Return on Investment (ROI) Calculation
ROI is calculated as the net profit divided by the total investment. For the example above, let’s assume a five-year timeframe.
ROI = (Total Savings – Total Costs) / Total Investment
In this scenario, total savings over five years would be $250,000 ($50,000/year5 years). Total costs over five years, including operating costs, would be $330,000 ($310,000 initial investment + $20,000/year
5 years). Therefore
ROI = ($250,000 – $330,000) / $310,000 = -0.258 or -25.8%
This hypothetical example shows a negative ROI. However, different scenarios, such as higher savings due to increased efficiency or reduced initial investment, could result in a positive ROI. Detailed modeling with realistic data is crucial for accurate ROI projection.
Total Cost of Ownership (TCO) Comparison: Manual vs. Automated Systems
A TCO analysis compares the overall costs of manual and automated material handling systems over their lifespan.
