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 50 is of 200, divide 50 by 200 and multiply by 100, giving you 25%.
How do I calculate percentage increase or decrease?
To calculate percentage change, subtract the old value from the new value, divide by the old value, and multiply by 100. For example, if a price increases from $80 to $100, the increase is ((100-80)/80) × 100 = 25%.
