UPI Payments Explained: Unified Payments Interface (UPI) transactions come at zero cost for users and merchants, yet leading digital payment apps like PhonePe, Google Pay, and Paytm are generating thousands of crores in revenue each year. The secret lies not in basic UPI transfers, but in a diversified revenue model built around merchant services, credit products, bill payments, and hardware subscriptions.

UPI dominates India’s payment landscape

According to a recent update from the Finance Ministry, UPI has emerged as India’s most preferred payment method. Nearly 57 percent of all digital transactions in the country are now processed through UPI. Independent research further indicates that UPI accounts for almost 90 percent of cashless transaction volume and over 70 percent of total transaction value.

Despite this dominance, UPI payments remain free. Since 2020, the Merchant Discount Rate (MDR) on UPI transactions has been set at zero, raising an obvious question: where does the money come from?

Why free UPI transactions still generate income

While person-to-person (P2P) payments form a large chunk of UPI volume, they contribute very little to overall earnings. These transactions bring in a tiny fixed fee, which is shared between banks and app providers. In value terms, this amounts to just 0.3–0.4 basis points, contributing less than 10 percent to the net revenue pool.

The real earnings begin when payments move from consumers to businesses.

Merchant payments drive the bulk of profits

Industry reports reveal that nearly 75 percent of net revenue for UPI platforms comes from the merchant side. Consumer-to-merchant (P2M) transactions are far more profitable because platforms earn fees through merchant acquisition, payment processing, and value-added services.

As India’s cashless economy expands, nearly half of private final consumption spending is now digital. This shift has significantly strengthened the merchant revenue stream for payment apps.

Credit cards and bill payments boost margins

One of the fastest-growing income sources is credit card processing. Credit card spending in India has been rising at an annual rate of over 20 percent, and these transactions carry higher processing fees than standard UPI transfers.

Bill payments are another key contributor. Transactions routed through the Bharat Bill Payment System (BBPS)—managed by Bharat Bill Payment System—crossed ₹10 lakh crore in FY25, with volumes growing close to 80 percent year-on-year. Platforms earn 8–10 basis points on bill payments, far higher than basic UPI transfers.

Device rentals add stable recurring income

Payment hardware such as POS machines and soundboxes has become a steady revenue source. Merchants pay monthly rental fees, similar to a subscription model. In FY25 alone, device rentals contributed around ₹2,000 crore to the industry’s revenue, offering predictable and recurring cash flow.

How big is the payment revenue pool?

Estimates suggest that the gross revenue pool from digital payments stands at nearly ₹2.5 lakh crore. After accounting for banking fees, technology costs, and processing expenses, the net revenue pool is around ₹15,000 crore.

This means payment platforms have achieved significant scale even without aggressively selling loans or other financial products.

Future growth: credit is the key

Looking ahead, analysts project the net revenue pool to grow at 20 percent annually, potentially reaching ₹38,500 crore by FY30. A major growth driver will be the rising share of credit-based payments.

Currently, credit accounts for about 20 percent of total cashless transaction value. By FY30, this could rise to 25 percent, pushing industry margins higher. The growing adoption of RuPay credit cards on UPI is a clear indicator of this trend.

Payments are just the beginning

Despite impressive topline numbers, earnings per user remain modest. On average, payment platforms earn less than ₹300 per customer annually, with profits below ₹150 per user. In comparison, SBI Cards earns nearly ₹2,000 per active card before tax.

This gap highlights where the future lies: credit, lending, and financial products, not just payments.
