Welcome to one of the best collections of free online Financial, Business and other Internet calculators. We've been developing online calculators since 1998 and currently have 87 calculators on this website with more in development.

Our original passion was financial calculators, and one of our favorites has always been the Financial Programmable Calculator you see below. Over time, we've expanded the range of calculators to many other categories and we hope you find this site to be a useful resource.

Right now, we're working on more time-related calculators. If you'd like to see any other types of calculators, please click the contact button at the top of the page and let us know.
