Credit card EMI calculator

Converting a purchase or outstanding balance to EMI feels convenient, but the processing fee and GST are real costs on top of interest — even on cards advertising "no-cost EMI". See the full picture.

"No-cost EMI" still has a cost. At 0% interest, this calculator will still show a processing fee and GST if you've entered one — that's the real cost of a "no-cost" offer. Not every issuer charges a fee on every offer, and some merchants absorb it into the price; check your specific offer's terms.

Is this EMI actually cheap?

The monthly figure always looks small. This is what the same purchase costs three different ways — paid in full, converted to EMI, or left to revolve on the card.

What "EMI conversion" actually means

When you convert a purchase or existing balance to EMI, the issuer splits the amount into fixed monthly instalments, usually at a quoted interest rate. Two costs sit alongside that interest: a one-time processing fee (commonly 1-3% of the amount), and GST, which in India applies to financial service fees at the standard rate.

How this calculator works

Monthly EMI = standard reducing-balance EMI on the transaction amount, rate and tenure.
Interest cost = (EMI × tenure) − transaction amount.
Processing fee = transaction amount × fee%. GST = fee × 18% (if selected).
Total financing cost = interest + fee + GST. Effective cost above price = financing cost ÷ transaction amount × 100.

A worked example

A ₹50,000 purchase converted to EMI at 15% p.a. over 6 months, with a 2% processing fee plus 18% GST:

The EMI comes to about ₹8,702/month, totalling roughly ₹52,210 — about ₹2,210 in interest. Add the ₹1,000 processing fee and ₹180 GST, and the total financing cost is about ₹3,390 — roughly 6.8% above the original purchase price.

"No-cost EMI" — read the fine print

A 0% interest offer removes the interest line entirely, but if a processing fee still applies, it isn't truly free — you're paying that fee (and its GST) for the convenience of spreading payments. Set the rate to 0% above to see exactly what a "no-cost" offer on your numbers actually costs, if any fee applies.

FAQ

Common questions

Is "no-cost EMI" really free?
Often close to it on interest, but not necessarily on fees — many no-cost EMI offers still carry a processing fee, and some effectively build the discount you'd have gotten for paying upfront into the "no-cost" structure. Check the specific offer's terms, including whether a discount was foregone.
Does converting to EMI affect my credit score?
The EMI itself becomes a fixed obligation that counts toward your overall debt, similar to a loan, and paying it on time is neutral to positive for your score. It also usually stops earning further reward points on that portion, since it's no longer revolving credit.
Can I prepay or cancel a card EMI early?
Many issuers allow foreclosure of a card EMI, sometimes with a small foreclosure fee. Check your specific card's EMI terms before assuming you can exit early at no cost.
Is GST always charged on the processing fee?
GST applies to financial services fees at the standard rate in India, and processing fees on EMI conversions are typically no exception — but confirm with your specific issuer, as presentation can vary (some show fee and GST separately, others as one bundled figure).
How is this different from just paying the minimum due?
EMI conversion locks in a fixed schedule and (usually) a lower rate than the card's standard revolving rate, but adds an upfront fee. Paying only the minimum due keeps the higher revolving rate and a shrinking payment — often costing far more over time. See the minimum due calculator to compare.
