How to choose a credit card in India based on how you spend

Start with your own spending, not the card

Before you look at a single card, write down roughly what you spend in a normal month and where it goes. Group it into a handful of buckets: groceries and daily needs, online shopping, food delivery, fuel, utility bills, travel, and everything else.

This matters because rewards are almost never flat. A card may pay a high rate on one online platform and a fraction of that elsewhere. If most of your money goes to fuel and bills, a shopping-focused card can leave you with very little back, however good its advertisement looks.

Work out the net value, not the reward rate

The number that matters is what you actually get after paying for the card. Take the rewards you would earn in a year on your own spending, convert them to rupees at what they are genuinely worth when redeemed, and subtract the annual fee (with GST) and any other regular costs.

A card with a modest reward rate and no fee can beat a glamorous card with a large fee if your spending is small. This is the calculation the Card Finder tool does for you: it takes your monthly spending by category and ranks cards by net rupee value rather than by the size of the reward rate.

• Reward points are not always worth one rupee each. Check the redemption value, and whether points can only be spent on a limited catalogue.
• Caps matter. Many cards limit monthly rewards or cashback in a category, which changes the real return on heavy spending.
• Exclusions matter. Rent, wallet loads, insurance and fuel are often excluded from the headline rate.

Look at fees the way the bank does

Most cards have a joining fee and an annual fee, and many waive the annual fee if you spend a set amount in a year. A waiver is only useful if you would have spent that much anyway. Spending extra to earn a waiver usually costs more than the fee itself.

Also read the smaller charges: the interest rate on unpaid balances, the late payment fee, the cash withdrawal fee and the foreign-currency markup if you travel or shop from overseas sites.

Match the card to your situation

• First card or no credit history: a low-fee or lifetime-free card, or a card secured against a fixed deposit, is easier to get and safer to learn on.
• Occasional spender: a lifetime-free card with a decent base reward rate, so you never pay to hold it.
• Frequent traveller: a travel card can pay off through lounge access and low foreign-currency markup, but only if you use the benefits.
• Mostly bills and fuel: look for a card with a surcharge waiver on fuel and reward rates on utility bills.

The rule that matters more than any card

Every reward calculation assumes you pay the full statement balance by the due date. Interest on unpaid balances on Indian credit cards is high, often in the range of 3 to 3.5 percent a month, and it will wipe out any reward you earn many times over. If you expect to carry a balance, the best card is the one with the lowest interest rate, not the highest rewards.
