ROI stands for "Return on Investment". This is the amount your company will save by incorporating robots. A robotic system typically produces the same output as 4 welders. The annual savings (ROI) can be calculated as follows:

ROI = [(x + y) * 4 - z] * t

x = Hourly Rate of Welder

y = Equipment Cost Per Hour

z = Robotic System Cost Per Hour

t = 2080 Hours Per Year
