How to Calculate Percentage Change
The percentage change between two numbers is found by dividing their difference by the number that is being changed from, then multiplying that result by 100%.
It should be noted that the percent change is measured FROM the first value – a change from 50 to 75 is a change of 50% (25 is the difference between the two numbers, and 25 is 50% of 50), while a change from 75 to 50 is a change of -33.3% (25 is still the difference between the two, however 25 is 33.3% of 75).

What is a percentage?
A percentage is a number expressed as a fraction of 100.
If a number is 100% (100 percent), then it is a “whole” – the same as one.
If a number is 50%, then it is a half – the same as 0.5 or 1/2.
If a number is 400%, then it is 4 times, the same as 4.
