About

These are HTML calculators built to run on any device with a browser, developed to be accurate, robust, and easy to use.  All of them are free to use online.

The Basic Calculator lives on the home page.  It's a four-function calculator with calculation history, memory, percent, plus more, and it is fully resizable to whatever screen it's on.  It holds up in the office, classroom, and at home.

How This Stays Free

Banner ads are how the site pays for itself.  No account to create, nothing to buy, and nothing about you sold to anyone.  Open the page and calculate.

Custom Work

These calculators can be embedded in your own website.  Past projects have included custom builds with corporate branding, dedicated calculator panels, and one-off features tailored to a business.  Get in touch if you have something in mind.
