About Us

We are a group of IT professionals and very enthusiastic to create quality free tools and content on the Internet. The main purpose of this website is to provide a comprehensive collection of free online calculators for ease of public use.

All of the calculators were developed in-house. Some calculators use open-source JavaScript components under different open-source licenses and some use particular plugins. More than 90% of the calculators are based on well-known formulas or equations from textbooks, such as the mortgage calculator, BMI calculator, etc.

If formulas are controversial, we provide the results of all popular formulas, as can be seen in the Ideal Calculator. The results of the financial calculators were reviewed by our financial advisors, who work for major personal financial advising firms. The results of the health calculators were reviewed and approved by local medical doctors. More than 99% of the descriptive content was developed in-house with a small amount of content taken from wikipedia.org under the GNU Free Documentation License.
