In some cases, energy savings can be significant enough to offset the initial investment within a few years.
Calculating Return on Investment (ROI)
Calculating the ROI for insulated siding involves comparing the initial investment to the long-term savings. The formula is as follows:
ROI = (Total Savings – Total Cost) / Total Cost * 100%
To illustrate, consider a homeowner who invests $10,000 in insulated siding. Assume their annual energy savings are $1,000. Over ten years, their total savings would be $10,000.
ROI = ($10,000 – $10,000) / $10,000 * 100% = 0%
In this example, the ROI is 0%, meaning the homeowner recouped their investment over ten years. However, if their annual savings were $1,500, the ROI would be positive:
ROI = ($15,000 – $10,000) / $10,000 * 100% = 50%
This indicates a strong return on investment. It’s crucial to obtain accurate estimates of energy savings, possibly through energy audits or consultations with energy efficiency professionals, to make a realistic ROI calculation.
