Who We Are

Calculate Percentage is a free online resource dedicated to making percentage calculations simple, fast, and accessible for everyone. Whether you are a student working through a maths problem, a professional tracking business growth, a shopper calculating a discount, or simply someone trying to make sense of a number, our tools and guides are here to help you get the right answer instantly.

We built this site because percentages show up everywhere — in exam results, salary increases, bank interest, price tags, business reports, and daily decisions — yet many people still find them confusing or time-consuming to work out. Our goal is to change that by providing clear, reliable tools and easy-to-understand explanations that anyone can use.

Our Mission

Our mission is to make percentage calculations effortless for everyone, regardless of their mathematical background. We believe that getting accurate results should not require a maths degree or a complex spreadsheet. Every tool and article on Calculate Percentage is designed with one principle in mind: clarity first.

We want you to not only get the right result but also understand the method behind it. That is why every calculator on our Site is accompanied by a plain-English explanation of the formula used and, where possible, a worked example you can follow step by step.
