ROI = (Net Profit / Cost of Investment) x 100%
Where Net Profit is the total energy savings over the investment period minus the initial investment cost.
Example Calculation of ROI Over a 10-Year Period
Let’s consider a hypothetical scenario. Assume the initial cost of installing energy-efficient insulated siding on a 2,000 square foot house is $20,000. Assume that the improved insulation reduces annual heating and cooling costs by $1,500 in the first year. We will factor in a conservative 3% annual increase in energy costs.
| Year | Annual Energy Savings | Cumulative Energy Savings |
|---|---|---|
| 1 | $1,500 | $1,500 |
| 2 | $1,545 | $3,045 |
| 3 | $1,591.35 | $4,636.35 |
| 4 | $1,638.96 | $6,275.31 |
| 5 | $1,687.88 | $7,963.19 |
| 6 | $1,738.15 | $9,701.34 |
| 7 | $1,790 | $11,491.34 |
| 8 | $1,843.70 | $13,335.04 |
| 9 | $1,898.81 | $15,233.85 |
| 10 | $1,955.39 | $17,189.24 |
In this example, the cumulative energy savings over 10 years are $17,189.24. The net profit is $17,189.24 – $20,000 = -$2,810.76. Therefore, the ROI is (-$2,810.76 / $20,000) x 100% = -14.05%. This indicates a negative ROI in this specific scenario, suggesting the investment may not be financially beneficial in this particular case. However, this is a simplified example and actual ROI will vary greatly depending on individual circumstances and energy price fluctuations.
