## How to calculate percentage change in Excel?

### With the Percent Change function

While there is more than one way to calculate percentage change in Excel, the simplest method to do this is to call the Percent Change function, which takes two arguments and compares them directly.

Only you must enter the two values, in separate cells, and select the cell where the result will go. Write or paste there: «= PERCENTCHANGE(old value, new value)” – for example, “= PERCENTCHANGE(A1, A2)«.

Immediately the function will do the calculation, and it will tell you what is the difference between both numbers..

Eventually, you can use a shorthand formula to find the percentage change, like this: =PERCENTCHANGE(10,15). As you type this, the result will be 50%, which is the percentage change already known. This would return a result of 50%, indicating that the new value is 50% higher than the old value. That would indicate, without going any further, that sales grow by 50% between 10 a.m. of the first month and 3 p.m. of the second.

### With a pivot table

As we said before, the other option is to resort to a magical instrument, such as pivot tables. We believe that you should choose this alternative if the numbers to be compared are more than two or three. Basically, this means that, in rare cases, it’s best not to stop and go to pivot tables.
