Festive sales are designed to remove friction. The price is lower, the banner says “No-Cost EMI”, the checkout offers “Pay in 3” or “Pay next month”, and suddenly a ₹30,000 phone costs “just ₹5,000 a month”. None of these products is a scam. But the word “no-cost” does a lot of work, and the real number only appears when you do the maths.
This is day 3 of our Diwali 2026 series. On day 1 we set a festive budget; on day 2 we covered how to use a Diwali bonus. Today: the real cost of festive credit.
How “no-cost EMI” actually works
A bank or NBFC lends you the price of the product and charges interest, as on any loan. To make it “no-cost”, the seller or brand gives you a discount equal to that interest. You pay the original price in instalments; the lender still earns its interest, funded by the discount.
So far, genuinely close to no cost. Now add what sits around the loan.
The worked maths: a ₹30,000 phone
| Item | Amount |
|---|---|
| Product price | ₹30,000 |
| Interest (illustrative 16% a year, 6 months), offset by discount | ≈ ₹1,350, net ₹0 |
| GST at 18% on the interest component | ≈ ₹243 |
| Processing fee (illustrative ₹199 plus 18% GST) | ≈ ₹235 |
| Total you pay on “no-cost EMI” | ≈ ₹30,478 |
| Alternative: pay in full with an instant ₹1,500 card discount (illustrative) | ₹28,500 |
| Real cost of choosing EMI in this example | ≈ ₹1,978 |
Illustrative figures. Interest rates, fees and how GST is applied vary by lender and card; check the offer terms and the loan’s Key Fact Statement or card terms for your actual cost. Many sales let you take either an instant discount or no-cost EMI, not both.
Extra paid for the same ₹30,000 phone, compared with the best upfront price
Illustrative. Best upfront price assumed ₹28,500 after an instant card discount. The late-payment bar adds an illustrative ₹500 late fee plus 18% GST; a missed EMI can also be reported to credit bureaus.
About ₹2,000 on a ₹30,000 phone is not a disaster. The point is that “no-cost” is a label, not a promise, and the real gap is mostly the upfront discount you skip.
Four costs that don’t show on the banner
Blocked card limit
On a credit card, the full purchase amount is usually blocked from your limit and released as you pay EMIs. Your utilisation jumps, which can weigh on your credit score and leave less room for emergencies.
Lost upfront discount
The best price is often reserved for paying in full. Compare the EMI total with the lowest upfront price, not the list price.
Fees and GST
Processing fees and GST on the interest are small individually but turn “no-cost” into “low-cost”. Pre-closing early can also attract charges.
Stacking
Phone, TV, laptop, fridge: four “small” EMIs started in one sale can add up to a large monthly commitment for a year.
Buy Now Pay Later: what it really is
BNPL lets you split a purchase into a few instalments or pay it all later, often in 15 to 30 days, with nothing extra if you pay on time. It is credit from a regulated lender, even when the button sits inside a shopping app.
- It shows on your credit report. Signing up can involve a credit check, and repayments are reported. Pay late and your score can fall like with any other loan.
- Late fees add up. A missed due date usually means a late fee, sometimes plus interest. Read the Key Fact Statement for the exact amounts.
- It is easy to have several. One BNPL line per shopping app quietly becomes four due dates a month.
- It feels like spending, not borrowing. That is the design, and it is why it’s easy to overuse.
If you already have several BNPL lines and app loans and find yourself paying one with another, that is a rollover cycle. Read about SmartSwitch or our guide to getting out of a debt trap.
Your six-question checkout checklist
Was it on my list before the sale?
If not, the EMI is helping you buy something you didn’t plan for. Wait 24 hours.
What is the lowest upfront price?
Compare the EMI total with the best pay-now price, including instant discounts.
What are the fees and is GST charged on interest?
Read the offer terms or the KFS, not the banner.
How much card limit will it block?
Keep enough free limit for emergencies and to avoid high utilisation.
What do all my EMIs add up to?
Add this EMI to every existing one, including other no-cost and BNPL plans. If the total makes you nervous, it is too much.
What happens if I’m late once?
Know the late fee and set up auto-debit from your salary account.
Use EMI to spread a purchase you planned, never to justify one you didn’t.
Where a personal loan fits, and where it doesn’t
For a phone or a TV, the best answer is usually saving for it or a genuine no-cost EMI paid on time. A personal loan is better suited to larger, planned needs such as home repairs or a family event, or to replacing several scattered EMIs and app loans with one predictable instalment. An Omozing personal loan starts from 11% a year, with the exact rate, fees and APR in the Key Fact Statement before you sign. We consider salaried applicants with a credit score from 600. We do not run festive or “Diwali” offers.

Frequently asked questions
Is no-cost EMI really free?
The interest is usually offset by an equal discount, so the loan itself costs little. But processing fees, GST on the interest component and any upfront discount you give up can make it cost more than paying in full.
Does no-cost EMI affect my credit score?
It is a loan, so it is reported to credit bureaus. On a credit card it also blocks part of your limit, raising utilisation. Paying every EMI on time is what matters most.
Is Buy Now Pay Later a loan?
Yes. BNPL is credit from a regulated lender. It can appear on your credit report, and late payments can attract fees and hurt your score.
Is GST charged on no-cost EMI?
Lenders commonly charge GST on the interest component and on processing fees. Check the offer terms and your card or loan statement for the exact amounts.
Can I close a no-cost EMI early?
Usually yes, but some lenders charge a foreclosure fee and you may lose part of the benefit. Check the terms before you choose the EMI option.
Is it better to use a personal loan for festive shopping?
For everyday festive shopping, it’s better not to borrow at all. A personal loan suits larger, planned needs, or replacing several costly short-term debts with one EMI.
