No Cost EMI and EMI on Debit Card: What a ₹60,000 Phone Really Costs

Jay in Jamnagar had the phone in his cart by the second day of the Diwali sale. ₹60,000, and right under the price, a green line: "No Cost EMI ₹6,667 × 9". His salary was ₹45,000 a month, the phone was not urgent, but ₹6,667 a month looked like nothing. He tapped it, picked his credit card, and the order went through in under a minute. The small print under the green line, the one that said "GST on interest will be charged by the bank", he never opened.

Nine months later Jay had paid ₹60,939 for a ₹60,000 phone, and had missed a ₹1,500 instant discount that cash buyers got on the same page. Still a decent deal next to a regular credit card EMI, which would have cost about ₹64,800. But it is not zero, and the "no cost" label hides where the money goes. Here is the full working, every number from the site's EMI calculator.

No cost EMI meaning: who is actually paying the interest

A bank does not lend ₹60,000 for nine months for free. In a no-cost EMI there are three parties, and the interest moves between them like this:

• The bank charges its normal EMI interest, say 15% a year, on a reducing balance. Nothing changes on its side.
• The seller or the brand gives you a discount at checkout that is exactly equal to that interest. Flipkart's own no cost EMI terms put it plainly: you get "an upfront discount equal to the EMI interest cost charged by the bank", the discount comes from the seller, and the bank then charges interest on a monthly reducing basis.
• You repay the discounted amount plus the bank's interest, which adds back up to the sticker price. So nine EMIs of ₹6,667 come to ₹60,000, and the word "interest" never appears on the product page.

This structure exists because of a rule. In September 2013 RBI told banks to stop "zero percent" schemes where the interest was hidden in a processing fee, and said that any discount on the product must reduce the loan amount itself (RBI circular RBI/2013-14/292 of 17 September 2013). The 2022 Master Direction on credit and debit cards (para 6(b)(iii)) goes a step further: before any card transaction is converted to EMI, the card issuer must show you the principal, the interest and the upfront discount given by the merchant or the issuer "to make it no cost", and the same split must appear on your statement. An EMI with an interest component "shall not be camouflaged as zero-interest/no-cost EMI". That is why the bank's EMI confirmation always has an interest line. The discount is on the merchant's side, the interest is on the bank's side, and the GST follows the interest.

The maths on Jay's ₹60,000 phone

Assume the bank's EMI rate is 15% a year, reducing balance, for 9 months. First, what a plain EMI on ₹60,000 looks like, from the calculator:

Now the no-cost version. The seller has to find a discount such that the EMI becomes exactly ₹60,000 ÷ 9 = ₹6,667. Work backwards: which loan amount gives an EMI of ₹6,667 at 15% for 9 months? The answer is ₹56,416. So the checkout shows a discount of ₹3,584, the bank lends ₹56,416, charges ₹3,584 as interest over nine months, and you pay ₹6,667 × 9 = ₹60,000. Here is the bank's side, month by month:

Loan ₹56,416 at 15% reducing, 9 EMIs of ₹6,667. The discount (₹3,584) is a little less than the interest on the full ₹60,000 (₹3,812) because the bank is lending less. The seller pays for exactly the interest, not a rupee more. And that last column is the first real cost.

The 18% GST that no discount covers

Interest on an ordinary loan has no GST. Entry 27 of the GST exemption Notification 12/2017-Central Tax (Rate) exempts "extending deposits, loans or advances in so far as the consideration is represented by way of interest", with one carve-out in brackets: "other than interest involved in credit card services". So credit card interest carries GST at 18%, and a credit card EMI is still credit card interest. The seller's discount covers the interest. Nobody covers the GST on it. The bank bills it to you, on your statement, every month, next to the EMI.

On Jay's phone that is ₹645 over nine months (GST at 18%, the rate as of October 2026). Small, but it scales with the bank's rate and the tenure:

Reducing-balance interest in every row, GST at 18% on the interest component only. A longer "no cost" tenure is not free either: the seller discounts more, and you pay GST on more.

One useful distinction. The GST carve-out is only for credit card interest. An EMI on a debit card, or a consumer-durable loan from an NBFC on the shop floor, is a plain loan, so the interest itself is exempt. The processing fee on it is a service charge, and that does carry 18% GST.

What GST is and how it shows on a bill is explained in GST kya hai.

