You can use the following formulas to calculate the number of years between two dates in Excel:

**Formula 1: Calculate Full Years Between Two Dates**

**=INT(YEARFRAC(A2,B2))
**

**Formula 2: Calculate Fractional Years Between Two Dates**

**YEARFRAC(A2,B2)
**

Both formulas assume that cell **A2** contains the start date and cell **B2** contains the end date.

The following examples show how to use each formula in practice.

**Example 1: Calculate Full Years Between Two Dates**

The following screenshot shows how to calculate the number of full years between a list of start and end dates in Excel:

Here’s how to interpret the output:

- There are
**16**full years between 1/4/2005 and 1/1/2022. - There are
**15**full years between 3/15/2007 and 3/15/2022. - There are
**14**full years between 4/14/2008 and 4/18/2022.

And so on.

**Example 2: Calculate Fractional Years Between Two Dates**

The following screenshot shows how to calculate the number of fractional years between a list of start and end dates in Excel:

Here’s how to interpret the output:

- There are
**16.992**years between 1/4/2005 and 1/1/2022. - There are
**15**years between 3/15/2007 and 3/15/2022. - There are
**14.011**years between 4/14/2008 and 4/18/2022.

And so on.
