Percentage change is used to compare two different values of the same thing whose value changes over time. e.g., change in the price of apple per kilo at the start of the year and end of the year.
Find percentage change
The formula for calculating percentage change is shown below:-
x = (V2 - V1) / V1 * 100
x - Percentage change in %
V2 - New value
V1 - 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%.
