title: Open source loan amortization schedule
body: <p>I suppose this is a follow-up to <a href="https://stackoverflow.com/questions/1962057/are-there-any-bsd-or-lgpl-libraries-for-calculating-amortization-schedules">this previous SO post</a>, but I have been searching for an open-source library that is usable with Objective-C that will take loan parameters and generate an amortization schedule.  I know there are tons of iPhone apps out there that generate amortization schedules, but what libraries do they use?</p>
  
  <p>Thanks,</p>
