Key Takeaways & Summary
  • RBI strictly prohibits banks from offering true 0% interest loans; "No Cost EMI" is an upfront merchant discount.
  • The merchant discounts the product price by the exact interest amount the bank will charge you over the tenure.
  • Hidden Catch: You must pay 18% GST on the monthly interest component, meaning it is NEVER 100% cost-free.
  • Banks often charge a one-time non-refundable EMI processing fee of ₹99 to ₹199 + GST.

Whenever a major festival sale launches on Amazon or Flipkart, "No Cost EMI" banners are plastered across every smartphone, laptop, and television. But in banking, there is no such thing as free money. In 2013, the Reserve Bank of India officially banned zero-percent interest schemes.

How No Cost EMI Actually Operates

Because banks cannot lend money at 0% interest, retailers use a clever accounting workaround: Upfront Discounting.

If a phone costs ₹60,000 and the bank charges 15% interest for a 6-month EMI (which equals ₹2,600 interest), the merchant discounts the phone price to ₹57,400 at checkout. The bank then finances ₹57,400 at 15% interest, making your total monthly payments equal exactly ₹60,000.

The 2 Hidden Costs You Must Pay

  1. 18% GST on Interest: Under Indian tax law, bank interest charges on consumer credit cards attract 18% GST. Even though the merchant subsidized the interest, the GST (around ₹400 to ₹800) is paid out of your pocket.
  2. One-Time Processing Fee: Almost all credit card issuers (HDFC, ICICI, SBI Card, Axis) deduct a non-refundable convenience fee of ₹99 to ₹199 + GST on every EMI conversion.

Frequently Asked Questions

Is No Cost EMI completely free of extra cost?

No. While the merchant discounts the base product price to offset the bank interest, you are still legally required to pay 18% GST on the interest charged by the bank every month, plus a one-time processing fee.

Does opting for No Cost EMI block my credit card limit?

Yes. The full purchase amount is blocked against your credit card limit immediately, and your available limit is restored incrementally as you pay off each monthly EMI installment.
