The exact figures will depend on factors mentioned above, such as energy prices and climate.
Return on Investment Calculation
Calculating the return on investment (ROI) for insulated siding involves comparing the initial cost increase against the cumulative energy savings over a defined period. A simple formula to estimate ROI is:
ROI = (Cumulative Energy Savings – Initial Cost Increase) / Initial Cost Increase * 100%
For example, if the initial cost increase is $5,000 and the cumulative energy savings over 10 years are $7,000, the ROI would be:
ROI = ($7,000 – $5,000) / $5,000 * 100% = 40%
This indicates a 40% return on the initial investment over 10 years. It is important to note that this is a simplified calculation and doesn’t account for factors like potential increases in energy prices or changes in the home’s value due to the improved energy efficiency. More detailed ROI calculations might incorporate these variables for a more precise estimate.
