This tutorial will demonstrate how to calculate years of service in Excel and Google Sheets.
Calculate Years & Months of Service
To calculate the number of years between dates use the DATEDIF Function with criteria “y”:
You can calculate the number of excess months using the criteria “ym” with the DATEDIF Function:
Now we can output the years of service in a text string:
=DATEDIF(B3,C3,"y")&" Years and "&DATEDIF(B3,C3,"ym")&" Months "
Rounding Service Months
Your service calculation might require rounding months. To round months, you can use the EOMONTH Function to return the last day of a month.
You can round to the previous month:
Or round to the end of the current month:
By adding 1 to the last day of a month, you can calculate the first day of the next month:
With month rounding, you can count partial months as full months, or not count partial months at all.
Calculate Years & Months of Service in Google Sheets
All of the above examples work exactly the same in Google Sheets as in Excel.
