Looking for formula help. I have one cell that lists employee tenure, another that lists committed hours, I want to return hours with a new hire factor to accurately predict working hours equivalent to seasoned staff. Using this scale, 2 week tenure = 50%, 3 week = 62.5%, 4 week =75%, 5 week = 87.5% and 6+ weeks = 100%. So if the staff committed to 40 hours and they have a tenure of 2 weeks with the company I want the return to be 20 hours. Can anyone tell me which formula would work best for this?
