Frequently Asked Questions
How do I calculate a percentage of a number?
Multiply the number by the percentage divided by 100. For example, 20% of 500 is 500 × (20 / 100) = 100.
How do I calculate what percent one number is of another?
Divide the first number by the second number and multiply by 100. If 150 is part of 500, then (150 / 500) × 100 = 30%.
How do I calculate percentage increase or decrease?
