchant's MDR and applicable taxes would be accounted for separately according to the merchant's payment arrangement.
Consumers should therefore not assume that a 0.4% MDR automatically makes a ₹10,000 purchase cost ₹10,047.20.
Does Every UPI Transaction Above ₹2,000 Attract 0.4% MDR?
No. The information provided indicates that the 0.4% rate is not a universal charge on every UPI transaction above ₹2,000.
The applicable structure can vary depending on the type of payment and merchant category.
The source also states that small merchants may receive relief for UPI QR transactions up to a specified monthly threshold. Therefore, shopkeepers should first establish which category they fall under instead of assuming that every payment above ₹2,000 will result in an MDR deduction.
Different MDR Rules for Some Merchant Categories
The supplied information also describes separate rates for certain sectors.
For UPI transactions above ₹2,000 in specified essential categories such as railways, telecom, insurance, fuel and agricultural inputs, the source states that the applicable MDR would be a fixed ₹5 per transaction.
Meanwhile, transactions involving categories such as mutual funds, securities, stockbrokers and dealers are described as attracting an MDR of 0.02%, subject to a maximum of ₹300 per transaction.
These category-specific provisions are important because applying the standard 0.4% calculation to every merchant could produce an incorrect result.
₹10,000 UPI Transaction: Calculation at a Glance
For an eligible merchant transaction subject to the 0.4% MDR:
Transaction value: ₹10,000
MDR at 0.4%: ₹40
GST at 18% on ₹40: ₹7.20
Total illustrative merchant cost: ₹47.20
Illustrative net amount after these charges: ₹9,952.80
Amount paid by customer: ₹10,000
The calculation applies only where the transaction is actually covered by the stated 0.4% MDR structure.
What Shopkeepers Should Check
Merchants should avoid assuming that every UPI payment above ₹2,000 will be treated identically. The applicable charge can depend on merchant classification, transaction category, monthly payment volume and the commercial arrangement with the payment provider.
Shopkeepers should check their merchant agreement and the applicable payment-provider or regulatory notification to understand whether a particular transaction attracts MDR and how it will appear in settlement.
The key takeaway is simple: if a ₹10,000 UPI merchant payment is subject to a 0.4% MDR, the basic MDR works out to ₹40. If 18% GST is additionally applicable to that ₹40 fee, the illustrative total becomes ₹47.20. The customer, however, would still pay the purchase amount of ₹10,000 rather than automatically bearing this merchant-side fee.
