There's no such thing as a no-cost EMI

Walk into any electronics store or open any checkout page in India right now, and you’ll see the same banner: No Cost EMI. Zero percent. Zero markup. Buy now, pay later, pay nothing extra for the privilege.

Somebody is paying for that credit. It’s rarely the store, and it’s rarely the bank. Usually, it’s you — just not in a place the banner points to.

Where the zero hides the cost

“No-cost EMI” almost always means one of three things is happening quietly in the background:

The discount you didn’t take. Many “0% EMI” prices are simply the full sticker price. Pay in cash, and the same store will often knock off 3–5% without blinking. That discount is the real cost of the EMI — it’s just been renamed “no cost” instead of “here’s what you gave up.”

The processing fee, folded in. Some lenders charge a flat processing fee on the loan, then the retailer subsidizes part of your “interest” using the margin they’d otherwise have given you as a discount. The math still nets out in the seller’s favor. It has to — nobody extends you credit for free.

The money’s time value, which never shows up on a receipt. Even in the rare case where the price is genuinely identical either way, you’ve now committed a fixed sum every month for the tenure. That money couldn’t sit in your account, in a savings instrument, or go toward anything else you needed it for. That’s a real cost. It just isn’t denominated in rupees on the invoice.

What the real number looks like

None of this shows up as a percentage on the checkout page — which is exactly the point. A rate is easy to wave past. A rupee amount is not.

Take a genuinely fee-loaded “0% EMI” purchase: a phone priced at ₹21,000 on EMI, versus ₹20,000 if you’d paid cash. Spread over 6 months at 0% interest, you’d still pay ₹21,000 in total — ₹1,000 more than the cash price, despite paying no interest at all. The “0%” was true. The “no cost” wasn’t.

That’s the number worth knowing before you tap “Pay via EMI” — not the advertised rate, but the actual rupee gap between what you’ll pay across the tenure and what you’d pay today in cash.

Control your debt. Enjoy your life.

None of this is an argument against EMIs. Spreading a big purchase over a few months is often the right call — that’s what EMIs are for. The issue isn’t financing. It’s financing you can’t see clearly, dressed up in a word (“free”) that doesn’t hold up once you do the arithmetic.

Dette’s Pre-Purchase Check does that arithmetic for you — real cost versus cash price, before you commit, in plain rupees. Not to talk you out of the purchase. Just so the number in your head matches the one that’s actually true.
