No. A no cost EMI usually cancels the interest with an upfront discount, but on a credit card you still pay 18% GST on that interest, and any processing fee with GST on it too. On a ₹1,50,000 laptop over six months that adds about ₹1,500, and a table by salary further down shows whether the money you keep invested earns it back.

Why is a no cost EMI not completely free?

There is still a loan, with interest. In a September 2013 circular, RBI said that "the very concept of zero percent interest is non-existent", and that in zero-interest EMI schemes on card outstandings the interest was often hidden in a processing fee.

RBI's card directions of November 2025 allow the offer but set the terms: before converting a purchase, the card-issuer must show the principal, the interest and the upfront discount from the merchant or issuer that makes it no cost, and show them again on the statement. An EMI with interest in it cannot be passed off as zero-interest.

So the seller or the card-issuer gives a discount equal to the interest, the bank lends the rest, and your EMIs add up to the sticker price.

The hidden charges are what the discount does not cover: GST on interest and the processing fee. Interest on loans is exempt from GST, but the exemption excludes interest involved in credit card services, so a credit card EMI carries 18% GST on its interest (2026). A processing fee carries 18% too. A no cost EMI on a consumer loan or a debit card carries no GST on its interest, only on its fee.

What does Neha's ₹1,50,000 laptop actually cost?

Neha earns ₹22 lakh CTC, about ₹1,41,000 a month in hand, and buys a ₹1,50,000 laptop on a no cost EMI on her credit card: six EMIs of ₹25,000.

Card-issuers set their own EMI rates, usually 12% to 24% a year (2025), and processing fees: usually a flat few hundred rupees, nil on some offers, though some charge 1% to 3% of the amount. Neha's card charges 15% a year, 1.25% a month. Six EMIs of ₹25,000 at that rate repay a loan of ₹1,43,650, so that is what the bank lends. The upfront discount fills the gap, ₹6,350, exactly the interest she pays over the six months.

The extra cost:

Item Working Amount
Interest covered by the discount ₹0
GST on interest 18% of ₹6,350 ₹1,143
Processing fee her card's fee ₹299
GST on the fee 18% of ₹299 ₹54
Total over the price ₹1,496

That is about ₹1,500, or 1% of the laptop. To price your own offer, read the interest on the conversion screen: your cost is 18% of that interest, plus the fee and 18% on the fee. A 1% fee alone would cost ₹1,770 with GST, more than any row below earns.

Does the money you keep invested cover the cost?

Paying in full by card, Neha would clear ₹1,50,000 on her next due date. The EMI route lets her keep ₹1,25,000 for one more month, then ₹1,00,000, down to ₹25,000. That money held back, the float, comes to ₹31,250 for a year. In a liquid fund at an assumed 6% a year (2026), it earns ₹1,875 before tax.

Slabs on the new regime for FY 2026-27, from the structure in CTC vs in hand salary, PF on full wages:

CTC Slab with 4% cess Float earned after tax Against the ₹1,496 cost
₹15 lakh 15.6% ₹1,583 ₹87 ahead
₹22 lakh 20.8% ₹1,485 ₹11 behind
₹25 lakh 26% ₹1,388 ₹108 behind
₹40 lakh 31.2% ₹1,290 ₹206 behind

For Neha, in the 20% slab, the float and the cost cancel out. In a savings account at 3% (large banks paid about 2.5% to 3.5% in 2026), she would be about ₹750 behind, and at 2.5% about ₹880.

When does paying in full win?

Paying in full wins when the seller gives a discount for it. If the no cost offer excludes, say, ₹3,000 off for paying in full, that is twice the whole GST and fee: her real cost becomes ₹4,496, and no float covers that.

It also wins when the card's rate is higher. If a card quotes 18% for six months, the interest is ₹7,570 and the GST ₹1,363, so with the fee Neha pays ₹1,716 against the ₹1,485 her money earns. A longer tenure cuts the other way: over 12 months at 15% the GST and fee come to ₹2,425, but she keeps ₹68,750 for a year, which earns about ₹3,270 after tax, about ₹840 more. For a larger sum over a longer term, a personal loan vs a loan on your credit card compares the two routes.

Does a no cost EMI block your limit or lose reward points?

The converted amount usually stays blocked against your credit limit until it is repaid. Your card's terms decide whether an EMI purchase still earns points, and what reward points are worth shows how to value them. A missed EMI becomes an unpaid card bill at card rates; paying only the minimum due shows how fast that grows.

Frequently asked questions

It can, through how much of your limit you use: the converted amount usually stays blocked until the EMIs run down, so a large purchase raises your credit utilisation, which credit scores take into account. Paying each EMI by the due date keeps your repayment record clean.
Usually yes, by paying the principal still owed. The card's terms set any foreclosure charge, and 18% GST applies to that charge. The upfront discount was sized for the full tenure, so ask the issuer whether any of it is reversed before you close.
Because there is a loan, and the card-issuer must show its interest separately. Usually the purchase is converted at the discounted amount, ₹1,43,650 on a ₹1,50,000 laptop over six months at 15%, and the interest brings the EMIs back to the price; if instead the full price is converted and the discount credited back, the GST is about ₹50 higher. The GST on that interest is billed with each EMI, ₹323 in the first month in that example.
