No-cost EMI: is it really free?

Short answer: Usually close to free, rarely completely free. With a “no-cost EMI”, the lender still charges interest. The shop or brand gives you a discount of the same amount, so your EMIs (monthly payments) add up to the price. You may still pay a processing fee and, on credit cards, 18% GST on the interest. You may also lose a cash discount you’d get for paying in full. So compare the total of your EMIs plus fees with the best price you could pay today.
The situation
It’s a festival sale. Kiran sees a ₹30,000 phone: “No-cost EMI, 6 months, just ₹5,000 a month!” The same page says: “₹1,500 instant discount on full payment with selected cards.” Which is cheaper?
How “no-cost” works
- The lender gives you a loan with interest. The lender is your card company, or an NBFC (a finance company that is not a bank) for loans on goods like phones and TVs.
- The brand or shop gives a discount equal to that interest. This is called subvention.
- Your EMIs add up to the price on the label, so the interest seems to disappear.
RBI rules say a card company must show you the principal, the interest and the discount before it turns a purchase into EMIs, and again on your statement. It must not use the words “no-cost” to hide the interest.
On paper, the interest is still there, and you pay for it in other ways:
- On credit cards, 18% GST is charged on the interest part of each EMI. You don’t get it back. (Interest on ordinary loans has no GST, but card interest does.)
- There’s often a processing fee of a few hundred rupees, plus 18% GST.
- If you choose EMI, you may not get the cash discount for paying in full.
Kiran’s numbers
Fictional example: card EMI at 15% a year for 6 months, processing fee ₹199 + GST. Figures calculated by Paisavy.
| Pay in full | “No-cost” EMI on a card | |
|---|---|---|
| Price | ₹30,000 | ₹30,000 (6 × ₹5,000) |
| Cash discount | − ₹1,500 | — |
| Hidden interest (covered by the discount) | — | ₹1,270 |
| GST on that interest (18%) | — | + ₹229 |
| Processing fee incl. GST | — | + ₹235 |
| You pay | ₹28,500 | ₹30,463 |
The “no-cost” EMI costs ₹1,963 more than paying in full with the discount. Without the cash discount, the gap would be only ₹463, about 1.5% of the price.
Card EMI or an NBFC loan?
| Card EMI | Consumer-durable loan (NBFC “EMI card”) | |
|---|---|---|
| GST on interest | Yes, 18% | No |
| Processing fee | Often, + GST | Often, + GST |
| Key Facts Statement (KFS) | No loan KFS, but the card company must show the principal, interest and discount before conversion | Required, with APR |
| Down payment / advance EMI | Rare | Sometimes |
| Credit report | Uses your card limit | Shows as a separate loan |
A consumer-durable loan is a loan for goods like phones, fridges and TVs. The KFS is a short summary of the loan’s costs, and the APR is the yearly cost including fees.
Both options are credit. If you miss an EMI, it goes on your credit report. You may pay late fees, and the “no-cost” offer may stop.
When it makes sense, and when it doesn’t
No-cost EMI can work when:
- the shop gives no discount for paying in full, so you only pay extra for the fee and GST
- the EMI fits even your weak month (see Can I afford this purchase?)
- otherwise you’d have to use savings you keep for an emergency.
Think twice when a cash discount is bigger than the fees and GST, or when you already have several EMIs or a card balance you’re not clearing. And if you don’t need the item now, saving for a few months costs nothing.
Questions to ask before you choose
- What’s the full-payment price today, after every discount?
- What’s the processing fee, and is GST extra?
- For card EMI: how much GST on interest will appear on my statements?
- For a loan: can I see the KFS and APR? Is there a down payment or advance EMI?
- What happens if I close it early or miss a payment?
What to check today
- Add up EMIs + fee + GST and compare the total with the best pay-now price.
- Check the EMI against your weak month with the Can I afford it? tool.
- If you already have a no-cost EMI, look for “GST on interest” lines on your card statement.
