Percentage Increase Calculator
Calculate the percentage increase from an original value to a new value. Formula: ((new − original) ÷ original) × 100.
How the percentage increase formula works
% Increase = ((New Value − Original Value) / Original Value) × 100
The result is the percentage by which the value increased. If the new value is less than the original, use the percentage decrease calculator instead.
Understanding percentage increase and when to use it
Percentage increase is one of the most common ways to express growth. When a quantity goes from one value to a higher value, the percentage increase tells you how much it grew relative to the starting point. For example, if your salary increases from 50,000 to 55,000, the increase is 10%—meaning you now earn 10% more than before.
The formula works by first finding the absolute increase (new value minus original value), then dividing by the original value to express it as a proportion, and finally multiplying by 100 to convert to a percentage. This ensures that the same absolute increase represents a smaller percentage when the original value is larger. A 10 increase from 100 to 110 is 10%, but from 1000 to 1010 it is only 1%.
Common uses include tracking price increases, salary raises, population growth, revenue growth, and any metric where you want to compare before and after. The percentage increase calculator handles the math for you—just enter the original and new values. If the new value is lower than the original, the result would be negative; in that case, use the percentage decrease calculator for a clearer interpretation.
