Before you pay, see which card in your wallet earns the most: per-category rates, monthly caps and milestones, shown as plain math. No bank login, no card numbers. Free, local, no account.
Cardpick only does the arithmetic on the rates you typed. It is not financial advice: rates, caps and milestones change, so check your card's current terms.
Cardpick is for anyone who forgets which of their cards pays most where. Enter each card’s rates per category, caps and spend milestones, then pick an amount and a category: every card is ranked by what it gives back, with the math shown.
It runs in the browser with no account, no bank login and no card number field. Your cards stay in this browser on this device and are never sent to a server; export a JSON backup now and then.
Example: 10% on dining with a nearly used monthly cap versus 1.5% on everything. Enter tonight’s dinner and see which card earns more. Arithmetic, not advice.
