Frequently asked questions
How do you 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 you calculate percentage increase?
Subtract the old value from the new value, divide by the old value, then multiply by 100. Going from 50 to 65 is (65 − 50) ÷ 50 × 100 = 30% increase.
What is the difference between percent and percentage points?
Percent describes a relative change. Percentage points describe the plain difference between two percentages: moving from 10% to 12% is +2 percentage points, but a 20% increase.
