Is there any cost advantage (ROI) calculator excel sheet

Raja Nagendra Kumar

I am looking for an Excel template that takes the number of site engineers and workplaces of big AECO companies and calculates if BB is used, and what is the cost-saving yearly.

I found this link has a bit, in line with what I am looking for, which helps in ROI calculations

However, I am unsure what formula is used to show the end savings of 11x, and taking more parameters in calculations can better capture all the realistic organization parameters, also, need an option to calculate ROI INR.
