Thanks for this post. I've been looking for a good interest calculator. My coworker was using an old DOS program to do this, and no other free/os programs I found would print off a sheet of payments like this Interest(ing) Calculator does. Also open-source. Looks like it was designed by a 2nd grader using ms-paint, but still functional. Thanks!

Nevermind about my post regarding Interest(ing) Calculator. that program sucked. It won't even figure weekly payments. Interface is clunky and for some reason it takes a long time to start up. Overall, it's a poorly made program. Even has some typo's?
