Festive Car Loans and “Zero-Cost EMI”: The Real Interest Rate Behind the Offer, With Worked Examples
A ₹60,000 phone on a 6-month No Cost EMI still costs ₹598 to ₹898 more than its price, in GST on the interest and the bank's processing fee. Give up a ₹3,000 discount for paying in full and it becomes a loan at 23% a year. A car loan quoted at 5.5% flat is really 10%. Worked examples, the GST on each charge, late fees, and the RBI rules that protect you.
"No Cost EMI" and "0% car finance" are the two biggest words of the festive season. Some of these offers really are cheap. Many are not free at all: the cost sits in GST on interest you never see, a processing fee, a discount you lose for not paying in full, or a "flat" rate that is close to double in real terms. A ₹60,000 phone on a 6-month No Cost EMI still costs ₹598 to ₹898 more than its price. Give up a ₹3,000 discount for paying in full and the same EMI is a loan at 23% a year. This guide works through each offer with real figures, shows the GST on every charge, and sets out the RBI rules that protect you.
Written on 18 October 2026. How a No Cost EMI works and each bank's processing fee are from Amazon India's own pages; the card example rate is the one in SBI Card's published terms; car loan rates and fees are from SBI's website; the rules are RBI's circulars and directions; the GST treatment is from the GST Council's rate schedule and its 55th and 56th meetings. Offers and fees change often: check yours on the day you buy.
₹898 — what a ₹60,000, 6-month No Cost EMI really costs on a card with a ₹299 fee · 5.1% — the yearly rate that works out to · 23.2% — the rate if you give up ₹3,000 off for paying in full · 10.0% — the real rate of a car loan quoted at 5.5% flat · 18% — GST on credit card EMI interest and on every fee · Nil — GST on car loan interest and on penal charges for a late EMI
How a No Cost EMI works
When you split a purchase into EMIs on a credit or debit card, the bank charges interest. On a No Cost EMI, as Amazon explains it, "this interest charge has been provided to you as an upfront discount": the seller knocks the bank's interest off the price, so your EMIs add up to exactly the price you saw.
Take a ₹60,000 phone over 6 months, on a bank EMI rate of 18% a year, the rate SBI Card uses in the EMI example in its own terms:
That is the interest the bank will charge over 6 months. The bank lends you ₹56,972, not ₹60,000.
₹56,972 plus ₹3,028 of interest is exactly ₹60,000. So far, it really is no cost.
GST of 18% on that ₹3,028 of interest, and the bank's processing fee with GST on it. These are not covered by the seller.
Amazon says so in plain words on its No Cost EMI page: "Your bank will charge GST on the interest component of the EMI". The reason is in GST law: interest on a loan is exempt, but the exemption specifically leaves out "interest involved in credit card services". So card EMI interest is taxed at 18%; loan interest is not.
What a No Cost EMI really costs: the worked example
The same ₹60,000 phone, 6 EMIs, at the processing fees Amazon lists for two cards: SBI Card charges ₹45 plus tax on a 6-month EMI of ₹20,000 or more; HDFC Bank and ICICI Bank credit cards charge ₹299 plus GST.
| What you pay beyond ₹60,000 | SBI Card (₹45 fee) | HDFC or ICICI card (₹299 fee) |
|---|---|---|
| Interest the seller pays for you | ₹3,028 | ₹3,028 |
| GST of 18% on that interest | ₹545 | ₹545 |
| Processing fee with 18% GST | ₹53 | ₹353 |
| Total extra | ₹598 | ₹898 |
| Like a loan at | 3.4% a year | 5.1% a year |
The GST arrives month by month with each EMI, on that month's interest: about ₹154 in the first month, falling to ₹27 in the sixth. The fee comes with the first EMI. A longer plan costs more: on SBI Card's fees, the same ₹60,000 over 9 months costs about ₹849, and over 12 months about ₹1,088.
That is a cheap loan. If spreading the payment really helps you, it is a fair deal. It is just not "no cost".
When the price is higher, or the discount goes missing
The bigger cost hides elsewhere. Festive offers often give an instant discount only if you pay in full, or show a lower price elsewhere for a cash buyer. When you choose the No Cost EMI, you give that up. The discount you lose is interest, in all but name:
| Discount you give up to take the EMI | Total extra (with the ₹299 fee) | Like a loan at |
|---|---|---|
| ₹2,000 | ₹2,898 | 17.0% a year |
| ₹3,000 | ₹3,898 | 23.2% a year |
| ₹5,000 | ₹5,898 | 36.1% a year |
The same arithmetic applies when the No Cost EMI is offered only on a higher listed price: the difference from the best price you could pay in full is the interest. RBI said as much in 2013, when it told banks that discounts from a dealer or manufacturer must be passed on, that the loan should be for the price "after taking into account the discount", and that a zero-interest label must not hide the cost.
