A Deliberate Policy Choice
The simplest reason UPI remains free for individuals is that it was designed that way on purpose. The Government of India and the Reserve Bank of India (RBI) view UPI not just as a product, but as critical public infrastructure. Their primary goal is to
accelerate financial inclusion and steer the country towards a digital-first economy. By making bank-to-bank transfers seamless and free, they encourage widespread adoption, from bustling cities to remote villages. Keeping person-to-person (P2P) transactions free of charge lowers the barrier to entry, getting more people to participate in the formal financial system and reducing the economy's reliance on cash. This strategic decision ensures that the digital payments revolution remains accessible to everyone.
The P2P vs. P2M Distinction
It's crucial to understand the difference between P2P (Person-to-Person) and P2M (Person-to-Merchant) transactions. When you send money to a friend or family member, it's a P2P transfer. The National Payments Corporation of India (NPCI), the body that operates UPI, has consistently clarified that these transactions will remain completely free for both the sender and the receiver, regardless of the amount. The costs come into play on the merchant side. As of October 2026, a Merchant Discount Rate (MDR) of 0.4% applies to specific P2M transactions over ₹2,000. However, this charge is levied on the merchant, not the customer. All UPI transactions remain free for users.
Who Actually Bears the Cost?
If you and your friend aren't paying, who is? Running the massive UPI infrastructure—with its servers, security protocols, and customer support—isn't free. The costs are shared among different stakeholders. For a long time, banks and payment apps absorbed these costs. The government also steps in by providing financial incentives from the public budget to support the ecosystem, essentially using taxpayer money to keep the service free for the public good. The recently introduced MDR on larger merchant transactions is also designed to help the ecosystem become more financially sustainable in the long run, ensuring that banks and payment providers can continue to invest in and innovate the platform without passing costs to individual users for their daily P2P transfers.
How Do Payment Apps Make Money?
This brings us to the business model of apps like PhonePe, Google Pay, and Paytm. If they don't charge for P2P transfers, how are they valued at billions of dollars? Their strategy is to use free UPI transfers as a customer acquisition tool. Once you're on their app, they offer a suite of other revenue-generating services. These include collecting commissions on mobile recharges and bill payments, selling financial products like insurance and loans, facilitating investments in mutual funds, and charging fees to businesses for using their payment gateway services. They also earn money through brand partnerships and by offering value-added services to merchants. In essence, your free P2P transfer is the entry point into a larger digital marketplace.
