The formula for calculating percentage change is shown below:-

x = (V_{2} - V_{1}) / V_{1} * 100

Where,

x - Percentage change in %

V_{2} - New value

V_{1} - Old value

If the calculation result is positive, we say, there is a percentage increase of *x%*. If the result is negative, there is a percentage decrease of *x%*.

Sample calculations: Percent change from 70 to 56 Percent change from 72 to 90 Percent change from 36 to 63 Percent change from 5 to 8 Percent change from 3 to 4 Percent change from 0 to 2 Percent change from 18 to 45 Percent change from 80 to 64 Percent change from 16 to 0 Percent change from 640 to 480
