CalcSolver is a free online calculator site. We build fast, simple calculators for maths, finance and everyday problems — no sign-up, no download, no app.
What we do
We make calculators that show their working. Every tool gives you the answer and the steps behind it, so you can check your result and learn how it was worked out. Our tools cover algebra, fractions, finance, geometry and more, and they all run in your browser. You can browse our free tools without signing up. If fractions are your focus, start with the fraction guide. The CalcSolver guide explains how to use every calculator on the site.
Why free?
Calculators should be available to everyone. We keep CalcSolver free so students, teachers and anyone who needs a quick answer can use it without paying or signing up.
