Calculator Soup is a free online calculator resource. Here you will find loan, mortgage, time value of money, math, algebra, trigonometry, fractions, physics, statistics, time & date and conversions calculators. Many of the calculator pages show work and/or equations that help you understand your calculations. If you don't see what you want, I am always happy to consider requests for new calculators or additional features and information. Calculator Requests and Suggestions.
You can also obtain a free online calculator that you might use on your own website. Check directions for Pop Up Calculators. If you want to use a calculator and don't find a pop up version for it, send me a request.