Instant discount or cashback? An instant discount comes off the price you pay today, and if it is printed on the invoice it is also left out of the value GST is charged on (section 15(3)(a) of the CGST Act). A cashback is paid later, outside the invoice, and only if you meet the offer's terms, which can include not cancelling or closing the EMI early. Compare offers on the money you actually pay, on the day you pay it.
Festive car loans: the flat-rate trap
Car dealers and some lenders quote a "flat" rate. A flat rate charges interest on the full loan for the whole tenure, even though you repay part of it every month. A bank's rate is on the reducing balance: you pay interest only on what you still owe. SBI, for instance, works out car loan interest on the daily reducing balance.
The same ₹8 lakh car loan over 5 years, three ways:
| Quote | EMI | Total interest | Real yearly rate |
|---|---|---|---|
| SBI, 9% reducing, ₹1,000 fee + GST | ₹16,607 | ₹1,96,401 | 9.06% |
| 5.5% flat | ₹17,000 | ₹2,20,000 | 10.0% |
| 5.5% flat, with a 1% fee + GST (₹9,440) | ₹17,000 | ₹2,20,000 | 10.5% |
| 6% flat | ₹17,333 | ₹2,40,000 | 10.85% |
| 7% flat | ₹18,000 | ₹2,80,000 | 12.5% |
An easy rule: the real rate is a little under double the flat rate. The "lower" 5.5% costs ₹393 more a month than SBI's 9%. The flat-rate EMI calculator turns any flat quote into its real rate.
What SBI publishes today for a new car: rates from 8.55% to 9.50% depending on your credit score, fixed for the whole loan; funding of up to 100% of the on-road price; a processing fee of ₹500, ₹1,000 or ₹1,500 plus GST for salaried borrowers, by loan size; no prepayment charges, and no foreclosure charges after 2 years.
The "0% car finance" offer: when it really is cheaper
A dealer's zero-interest scheme is usually paid for by the carmaker. The catch is that it often replaces the cash discount you would otherwise get. Whether it is a good deal depends on how big that discount is.
Say a car costs ₹10 lakh and you put down ₹4 lakh. The dealer offers two ways:
Borrow ₹6 lakh at 0% for 36 months: EMI ₹16,667. No cash discount. Processing fee ₹10,000 + GST. Total paid on the loan: ₹6,11,800.
Take the ₹50,000 discount and borrow ₹5.5 lakh from SBI at 9% for 36 months: EMI ₹17,490. Fee ₹1,000 + GST. Total paid: ₹6,30,815.
Here the 0% offer is genuinely cheaper, by ₹19,015: losing ₹50,000 to borrow at 0% works out to about 7.2% a year, below the bank's 9%. But if the cash discount were above ₹64,087, Offer B would win; at ₹75,000 the "0%" offer costs about 10.4% a year. Ask for both prices in writing, with the fees, before you choose.
GST: what is taxed and what is not
| Charge | GST | Why |
|---|---|---|
| Interest on a car, home or personal loan | Nil | Interest on loans is exempt |
| Interest on a credit card EMI, including a No Cost EMI | 18% | The exemption leaves out interest in credit card services |
| Processing fee on a loan or an EMI conversion | 18% | Financial and related services |
| Card fees, late fees and finance charges | 18% | SBI Card's terms, for example, add GST at 18% to its fees and finance charges |
| Penal charges for a late car or home loan EMI | Nil | The GST Council clarified in December 2024 that no GST is payable on penal charges banks and NBFCs collect for non-compliance with loan terms |
| The car itself | 18% or 40% | From 22 September 2025: 18% on small cars (petrol, LPG or CNG up to 1,200cc, diesel up to 1,500cc, and no longer than 4 metres); 40% on bigger petrol and diesel cars, hybrids included |
The loan does not change the GST on the car: GST is on the invoice price, whether you pay cash or borrow. For more on how the September 2025 rates changed what appliances cost, see GST on the Indian household.
Late payment: what a missed EMI costs
On a card EMI, a missed EMI is a missed card payment, and it is expensive. RBI's rules say a card issuer can charge a late fee only when the account is more than three days past due, and only on the amount outstanding after the due date. SBI Card's fee is ₹750 where ₹1,000 to ₹10,000 is outstanding, rising to ₹1,300 above ₹50,000, with GST on top. Interest is charged on what is unpaid at up to 3.75% a month, 45% a year, and the interest-free period on new purchases stops while any of last month's bill is unpaid. One missed ₹10,000 EMI can cost more than the whole "no cost" saving.
