How credit card EMI is calculated

When you convert a credit card purchase to EMI, the bank charges interest on the reducing outstanding balance, a one-time processing fee, and 18% GST on both the interest and the fee. The EMI itself uses the standard reducing-balance formula.

EMI Formula (Reducing Balance)
EMI = P × r × (1+r)^n / ((1+r)^n − 1)
Where P = Purchase amount, r = monthly rate (annual ÷ 1200), n = tenure in months.
True Cost (with GST)
Cost = Interest + Fee + 18% GST
GST at 18% applies to both the interest component and the processing fee, so the headline rate understates what you actually pay.

Worked example

Suppose you convert a ₹50,000 purchase into EMI at 16% p.a. for 12 months, with a 1.5% processing fee. The monthly rate r = 16 ÷ 1200 = 0.01333. Using the formula, the EMI works out to about ₹4,537/month. Over 12 months you pay ₹54,448, so the interest is roughly ₹4,448. The processing fee is 1.5% of ₹50,000 = ₹750. GST at 18% on (₹4,448 + ₹750 = ₹5,198) adds about ₹936. So the total cost is approximately ₹56,884 — meaning the convenience of EMI costs you around ₹6,884, or about 13.8% of the purchase amount.

Tips for credit card EMI

Watch the GST

Banks charge 18% GST on the interest and processing fee. A "no-cost EMI" offer often still attracts GST on the discounted interest, so the real cost is rarely truly zero.

Shorter tenure is cheaper

A 3-month EMI on ₹50,000 costs far less interest than 24 months. Pick the shortest tenure your budget can absorb to cut total interest.

Check foreclosure charges

Most issuers allow you to pre-close the EMI plan, but may levy a 2–3% foreclosure fee on the outstanding principal plus GST. Confirm before converting.

Frequently asked questions

What is the typical credit card EMI interest rate in India?

Credit card EMI conversion rates in India typically range from 13% to 18% p.a. on a reducing-balance basis, depending on the issuer, tenure and offer. Some merchant or festive offers go lower, while revolving-credit interest (if you do not convert to EMI) can be as high as 36–42% p.a.

Is GST charged on credit card EMI?

Yes. Banks charge 18% GST on the interest component of each EMI as well as on the one-time processing fee. This is over and above the EMI itself, so your effective cost is higher than the quoted interest rate suggests.

Is no-cost EMI really free?

Not entirely. In a no-cost EMI, the interest is usually given back as an upfront discount, but you still pay 18% GST on that notional interest and often a processing fee. So a no-cost EMI typically carries a small real cost of 2–4% of the purchase value.

Can I foreclose a credit card EMI early?

Most card issuers let you pre-close an active EMI plan. However, they may charge a foreclosure or pre-closure fee of around 2–3% on the outstanding principal, plus 18% GST on that fee. Check your issuer’s terms before converting.

Does credit card EMI affect my credit limit?

Yes. The full outstanding EMI amount is blocked against your available credit limit until it is paid off. As you pay each EMI, the corresponding portion of your limit is gradually released back for use.
