About Us

As fervent IT professionals, we wanted to create a platform that would allow us to share free online calculators for everyone to utilize. This site boasts a comprehensive collection of tools, ranging from simple to complex engineering calculators.

Here are a few facts about the calculators you will find on our website:

  • Our team has internally developed more than 98% of the calculators we provide.
  • Over 90% of the calculators are based on well-known formulas or equations (i.e. mortgage and loan calculators, BMI calculator, math and engineering calculators, etc.)
  • Some calculators use open-source JavaScript components under various open-source licenses

Our rights to the material provided are below:

Much of the descriptive content was developed internally by our team of specialists. However, approximately 5% of the content was used from Wikipedia.org under the GNU Free Documentation License.

The content description of the financial calculators was created and/or reviewed by our financial advisors with actual data from the following public sites: www.irs.gov and www.gov.uk

All other content descriptions were created by our team of engineers.
