Understanding the True Cost: A Breakdown of MDR, TDR, and Other Hidden Fees

The first step in choosing a payment gateway for Indian ecommerce is looking beyond the headline rate. The true cost of processing payments is a combination of several fees, often intentionally obscured. The most significant is the Merchant Discount Rate (MDR), a percentage fee charged on every single transaction. This isn't a flat rate; it varies significantly based on the payment mode. For example, a gateway might charge 1.8% for domestic credit cards, 1.5% for UPI, 0.4% for debit cards (for transactions below ₹2000), and up to 3% for international cards or wallets. Always remember that GST at 18% is applicable on top of these fees, which many merchants forget to factor in.

Next is the Transaction Discount Rate (TDR), which is often used interchangeably with MDR, but can sometimes refer to the complete package of fees. Beyond this, look for other charges. Is there a one-time Setup Fee? This can range from zero to ₹30,000, depending on the provider and the scale of your business. Is there an Annual Maintenance Charge (AMC)? Many modern gateways have waived this for small businesses, but enterprise plans might still include it. Also, investigate fees for chargebacks, batch settlements, and fund transfers to your bank account. A gateway might offer a low MDR but charge a fixed fee on every settlement, eating into your margins.

A common mistake is to only compare the credit card MDR. For most Indian businesses, UPI and debit card transactions form the bulk of the volume. A gateway with a slightly higher credit card rate but zero fees on UPI could be far more cost-effective. Always analyze your expected transaction mix.

Finally, consider withdrawal fees and settlement cycles. While most gateways now offer T+1 or T+2 day settlements (transaction day plus one or two days), faster, same-day, or on-demand settlements often come at a premium. These "hidden" costs are where profitability is often won or lost.
