7 Things to Know Before Applying for a Cashback Credit Card

1. Check the cashback cap, not just the rate

A card that advertises 5% cashback sounds great, until you read that the benefit stops at a fixed amount per month or per quarter. Caps are the single biggest reason people earn less than they expected.

Look for three things: the cap per month or quarter, whether it applies to each category or to the whole card, and whether the cap resets on your statement date or on the calendar month. Then multiply your own spend by the rate and compare it with the cap. If your spend is higher than the cap allows, the extra money earns little or nothing.

For example, 5% with a ₹500 monthly cap means you earn at most ₹500 a month on that category, even if you spend ₹50,000 there.

2. Read the exclusions list

Most cashback cards do not reward every kind of spend. The usual exclusions or reduced-rate categories in India include rent, fuel, wallet loads, government and tax payments, and often utilities, insurance, education fees, gold and jewellery. Rules differ by card, so never assume.

If a big part of your monthly spending is in one of these categories, a card that excludes it will earn you very little however attractive its headline rate looks. Our guide to credit cards for education fees shows how few cards still pay rewards on a category that is commonly excluded.

3. Work out the annual fee against your real cashback

Many cards are lifetime free. Others charge a joining or annual fee, plus 18% GST on it, and offer a fee waiver if you spend a set amount in a year. A fee is not automatically bad. It is worth paying only when the extra cashback is clearly larger.

A simple test: take your estimated yearly cashback after caps, subtract the fee with GST, and compare the result with a lifetime free card. Also check whether the fee waiver spend target is something you would reach anyway. Chasing extra spending just to waive a fee is a loss.

Numbers are made up to show the method. Use your own spends and the card's current fee.

4. Find out where the best rate really applies

Top rates are often tied to a specific app, platform or merchant, such as one shopping site, a food delivery app or a particular payment app. Outside it, the card may give only 1% or less.

Ask yourself honestly: do you already spend there every month? If the 5% category is a store you rarely use, the card's everyday rate is the one that matters. Comparing cards on your own spending mix, as the cashback card comparison calculator does, shows this quickly.

5. Never carry a balance: interest beats cashback

Cashback only makes sense if you pay your full statement amount by the due date. Credit card interest in India is commonly around 3.5% to 4% a month, which is roughly 42% to 48% a year. Missing a due date also usually adds a late payment fee and interest from the purchase date, because the interest-free period is lost.

If you often pay only the minimum due, a cashback card is the wrong tool. Set up auto-pay for the full amount, or at least a reminder a few days before the due date.

6. Match the card to your spending pattern

The best cashback card is the one that fits how you live, not the one with the highest percentage in an advertisement. Before applying, list your typical monthly spends: online shopping, groceries, food delivery, travel, bills, fuel and offline shopping.

Then see which card rewards the largest slice of that list. A person who orders groceries and food online every day needs a very different card from someone who spends mostly in stores. Also consider how you will receive the reward: as a statement credit, as points that need redeeming, or as vouchers, because some forms are worth less than a rupee each.

7. Check eligibility, credit score impact and changing terms

Banks usually look at your income, credit score and existing debt. A score of about 750 or above generally improves your chances, although every issuer sets its own rules. A formal application leads to a hard enquiry on your credit report, and several applications within a short time can lower your score and look risky to lenders. Apply only for cards you will use.

Finally, remember that terms change. Banks revise cashback rates, caps, fees and exclusions, so read the latest Most Important Terms and Conditions (MITC) document before you apply, and review your statement after the first few months.
