### Utilizing the YEARFRAC Excel Function

Open an Excel spreadsheet. Select the cell you want to display the calculation result in.

Type **“=YEARFRAC(start_date, end_date)”** in the cell.

Replace *“start_date”* and *“end_date”* with your start/end dates.

Press enter. You’ll get a decimal number representing the fraction of years between the specified dates.

Highlight the cell and click **“Home” > “Number” > “Percentage”** to convert it to a percentage.

**YEARFRAC Excel Function** has many benefits. It can *reduce errors, increase accuracy and make complex calculations easier*. You can miss out on these benefits if you don’t use the function.

Learn **‘Using the DATEDIF Excel Function for Accuracy’** to improve your abilities to calculate fractions of years accurately.

### Using the DATEDIF Excel Function for Accuracy

The **DATEDIF** function in Excel can accurately calculate fractions of years. Here’s how: type “**=DATEDIF(**” into a cell in your worksheet. Specify the *start date*, *end date*, and *unit of time* you want to calculate in between the parentheses. “Unit” can be “y” for years, “m” for months, or “d” for days. For example, “**=DATEDIF(start_date,end_date,”y”)**” will calculate full years between two dates. Subtract the full years from the total number of years between the two dates to get the fraction.

Using DATEDIF is efficient, but it may produce unexpected results with certain date ranges. *Format your start and end dates correctly* before using them in DATEDIF. Also, *double-check your calculations against other sources for accuracy*. One user had trouble getting accurate calculations until they discovered DATEDIF. It saved them a lot of time and frustration.
