How to Add Months to Date in Excel (With Examples)


You can use the EDATE() function in Excel to quickly add a certain number of months to a date.

This formula uses the following basic syntax:

EDATE(start_date, months)

where:

  • start_date: The starting date
  • months: The number of months to add to the starting date

For example, we can use the following syntax to add 10 months to the date in cell A1:

=EDATE(A1, 10)

The following example shows how to use this function in practice.

Example: Add Months to Date in Excel

Suppose we have the following list of dates in Excel:

We can type the following formula into cell B2 to add three months to the date in cell A2:

=EDATE(A2, 3)

We can then drag and fill this formula down to each remaining cell in column B:

By default, Excel will display the dates in a numerical format.

To display the dates in a recognizable date format, highlight the cells in the range B2:B11, then click the Number format dropdown arrow and choose Short Date:

The dates will then be formatted correctly:

Excel add months to date

Notice that each of the values in column B show the value of the date in column A plus three months.

Note that you can also use negative numbers to subtract months from a date.

For example, we could type the following formula into cell B2 to subtract three months from the date in cell A2:

=EDATE(A2, -3)

Excel subtract months from date

Now each of the values in column B shows the value of the date in column A minus three months.
