India’s Unified Payments Interface (UPI) has become one of the world’s largest digital payment systems, but its rapidly expanding scale is creating a significant financial sustainability challenge. A parliamentary standing committee has highlighted a wide gap between the estimated annual operational cost of the UPI ecosystem and the government’s budgetary support, with the system costing about ₹20,700 crore while the government has allocated only ₹2,000 crore to support UPI and RuPay transactions.
The committee has recommended a calibrated and self-sustaining revenue model for digital payments, including the introduction of a tiered Merchant Discount Rate (MDR) on high-value UPI transactions. The recommendation comes as the government considers how to fund cybersecurity, fraud prevention and network infrastructure without placing the entire financial burden on the public exchequer.
UPI Faces a Major Funding Gap
According to the parliamentary panel, the estimated operational cost of the UPI ecosystem is around ₹20,700 crore, compared with a government allocation of just ₹2,000 crore for incentives related to UPI and RuPay transactions.
The ₹2,000 crore allocation therefore covers only a small portion of the industry’s estimated costs.
| Metric | Amount |
|---|---|
| Estimated UPI operational cost | ₹20,700 crore |
| Government allocation | ₹2,000 crore |
| Funding gap | ₹18,700 crore |
| Government support as share of estimated cost | About 10% |
| Proposed solution | Calibrated, tiered MDR |
| Main concern | Long-term financial sustainability |
The committee has warned that continued dependence on limited government incentives could constrain the ability of payment service providers to invest adequately in the infrastructure required to support India’s rapidly growing digital payments network.
Why UPI Costs Are Rising
UPI transactions may appear almost costless to consumers, but the underlying payment infrastructure requires substantial spending.
Banks, payment service providers and technology companies must maintain servers, cybersecurity systems, fraud-monitoring infrastructure and payment-processing networks.
The system also needs to handle enormous transaction volumes continuously, including during periods of peak demand.
UPI Infrastructure Costs

As UPI usage expands, these costs are expected to increase further.
Zero-MDR Model Created the Current Challenge
India introduced zero Merchant Discount Rate on UPI transactions in January 2020 to accelerate digital-payment adoption.
MDR is the fee paid by a merchant for accepting a digital payment. It is generally shared among the participants involved in processing a transaction.
By keeping MDR at zero for UPI transactions, India effectively removed a direct revenue source from the payment ecosystem.

Government incentive and ecosystem funding
The zero-MDR approach helped make UPI extremely attractive for consumers and merchants, but it also created a long-term question over who should pay for the infrastructure.
Government Support Has Not Kept Pace With Costs
The government introduced incentives to compensate banks and payment companies for processing certain low-value transactions without charging MDR.
However, the parliamentary panel says the current allocation is substantially below the industry’s estimated operating costs.
The committee has therefore called for a more sustainable revenue structure.

Large funding gap
The committee believes this gap cannot continue indefinitely without affecting the ecosystem’s ability to invest in infrastructure.
Panel Recommends Tiered MDR
The parliamentary committee has recommended introducing a calibrated MDR structure, particularly for high-value merchant transactions.
The idea is not to impose a blanket charge on every UPI payment.
Instead, transactions could be categorized according to their value and type, with higher-value commercial payments potentially attracting a small fee.
Proposed Tiered Model
Low-value UPI payments
↓
Continue with minimal or zero charges
High-value merchant payments
↓
Small calibrated MDR
Large commercial transactions
↓
Higher applicable MDR
↓
Revenue for payment ecosystem
The exact rates and thresholds would need to be determined by the government and relevant regulators.
Small Merchants Could Be Protected
One of the central concerns surrounding MDR is its potential impact on small merchants.
Small retailers, street vendors and micro-businesses have benefited significantly from free digital payments.
If charges are imposed broadly, some merchants could potentially return to cash transactions.
The parliamentary panel has therefore emphasized the need for safeguards.
Potential Structure
Small merchants
↓
Low-value transactions
↓
Minimal or zero MDR
Larger merchants
↓
Higher-value transactions
↓
Calibrated MDR
↓
Greater contribution to ecosystem costs
Such a structure could preserve the benefits of free or inexpensive digital payments for small businesses while generating revenue from larger transactions.
Person-to-Person Payments Could Remain Free
Another important distinction is between merchant payments and person-to-person transfers.
A tiered MDR system could focus primarily on commercial transactions rather than everyday transfers between individuals.
This would help preserve UPI’s role as a convenient system for sending money to friends, family members and other individuals.
Potential Payment Categories
Person-to-person
↓
Remain free
Small merchant payments
↓
Low or zero MDR
High-value merchant payments
↓
Calibrated MDR
Large commercial payments
↓
Higher MDR
This approach could reduce the impact on ordinary consumers.
Why High-Value Transactions Are Being Targeted
High-value merchant transactions are considered more suitable for MDR because businesses conducting larger transactions may be better positioned to absorb a small payment-processing fee.
For example, a large commercial purchase generates greater transaction value than a small neighborhood purchase.
A small percentage charge on high-value transactions could therefore generate meaningful revenue without significantly affecting everyday low-value payments.
UPI Has Become Critical Digital Infrastructure
UPI is no longer simply a payment application feature.
It has become a major component of India’s digital public infrastructure.
Millions of businesses use UPI to accept payments, while consumers use it for everything from grocery purchases and restaurant bills to utility payments and online shopping.
The system’s scale makes financial sustainability increasingly important.

