How to calculate a percentage

To find what a percentage of a number is, multiply the number by the percentage and divide by 100. For example, to find 10% of 200, you calculate (10 / 100) × 200, which equals 20.

Percentages are used everywhere: calculating discounts while shopping, figuring out tips at a restaurant, understanding interest rates on loans, or tracking progress toward a goal. This calculator removes the manual math so you get an instant, accurate answer.
