About the Percentage Increase Calculator
Use this calculator to increase a number by a percentage — a pay rise, a price rise, population growth — or to find the percentage increase from one value to another.
How does the Percentage Increase Calculator work?
To increase a number by a percentage, multiply it by (1 + percentage ÷ 100). To find the increase between two numbers, divide the difference by the original and multiply by 100.
Percentage Increase Calculator formula
new value = original × (1 + p ÷ 100)
% increase = (new − original) ÷ original × 100Example
A $80,000 salary with a 4% rise: 80,000 × 1.04 = $83,200.
Rent going from $500 to $540 a week is an 8% increase: 40 ÷ 500 × 100 = 8.
