Percent Greater Than

The calculator finds by what percent one number is greater than another. It works with the following formula:

$\frac{A}{B}·100\%-100\%$
where A is the larger number and B is the smaller one.

To find by what percent one number is greater than another, divide the larger number by the smaller one, multiply the result by 100% and subtract 100%.

This online calculator quickly and accurately finds the percentage ratio of the numbers and shows the result with all intermediate steps and formulas. It is useful for learning percentages in math class, as well as in everyday life and science.

Example:
Find by what percent 20 is greater than 10.
$\frac{20}{10}·100\%-100\%=200\%-100\%=100\%$
Answer: 20 is greater than 10 by 100%

Example:
