"No-Cost EMI" is everywhere on Amazon, Flipkart and at electronics stores — and it sounds too good to be true: buy now, pay in instalments, zero interest. But is it actually free? The honest answer is: almost, but not quite. Here's exactly how it works and where the hidden costs hide.
How No-Cost EMI Actually Works
Banks aren't allowed to lend at 0% — the RBI requires interest to be disclosed. So no-cost EMI works through a clever offset:
- The bank charges normal EMI interest (around 13%–16% p.a.) on your purchase.
- The merchant or brand gives you an upfront discount equal to that interest.
- The discount and the interest cancel out — so your total payout roughly equals the product's price.
That's why it's "no-cost": you don't pay interest on the principal. But two charges survive this offset.
Hidden Charge #1 — GST on Interest (18%)
Even though the interest is "waived", the government still levies 18% GST on the interest component. This is non-refundable and not covered by the merchant discount.
| Purchase | Tenure | Approx. GST on interest |
|---|---|---|
| ₹30,000 | 6 months | ~₹230 |
| ₹60,000 | 6 months | ~₹450 |
| ₹1,50,000 | 9 months | ~₹1,700 |
Hidden Charge #2 — Processing Fee
Many banks add a one-time processing fee of ₹199–₹499 + GST per EMI conversion. On smaller purchases this single fee can be a meaningful percentage of the benefit.
Hidden Cost #3 — Lost Cashback & Rewards
Most cards don't give cashback or reward points on EMI transactions. If your card normally earns 1–2% back, that's ₹500–1,200 of lost rewards on a ₹30,000–₹60,000 purchase — a real, if invisible, cost.
Hidden Cost #4 — Blocked Credit Limit
The entire purchase amount is blocked against your credit limit for the whole tenure — not just the monthly instalment. A ₹60,000 EMI on a ₹2 lakh limit instantly pushes your utilisation to 30%, which can affect your CIBIL score and your ability to make other purchases.
So — Is It Worth It?
Use no-cost EMI when:
- You're buying a big-ticket item you genuinely need and can repay comfortably.
- The GST + processing fee is small relative to the amount.
- You'd rather preserve cash flow than pay the full price upfront.
Avoid it when:
- It's tempting you into a purchase you wouldn't otherwise make.
- The fees and lost rewards wipe out the convenience.
- You're already running high credit utilisation.
