RUBS Help, Factoring the Number of occupants into Ratio

[Arif Baksh]

Hello everyone, Im sure this question has been answered however I cannot find it even after searching.

Im trying to figure out how to calculate RUBS in a small 2 Family home. 

My issue is I have found spreadsheets however, they are all password protected. I even tried to buy one which did not work out as planned. 

I just want to properly calculate the Ratio and also factor in the # of occupants to get the most accurate number as possible. 

Can anyone lead me in the right  direction?

Thanks in advance
