Frequently Asked Questions — Percentage Calculator
How do I calculate what percentage one number is of another?
Divide the part by the whole and multiply by 100. For example, to find what percentage 25 is of 200, divide 25 by 200 to get 0.125, then multiply by 100 to get 12.5%. The calculator does this instantly for any numbers.
What is the formula for percentage change?
Percentage change equals the difference between the new value and the old value, divided by the old value, multiplied by 100. If a price went from $50 to $65, the change is (65-50)/50 times 100, which equals 30% increase.
How do I calculate a percentage increase or decrease?
To increase a number by a percentage, multiply it by (1 + percentage/100). To decrease, multiply by (1 - percentage/100). For example, $100 increased by 15% is 100 times 1.15, which equals $115.
