How to Calculate Percentage

A percentage is a number expressed as a fraction of 100. To calculate a percentage of any number, multiply the number by the percentage and divide by 100. For example, 25% of 400 = (25 × 400) ÷ 100 = 100.

To find what percentage one number is of another, divide the first number by the second and multiply by 100. For example, 400 out of 500 = (400 ÷ 500) × 100 = 80%.
