What is this tool?
Handles the three most common percentage calculations in one place: finding a percentage of a number, figuring out what percentage one number is of another, and calculating percentage change between two values.
How to use it
Pick the calculation you need from the tabs, enter your numbers, and the result appears instantly as you type.
Percentage change and percentage difference are often confused — this tool's "% change" tab specifically measures how much a value increased or decreased relative to its starting point, which is usually what people actually mean by "percent change."
