Frequently asked questions

How do you find a percentage of a number?

Multiply the number by the percentage and divide by 100. For example 15% of 200: 200 × 15 ÷ 100 = 30.

How do you calculate percent increase?

(Final value − Starting value) ÷ Starting value × 100. Going from 200 to 250 is a 25% increase.
