Understanding Transaction Fees & Charges

Every time a customer pays you online — whether via UPI, credit card, or netbanking — a slice of that payment goes to the payment gateway, the card network, and the issuing bank. These are transaction fees, and they are the invisible tax on every sale. For most Indian e-commerce sellers, payment gateway charges consume 2–3% of gross revenue (Enkash, 2025). On ₹10 lakh in monthly sales, that is ₹20,000–30,000 going to payment processing before you count shipping, packaging, or your own margins.

The good news: India's payment ecosystem is one of the most competitive in the world. UPI's zero-MDR policy, multiple gateway providers fighting for market share, and RBI regulations keeping fees transparent mean you have real options. This guide breaks down exactly what you pay, to whom, and how to minimise those costs without sacrificing the customer's checkout experience.

How Payment Gateway Fees Work

When a customer pays ₹1,000 on your store, the money does not go directly from their bank to yours. It passes through a chain: the payment gateway (Razorpay, PayU, Cashfree), the card network (Visa, Mastercard, RuPay), and the issuing bank. Each takes a cut. The total fee you see on your dashboard — typically 2% + GST — is the combined cost of all these intermediaries.

• Payment Gateway Fee (Platform Fee) — The charge from Razorpay, PayU, or Cashfree for processing the transaction. This is the fee you negotiate directly.
• MDR (Merchant Discount Rate) — The interchange fee that goes to the card-issuing bank and the card network. For cards, this is bundled into the gateway fee. For UPI, RBI has mandated zero MDR since January 2020.
• GST on Fees — All payment gateway fees attract 18% GST. So a 2% gateway fee is actually 2% + 0.36% = 2.36% of the transaction value. This GST is claimable as input tax credit if you are GST-registered.

Payment Gateway Comparison: Razorpay vs PayU vs Cashfree

India has three dominant payment gateways for e-commerce sellers. As of 2025, here is how their standard pricing compares (Razorpay Pricing Page, 2025; Enkash Payment Gateway Comparison, 2025; The DM School Cashfree Review, 2025):

PayU charges around 2% + GST for domestic transactions (Digital Payment Guru, 2025). Stripe is available in India but with limited access — it is primarily used by businesses with international operations and charges 2% for domestic and 3% for international transactions, with settlements taking 2–7 days (Enkash, 2025).

Breaking Down Fees by Payment Method

UPI — The Best Deal for Sellers

UPI is unique. The Reserve Bank of India mandated zero MDR on UPI transactions from January 1, 2020 — meaning no interchange fee is charged to merchants. However, payment gateways still charge a platform fee for processing UPI transactions. On Razorpay, UPI is charged at 2% + GST at standard rates, but with tiered pricing: once your cumulative UPI sales cross ₹25 lakh, the platform fee drops. On Cashfree, UPI can be as low as 0% to 0.4% depending on volume and agreement terms (The DM School, 2025).

UPI crossed 16.73 billion transactions in December 2024 alone (NPCI data), making it the dominant payment method in India. For most e-commerce stores, 40–60% of prepaid orders come through UPI. Negotiating a lower UPI rate with your gateway provider is one of the highest-impact cost optimisations you can make.

Credit and Debit Cards

Domestic credit and debit cards are charged at the standard gateway rate — 2% + GST on Razorpay, 1.95% + GST on Cashfree. RuPay debit cards benefit from zero MDR (like UPI), but the gateway platform fee still applies. International cards (Visa, Mastercard issued outside India) are charged at premium rates — typically 3% + GST — because of cross-border interchange fees and currency conversion costs.

Netbanking and Wallets

Netbanking transactions are charged at the standard domestic rate (2% + GST on Razorpay). Wallets like Paytm Wallet, PhonePe Wallet, and Amazon Pay are also at standard rates. EMI transactions (credit card EMI, debit card EMI, cardless EMI) are charged at premium rates — typically 3% + GST — because of the additional credit risk and processing involved.

Understanding Settlement Timelines

Settlement is when the money from customer payments actually arrives in your bank account. This is not instant — there is always a delay:

• T+2 (Razorpay, PayU standard) — If a customer pays on Monday, the money settles in your bank account by Wednesday. This is the most common settlement cycle for Indian payment gateways.
• T+1 (Cashfree standard) — Money settles the next business day. This is Cashfree's key differentiator and can meaningfully improve cash flow for high-volume sellers.
• Instant Settlement (1% extra) — Both Razorpay and Cashfree offer instant or same-day settlement for an additional 1% fee on top of the transaction charge. Use this selectively — for example, during cash-tight periods — not as a default.
• Weekends and Holidays — Settlements do not process on bank holidays. A Friday transaction on T+2 settles on Tuesday, not Sunday.

“Settlement speed is cash flow speed. A T+1 settlement means you can reinvest customer payments into inventory, advertising, or operations a full day faster. Over a year, that compounding advantage is significant — especially for fast-growing stores.”

