MUMBAI, India | September 22, 2026 —
India’s new UPI fee shift could dramatically change the economics of digital payments, opening a fresh revenue stream for major apps such as PhonePe and Google Pay after years of operating in a largely zero-fee ecosystem.
From October 15, 2026, a 0.4% merchant discount rate, or MDR, will apply to select UPI merchant transactions above ₹2,000. Person-to-person transfers and payments to small merchants will remain outside the standard charge framework.
The new structure could prove especially lucrative for PhonePe and Google Pay.
Together, the two apps accounted for around 80% of UPI payment value in August, according to Reuters. Bernstein estimates that the new fee structure could create up to $1.1 billion in annual revenue for payment apps by March 2028. Based on current market share, PhonePe and Google Pay could together capture around $900 million of that pool.
That does not mean the companies are guaranteed to earn that amount. Actual revenue will depend on transaction mix, exemptions, fee sharing and future market-share changes.
Why the UPI Fee Rule Is Such a Big Change
For more than six years, UPI grew rapidly under a largely zero-MDR model.
Consumers became accustomed to scanning QR codes and paying merchants without seeing an additional transaction charge. Banks, payment apps and payment infrastructure companies, however, still had to bear technology, fraud-management, customer-support and operational costs.
The new MDR framework introduces a transaction-linked revenue model for certain higher-value merchant payments.
Industry analysts view that shift as an attempt to make the UPI ecosystem financially sustainable while still keeping smaller-value transactions and person-to-person transfers largely protected.
PhonePe and Google Pay Could Be the Biggest Winners
Scale matters enormously under the new structure.
PhonePe and Google Pay already dominate UPI by payment value. Therefore, even a relatively small fee applied across millions of qualifying merchant transactions could translate into substantial revenue.
Reuters reported that Bernstein expects payment apps to generate as much as $1.1 billion annually from the fee pool by March 2028.
If PhonePe and Google Pay maintain their combined market share, their share could approach $900 million annually.
That could give the two platforms additional money to invest in technology, customer acquisition and geographic expansion.
Rural India Could Become the Next Battleground
The new economics could make expansion beyond major cities more attractive.
Industry sources told Reuters that fresh fee income may encourage leading apps to invest more heavily in rural markets, where transaction values can be lower and monetisation has historically been more difficult.
Payment data can also support other financial services.
Platforms can potentially use transaction behaviour, subject to applicable regulation and consent requirements, to design loans, merchant services and other financial products.
Therefore, the bigger commercial opportunity may eventually extend well beyond the UPI fee itself.
Smaller UPI Apps Face a Tougher Contest
The same reform that creates a revenue opportunity could also strengthen existing market leaders.
PhonePe and Google Pay already process most UPI payment value. More revenue could allow them to invest even more aggressively in expansion and new products.
That has revived discussion about market concentration.
The National Payments Corporation of India has previously considered a 30% market-share cap for individual UPI apps, but implementation has been deferred more than once.
Smaller payment companies may therefore focus more heavily on high-value categories such as utility bills, ticket bookings, business payments and online commerce.
Banks Will Also Receive a Large Share
Payment apps will not keep the entire MDR.
Citi estimates that the broader annual UPI fee pool could reach around ₹160 billion to ₹170 billion, with approximately 60% flowing to banks, 25% to app providers and 15% to payment aggregators.
That means banks with significant UPI exposure could also benefit from the transition.
Analysts have highlighted banks including Yes Bank, Bank of Baroda, Punjab National Bank and IndusInd Bank as potential beneficiaries.
Payment companies such as Paytm and MobiKwik have also drawn investor attention since the fee framework was announced.
Will Customers Have to Pay More?
This is the biggest question for ordinary users.
The MDR is formally a merchant-side charge rather than a direct fee imposed on consumers.
Current rules also preserve zero MDR for small merchants and person-to-person transfers, while some essential-service and capital-market transactions receive lower or capped charges.
However, businesses still have to absorb the cost of qualifying transactions.
Reuters reported that regulations prohibit merchants from explicitly passing the MDR directly to customers, although some industry participants believe businesses could indirectly adjust prices over time.
For a ₹5,000 qualifying transaction, a 0.4% MDR would equal ₹20 before considering any applicable exemptions or caps.
Therefore, consumers may not see a separate “UPI fee” on their screens, but merchants will closely watch how the additional cost affects margins.
Small Merchants Remain Protected
The government and payment authorities have not imposed the standard MDR across every UPI transaction.
Small merchants remain exempt, while person-to-person payments continue without MDR.
This distinction is important because a large portion of India’s UPI ecosystem consists of small shops, roadside vendors and individuals transferring money to one another.
The new framework therefore targets monetisation primarily around higher-value commercial transactions rather than every QR-code payment.
UPI Is Already Operating at Enormous Scale
The potential revenue numbers become easier to understand when viewed against UPI’s scale.
NPCI data shows that UPI processed 24.51 billion transactions worth around ₹29.82 trillion in August 2026.
That enormous transaction base means even a small fee applied to only a portion of merchant payments can create a multibillion-rupee revenue pool.
UPI has become deeply embedded in daily Indian commerce, from grocery stores and restaurants to travel bookings, online shopping and business payments.
The Bigger UPI Story Has Now Changed
For years, the biggest UPI story was growth.
Now, the next phase could increasingly revolve around monetisation.
The October 15 fee change gives banks, fintech companies and payment apps a clearer way to earn money from qualifying transactions.
For PhonePe and Google Pay, that opportunity could be particularly significant because they already control such a large share of UPI payment value.
The bigger question is what happens next.
If fee revenue finances better infrastructure, deeper rural expansion and stronger fraud protection, the change could strengthen the ecosystem.
At the same time, regulators will need to keep watching competition, merchant costs and whether market dominance becomes more concentrated.
India’s UPI revolution is therefore entering a new chapter.
The network that changed how India pays is now beginning to change how its biggest payment apps make money.
