Frequently Asked Questions
How do I calculate a percentage?
To calculate a percentage, divide the value by the total and multiply by 100. For example, to find what percentage 25 is of 200: (25 ÷ 200) × 100 = 12.5%.
How do I calculate a percentage increase?
To calculate a percentage increase, subtract the original value from the new value, divide by the original value, and multiply by 100. For example, if a value increases from 80 to 100: ((100 - 80) ÷ 80) × 100 = 25% increase.
How do I calculate a percentage decrease?
To calculate a percentage decrease, subtract the new value from the original value, divide by the original value, and multiply by 100. For example, if a value decreases from 100 to 80: ((100 - 80) ÷ 100) × 100 = 20% decrease.
How do I find a percentage of a number?
To find a percentage of a number, divide the percentage by 100 and multiply by the number. For example, to find 15% of 200: (15 ÷ 100) × 200 = 30.
What is the difference between percentage and percentage points?
A percentage is a relative measure, while a percentage point is an absolute measure. For example, if an interest rate increases from 5% to 7%, it's a 2 percentage point increase, but a 40% relative increase (because (7-5)/5 = 0.4 or 40%).
