Calculating Months of Tenure

If you are in charge of tracking employees in your department or company, you might want to know if you can use Excel to calculate the months of tenure for those employees, given the date at which the employee started. This can be done very easily.

For the sake of this example, let's assume that column C contains the starting date for a list of employees. You could use the following formula in column D to determine each employee's tenure:

=DATEDIF(C3,NOW(),"M")

The DATEDIF function calculates the difference between a starting date and an ending date. The "M" used in the formula indicates that you want the result in completed months.

To calculate the average tenure for your series of employees, simply include the following formula at the bottom of column C:

=AVERAGE(C3:C174)

Of course, you should replace the range in the function (C3:C174) with the actual range of employee tenures as determined by the DATEDIF formula.
