Credit card
comparison calculator.

Enter your monthly spending by category. The tool compares your total annual cashback at 1%, at a single 2% flat card, and at a no-fee category stack, then shows my personal three-card stack for context (a recommendation, not a computed optimum). All math runs in your browser. Terms and bonuses change constantly, use this for comparison only.
