This site is created by a group of IT professionals who are enthusiastic in creating fast, comprehensive, convenient and free calculators. Currently, they have over 200 calculators. Their goal is to make it a one-stop go-to site for people who want to make quick calculations. All the calculators are completely free – no registration required.
The calculators are grouped into 4 sections: financial, fitness & health, math, and others. The calculations are based on well-known formulas or equations from textbooks, such as the mortgage calculator, BMI calculator, etc. Calculators such as the love calculator that are solely meant for amusement are based on internal formulas. Most of the calculators are universal – however, some, like the Income Tax Calculator, are for the United States only.
Overall, a great place to find and use a Calculator of your choice!
