A percentage is a way of expressing a number as a fraction of 100. Percentages are commonly used for discounts, taxes, interest, statistics, price changes, grades, business calculations, and many everyday situations.

How to Calculate a Percentage of a Number

To find a percentage of a number, convert the percentage into a decimal and multiply it by the number.

Percentage of a Number = (Percentage ÷ 100) × Number

For example, 20% of 200 is:

(20 ÷ 100) × 200 = 40

How to Find What Percentage One Number Is of Another

Divide the first number by the second number and multiply the result by 100.

Percentage = (First Number ÷ Second Number) × 100

Percentage change measures how much a value has increased or decreased compared with its original value.

Percentage Change = ((New Value − Original Value) ÷ Original Value) × 100
