Datedif and If statement in Excel

Question

I want to create an Excel formula that allows me to calculate the datedif of the month (ie Date of Expiry - Today's Date). Which I have done as seen below:

This is my formula:

=IFERROR(DATEDIF($F$1,C4,"m") & " Months", "Already Expired")

However, I want a formula that can take note of the (s) in Months if the months left is only 1 Month. (Ie I do not want the s behind the Months if the "m" in datedif is just 1 month difference.) How do I achieve that?

Answer 1

I would write the unit into the cell format, not the formula. The formula should produce an integer and the cell format should be Custom [=1]0 "month";0 "months" .

To test, format a cell as described above and enter any number. The cell will display the number and the word "moth" or "months", depending upon the value you entered.
