Percentage Calculator is a tool that performs arithmetic operations on percentages. It can calculate the percentage of a number, the percentage increase or decrease between two numbers, and the percentage of a part of a whole. The tool is useful for calculating discounts, taxes, tips, and other percentage-based calculations.

Percentages are often used in finance, business, and everyday life to represent a fraction of 100. The calculator provided automatically converts the input percentage into a decimal to compute the solution. However, if solving for the percentage, the value returned will be the actual percentage, not its decimal representation.

For example, if you want to calculate what percentage of 50 is 10, you would enter 10 in the “is what percent of” field and 50 in the “of” field. The calculator would return 20%, which is the percentage of 10 in 50
