Most people use UPI to transfer money directly from their bank account to a merchant. MDR on these standard, bank-account-funded UPI P2M transactions has been zero since January 2020.
UPI Credit Line works differently because the payment is funded through a pre-sanctioned credit facility rather than a savings or current account.
A bank pre-approves a credit limit for a customer and ties it directly to their UPI ID. When they pay, the money doesn’t come from their savings balance. It comes from borrowed funds, and repayment happens later, on the lender’s terms, much like a credit card.
The regulatory framework for this instrument was established by the Reserve Bank of India (RBI) in 2023, permitting commercial banks to integrate pre-sanctioned credit lines with users’ UPI accounts. Major banking institutions, including HDFC, ICICI, SBI, Axis, and Yes Bank, have since operationalized this capability. As adoption scales, it introduces a distinct cost structure that many merchants only identify during post-transaction settlement reconciliation.
The reason is simple: as soon as credit is involved, someone has to take on the financial risk. That risk has a price. MDR is how that price gets shared.
How UPI Credit Line Fees Are Structured
One fee drives almost everything a merchant pays on UPI Credit Line: interchange. The rest are smaller add-ons layered on top.
NPCI’s operating circular on Credit Line MDR (OC No. 202/2024-25, effective 16 October 2024) sets the baseline at 1.3% for merchants outside specific industry categories.
Rates for other segments are assigned by Merchant Category Code, so two merchants accepting the same product can see different numbers depending on how their business is classified.
Fee component | What it covers | Who sets it |
Interchange | Compensates the issuing bank for extending credit and carrying default risk | NPCI sets the rate; the issuing bank collects it |
PSP/app commission | Small cut for the app used to initiate payment | Defined within NPCI’s interchange framework |
Acquirer fee | Routing, authorisation, and settlement on the merchant’s side | Acquiring bank |
Platform fee | Gateway infrastructure: routing, fraud checks, dashboards, API access | Set independently by the payment gateway, on top of MDR |
RBI sits above all of this. It decides what counts as a valid credit product and what disclosures banks owe customers before a credit line can be linked to UPI. Issuing banks then set their own terms within that framework: interest-free periods, interest-bearing structures, credit limits. NPCI’s circular is what fixes the fee itself.
The transaction mechanics, stripped of the fee percentages already covered above:
- Customer selects Credit Line at checkout, alongside their linked bank accounts.
- The credit line is triggered. Funds come from the pre-sanctioned limit, not the savings balance.
- The issuing bank authorises the transaction and takes on the credit risk from that point.
- NPCI routes the payment across UPI rails.
- The acquirer settles the merchant side, deducting MDR before crediting the account.
- The merchant receives the net amount.
UPI Credit Line vs Other Payment Methods: A Cost Comparison
UPI Credit Line vs Standard UPI
Parameter | Standard UPI | UPI Credit Line |
MDR | Zero | ~1.3% to 2% |
Platform fee | Applicable (gateway charge) | Applicable |
Government mandate | Zero MDR confirmed | Operates under a market-driven framework without explicit statutory mandates. |
Risk to merchant | None | None (credit risk stays with bank) |
Customer benefit | Instant transfer | Pay later flexibility |
UPI Credit Line vs Credit Cards
Parameter | UPI Credit Line | Credit Card |
Typical MDR range | 1.3% to 2% | 1.5% to 3% |
Infrastructure | UPI rails (NPCI) | Visa/Mastercard/RuPay networks |
Settlement speed | As per UPI settlement cycles | 1 to 3 business days |
Customer adoption | Rapidly growing | Mature, but plateauing |
POS hardware required | No | For offline merchants |
Chargeback risk | Lower | Higher |
UPI Credit Line vs BNPL
Parameter | UPI Credit Line | BNPL |
Provider | Regulated banks | Mostly fintechs |
Regulatory oversight | Strong (RBI) | Still evolving |
Merchant fee model | Structured MDR | Often higher; varies by platform |
Consumer trust | High | Moderate |
Credit risk model | Bank-led | Platform-led |
For most merchants, UPI Credit Line sits in a genuinely useful middle ground. Cheaper than credit cards, better governed than BNPL, and operationally far simpler than managing credit in-house.
A Real-World Example
A customer buys ₹5,000 worth of products using UPI Credit Line. At the confirmed 1.3% MDR rate, here’s roughly how the fee splits across participants, based on the interchange-sharing pattern reported when NPCI set the framework:
Item | Amount |
Transaction value | ₹5,000 |
Total MDR (1.3%) | ₹65 |
Issuing bank (interchange) | ~₹59 |
UPI app commission (~0.08%) | ₹4 |
PSP/gateway | ~₹2 |
Merchant receives | ~₹4,935 |
Scale that to ₹10 lakh per month through UPI Credit Line at 1.3% MDR, and the monthly cost is ₹13,000. Whether that’s worth paying comes down to what credit-enabled customers are actually spending, and for most merchant categories, the answer tilts toward yes.
Factors That Affect How Much You Pay
Not all merchants pay the same rate, and the gap can be meaningful. The main variables:
- Merchant Category Code (MCC): Risk classification of your business type.
- Transaction value: Larger transactions may attract different rate tiers.
- Monthly transaction volume: Higher volumes create negotiation leverage.
