Almost every air conditioner sold online in India now carries an EMI banner before it carries a price. Nine months, no cost, starting at a figure small enough to feel like a subscription. For a machine bought in the week the first heatwave lands, that framing works — and it is not a scam. But « no cost » is a commercial arrangement between a bank and a seller, not an absence of interest, and two or three real charges survive the arrangement. They are small. They are also entirely predictable, which means you can price them before you tap the button rather than discover them on the statement.

Why the interest exists even when you do not pay it

In September 2013 the Reserve Bank of India told banks to stop offering zero-percent schemes on consumer durables, on the grounds that the interest element was being camouflaged — folded into a processing fee or a higher product price — and that distorting the interest rate structure this way prevents a customer from making an informed comparison. The market did not abandon the offer; it restructured it.

What you buy today is a normal loan with a normal rate. The bank or NBFC charges its usual interest on the outstanding amount. The seller or the brand then funds a discount, roughly equal to that interest, which is applied to the purchase price. You pay the sticker price divided into instalments; the financier still earns its interest, from the merchant rather than from you. That is a legitimate three-way deal, and it is why the offer is called no-cost rather than zero-interest.

The three charges the arrangement does not absorb

The discount neutralises the interest. It does not neutralise the tax on it, nor the fees that sit outside it.

GST on the interest component. Interest was charged, so tax applies to it at the standard rate for financial services, and that tax lands on your statement. The merchant discount covers the interest, not the GST — this is the single most common surprise in a no-cost EMI.
A processing fee, typically a modest flat amount on credit-card EMI, larger on a consumer-durable loan, and itself taxable.
Foreclosure or part-payment charges if you decide to clear the balance early — the merchant funded a discount calculated over the full tenure, and closing early usually triggers a fee rather than a refund.

A worked example, in indicative numbers

Take a 1.5 tonne split at ₹40,000 on a nine-month credit-card EMI, and assume the card charges 15 % a year on a reducing balance — a plausible mid-range figure, not a quoted rate. The instalment works out near ₹4,730, the interest across the tenure near ₹2,540, and the merchant discount cancels that. What remains is the tax on that interest, plus a processing fee and tax on it.

Line	Indicative amount	Who absorbs it
Purchase price	₹40,000	You, in nine instalments
Interest over the tenure	≈ ₹2,540	Merchant, as an upfront discount
GST on that interest	≈ ₹460	You
Processing fee + tax on it	≈ ₹200–₹350	You
Real cost of the credit	≈ ₹650–₹800, near 2 % of the price	You

Every figure above is arithmetic on stated assumptions, not a tariff. Rates, fees and tenures differ by card, by financier and by campaign, and they change between one sale weekend and the next. The point is the order of magnitude: no-cost EMI on an AC typically costs one to three per cent of the purchase, which is cheap credit — and quite different from free.

The discount you gave up to get the discount

The larger cost is usually invisible, because it is a comparison rather than a charge. Merchant-funded EMI discounts and instant bank cashback offers are frequently mutually exclusive, and a cash or full-payment price is sometimes lower than the EMI price on the same listing. Before choosing the tenure, price the same model three ways: outright, on no-cost EMI, and on whatever card-linked instant discount is running. If the outright route is cheaper by more than the interest you would have saved by keeping your money, EMI is costing you after all.

The other quiet effect is on your credit line. A card EMI blocks the purchase amount against your limit for the whole tenure, not just for the month — inconvenient if the same card is your buffer for a medical bill in the same summer.

Card EMI, cardless EMI and consumer-durable loans

Three products sit behind the same banner and they behave differently:

Credit-card EMI converts an existing card transaction. No fresh credit check, fast, and the balance eats your limit.
Debit-card EMI is a pre-approved loan on your bank relationship, often requiring a small down payment.
Cardless or consumer-durable EMI from an NBFC is a fresh loan: identity check, a down payment on many schemes, a file or processing charge, and — importantly — it is reported to the credit bureaus like any other loan. Missed instalments show up on your record.

On all three, read the tenure alongside the amount. A longer tenure lowers the instalment and raises the interest the merchant must fund, which is exactly why the longest no-cost tenures tend to appear only on models the seller wants to move.

What the EMI never covers

The financed amount is the box. It is not the installation, and the gap is routinely underestimated: extra copper beyond the boxed pipe set, a dedicated point, a stand, additional drilling. Our guide to what installing a split AC in India actually costs lists those items, and they are normally payable in cash on installation day even when the machine itself is on instalments. Nor does it cover the running cost, which dwarfs the finance charge: over a decade, the electricity of a 3-star fixed-speed machine against a 5-star inverter differs by far more than any EMI fee, and our guide to what an AC really adds to an Indian electricity bill shows the sums. Buying a less efficient machine because its EMI banner looked friendlier is the most expensive move available on this page.

A short checklist before you confirm

Ask for the interest rate and tenure in figures, then check the amortisation the seller shows you.
Confirm whether GST on the interest is billed to you — assume yes unless the terms say otherwise.
Find the processing fee and the foreclosure charge before, not after.
Compare the EMI price with the cash price and with any card-linked instant discount on the same model.
Check the star rating and the model number, not the instalment. Use our BEE star label and ISEER guide to see what the rating buys you.
Keep the invoice: it is the document your warranty and any GST question will rest on.

Frequently asked questions

Is no-cost EMI on an AC genuinely free?

Close to it, but not exactly. The interest is real and is reimbursed by the seller as a discount; the tax on that interest and the processing fee remain yours. On a ₹40,000 machine that usually lands somewhere near a few hundred rupees in total, which is inexpensive credit rather than free credit.

Why is GST charged if the EMI is no cost?

Because tax follows the transaction that actually happened. The financier charged interest — a taxable financial service — and then the merchant separately gave you a discount. The discount reduces the price of the appliance; it does not undo the interest charge or the tax on it.

Does the September 2025 GST cut on air conditioners change the EMI?

It changes the price the EMI is calculated on, which lowers both the instalment and the interest funded by the seller. It has nothing to do with the tax on the interest component. What the rate change did and did not touch is set out in our guide to GST on air conditioners in India.

Can I foreclose an AC EMI early to save money?

There is usually nothing to save. The interest was already funded by the merchant for the full tenure, so early closure typically triggers a foreclosure fee without returning anything to you. Foreclose to free up a credit limit, not to reduce cost.

Is renting an AC cheaper than financing one?

Only over a short, certain stay. Across three summers or more, instalments on an owned, efficient machine beat cumulative rent comfortably, and you get to choose the star rating instead of inheriting a fleet unit — the arithmetic is laid out in our guide to renting an AC in India.
