Frequently Asked Questions
What does this calculator measure?
It calculates the percentage increase from an original value to a higher new value. The formula used is ((new value − original value) ÷ original value) × 100. For example, if a product sold 200 units last month and 250 units this month, the percentage increase is ((250 − 200) ÷ 200) × 100 = 25%.
What is the difference between percentage increase and absolute increase?
Absolute increase is the raw numerical difference between two values — for example, sales growing from 200 to 250 is an absolute increase of 50. Percentage increase expresses that same change as a proportion of the original value, so 50 ÷ 200 = 25%. Percentage increase is more meaningful when comparing changes across different scales or time periods.
Can I use this for salary or price increase calculations?
Yes. This calculator works for any scenario where you need to know how much a value grew in percentage terms. Common uses include calculating salary raise percentages, tracking price increases on goods and services, measuring revenue growth between business quarters, monitoring exam score improvements, and analyzing subscription or user growth rates.
What happens if I enter a smaller new value than the original?
If the new value is smaller than the original, the formula returns a negative result, which represents a percentage decrease rather than an increase. For example, entering 200 as the original and 150 as the new value returns −25%. For dedicated decrease calculations, use the Percentage Decrease Calculator on this site.
Is this different from calculating a percentage of a number?
Yes, these are different calculations. Percentage increase measures how much a value grew relative to its starting point. Percentage of a number finds what a given percent of a fixed value equals — for example, 20% of 500 = 100. Use the Percentage of Number Calculator for that type of problem.