On a car loan, RBI's rules since 2024 are kinder. A late EMI can carry only a "penal charge", not extra interest; no interest may be charged on that charge; it must be "reasonable", written in the loan agreement and the Key Facts Statement, and named in any reminder. And, as above, there is no GST on it.
The simplest protection for both: set up an auto-debit from your salary account for the EMI date.
The rules that protect you
- No hidden interest in a "No Cost" EMI. RBI's card directions say an EMI with an interest component "shall not be camouflaged as zero-interest/no-cost EMI". The card issuer must show you the principal, the interest and the upfront discount before you convert, and again in your card statement.
- Discounts belong to you. RBI's 2013 circular told banks to pass on dealer and manufacturer discounts, to lend on the price after the discount, and not to hide interest in a processing fee.
- The real rate is on paper. Every retail loan sanctioned from 1 October 2024, a car loan included, comes with a Key Facts Statement showing the annual percentage rate (APR). The APR must include every charge the lender levies, and even insurance or legal charges it collects for others. You get at least three working days to decide, and a fee not in the statement cannot be charged later without your consent. Card EMIs are outside this rule; the card directions above cover them.
- Late charges have limits. Loans: a disclosed penal charge, no penal interest, no interest on the charge. Cards: a late fee only after three days past due, and unpaid charges are not added in for interest.
- Prepaying. A floating-rate loan taken by an individual can be prepaid without charge. A fixed-rate car loan can carry a foreclosure charge; SBI charges none after 2 years. On a card EMI, closing early or returning the product can bring a foreclosure charge from the bank, and Amazon's EMI page notes that on instant-discount offers a bank's foreclosure charge can apply even when the EMI is cancelled within 15 days.
Check your own offer
A small calculator loads here when JavaScript is on. The tables above carry the same arithmetic, and the flat-rate EMI calculator works out the real rate behind a car loan quote.
Your bank's EMI screen shows its interest rate and processing fee before you confirm. If the seller offers a discount for paying in full, enter it in the last box: that is usually the number that decides it.
Before you sign: a checklist
- Ask the full-payment price. If it is lower, the difference is interest. Put it in the calculator above.
- Read the EMI screen. Note the bank's rate, the processing fee, and the interest and discount it shows.
- For a car, ask for the Key Facts Statement and compare the APR, never the flat rate. Get the dealer's and the bank's quotes side by side.
- Ask about foreclosure. If you might pay early or return the product, know the charge first.
- Prefer a discount on the invoice to a cashback that arrives later on conditions.
- Pay every EMI on time, by auto-debit if you can. On a card, one late month wipes out the deal.
- Check your first two card statements. The interest, the discount and the GST should match what you were shown.

Frequently Asked Questions
Is No Cost EMI really free? No. The seller covers the bank's interest, but you still pay GST of 18% on that interest and the bank's processing fee with GST. On a ₹60,000 purchase over 6 months that is ₹598 to ₹898, depending on the card.
Why is GST charged on a No Cost EMI? Interest on loans is exempt from GST, but the exemption excludes interest in credit card services. A card EMI is a credit card service, so its interest is taxed at 18%, even when the seller has paid that interest for you.
Is a No Cost EMI a good idea if the cash price is lower? Usually not. Giving up a ₹3,000 discount to spread ₹60,000 over 6 months is like borrowing at about 23% a year. If you have the money, pay in full.
How do I convert a flat interest rate to the real rate? Roughly, the real rate is a little under double the flat rate: 5.5% flat over 5 years is about 10.0% a year, 7% flat about 12.5%. The flat-rate EMI calculator on this site gives the exact figure.
Is 0% car finance better than a bank loan? It depends on the cash discount you give up. On a ₹6 lakh loan over 3 years, losing a ₹50,000 discount makes the 0% offer cost about 7.2% a year, cheaper than a 9% bank loan; above about ₹64,000 of lost discount, the bank loan is cheaper.
Is there GST on a late EMI charge? Not on a loan: the GST Council clarified that penal charges banks and NBFCs collect for non-compliance with loan terms carry no GST. Credit card late fees are different, and card issuers add GST to them.
Can I close a car loan early? A floating-rate loan to an individual can be prepaid without charge. Many car loans are fixed-rate, where a foreclosure charge may apply; SBI's new car loan has no prepayment charges and no foreclosure charges after 2 years. Your Key Facts Statement lists the charge.
Figures as at 18 October 2026. The card example uses an 18% bank rate, from SBI Card's own EMI illustration; your bank's rate may differ, and the calculator above takes yours. Real yearly rates are worked the way an APR is, from the money you receive and the money you pay, month by month. This is general information, not advice: the offer terms, your card's terms and your loan's Key Facts Statement govern your own purchase.
