Reducing changeover time is very similar to reducing downtime because changeover time is a type of downtime. The formulas are the same, but the one difference is the input in the number of minutes on average you can reduce your changeover times. Changeover Time ROI Formula: (Gains – Costs)/Costs = ROI For example, if you can reduce changeovers from 45 minutes to 27, the formula would look like this. Reduce Changeover Time ROI Calculation: ((45 – 27) * 10)/60 = 3 Hours saved per day $75*3 = $225.00 saved per day ($225 – $57.69)/$57.69 = 290% ROI
