A no-cost EMI lets you split a purchase into equal monthly instalments with no interest shown on the bill. It is rarely truly free – the interest usually hides as a discount you give up, 18% GST still applies on that interest, and a processing fee often creeps in. You pay for the convenience of spreading the cost; you just don't see the line item.
The pitch is clean: buy a ₹40,000 phone today, pay about ₹6,667 a month for six months, and the shop tells you the interest is zero. Someone is still funding those instalments, though. A lender advances the money and expects a return. In a no-cost EMI, that return doesn't vanish – it gets moved somewhere you're less likely to notice.
Where a 'no-cost' EMI still costs you
What is a no-cost EMI, really?
A no-cost EMI (sometimes called a zero-cost or 0% EMI) splits the price of a purchase into monthly instalments and advertises no interest on top. The RBI has flagged the name as a misnomer (its 2013 circular said there is no such thing as a zero-percent interest scheme) – a loan carries a cost, and that cost has to sit somewhere. It usually sits in one of two places.
In the first structure, the seller funds a discount equal to the interest the bank charges. The bank still earns its interest; you get a matching discount, so the two cancel and your total looks like the sticker price. In the second, the product is billed at full price and the discount you would have got for paying upfront is quietly withheld – that withheld discount is the interest, renamed.
Where's the catch?
Three places the cost hides:
- The discount you give up. Many products carry an instant discount if you pay in full. Choose the no-cost EMI and that discount often disappears. You pay the full price, and the gap between the full price and the discounted price is the interest by another name.
- GST on the interest. Even when the interest is rebated back to you, GST at 18% is charged on that interest component – and it is usually not reversed. On a ₹30,000 purchase over six months, the interest baked in might be around ₹1,000 to ₹1,500 (illustrative); 18% GST on that is a couple of hundred rupees you pay out of pocket.
- Processing and foreclosure fees. Some lenders add a one-time processing fee. And if you want to clear the instalments early, foreclosure charges may apply, so paying it off ahead of schedule isn't always free either.
Does a no-cost EMI affect your credit score?
On a credit card, a no-cost EMI usually blocks the outstanding EMI amount, released as you pay each instalment. Buy a ₹40,000 item on a ₹1,00,000 card and that amount is blocked at first, freeing up as each instalment is billed – which pushes up your credit utilisation, one of the biggest inputs into your CIBIL score. Keeping utilisation under about 30% is a common rule of thumb, and a large blocked EMI can quietly break it. The instalment itself, paid on time, doesn't hurt; the squeezed limit can.
When does a no-cost EMI actually make sense?
This is a mechanism, not a mistake. A no-cost EMI can be a reasonable way to spread the cost of a planned, genuinely needed purchase – if three things hold: you would have paid the full price anyway, so there's no discount being quietly withdrawn; you can cover every instalment comfortably; and you've counted the GST and any fee into the real cost.
The trap is behavioural, not mathematical. "No-cost" is designed to make a bigger purchase feel painless, so the risk is that it nudges you into buying something you hadn't planned to. The useful question isn't "what's the interest rate" – it's "was I going to buy this anyway." A flat-looking rate can also mask a much higher effective one; the same trick sits behind flat versus reducing interest rates.
A no-cost EMI isn't a scam, but the name does a lot of the selling. Read it as interest you can't see, add back the GST and any fee, and it becomes what it always was – a way to borrow. Useful when the purchase was already decided. Expensive when the offer does the deciding.