- PSP or gateway relationship: Rate agreements vary significantly by provider.
- Risk profile: High chargeback histories push fees up.
- Bank partnerships: Some banks offer better rates to their own business customers.
Challenges and Hidden Costs to Watch
Fee transparency in the UPI Credit Line ecosystem is still catching up to where it needs to be. A few things that catch merchants off guard:
- Stacked fees: Gateway platform fees sit on top of MDR. Always ask for the full fee breakdown, not just the MDR headline number.
- GST on fees: Payment gateway charges attract 18% GST, which doesn’t always get foregrounded in pricing conversations.
- Variable bundling by provider: One PSP might quote 1.3% MDR + 0.3% platform fee as separate lines; another bundles it. Compare the total cost of the transaction, not individual components.
- Merchant opt-outs: Some small merchants have quietly stopped accepting credit-linked UPI payments to avoid MDR. That’s a valid call, but it carries the risk of pushing credit-ready customers toward competitors who do accept it.
The Regulatory Landscape Shaping UPI Credit Line Fees
The fee structure here sits inside a regulatory context that is genuinely still developing.
- RBI’s 2023 directive gave banks formal permission to link pre-approved credit lines to UPI accounts.
- For small merchants, UPI payments up to ₹2,000 incur no MDR and earn a 0.15% incentive on the transaction amount. If the transaction exceeds ₹2,000, MDR remains zero, but no incentive is provided.
- While UPI transactions for large merchants remain subject to zero MDR, government incentives are available only for eligible small merchants. Large merchants do not receive incentive payouts, regardless of the transaction value.
- Reuters reported in early 2025 that officials from the NPCI, RBI, and the Finance Ministry were discussing a potential 0.2% to 0.3% MDR for large merchants on standard UPI. As of mid-2025, this hasn’t been implemented; the Finance Ministry has confirmed that zero MDR remains in force for standard UPI.
The standardisation of UPI Credit Line fee ranges is expected as the product scales and NPCI issues clearer guidelines for participants. Keeping up with NPCI circulars isn’t just good practice for merchants in this space. It’s operationally necessary.
Best Practices for Merchants to Manage UPI Credit Line Fees
- Negotiate before you sign. MDR isn’t fixed, particularly for larger merchants. Push for the full fee schedule in writing regarding MDR, platform fees, GST implications, and volume tiers.
- Use it selectively at first. UPI Credit Line earns its MDR on high-value transactions where credit availability drives conversion. For sub-₹500 purchases, standard UPI is still the right tool.
- Track costs at the transaction level. Looking only at total settlements masks what’s happening by payment method. Break it down. Know exactly what UPI Credit Line costs versus what it contributes.
- Evaluate PSPs on total cost, not headline MDR. Lower MDR from a gateway with poor success rates and no automation will cost more in operations than the rate difference saves. The full picture matters.
- Choose cost-effective solutions without compromising on quality, backed by lifetime after-installation support. Credit-linked payment infrastructure has moving parts because ongoing support isn’t optional; it’s the baseline.
Conclusion
UPI Credit Line brings together the speed of UPI and the flexibility of credit into one checkout experience.
For customers, it removes the friction of limited bank balances on high-value purchases. For merchants, it means access to a segment of buyers who spend more, convert better, and return more often.
As UPI continues to scale, expectations around payment flexibility are changing just as fast. Credit on UPI helps customers to make larger purchases feel easy and accessible.
For merchants, this isn’t just about adding another payment method. It’s about keeping up with how people want to pay today. Those who adapt early are better positioned to capture demand, improve customer experience, and stay relevant as digital payments continue to evolve.
FAQs
1. What are the charges for UPI Credit Line for merchants?
Merchants pay an MDR typically between 1.3% and 2% of the transaction value, plus platform fees charged separately by the payment gateway.
2. Is UPI Credit Line interest-free for customers?
Some banks offer an interest-free grace period similar to a credit card cycle; others accrue interest from day one; it depends entirely on the bank’s product terms.
3. What is the MDR on UPI Credit Line transactions?
NPCI’s confirmed rate sits at 1.3% for most merchant categories, with some variation by Merchant Category Code. That’s lower than credit cards (which can reach 3%) but higher than the zero-MDR applicable to standard bank-account UPI.
4. Who pays the UPI Credit Line fee—the merchant or the customer?
The merchant pays the MDR; it is a merchant-side charge, structured similarly to credit card acceptance fees.
5. How is UPI Credit Line different from regular UPI in terms of fees?
Standard UPI draws from a bank balance and carries zero MDR; UPI Credit Line draws from borrowed funds, which introduces credit risk and triggers MDR.
6. Can merchants negotiate UPI Credit Line fees?
Yes. High-volume merchants can negotiate MDR rates with PSPs and banks; smaller merchants have less leverage but can still compare providers on total transaction cost.
7. Is UPI Credit Line different from RuPay Credit Card on UPI?
Yes. RuPay Credit Card on UPI is a physical card linked to UPI, whereas UPI Credit Line is a pre-approved bank credit limit tied directly to a UPI ID.
8. Should small merchants accept UPI Credit Line payments?
It makes most sense for higher-ticket transactions where credit access improves conversion; for very low-value purchases, zero-MDR standard UPI is still the better call.
