02Interest calculation methods

Six ways the bill gets computed

The same APR can produce different charges depending on the method. The friendliest is the adjusted balance; the harshest is barred by law.

03Cards worth comparing

Lower the rate, lower the damage

These are illustrative examples for now. When you add real cards, this line will note that SimpleAPR may earn a commission if you apply through some links — at no cost to you — and that it never changes which cards are shown or how they're ranked.
