How does No-Cost EMI work in reality?

When you choose the No-Cost EMI option instead of quick payment and buy products with a credit card. At that time, the transaction goes through a specific discount and interest process. 

Let me explain this with an example: 

Let's suppose you buy a smartphone priced at ₹30,000 for a 3-month EMI; now the bank is charging interest at 15% per year. That means your interest is ₹734.66.

• Step-1: Your seller is giving you a discount of ₹735. Your card is charged ₹29,265.34.
• Step 2: The bank converts ₹29,265.34 into an EMI loan and adds the ₹734.66 interest over the 3-month period.
• Step 3: You pay 3 monthly installments of ₹10,000. It makes the total principal repayment ₹30,000.
• Step 4: The bank charges 18% GST on the ₹734.66 interest, which comes to ₹132.24.
• Step 5: The bank may also charge a one-time EMI conversion fee, usually around  ₹199 + 18% GST.

Explanation:

Annual Interest Rate (R): 15%

Monthly Interest Rate (r):

15% /12 = 1.25% = 0.0125 12

Tenure (n): 3 months

EMI = 29, 265.34 × 0.0125 × (1 + 0.0125)3 / (1+0.0125)3 - 1

EMI = 29, 265.34 × 0.0125 × (1.03797) / 1.03797-1

EMI = 29, 265.34 × 0.341704 = ₹10,000.00

Interest: 29, 265.34 x 0.0125 = 365.82

Principal Repaid: 10,000 – 365.82 = 9,634.18

Interest GST: 365.82 × 0.18 = 65.85

Remaining Loan: 29, 265.34 – 9, 634.18 = 19, 631.16

Interest: 19, 631.16 x 0.0125 = 245.39

Principal Repaid: 10,000 – 245.39 = 9,754.61

Interest GST: 245.39 × 0.18 = 44.17

Remaining Loan: 19,631.16 – 9, 754.61 = 9,876.55

Interest: 9, 876.55 x 0.0125 = 123.45 (adjusted slightly for final rounding)

Principal Repaid: 10,000 – 123.45 = 9,876.55

Interest GST: 123.45 × 0.18 = 22.22

Remaining Loan: 9,876.55 – 9,876.55 = ₹0.00

Final Total Calculations 

Sum of Interest Charged:

365.82 + 245.39 + 123.45 = ₹734.66

Sum of Interest GST: 65.85 + 44.17 + 22.22 = 132.24

Bank Processing Fee with GST:199+ (199 × 18%) = 199 + 35.82 = 234.82

Total Cost = 30,000 + 132.24 +234.82 = 30,367.06

So, even though the offer is called No-Cost EMI, your final payment can be higher than the advertised product price because banks like HDFC, ICICI, or SBI will append a one-time "EMI Conversion Fee”.

What are the hidden costs associated with No-Cost EMI?

You may think that the No-Cost EMI is  completely free, but it's not like that. There are still some additional costs. These charges can increase the amount you pay. 

• When you choose a credit card EMI, the bank charges 18% GST on the interest amount. Under Indian tax rules, normal loan interest is generally exempt from GST. But interest charged on credit card EMI conversions can attract GST as part of the taxable credit card service.
• Your banks can charge a non-refundable EMI processing fee. This is around ₹199 + 18% GST. It depends on the offer and bank.
• If you choose EMI, you may not be able to use an instant discount offered for full upfront payment. For example, a bank may offer 10% off if you pay the entire amount at once.
• If you want to close the EMI before the end of the tenure, the bank can charge a foreclosure or preclosure fee, which is around 2% to 5% of the remaining principal + 18% GST. It also depends on the card and terms.
• The full purchase amount can be blocked against your credit card limit when the EMI is created. Your available limit is then restored gradually as you pay each EMI.

That's why you should check all the charges and discounts before choosing a No-Cost EMI.

What are the eligibility criteria and documents required for No-Cost EMI?

Now, anyone can not go for No-Cost EMI. If you want to use a No-Cost EMI option, you need to meet certain criteria. These requirements are not the same for everyone. It is different for credit cards, debit cards, or NBFC financing. 

Eligibility Criteria:

• First, you should have an active credit card from a participating bank. Also, it should have enough available credit limit to cover the product price.
• You must be pre-approved by your specific bank based on your average balance, account vintage, and transaction history. Minimum cart values usually apply

• You need to be at least 21 years old, be an Indian citizen, have a regular income, and have a satisfactory credit score. 

   

Documents Required (for NBFC / Cardless setups):

• PAN Card
• Aadhaar Card for digital KYC
• Bank account details or NACH e-mandate for automatic EMI payments
• Identity and address proof for offline consumer durable financing

Existing credit card customers generally do not need to submit new documents for a credit card EMI conversion, subject to the bank's requirements.

Conclusion 

When you want to buy an expensive thing without paying full amount, No-Cost EMI is becoming a good option. You can pay the amount in instalments. But it doesn't mean that you pay zero extra amount. Here,the interest cost is adjusted through a merchant discount or interest subsidy. You still have to pay 18% GST on applicable credit card interest and processing fees. You may also lose an instant discount that was available for full upfront payment. So, before choosing No-Cost EMI, compare the final amount payable under EMI with the price you would pay if you purchased the product in full. This will help you decide whether the EMI offer is actually beneficial.
