1. Start with how you actually spend

List your normal monthly categories: groceries, online shopping, fuel, travel, dining, utilities, rent and other recurring payments. Then identify which of those categories the card rewards and which it excludes. A card is valuable only where your genuine spending overlaps with its earning rules.

Tip: Do not choose the card first and then change your life to fit it.

2. Calculate realistic annual value

Estimate eligible spend, apply actual reward rates and caps, convert points to realistic redemption value, add milestone benefits you will naturally earn, then subtract annual fee and redemption charges. This gives you a rough net annual value instead of a marketing headline such as 10X rewards.

Tip: Use expected rupees of value, not points, multipliers or “up to” claims.

3. Check the non-reward costs and restrictions

Review annual fee, forex markup, cash-advance terms, EMI charges, rent or education charges, lounge-spend conditions, redemption fees, network acceptance and other terms relevant to you. A card with the highest reward rate can still be a poor fit if categories are capped or benefits require unnatural spending.

Note: Rewards are only one line in the card economics.

4. Protect against the biggest cost: revolving debt

Any reward calculation assumes you are not paying high finance charges on carried balances. If you regularly pay interest, reward optimization becomes secondary to debt repayment. Use Varsity to understand the framework. Use GainFair card advisor to apply current card data to your income, spending and preferences.

Tip: The best reward card is still expensive if you carry high-interest debt.

5. Quick check

A card advertises 5% rewards but caps them at ₹500 a month, charges a high annual fee and excludes your biggest spending categories. What should you do?
