Two of the most frequently used tools in Excel are the
Sum functions. These functions let you count and sum cells based on one or multiple different criteria.
COUNT in Excel
You can use the
COUNT function to count the number of cells containing numbers.
How to use COUNTIF
If you need to count cells based on a specific criteria then use the
COUNTIF function. An example would be if you only want Excel to count the cells with values greater than 5.
How to use COUNTIFS in Excel
If you need to count cells based on multiple criteria then use the
COUNTIFS function. An example would be if you want Excel to count all cells with values greater than 5 and that are Red.
SUM in Excel
If you want to add multiple numeric values within different cells you can use the
SUM function. In order to do this do it like in the example below:
How to use SUMIF
In order to sum cells based on only one criteria then use the following
SUMFIF function with two arguments.
To sum cells based on one criteria use the following
SUMIF function with three arguments, the last argument is to range the sum. An example would be if you only want Excel to sum the values of cells that are Blue.
How to use SUMIFS in Excel
In order to sum cells based on multiple criteria, use the following
SUMIFS function. The first argument is the range to the sum.
AVERAGEIF and AVERAGEIFS in Excel
Next to the COUNT and the SUM function explained above, you can average numbers in a range of cells with the
With these also you can add one or multiple criteria to make sure you only select a certain subset of cells in your range that meet your criteria.
You now know how to use some of the most used and most powerful formulas in Excel.
