Each institution’s lowest ongoing purchase APR on a regular card (not an introductory or balance transfer rate): usually its best-credit rate. A rate that needs another account or similar says “with conditions”; More filters can leave those, or cards with an annual fee, out. Secured, business and credit-builder cards are left out. Carrot Score rates each institution on all its CD, savings, auto loan and credit card rates. How we rank
