Free at the Counter, Costly Behind It: Who Should Pay for UPI's ₹20,000-Crore Machinery?

A Payment System Is Free Only Until Someone Asks Who Built It

UPI processed 24.07 billion transactions worth ₹29.37 trillion in September 2026. To the person paying at a shop, every one of those transactions was free. To the banks and apps running them, none were. The industry estimates the system's annual cost at about ₹20,000 crore. The deferred fee is the first serious attempt to decide who should carry that bill.

Who the fee actually reaches The design is narrow on purpose:

• payments between individuals stay free; - merchant payments below ₹2,000 stay free; - merchants receiving less than ₹1 lakh a month through UPI are fully exempt; - fuel, rail tickets, farm inputs, utility bills, insurance and taxes pay a flat ₹5 above ₹2,000. What remains is a 0.4 percent fee on payments above ₹2,000 at medium and large merchants, capped at ₹300. According to the industry figures reported, such payments are about 4 percent of person-to-merchant transactions by number but around two-thirds by value. The government says about 96 percent of merchant transactions remain untouched. So the fee does not land on the vegetable seller or the student splitting a bill. It lands on an electronics shop selling a ₹40,000 phone, which pays ₹160 on that sale. That is still less than the 1-3 percent the same shop pays when the customer uses a card.

How the

cost travels The mechanism matters more than the rate. A merchant does not experience 0.4 percent as a percentage of revenue. It experiences it as a share of margin. For a shop with a healthy margin, ₹160 on a ₹40,000 sale is minor.

For a business that earns a fixed commission it cannot raise, the same fee eats directly into earnings. LPG distributors made exactly this case to the Petroleum Ministry, as reported by The Hindu: they cannot set cylinder prices, so the fee comes out of a fixed commission.

That gives a business three options: absorb the fee, pass it on to customers or nudge them back to cash or to payments split below ₹2,000. The government says consumers will not bear the fee. Retailers say margins will push them to recover it somewhere. Where the fee finally rests depends on each merchant's margin, not on the rule.

The bill zero MDR postponed Since 2019, Section 10A of the Payment and Settlement Systems Act barred charges on prescribed electronic payments.

It was amended in August 2026 to let the Centre decide which transactions stay free. In the zero-fee years, the gap was met partly by budget support - ₹2,196 crore for the UPI incentive scheme in 2025-26 - against an industry cost estimated at about ₹20,000 crore.

NPCI argues, as reported, that fee revenue will fund innovation and let smaller fintechs compete with well-capitalised tech conglomerates. Traders, led by CAIT, called the deferral timely for the festive and wedding season.

The examiner's point Digital public infrastructure can be free to its users, but it is never free to run.

The design choice is only about which group pays - taxpayers through subsidy, large merchants through a fee or smaller players squeezed out by firms that can absorb losses. The deferral did not answer that question. It postponed it until after Diwali.