Credit card EMI conversion charges

The second cost is the processing fee, and it varies with the card and the route you took:

• EMI at the merchant (checkout on Amazon, Flipkart, a brand store): HDFC Bank's card terms list an EasyEMI processing fee of up to ₹299 for EMIs taken at a merchant, and for SmartEMI (converting a transaction after the purchase) ₹249 plus GST, a figure that changed from 1 October 2026 (HDFC Bank credit card MITC, updated 9 October 2026).
• Converting an old transaction into EMI yourself: SBI Card's Flexipay terms (June 2026) charge 1% of the booking amount or ₹2,000, whichever is less, and the interest rate ranges from 10% to 25% a year depending on your bureau score. On ₹60,000 that fee is ₹600 plus GST.
• Marketplace fee: Flipkart says it charges no processing fee itself, but the bank may, and the bank's fee is not refunded even if you return the phone.

For Jay, take ₹249 plus 18% GST, which is ₹294, billed in the first statement. Pre-closure, if he wants to pay it all off after a bonus, is 3% of the outstanding principal at both HDFC Bank and SBI Card. On ₹30,000 outstanding that is ₹900 plus GST, more than all the GST he was trying to avoid. On a no-cost EMI, let it run.

The discount cash buyers got, which you did not

This is the cost nobody puts on the product page. Festive sales run bank offers on top of the price: "10% instant discount with SBI debit card", "₹1,500 off with HDFC credit card". Read the terms of any such offer and you will find a line like the one in SBI's Amazon Prime Day offer of July 2026 (SBI debit card offer FAQ): "the discount under this Offer is not applicable on Credit Card EMI, Downpayment EMI and Debit Card EMI", and "Offer not valid for No Cost EMI". In that sale the mobile-phone discount was 10% up to ₹750, with a bonus ₹750 on a single transaction of ₹59,990 or more. A ₹60,000 phone paid in full would have got ₹1,500 off.

So the honest comparison for Jay is not "₹60,000 cash versus ₹60,000 in EMIs". It is this:

Bank rate 15% reducing, processing fee ₹249 + GST, instant discount ₹1,500 as in the SBI offer above. The no-cost EMI is far better than a regular EMI. It is ₹2,439 worse than paying in full. And a last trap: in a physical shop, ask what the cash price is before you ask about EMI. If the counter quotes ₹57,500 for cash and ₹60,000 "on no cost EMI", the seller has simply added the interest to your price.

The effective APR of a "0%" EMI

APR, the annual percentage rate, is the one number that folds every charge into a yearly rate, and it is what RBI's Key Facts Statement circular of 15 April 2024 makes lenders print for every retail term loan sanctioned from 1 October 2024. The circular defines APR as "the annual cost of credit to the borrower which includes interest rate and all other charges". The catch for this post: "credit card receivables are exempted", so a credit card EMI does not come with a KFS. A debit card EMI or a shop-floor consumer loan does.

So let's compute the APR ourselves. Treat the cheapest cash price as the loan amount, and everything you actually pay (nine EMIs, the monthly GST, the fee in month one) as the repayments. Then solve for the rate, the same way the flat vs reducing post converts a flat rate into a true rate:

₹60,000 phone, 9 EMIs of ₹6,667, bank rate 15%, GST billed monthly, fee in month 1. The spread is the whole point. With no fee and no lost discount a no-cost EMI is nearly free, under 3% a year. The same EMI on a phone that cash buyers get ₹3,000 cheaper is a 16% loan, about what a personal loan costs. The label is identical in both cases. Only the small print and the cash price tell them apart.

EMI on debit card: who gets it and how it works

You do not need a credit card for this any more. SBI describes it on its site as an "EMI facility to pre-approved customers, for purchasing consumer durables from merchant stores by swiping their debit cards and online from Flipkart & Amazon portals", with more than 100 merchant tie-ups, 42 of them offering zero-cost EMI (SBI, salary package page). Most large private banks run the same product under their own names.

How it is different from a card EMI:

• It is a pre-approved loan, not your bank balance. The bank looks at your account history and sets an EMI limit in advance. SBI's 2022-23 Directors' Report says the product goes to pre-approved customers "based on their account behaviour and other parameters", with the maximum loan raised to ₹2 lakh and tenures of 3 to 36 months from December 2022. You can check whether you are on the list by sending DCEMI to 567676 from your registered mobile number. If the reply says your limit is zero, the EMI option simply will not appear for your card at checkout.
• The money never leaves your savings account at purchase. The bank pays the merchant from a small loan, and a standing instruction pulls the EMI from your account each month. If the account is short on the due date, that is a loan default, reported to the credit bureau like any other.
• The interest is GST-free, the fee is not. It is a loan, not a credit card service, so the interest the seller discounts carries no GST. A processing fee still carries 18% GST. The "no cost" part works exactly as with a credit card.
• It comes with a KFS. A debit card EMI is a retail term loan, so from October 2024 the bank has to give you a Key Facts Statement with the APR. It is the one place where fee and interest sit together in one number.

