BadPlastic helps you keep an eye on your credit card debt with style and minimum effort. Tell it about your cards, add the statements as they arrive in the mail (or get them from the attic in any order you like), and BadPlastic will: Show a timeline of card balances, scaled according to the card limit at the time of each statement Allow you to zoom in and out of the timeline to see the required time period Calculate APR from monthly percentage rate and vice versa, to simplify statement entry Approximate missing balances so that the timeline graph appears contiguous (useful when entering statements in random order) Display each card's APR so that you know which card is the most expensive Show percentage of available credit used which can affect your credit rating Estimate number of payments left to clear card debt Show you the approximate date of the last payment for each card, based on the last payment amount Estimate when you will completely pay off your credit card debt, giving you a worthy goal