A disruption to the payment infrastructure could therefore have consequences across the wider economy.
Cybersecurity Costs Are Increasing
As transaction volumes grow, so does the potential attack surface for fraudsters and cybercriminals.
Payment companies must continually invest in fraud detection, authentication, monitoring and security infrastructure.
The parliamentary panel has specifically warned that inadequate funding could threaten investment in cybersecurity and fraud prevention.
Growing Security Requirements
More transactions
↓
More payment data
↓
More potential fraud attempts
↓
Advanced fraud detection
+
AI-based monitoring
+

↓
Higher operating costs
Ensuring that the UPI ecosystem remains secure will require continuous investment.
Fraud Prevention Is Becoming More Important
Digital-payment fraud can take many forms, including phishing, social engineering, fake payment requests and account compromises.
As UPI becomes more deeply integrated into everyday commerce, maintaining consumer confidence will depend on keeping fraud levels under control.
Payment providers therefore need resources to develop better detection systems and respond to emerging threats.
Network Infrastructure Must Keep Expanding
UPI has to handle massive transaction volumes while maintaining reliability.
This requires investment in servers, connectivity, software, payment gateways, bank systems and redundancy.
The system must also be capable of handling sudden increases in transaction activity.
Infrastructure Cycle
Higher UPI adoption
↓
More transactions
↓
Greater processing requirements
↓
More infrastructure
↓
Higher maintenance costs
↓
Need for sustainable revenue
Without adequate funding, the ecosystem could face pressure to reduce investment or seek alternative sources of revenue.
UPI Could Process Even More Transactions
The parliamentary panel has indicated that UPI has the potential to reach significantly higher transaction volumes.
The committee has cited a scenario in which UPI could process as many as 150 billion transactions a month and add around 600 million new users.
If that scale is achieved, infrastructure and cybersecurity costs would likely increase further.
Potential Growth
Current UPI ecosystem
↓
More users
↓
More merchants
↓
More transactions
↓
150 billion monthly transactions potential
↓
Higher infrastructure requirements
The funding model therefore needs to account for future growth rather than only today’s expenses.
Government Wants a Self-Reliant Payment Ecosystem
The committee’s recommendation reflects a broader concern that UPI should eventually become financially sustainable without requiring large government subsidies.
A self-sustaining model could allow payment companies and infrastructure providers to fund investments through transaction-related revenue.
The government could then reduce its role as the primary source of financial support.
New Law Opens Door to Digital Payment Charges
Parliament has recently amended the Payment and Settlement Systems Act to create a legal framework allowing charges on digital payments.
The amendment does not automatically impose an MDR on UPI transactions.
Instead, it provides the statutory basis for a calibrated charging mechanism if the government decides to operationalize one.
This distinction is important because consumers should not assume that UPI charges will immediately apply.
No Immediate UPI Fee for Consumers
The parliamentary recommendation does not mean that users will suddenly be charged for making UPI payments.
Any future MDR structure would require the government and relevant authorities to determine the applicable rates and transactions.
The committee has specifically supported a calibrated approach designed to protect smaller transactions.
What Could Change
Today
↓
Most UPI payments
↓
Zero MDR
Future possibility
↓
Small-value payments protected
+
High-value merchant payments
↓
Calibrated MDR
The exact structure remains subject to government decisions.
Payment Companies Need a Sustainable Revenue Model
Banks and payment service providers have invested heavily in building the infrastructure required to support UPI.
However, transaction growth without corresponding revenue growth can make it difficult to justify large future investments.
A sustainable revenue model could provide stronger incentives for companies to continue investing in technology and security.
Fintech Companies Could Be Affected
Fintech platforms such as payment applications depend on the broader UPI infrastructure.
Any changes to MDR could influence how costs and revenues are distributed among banks, payment service providers and merchants.
The impact would depend on the final rules.
Possible Industry Effect
MDR introduced
↓
Revenue generated
↓
Revenue shared across ecosystem
↓
Payment providers receive compensation
↓
Higher capacity for infrastructure investment
The distribution mechanism will be critical to the success of any new model.
Merchants May Face New Costs
For merchants, the introduction of MDR would represent a change from the current zero-cost model.
However, if the fee is limited to high-value transactions and kept at a low rate, the impact on small businesses could remain limited.
Large retailers and businesses processing substantial payment volumes would likely bear a greater share of the cost.
Could MDR Increase Consumer Prices?
One concern is whether merchants would pass any payment-processing fee on to customers.
A small MDR could become part of a merchant’s overall operating cost.
Whether that leads to higher consumer prices would depend on competition, margins and the size of the fee.
The government’s challenge will be to design a system that generates enough revenue without weakening UPI’s affordability advantage.
UPI’s Free Model Helped Drive Adoption
One of UPI’s biggest strengths has been its simplicity and low cost.
Consumers can make payments without worrying about transaction charges in most everyday situations.
This helped UPI become deeply embedded in India’s payment habits.
Digital Adoption Cycle
Free transactions
↓
More consumer adoption
↓
More merchants accept UPI
↓
More transactions
↓

