Frequently Asked Questions

To calculate a percentage of a number, multiply the number by the percentage and divide by 100. For example, to find 20% of 150, calculate (20/100) * 150 = 30.

To find what percentage one number is of another, divide the first number by the second number and multiply by 100. For example, to find what percentage 25 is of 200, calculate (25/200) * 100 = 12.5%.

To calculate percentage increase, subtract the original value from the new value, divide that result by the original value, and multiply by 100. For example, if a price increases from $50 to $60, the percentage increase is ((60-50)/50) * 100 = 20%.

To calculate percentage decrease, subtract the new value from the original value, divide that result by the original value, and multiply by 100. For example, if a price decreases from $80 to $64, the percentage decrease is ((80-64)/80) * 100 = 20%.
