What card should I get next?
Enter roughly what you spend each month and tick the cards you already carry. Every other card in the catalogue is scored on what it would add — only where it beats what you already earn, spending caps honoured, rotating categories not credited — and then its annual fee is taken off. Nothing here is sponsored, and no card pays to be listed.
This calculator needs JavaScript. Every card has a page saying what it earns in a year on an illustrative household's spending.
Nothing you choose here leaves this page: your picks live in the address bar after the #, which a browser never sends to a server — so a link to this page carries them, and nothing else does. How the numbers are worked out.
Do this at every checkout, automatically.
Cardful remembers your cards and ranks them at the store you are on.
