How "No Cost EMI" Actually Works in India
When you buy a product on No Cost EMI, the bank or NBFC converts the purchase into equated monthly instalments at 0% interest. That sounds free — but there is always a processing fee, typically 1.5% to 3% of the purchase price. This fee is deducted upfront or added to the first EMI. Since the fee is proportional to the price and tenure, it functions exactly like interest — it is just not called that.
For example, a ₹50,000 phone on 12-month No Cost EMI with a 2% processing fee costs you ₹1,000 extra. Add 18% GST on that fee (₹180), and you have paid ₹1,180 more than the cash price. The effective annual rate works out to roughly 3.7% — not zero.
Why Banks Can Legally Call It "0% Interest"
RBI regulations require transparency on interest rates, but processing fees fall outside the "interest" definition. Banks and NBFCs exploit this loophole: they set the interest rate to 0% and recover their cost through the processing fee instead. Since the fee is disclosed (usually in small print), it is technically legal. The result is that consumers see "0% EMI" in big bold text and miss the fee buried in the terms and conditions.
- Processing fee: 1-3% of purchase price, charged upfront. This is the hidden interest.
- GST on processing fee: 18% GST is charged on the fee itself, adding another layer of cost most people miss.
- Subvention model: Some sellers absorb the processing fee to offer truly zero-cost EMI. These are rare and usually during festive sales.
When Should You Use No Cost EMI?
No Cost EMI is not always bad — it depends on the fee and what you would do with the cash. If the processing fee is under 1% and you can invest the cash in a liquid fund earning 7%+, the EMI option actually works in your favour. But if the fee is 2-3% on a short tenure, you are better off paying cash and avoiding the extra cost entirely.
- Use EMI when:the processing fee is very low (<1%), the tenure is long (18-24 months), and you can invest the cash meanwhile.
- Pay cash when: the processing fee is 2%+ on a short tenure (3-6 months), or the product is under ₹15,000 — the fee plus GST is not worth the hassle.
- Always check: whether the seller is absorbing the fee (truly free) or passing it to you (hidden cost).
