Excel: How to Calculate Years of Service from Hire Date

You can use one of the following formulas to calculate years of service from a hire date in Excel:

Formula 1: Calculate Years of Service in Years and Months (e.g. 14 years, 2 months)

`=DATEDIF(B2,C2,"y") & " years , "& DATEDIF(B2,C2,"ym") & " months"`

Formula 2: Calculate Years of Service in Years as Decimal (e.g. 14.16944 years)

`=YEARFRAC(B2, C2)`

Formula 3: Calculate Years of Service in Years as Whole Number (e.g. 14 years)

`=INT(YEARFRAC(B2, C2))`

Each formula assume that the start date is in cell B2 and the end date is in cell C2.

The following examples show how to use each formula in practice with the following dataset in Excel:

Example 1: Calculate Years of Service in Years and Months

We can type the following formula into cell D2 to calculate the years of service for the first employee in terms of years and months:

`=DATEDIF(B2,C2,"y") & " years , "& DATEDIF(B2,C2,"ym") & " months"`

We can then drag and fill this formula down to each remaining cell in column D to calculate the years of service for each employee:

The values in column D display the years of service for each employee in terms of years and months.

Example 2: Calculate Years of Service in Years as Decimal

We can type the following formula into cell D2 to calculate the years of service for the first employee in terms of years as a decimal:

`=YEARFRAC(B2, C2)`

We can then drag and fill this formula down to each remaining cell in column D to calculate the years of service for each employee:

The values in column D display the years of service for each employee in terms of years as a decimal.

For example:

• Andy was with the company for 14.169 years.
• Ben was with the company for 3.894 years.
• Charles was with the company for 9.281 years.

And so on.

Note: You can find the complete documentation for the Excel YEARFRAC function here.

Example 3: Calculate Years of Service in Years as Whole Number

We can type the following formula into cell D2 to calculate the years of service for the first employee in terms of whole years:

`=INT(YEARFRAC(B2, C2))`

We can then drag and fill this formula down to each remaining cell in column D to calculate the years of service for each employee:

The values in column D display the years of service for each employee in terms of whole years.

Note: The last employee shows 0 years of service because he did not belong to the company for at least one whole year.
