Reward Maths and Choosing a Card
Credit card EMI and 'no-cost EMI' in India: interest, GST, processing fees and foreclosure
How converting a credit card purchase or balance into EMIs works in India, what 'no-cost EMI' really means, GST on EMI interest, processing and foreclosure fees, and rupee examples.
A credit card EMI turns a purchase or part of your balance into fixed monthly instalments at an interest rate set by the issuer, usually lower than revolving card interest, often with a processing fee and always with 18% GST on the interest and fees. A "no-cost EMI" is normally an EMI where the merchant or brand gives an upfront discount equal to the interest, so the instalments add up to the product's price — but GST on the interest and any processing fee are still yours to pay. The RBI's card directions say an EMI with an interest component must not be camouflaged as zero-interest or no-cost EMI, so the interest should be visible in the terms. EMIs also block part of your credit limit and may not earn rewards. Figures here are illustrative.
This guide belongs to the guide to choosing a cashback or reward card. It is general information, not financial advice.
Types of card EMI
| Type | How it works | Watch out for |
|---|---|---|
| Purchase EMI at checkout | Choose EMI on the payment page or POS terminal | Interest, processing fee, GST; rewards may be reversed |
| Convert a purchase after posting | Use the issuer's app within a time window | Minimum amount, fee |
| Balance conversion | Convert part of the outstanding balance | Often higher rate than purchase EMI |
| Loan on card | Pre-approved loan within or above the card limit | Rate and fee; check it is not a cash advance |
| "No-cost" EMI | Discount offsets interest | GST on interest; processing fee; lost discounts |
Worked example: a "no-cost" EMI (illustrative)
Phone price ₹30,000, 6-month no-cost EMI, issuer interest 14% a year, processing fee ₹199.
- Total interest over 6 months on the financed amount ≈ ₹1,190 (the interest on the discounted amount).
- The merchant gives an upfront discount of ≈ ₹1,190, so the financed principal is ≈ ₹28,810.
- Instalments add up to ≈ ₹30,000 — "no cost".
- But GST on interest: ₹1,190 × 18% ≈ ₹214, billed over the six months.
- Processing fee ₹199 + 18% GST = ₹234.82.
Extra cost ≈ ₹449, about 1.5% of the price. Also check: if you had paid in full, would you have got a bigger instant discount or cashback that the EMI route does not offer? That forgone discount is part of the cost.
Worked example: ordinary EMI vs revolving (illustrative)
₹60,000 laptop. Option A: 6-month EMI at 15% with a 1% fee. Option B: pay ₹10,000 a month and revolve the rest at 3.5% a month.
| EMI at 15% | Revolving at 3.5% a month | |
|---|---|---|
| Monthly payment | about ₹10,442 | ₹10,000 then the remainder |
| Interest | about ₹2,652 | roughly ₹6,400–8,500, depending on transaction dates |
| GST on interest | about ₹477 | roughly ₹1,150–1,550 |
| Processing fee with GST | ₹708 | ₹0 |
| Interest-free period on other spends | Kept, if you pay the rest in full | Lost while revolving |
The EMI is cheaper here, and keeps your other spending interest-free if you pay the rest of each bill in full. Use the card debt payoff calculator with your rate and term.
Effects you may not expect
- Credit limit. The whole EMI principal is blocked from your limit when you convert and released as you repay.
- Rewards. Many cards do not give rewards on EMI conversions, or reverse rewards on the original purchase. Waiver and milestone spend may exclude EMIs.
- Minimum amount due. Each month's EMI is included in full in the MAD; see the minimum amount due.
- Foreclosure. Closing the EMI early may cost a foreclosure fee plus GST; interest for the remaining months is usually not charged, but any "no-cost" discount may be clawed back.
- Returns. If you return the product, ask the issuer how the EMI is cancelled and whether fees and interest already billed are refunded.
Checklist before choosing EMI
- What is the interest rate and how much interest in rupees?
- Is there a processing fee? What is it with GST?
- Is "no-cost" achieved by a discount? Is there a bigger discount for full payment?
- Will the purchase still earn rewards?
- What is the foreclosure fee?
- Can you afford the instalment and still pay the rest of each bill in full?
When an EMI makes sense
- You need a large purchase and the EMI cost is lower than the alternatives.
- You have stopped revolving and want a fixed plan to clear an existing balance.
- The no-cost discount is real, and the GST and fee are smaller than the value of keeping cash in hand.
It does not make sense to use EMIs as a way to keep spending more than your income.
Frequently asked questions
Is "no-cost EMI" banned?
No. What the RBI directions prohibit is disguising an EMI with interest as zero-interest. The interest and the discount should be shown.
Why does my statement show interest on a no-cost EMI?
Because the issuer is charging interest and the merchant gave a discount to offset it. The GST on that interest is the visible extra cost.
Does an EMI affect my credit score?
It is part of your card balance and utilisation. Paying instalments on time helps your record.
Can I convert a cash withdrawal to EMI?
Usually not. Check your issuer's terms.