↓
Network effect
Any future charging mechanism will need to preserve this network effect.
India Must Balance Growth and Sustainability
The policy challenge is therefore not simply whether UPI should remain free.
It is about determining who should finance the infrastructure supporting the system.
Possible funding sources include government subsidies, merchant fees, private investment or a combination of these approaches.
Funding Options
Government subsidies
+
Merchant MDR
+
Private investment
+
Other ecosystem revenue
↓
Sustainable UPI infrastructure
A blended model could potentially reduce the burden on any single participant.
What It Means for Consumers
For consumers, the most important point is that the parliamentary recommendation does not immediately introduce a UPI fee.
The panel is proposing a future framework focused mainly on high-value merchant transactions.
Everyday person-to-person payments and low-value transactions could remain protected under a calibrated structure.
What It Means for Small Businesses
Small merchants could benefit if the government implements strong safeguards.
Keeping low-value transactions free or inexpensive would allow small businesses to continue using UPI without significantly increasing operating costs.
However, larger merchants could face new payment-processing expenses if MDR is introduced.
What It Means for Banks and Fintechs
Banks and payment service providers could benefit from a more predictable source of revenue.
Additional revenue could help finance cybersecurity, fraud prevention, infrastructure upgrades and system reliability.
However, the final MDR structure will determine how much of the new revenue reaches each participant.
What It Means for the Government
The government could potentially reduce the fiscal burden associated with subsidizing UPI transactions.
At the same time, it would need to ensure that the system remains affordable and accessible.
The challenge is to move toward financial sustainability without undermining the policy goals that made UPI successful.
What Investors Should Watch
Investors should monitor:
- Government decisions on MDR
- UPI transaction growth
- Merchant adoption
- Payment-processing costs
- Cybersecurity spending
- Fraud levels
- Government subsidy allocations
- Revenue models of payment companies
- Regulatory changes
- High-value transaction volumes
The most important development will be the government’s response to the parliamentary panel’s recommendations.

MORE SUSTAINABLE UPI
The Bigger Picture
UPI has transformed India’s payments landscape by making instant digital transactions widely accessible to consumers and businesses at little or no direct cost. But its success has created a new policy challenge: maintaining a massive payment infrastructure requires substantial and growing investment. The parliamentary panel’s estimate of ₹20,700 crore in annual operational costs compared with only ₹2,000 crore in government support highlights the scale of the funding gap. The committee believes that relying primarily on government incentives is unlikely to be sustainable as transaction volumes continue to rise.
The proposed solution is a calibrated revenue model, with the possibility of tiered MDR on high-value merchant transactions while protecting small merchants and everyday person-to-person transfers. Such a system could give banks, payment providers and technology companies a more reliable source of funding for cybersecurity, fraud prevention and infrastructure. At the same time, the government will need to ensure that introducing charges does not weaken UPI’s biggest advantage: its affordability and simplicity.
Looking Ahead
The next important step will be the government’s decision on whether and how to operationalise a tiered MDR framework. The recently created statutory ability to permit charges on digital payments provides a legal pathway, but the government will still need to determine transaction thresholds, rates, exemptions and how revenue will be distributed across the payment ecosystem. Protecting small merchants and low-value transactions will likely remain a central consideration.
Over the longer term, UPI’s financial model will need to evolve alongside its scale. If transaction volumes reach the levels anticipated by the parliamentary panel, the cost of maintaining reliable and secure infrastructure could rise substantially. A carefully designed MDR system could reduce dependence on government subsidies while preserving free or low-cost access for ordinary users. The success of the policy will ultimately depend on whether India can make UPI financially sustainable without undermining the digital-payment adoption that made the platform a global model.
