What Is a Free Percent Change Calculator?
A Free Percent Change Calculator is an online tool that calculates the percentage change between an original value and a new value. It is useful for quickly determining whether a value has increased or decreased and by what percentage.
How Does a Percent Change Calculator Work?
The standard formula is:
Percent Change = [(New Value − Original Value) ÷ Original Value] × 100
For example, if a product price increases from $80 to $100:
[(100 − 80) ÷ 80] × 100 = 25%
So, the price increased by 25%.
Example of a Decrease
If a value decreases from 200 to 150:
[(150 − 200) ÷ 200] × 100 = −25%
This means the value decreased by 25%.
