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”.

This example should use ROUNDUP function for months section as payback is calculated in full month; INT always rounds down, it basically works the same way as ROUNDDOWN(A1,0). This also would fix the negative issue if you replace all of the INTs with ROUNDDOWN, ROUND or ROUNDUP as appropriate
If you need completed months only
=INT(A1) & " years / " & INT((A1-INT(A1))*12) & " months"
If you need to nearest months
=INT(A1) & " years / " & ROUND((A1-INT(A1))*12,0) & " months"
If you need to count part month as complete month (as in the example given)
=INT(A1) & " years / " & ROUNDUP((A1-INT(A1))*12,0) & " 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"

NO. THIS WRONG! MONTHS ARE NOT IN TENTHS!
