1. Start with the best cash price, not the sticker price

If the product is ₹60,000 but available for ₹56,000 through a non-EMI discount, then ₹56,000 is the relevant comparison price. A no-cost EMI totalling ₹60,000 has effectively cost you ₹4,000 more than that alternative before processing fees or taxes.

Tip: Opportunity cost matters: the discount you give up is part of the EMI decision.

2. Add processing fee and applicable tax

A one-time processing fee can make a small EMI more expensive on a percentage basis, especially for short tenures or low-value purchases. Applicable taxes on processing and finance-related charges can add further cost. Use the amount actually charged on the statement.

Tip: Tiny fees matter more when the financed purchase is small or the tenure is short.

3. Consider card-limit and cash-flow impact

An EMI can occupy a large portion of the card limit for several months, reducing flexibility for emergencies and potentially increasing utilisation. Also ask whether the monthly EMI fits comfortably after rent, existing EMIs and essentials. A financing offer can be cheap but still unaffordable.

Note: Affordable price and affordable monthly cash flow are two different tests.

4. Pre-closure can change the economics

If you repay the EMI early, the issuer can apply pre-closure or foreclosure rules. Merchant discounts already received may not be recalculated the way you expect. Read the exit terms before accepting a long tenure, especially if you think you may repay early.

Tip: A cheap plan is only cheap if you understand both entry and exit costs.
