Frequently asked questions
How do I calculate a percentage of a number?
Multiply the number by the percentage and divide by 100. For example, 15% of 200 is 200 × 15 ÷ 100 = 30.
How do I find what percentage one number is of another?
Divide the first number by the reference number and multiply by 100. For example, 25 is 20% of 125.

Subtract the original value from the new value, divide by the absolute original value, and multiply by 100. A positive result is an increase and a negative result is a decrease.
What is the difference between percentage and percentage points?
