About

I am an individual IT Professional enthusiast in creating quality and easy to use free tools and content on the Internet. The sole purpose of this website is to provide the ease and comprehensive collections of free online calculators for public use. This site was launched on calculatorsempire.net in 2025.

The calculators on this site were categorized into 4 categories: financial, Math, Fitness & Health, and Others. All of the calculators were developed by my self. Some calculators might use open-source JavaScript componenet under fair use of open-source licenses. More then 95% of the calculators are based on well known standard formulas or equations from the textbooks. Such as BMI calculator, mortgage calculator, etc.

If formulas are controversial, we have adopted the most standard one for the results for the Ideal Calculation results. The results of the some technical or financial calculators were reviewed by the students of Harvard, MIT, Stanford, etc. who work for major personal financial advising firms. The results of the health calculators were not reviewed and approved by local medical doctors. More than 99% of the descriptive content was developed by myself with a small amount of content or information taken from wikipedia.org under the GNU Free Documentation License.