Hidden Costs Most Sellers Miss

The headline transaction fee is not the only cost. Watch for these additional charges that can quietly eat into your margins:

• Refund processing — When you refund a customer, most gateways do NOT refund the transaction fee. You paid 2% + GST when the sale happened, and you do not get that back when the sale is reversed. On a ₹1,000 order, you lose ₹23.60 in fees even though you returned the full ₹1,000 to the customer.
• Chargeback fees — If a customer disputes a transaction with their bank (chargeback), the gateway charges a penalty — typically ₹150–300 per chargeback on Razorpay. Win or lose the dispute, the fee applies.
• International currency conversion — For international payments, there is a currency conversion spread on top of the 3% gateway fee. The actual exchange rate used is typically 1–2% worse than the mid-market rate.
• Payment link fees — Razorpay charges the same transaction fee on payments collected via payment links (shared on WhatsApp, SMS, etc.). There is no additional fee for creating payment links, but the transaction cost applies when the customer pays.
• Subscription/recurring payment fees — Automated recurring charges (for subscription boxes or SaaS) may have slightly different fee structures. Check with your gateway provider.

How to Reduce Your Payment Processing Costs

• Negotiate volume-based rates — If you process more than ₹5 lakh per month, contact your gateway provider and ask for custom pricing. Most gateways offer 1.5–1.8% rates for high-volume merchants. The rate card on the website is the starting point, not the final price.
• Push UPI adoption — UPI has the lowest effective cost for most sellers. Display UPI prominently at checkout ("Pay via UPI — fastest checkout"), offer a small discount for UPI payments, or set UPI as the default payment option.
• Minimise international card payments — If your customers are primarily domestic, ensure your checkout does not accidentally route domestic cards through international processing (which happens with some card BINs). Razorpay handles this automatically, but verify.
• Reduce refunds — Every refund costs you the transaction fee. Invest in accurate product descriptions, size guides, and quality control to reduce the return rate. Each percentage point of return reduction saves direct gateway fees.
• Claim GST input credit — The 18% GST on payment gateway fees is eligible for input tax credit. Ensure your accountant claims this in your GST returns — it effectively reduces the gateway cost by the GST component.
• Avoid instant settlement unless necessary — The extra 1% for instant settlement is expensive. Use it only during genuine cash flow crunches, not as a default setting.

Passing Fees to Customers: Should You?

Some sellers add a "payment processing fee" or "convenience fee" at checkout to recover gateway costs. This is legal in India (unlike in some countries where surcharging is banned), but it has trade-offs:

• Arguments for — It recovers a real cost. A 2% convenience fee on online payments can offset your entire gateway bill. Some sellers apply it only to credit cards (which have the highest fees) and waive it for UPI.
• Arguments against — It creates friction at checkout. A SellersCommerce 2025 report found that 47% of shoppers abandon carts when they encounter unexpected costs at checkout. A surprise fee at the payment step is exactly the kind of cost that triggers abandonment.
• The middle path — Build the transaction fee into your product pricing (increase prices by 2–3%) and advertise "no hidden charges at checkout." The customer pays the same total, but the experience feels cleaner.

“The best-run e-commerce businesses treat payment gateway fees the same way they treat rent or packaging — as a cost of doing business that is factored into pricing, not passed on as a visible surcharge. Your customers should never feel punished for choosing to pay you.”

Reading Your Payment Dashboard

Commerce Synapse provides a payment reconciliation dashboard (powered by Razorpay) that tracks every transaction. Here is what to monitor monthly:

• Gross transaction value (GTV) — Total payments collected before fees. This is your top-line number.
• Total fees deducted — The sum of all gateway fees + GST on fees. Divide this by GTV to get your effective fee rate. If it is above 2.5%, investigate — you may be processing too many international or EMI transactions.
• Net settlement amount — What actually hits your bank account. GTV minus fees minus refunds. This is the number that matters for cash flow planning.
• Payment method mix — What percentage of payments come through UPI, cards, netbanking, and wallets? If UPI is below 40%, consider promoting it at checkout.
• Refund deductions — Total fees lost to refunds. Track this monthly and correlate it with your return rate.
• Failed transaction rate — Payments that were attempted but failed (network errors, insufficient funds, OTP failures). A rate above 5% suggests checkout UX issues.

Wrapping Up

Transaction fees are one of those costs that feel small per order but compound into serious money over a year. On ₹50 lakh in annual sales, a 2% gateway fee means ₹1 lakh going to payment processing — and that is before GST on fees, refund losses, and chargebacks. Understanding exactly where that money goes is the first step to controlling it.

The playbook is straightforward: negotiate volume rates once you cross ₹5 lakh monthly, push UPI adoption at checkout, claim GST input credits on gateway fees, and reduce refunds through better product listings. Commerce Synapse shows you the full breakdown in your payment dashboard — use it monthly to track your effective fee rate and ensure you are not leaving money on the table. In e-commerce, margins are won in the details, and payment processing is one of the biggest details most sellers overlook.
