Calculate an Investment's Due Date in Excel

The EDATE function can be used to calculate a due date of an investment that falls on the same day of the month as the date it was issued.

The syntax for the EDATE function is:

= EDATE ( Start_date , Months )

Start_date - the start date of the project or time period in question.

Months- the number of months before or after the Start_date.

Example: Calculate an Investment's Due Date

For help with this example, see the image above.

  1. Enter the following data into the appropriate cell:

    D1 - Start Date:
    D2 - Months:
    D3 -Due Date:
    E1 - 7/6/2009
    E2 - 7

    Note: If the date in cell E1 does not appear correct, check to see that the cell is formatted for dates.

  2. Click on cell E3 - the location where the results will be displayed.

  3. Click on the Formulas tab.

  4. Choose Date and Time functions from the ribbon to open the function drop down list.

  5. Click on EDATE in the list to bring up the function's dialog box.

  6. Click on the Start_date line in the dialog box.

  7. Click on cell E1 in the spreadsheet to enter that cell reference into the dialog box as the Start_date argument.

  8. Click on the Months line in the dialog box.

  9. Click on cell E2 in the spreadsheet to enter that cell reference into the dialog box as the Months argument.

  10. Click OK in the dialog box.

  11. The due date of the investment - 2/6/2010 (February 6, 2010) - appears in cell E3 which is 7 months after the start date.

  12. If a number, such as 40215, appears in cell E5 its likely that the cell has General formatting applied to it. Change the cell formatting to Short Date to get the results to appear correctly.

  13. When you click on cell E3 the complete function = EDATE ( E1 , E2 ) appears in the formula bar above the worksheet.

Note: The EDATE function can also be used to find a date in the past - such as the day work began on a project. To do so enter a negative number for the Months argument and use the project's due date for the start_date argument.
