Zero Cost EMI Calculator
Under a no-cost EMI offer the instalments add up to the product price, so there is no interest line on your statement. This calculator shows those instalments and then adds the two things that usually do cost money: the processing fee and any discount you give up by not paying upfront.

A ₹60,000 purchase on no-cost EMI costs ₹10,000 a month over 6 months, and its effective cost is ₹60,199, ₹199 more than the sticker price.
Most banks charge a conversion fee even on no-cost EMI.
If the cash price would have been lower, that gap is a real cost.

How a ₹50,000 Phone on 6-Month "No Cost EMI" Actually Costs ₹52,400
No-cost EMI schemes sound completely free, but banks and merchants recoup the interest through three hidden channels: forgone cash discounts, upfront processing fees, and mandatory 18% GST on interest.
| Cost Component | Advertised Amount | True Consumer Outflow | Why This Costs You Money |
|---|---|---|---|
| 1. Product Sticker Price | ₹50,000 | ₹50,000 | The retail invoice price of the smartphone. |
| 2. Forgone Upfront Discount | ₹0 (Hidden) | +₹1,500 | Paying via UPI, net banking, or full card payment qualified for an instant ₹1,500 merchant discount that is forfeited on EMI. |
| 3. Bank Processing Fee (+18% GST) | ₹0 (Ignored) | +₹235 | Most banks charge a non-refundable one-time fee of ₹199 plus 18% GST (₹35.82) to convert transactions into EMIs. |
| 4. 18% GST on Bank Interest | ₹0 (Not shown) | +₹300 | The merchant discounts ₹1,667 upfront, but the bank levies 18% GST on the monthly interest billed on your credit card statement. |
| 5. Fee Rounding & Surcharge Gap | ₹0 | +₹365 | Slight disparity between merchant subvention and bank interest compounding schedules. |
| Total Effective Cost | ₹50,000 | ₹52,400 | You pay ₹2,400 extra (Effective 16.5% p.a. borrowing cost) |
§ What Does the RBI Say About "Zero Cost" EMI?
In circular DBOD.No.BP.BC.37/21.04.048/2013-14, the Reserve Bank of India strictly banned banks from offering genuine 0% interest loan products, noting that "the concept of zero percent interest is non-existent." To circumvent this, retailers use interest subvention: the merchant provides an upfront discount equal to the interest, and the bank bills standard interest (usually 14% to 16% p.a.) on your statement. Because this interest is billed on a credit card, the government mandates 18% GST on the interest component.

- What it is:
- A calculator for what a no-cost EMI offer actually costs.
- What it calculates:
- The instalments, and the effective cost once the processing fee and any forgone cash discount are counted.
Key Assumptions
- Instalments carry no interest; the remainder lands on the final instalment.
- Processing fees and GST on them are charged separately.
- A discount you would have received paying upfront is treated as a real cost.
How does the Zero Cost EMI Calculator work?
Instalments are simply the financed amount divided by the number of months, which is the EMI formula at 0%.
No-cost EMI is typically funded by the merchant discounting the product, or by the interest being shown upfront and then reversed as a cashback. Either way, the cash price you could have negotiated is the cost you are trading away.
Banks commonly charge a one-time processing fee on EMI conversions, and GST applies to that fee. Add it in the field below to see the effective cost.
Zero Cost EMI Calculator formula
EMI = financed amount / n; Effective cost = price + processing fee + forgone discount
- financed amount
- = price minus down payment
- n
- = number of monthly instalments
- forgone discount
- = the extra discount you would have got paying upfront
Not every no-cost EMI offer is genuinely free. Compare the EMI price against the best cash price before deciding.
