Return on Investment (ROI) Calculation for Insulated Siding
Calculating the ROI for insulated siding involves comparing the initial investment with the cumulative savings over the siding’s lifespan. A simplified formula can be used:
ROI = (Total Savings – Initial Investment) / Initial Investment * 100%
For example, consider a home requiring 1000 square feet of siding. If insulated vinyl siding costs $9 per square foot for materials and installation ($9000 total), and it results in annual energy savings of $300, over a 20-year period, the total savings would be $6000. Using the formula:
ROI = ($6000 – $9000) / $9000 * 100% = -33.33%
In this example, the initial investment exceeds the savings over 20 years, resulting in a negative ROI. However, this is a simplified calculation. Factors such as increased home value, reduced maintenance, and longer lifespan can significantly impact the overall ROI. A more accurate calculation would incorporate these additional factors. Furthermore, a higher energy savings percentage or a longer lifespan for the siding could easily result in a positive ROI.
