A Revolution in Digital Payments
Launched in 2016, UPI’s growth has been nothing short of explosive. By processing billions of transactions monthly, it has become the backbone of India's digital economy. With over 550 million users as of mid-2026, the platform has been a key driver of financial
inclusion, bringing millions of small merchants and rural users into the formal economy. The simple scan-and-pay mechanism has made digital payments accessible to everyone, from street vendors to large retailers. This mass adoption was fuelled by a critical policy decision: making transactions free for both users and merchants.
The Zero-Fee Dilemma
The success of UPI is directly tied to its zero Merchant Discount Rate (MDR) policy, which was implemented in 2020 to boost adoption. MDR is a fee that merchants pay to banks and payment service providers (PSPs) for processing digital transactions. While making UPI free was a masterstroke for user growth, it removed the primary revenue source for the ecosystem's players. Banks, fintech companies like PhonePe and Google Pay, and the National Payments Corporation of India (NPCI) itself incur significant costs to keep the UPI rails running smoothly. These costs include massive investments in server infrastructure, cybersecurity, fraud detection, and round-the-clock technical support.
Who Actually Pays for 'Free' UPI?
Currently, the costs are being borne by the banks and PSPs, with some support from government subsidies. However, these incentives have been inconsistent and cover only a fraction of the industry's expenses. Banks have voiced concerns about the mounting financial burden of maintaining the infrastructure without any transaction-based revenue to offset it. Similarly, fintech payment apps, which have spent heavily on customer acquisition, find themselves in a position where their core service generates massive volumes but no direct income. This has forced them to pivot towards cross-selling other financial products like loans, insurance, and wealth management services to achieve profitability.
The Search for a Sustainable Path
Recognising the unsustainability of a purely subsidy-reliant model, the government has begun exploring a middle path. In August 2026, an amendment to the Payment and Settlement Systems Act created a legal framework that could allow for charges on certain UPI transactions. However, the government has been quick to clarify that UPI will remain free for consumers for all person-to-person (P2P) transfers and the vast majority of merchant payments. The current thinking revolves around introducing a nominal MDR, potentially around 0.3%, only for high-value transactions (e.g., above ₹2,000) at larger merchants. This targeted approach aims to provide some revenue relief to the ecosystem without discouraging small merchants or impacting everyday users making small-value purchases.
Balancing Growth and Viability
The road ahead requires a delicate balancing act. Introducing fees, even for a small segment, risks alienating merchants and could slow down the very adoption that made UPI a global success story. A survey found that a majority of users might stop using the service if charges were passed on to them, highlighting the sensitivity around the 'free' tag. The goal is to create a model that ensures banks and fintechs are compensated for their investment, encouraging them to continue innovating and strengthening the system's security and resilience. The final decision on the structure of any potential MDR will rest with an NPCI-led committee, which will have to weigh the need for commercial viability against the platform's public utility role.
