Great Online Financial Calculator

Although a 'For Sale' service, WebWinder has over 100 financial calculators from Home Mortgage, Car Loans, Future Value of Money, etc. It also has calculators for comparing two purchases like 'do I keep my car or buy a new one' ... incorporating maintenance, depreciations and lots more costs we forget. I used it to find cost difference of upgrading a three year old car and it validated the new car would cost twice as much over a 5 year period than keeping our current vehicle. Link http://www.webwinder.com/
