  5. DO A SAMPLE FOR YOUR APPLACATION. Step 9. Add cost of VFD to Installation Cost $24,140.00 VFD Cost $18,000.00 Install Cost $42,140.00 Total Cost Step 10. Divide total cost by annual savings= return on investment in years $42,140.00 Cost/Savings $20,932.78 2.01 ROI in years In the example ROI has been calculated with one pump in operation, the cost of two 125 HP VFD units and Installation (the second is for the standby pump). CLICK TO RUN APPLACATION. THE SPREADSHEET IS MADE FOR A PUMP RUNNING WITH A DISCHARGE VALVE THROTTLED CLOSED TO 70% FLOW. BASED ON THIS CAN WE SAVE YOU $MONEY$
