Which card should you actually pay with?
India has 40-odd credit cards within arm's reach of any serious spender, and almost no honest way to compare them, so people leave cashback and points on the table every month. This tool asks how you spend, and answers which card leaves you better off. It ranks cards by net value (rewards earned minus the slice of the annual fee that month), shows the best card you already own, and quietly points at the one you should probably apply for.
- Pick a category (groceries, flights, food delivery) and an amount
- Every card scored on net value: rewards earned, fee impact applied
- Side-by-side comparison across the whole wallet, recalculated live
