What does a "no-cost EMI" really cost?
Interest is still charged and then covered by a discount, but GST, fees and a lost cash discount can remain.
How we calculate this
EMI = price ÷ months Hidden interest = price − present value of the EMIs at the lender's rate (covered by the shop's discount) Card EMI: + 18% GST on that interest (loan interest is otherwise GST-free) Fee: + 18% GST
Card issuers and lenders calculate slightly differently. Check your statement or KFS.
Ask before you choose
- What's the full-payment price after every discount?
- What's the processing fee, and is GST extra?
- For a loan: can I see the KFS and APR? Any down payment or advance EMI?
- What happens if I close early or miss a payment?

How to read your no-cost EMI result
A “no-cost EMI” splits a price into equal monthly payments that add up to the label price. This tool works out the GST and fees you pay on top, and any cash discount you give up by not paying in full.
What the numbers mean
EMI is your monthly payment: the price divided by the number of months.
“Extra you pay” is the money you pay above the price. It has two parts. On a credit card, 18% GST is charged on the interest inside each EMI. The processing fee also carries 18% GST. On a consumer-durable loan (a loan from a finance company for goods like phones or TVs), the interest has no GST, so only the fee and its GST count.
“Total on EMI” is the price plus that extra.
The table explains where the extra comes from. “Hidden interest” is the interest the lender still charges. The shop or brand gives you a discount of the same size, so you don’t see it in the EMI. You don’t pay it directly, but on a card the GST is worked out on it.
The status at the top compares the total with the best price you could pay in full today. If paying now is cheaper, it says by how much. If not, it shows the extra as a share of the price.
Worked example
Fictional example, using the tool’s default inputs. A ₹30,000 phone on a 6-month card EMI. The lender’s rate is 15% a year. The processing fee is ₹199 before GST. The shop sells the same phone for ₹28,500 if you pay in full today.
| Line | Amount |
|---|---|
| 6 EMIs of ₹5,000 | ₹30,000 |
| Hidden interest (covered by the discount) | ₹1,270 |
| GST on that interest (18%) | + ₹229 |
| Processing fee incl. GST | + ₹235 |
| Total on EMI | ₹30,463 |
| Best pay-now price | ₹28,500 |
The extra is ₹463, about 1.5% of the price. But the pay-now discount is bigger, so the status reads “Paying in full is ₹1,963 cheaper”.
Switch to “Consumer-durable loan” with the same numbers, and the GST on interest drops out. The extra becomes ₹235 and the total ₹30,235. Paying in full is still ₹1,735 cheaper.
What this tool doesn’t do
It doesn’t include late fees, penal charges, or the cost of closing the EMI early. Missing an EMI also shows up on your credit report.
It doesn’t know about a down payment or an advance EMI (the first EMI taken at the start). For a loan, look for these in the KFS (Key Facts Statement, the one-page summary of a loan’s costs). Card EMIs have no loan KFS. The card company must still show you the principal, interest and discount before it turns a purchase into EMIs.
It doesn’t check whether the EMI fits your budget. For that, use Can I afford it?. The amounts you enter stay on your device.
Common questions
Is a no-cost EMI really free? Rarely. The interest is covered by a discount, but you may still pay GST on that interest (on cards), a processing fee with GST, and you may lose a cash discount. Compare the total with the best pay-now price.
Why is there GST on interest for card EMIs but not loans? Interest on ordinary loans is exempt from GST. Credit card interest is not exempt, so 18% GST applies to the interest part of each card EMI.
Where do I find the lender’s rate? Ask the card company or lender before you agree, because our result depends on it. For a loan, the KFS shows the rate and the APR (the yearly cost including fees). For a card, look at the interest the card company shows before it converts the purchase, and on your statement.
When does a no-cost EMI make sense? When the shop gives no extra discount for paying in full, and the EMI fits even your weak month. Then you pay only the fee and any GST.
