What Is Average in Excel?
The average for numerical values is calculated by adding all the numbers and dividing the sum of those numbers by the count of numbers.

Here’s the mathematical formula for that:
By default, when you calculate the average, Excel ignores any blank cells but it does consider the cells containing zeros. You can make it ignore zero cells, too, as we’ll explain below.
