Credit Card Interest Calculator

Add every card you're carrying, see what they're really costing you combined, then compare up to four ways to pay them off faster: a bigger fixed payment, extra money each month, a lower rate on your worst card, or a one-time lump sum. Real numbers, side by side.

Add every card you're carrying a balance on. Give each one a name so you can track it separately, everything below compares what happens across your whole card balance, not just one card at a time.
