A percentage calculator is a tool that allows you to quickly and easily calculate percentages. A percentage is a fraction that represents a part of a whole, and it is typically expressed as a number followed by the symbol “%”.

To use a percentage calculator, you will need to input the following information:

- The whole amount

- The part amount

Once you have entered this information, the percentage calculator will use the following formula to calculate the percentage:

Percentage = (Part amount / Whole amount) x 100

For example, if you want to calculate the percentage of 50 out of 100, you would input 50 as the part amount and 100 as the whole amount, and the calculator would output the result as 50%.
