Displaying a Number as Years and Months

by Allen Wyatt
(last updated January 6, 2018)


Robert has a formula that determines the payback period for certain investments. For instance, with $20,000 investment in energy-savings equipment and an annual energy savings of $3000, the simplistic payback period to recoup the investment is 6.6667 years. Robert wonders how he can make this payback period (6.6667) show as years and months instead of as a decimal number.

This can be done by simply multiplying the portion of the answer at the right of the decimal point by 12, which results in a number of months. Here is one way to get the desired result, assuming that the payback result is in cell A1:

=INT(A1) & " years / " & INT((A1-INT(A1))*12) & " months"

With the value 6.6667 in cell A1, the formula would return “6 years / 8 months”.

You are right, months are not in tenths but the formula doesn't do that. Try with 6.92 and you get 6 years / 11 months. So the formula is all right BUT ONLY FOR POSITIVE NUMBERS. For positive as well as negative numbers use this formula:

=TRUNC(A1) & " years / " & TRUNC((A1-TRUNC(A1))*12) & " months"
