"No-cost EMI" is on almost every big purchase this festive season: phones, laptops, TVs, fridges. Pay ₹10,000 a month for six months instead of ₹60,000 today, and pay "nothing extra". It sounds like free money.

It's close, but it isn't free. Here's what no-cost EMI really means, where the hidden charges are, and how to tell whether a no-cost EMI deal is actually a good one.

What does no-cost EMI mean?

No-cost EMI means you pay for a product in equal monthly instalments that add up to its price, with no extra interest showing in your EMIs.

But the bank doesn't lend for free. Here's what actually happens:

1. The bank still charges interest on the EMI at its usual rate.

2. The seller or brand gives you a discount equal to that interest, usually upfront on the price.

3. The discount cancels out the interest, so your EMIs add up to the original price.

So the interest is still there. Someone else (usually the brand) pays it for you.

Is no-cost EMI really free?

Almost, but not quite. There are three costs the discount doesn't cover:

What no-cost EMI really costs: a worked example

Say you buy a ₹60,000 phone on a 6-month no-cost EMI. At an illustrative bank rate of 16% a year and a ₹199 processing fee (your bank's numbers will differ):

That's about 1.2% of the price. It's far cheaper than a regular EMI or revolving your card balance, but it isn't zero.

Now compare it with paying upfront. If paying in full on the same day gets you, say, a ₹3,000 instant discount that isn't available on EMI, then no-cost EMI actually costs you about ₹3,700 more than paying upfront.

What the RBI rules say

Under the RBI's credit card rules, card issuers must:

• Clearly show the principal, interest and any upfront discount that makes it no-cost, before you convert to EMI

• Show the same breakup separately on your credit card statement

• Not pass off an EMI with an interest component as "zero-interest" or "no-cost"

So if your statement shows interest that wasn't offset by a discount, raise it with your bank.

Other things to watch with no-cost EMI

• Your credit limit gets blocked. The full purchase amount is blocked from your available limit and freed up as you pay each EMI. That raises your credit utilisation until it's repaid.

• Rewards may not apply. Many cards don't give reward points or cashback on amounts converted to EMI.

• Closing early can cost you. If you pay off the EMI early, the bank may charge a foreclosure fee, and you could lose part of the no-cost benefit.

• A missed EMI costs a lot. It's treated like any missed card payment: a late fee, interest and a possible hit to your credit score.

When no-cost EMI makes sense

It's a good deal when:

• There's no bigger discount for paying in full

• The processing fee is low or waived

• You'd otherwise have to dip into savings or carry a card balance

• The EMI fits comfortably in your monthly budget

Think twice when:

• Paying upfront gets you a bigger instant discount or cashback

• The processing fee and GST make a short-tenure EMI relatively expensive

• You're already using a large part of your credit limit

How to check if a no-cost EMI is really no-cost

1. Compare the final price for EMI against the price for paying in full, including any instant discounts.

2. Ask about the processing fee before you confirm.

3. Read the EMI breakup the bank shows you: principal, interest and discount.

4. Check your next statement to make sure the interest is offset and only GST (and any fee) remains.

5. Check whether you'll lose rewards on the purchase.

FAQs

What does no-cost EMI mean?

It means you pay a product's price in equal monthly instalments with no extra interest in your EMIs. The bank still charges interest, but the seller gives you an equal discount, so the two cancel out.

Is no-cost EMI really free?

Not completely. You usually pay 18% GST on the interest component, often a processing fee plus GST, and you may give up a discount you'd get by paying in full.

Why is GST charged on no-cost EMI?

Because the bank still charges interest, and GST at 18% applies to that interest. The no-cost discount covers the interest, not the GST.

Is no-cost EMI better than paying upfront?

Only if paying upfront doesn't get you a bigger discount. Compare the total cost of both options, including GST, the processing fee and any instant discounts.

Does no-cost EMI affect my credit score?

Not by itself, and paying EMIs on time helps your repayment record. But the blocked limit raises your credit utilisation, and a missed EMI is reported like any missed card payment.

Can I close a no-cost EMI early?

Usually, yes, by paying the remaining principal. Your bank may charge a foreclosure fee, and you could lose part of the no-cost benefit, so check the terms first.

Do I earn reward points on a no-cost EMI purchase?

It depends on your card. Many cards don't give rewards on amounts converted to EMI.