What it does to your credit limit and CIBIL score

A card EMI sits on your card as a loan. SBI Card's Flexipay terms say it exactly: on approval "the SBI Credit Cardholder's Credit Limit shall be blocked up to Flexipay Principal Amount + Processing Fee + GST", and the limit "gets adjusted as and when the installment payments are made". Other issuers work the same way. On a ₹1 lakh limit, Jay's phone blocks ₹56,416 plus fee and GST on day one, roughly 57% of the limit, and the room comes back only ₹6,000-odd a month.

Three things follow from that:

• Utilisation. The blocked amount is outstanding on the card, so your credit utilisation jumps the day you tap "No Cost EMI" and stays high for the tenure. Two or three such EMIs can keep a ₹1 lakh card at 80% utilisation for most of a year, and high utilisation is one of the things bureaus mark down.
• A new line in the minimum due. Each EMI is part of the minimum amount due. Pay only the minimum on the rest of the bill and the leftover runs at the card's normal rate, 3.75% a month or 45% a year on most HDFC Bank cards per the same MITC, while you feel good about the "free" EMI.
• Loan eligibility. Banks count card EMIs as fixed obligations when they size a home or car loan. ₹6,667 a month of phone EMI cuts the home loan you can get by about ₹7.7 lakh (at 8.5% over 20 years) until it is closed. Check it on the home loan eligibility calculator if a big loan is coming up.

None of this hurts if you pay every EMI on the due date. A loan paid on time is a plus on the report. The damage is in the months you are stretched.

When no cost EMI is fine, and when it is a trap

It is a good deal when all five of these are true:

1. The price for no-cost EMI is the same as the price for full payment, and you have checked the bank-offer terms to see what a cash buyer would get.
2. The bank's processing fee is zero or close to it, and you know the number before you tap.
3. You would have bought the same thing at the same price this month anyway. The EMI only changes when you pay, not what you buy.
4. The money you are not paying now stays somewhere useful. ₹56,416 left in an FD at 6.5% for 9 months earns about ₹2,973, which more than covers the ₹645 GST. In a savings account at 3% it earns about ₹1,360, still ahead. Spent on something else, it earns nothing.
5. The EMI fits inside your month with room to spare, and you have no home or car loan application coming up.

It is a trap when the EMI is what made the purchase possible. ₹6,667 "a month" is how a ₹60,000 phone gets bought on a ₹45,000 salary, and how a ₹40,000 TV follows it in the next sale. A no-cost EMI makes the price feel one-ninth of what it is, and that is the real product being sold. The GST and the fee are small. The phone you would not have bought at ₹60,000 is the expensive part.

Two more warning signs. A "no cost EMI" offered only on 12 or 18 months, at a higher price, is the seller spreading the interest into the price. And a shop-floor loan quoted at a flat rate ("just 8% flat") is not no-cost at all: 8% flat for 9 months is about 14.2% reducing, as the flat vs reducing post explains.

The two-minute check before you tap

At the checkout, before choosing the EMI option, do this:

1. Note the final price for full payment, with every bank and coupon discount applied. That is your true cash price.
2. Open the EMI breakdown. Under the 2022 RBI direction the card issuer has to show principal, interest and the upfront discount. Write down the interest figure, which is also the number the seller is paying.
3. Add 18% of that interest, plus the processing fee with GST. On Jay's phone: ₹645 + ₹294 = ₹939.
4. Add the discount you are giving up. The gap between step 1 and the no-cost EMI price.
5. Put the total extra into the EMI calculator as if it were interest on the cash price for the tenure. Under about 4%, go ahead. Above 10%, you are taking a personal loan with a friendlier name, and the personal loan EMI calculator will show a proper loan may cost the same without the credit-limit side effects.

Jay's answer, had he done this, was about 10%. He would probably still have bought the phone. But he would have known what it cost, and that is the whole difference between a no-cost EMI and a no-questions EMI.
