Credit card EMI calculator with GST, fees and no-cost EMI
Converting a card purchase into EMIs looks simple — a phone, a laptop or a flight split into 3, 6, 9 or 12 monthly payments — but the bill carries more than the EMI. This credit card EMI calculator shows the monthly EMI and adds what the offer page often leaves out: 18% GST on every month’s interest, the one-time processing fee and the GST on it, and the true yearly cost of the conversion.
It also decodes no-cost EMI offers, where a discount cancels the interest but the GST on that interest is still billed, and checks whether closing the EMI early saves money after the foreclosure charge. Everything runs in your browser; rates and fees come from your card issuer’s offer and are entered by you. The results are estimates, not financial advice.
How to use the Credit Card EMI Calculator
- Enter the purchase amount to convert.
- Type the interest rate from the EMI offer, as % a year or % a month (cards often quote around 1–2% a month).
- Pick the tenure in months and the processing fee as a % or a rupee amount; GST is 18% by default.
- Tick No-cost EMI if the offer has an upfront discount equal to the interest.
- Read the EMI, the GST and the total extra cost, then try closing early in the foreclosure box.
- Copy the result or download the month-by-month schedule as CSV.

Outstanding principal, the charge with GST, and the interest you would save.
How credit card EMI and GST are calculated
The EMI uses the reducing-balance formula: EMI = P × r × (1 + r)n ÷ ((1 + r)n − 1), where P is the amount converted, r the monthly rate (annual rate ÷ 12 ÷ 100) and n the number of months. Each month the interest is the outstanding balance × r, and GST at 18% is charged on that interest — not on the principal. The processing fee is charged once, with 18% GST on it.
Example: ₹60,000 at 16% a year for 12 months gives an EMI of ₹5,443.85. Interest over the year is ₹5,326.22, and GST on it adds ₹958.72 — ₹144 in the first month alone, on ₹800 of interest. A 1% processing fee is ₹600 + ₹108 GST. The conversion costs ₹6,993 in total, an effective rate of about 21% a year rather than 16%.
Why card EMI interest carries GST
Interest on ordinary loans is exempt from GST, but the exemption (Sl. 27 of Notification 12/2017-Central Tax (Rate)) leaves out interest involved in credit card services, so the card issuer charges GST on it as a financial service at 18% (9% CGST + 9% SGST, heading 9971). The same rate applies to the processing fee, foreclosure charges and late fees. Rates checked on 24 October 2026; the GST field is editable if they change.
No-cost EMI: what you really pay
- A no-cost EMI splits the price evenly: ₹60,000 over 12 months is ₹5,000 a month.
- Behind it, the merchant or bank gives an upfront discount equal to the interest — ₹4,891.96 at 16% — and the card converts the reduced amount at the normal rate.
- GST on that interest (₹880.55 here) and the processing fee are still billed, so “no-cost” usually costs something. RBI’s card rules (2022 directions) require the principal, interest and discount to be shown before you convert.
- If you were offered a cash discount for paying in full, compare it with the no-cost EMI: the discount you give up is a cost too.
Closing a card EMI early
Paying off the outstanding principal stops future interest and its GST, but many issuers charge a foreclosure fee of around 2–3% of the outstanding plus GST, and some cancel the no-cost discount. The foreclosure box shows the trade-off; check your card’s terms for the actual charge. To clear revolving card debt rather than an EMI, use the credit card payoff calculator; to compare with a personal loan, try the personal loan calculator.
Credit Card EMI Calculator FAQ
How is credit card EMI calculated?
With the reducing-balance EMI formula on the amount converted, at the monthly rate and number of months of the offer. GST at 18% is then added on each month’s interest, and the processing fee plus GST is billed once.
Is GST charged on credit card EMI?
Yes — on the interest part of each EMI and on the processing and foreclosure fees, at 18%. It is not charged on the principal.
Is no-cost EMI really free?
Not quite. The interest is offset by a discount, but GST on that interest and any processing fee are still payable, and you may lose a cash discount.
What is the EMI on ₹60,000 for 12 months at 16%?
About ₹5,443.85 a month, plus GST on that month’s interest — ₹144 in the first month — and a one-time fee if your card charges one.
Can I close a credit card EMI early?
Usually yes, by paying the outstanding principal; issuers may add a foreclosure charge with GST. Enter it to see if closing early saves money.
Is this financial advice?
No. It is an estimate based on the rate, fee and GST you enter. Your card statement and the issuer’s Key Fact Statement are final.
