Key Takeaways
- No-Cost EMI is NOT interest-free; the retailer gives an upfront discount equal to the total loan interest charged by the bank.
- You MUST pay 18% GST on the monthly interest portion charged by your credit card issuing bank.
- Most banks charge a non-refundable one-time processing fee ranging from ₹99 to ₹199 plus GST.
- If you return an item bought on No-Cost EMI, bank interest already charged and processing fees are non-refundable.
How No-Cost EMI Actually Works Under RBI Rules
RBI guidelines prohibit banks from offering zero-interest loans. Therefore, e-commerce platforms and merchants structure No-Cost EMIs using a merchant discount model:
- Upfront Discount: The merchant reduces the item price upfront by an amount equal to the total interest you would owe the bank.
- Full Loan Interest: Your credit card bank charges standard EMI interest (13%–16% p.a.) on the discounted principal balance.
- Net Result: Your total EMI payments equal the original non-discounted product price, but with added 18% GST tax!
The Hidden 18% GST & Processing Fee Calculation
Here is an example buying a ₹60,000 smartphone on 6-month No-Cost EMI at 15% interest:
- Upfront Merchant Discount: ≈₹2,540 discount given upfront (Product billed at ≈₹57,460).
- Total Bank Interest: ≈₹2,540 charged over 6 monthly EMIs, equal to the merchant discount.
- Hidden 18% GST on Interest: ≈₹457 (18% of ≈₹2,540 interest).
- One-Time Processing Fee: ₹199 + ₹36 GST = ₹235.
- Real Cost: ≈₹60,692 (You pay ≈₹692 MORE than the original product price!).
How to Calculate No-Cost EMI Charges Yourself
You don't need to trust a bank's marketing — the true cost of any No-Cost EMI offer can be worked out in four steps, continuing the same ₹60,000 / 6-month / 15% example above:
- Add the ₹199-ish one-time processing fee plus its 18% GST (≈₹235 total) to Step 4's GST to get your full extra outgo above the sticker price.
- A shorter tenure lowers the interest and GST charged since less time passes on the financed principal, even though the monthly instalment is higher.
- This calculator's No-Cost EMI tab runs this exact calculation for any product price, tenure and bank interest rate.
| Step | Calculation | Result |
|---|---|---|
| 1. Monthly instalment | ₹60,000 ÷ 6 months | ₹10,000 / month |
| 2. Implied financed principal | Principal that produces this EMI at 15% reducing-balance interest | ≈ ₹57,460 |
| 3. Interest charged (= merchant discount) | Sticker price − financed principal | ≈ ₹2,540 |
| 4. GST on interest (18%) | ≈₹2,540 × 18% | ≈ ₹457 |
Frequently Asked Questions
Is No-Cost EMI really free of interest?
No. The merchant gives an upfront discount equivalent to interest, but your bank charges full EMI interest and you must pay 18% GST on that interest.
Does No-Cost EMI affect credit score?
Yes. Converting a purchase into an EMI blocks your credit card limit and lowers your credit utilization ratio until paid off.
How do I calculate the real cost of a No-Cost EMI calculator offer?
Work backward from your monthly instalment (price ÷ tenure) to find the financed principal implied by the bank's reducing-balance interest rate. The gap between that principal and the sticker price is the interest you're actually charged — then add 18% GST on that interest, plus any processing fee and its GST, to get your true all-in cost.
What are the typical No-Cost EMI charges on a purchase?
Expect two charges even on a "no cost" offer: 18% GST on the interest component (which the merchant discount otherwise hides), and a one-time processing fee of roughly ₹99–₹299 plus 18% GST on that fee. Together these typically add 1-2% to the sticker price, depending on tenure and interest rate.
