These are illustrative figures and will vary significantly depending on individual circumstances.
Calculating Return on Investment (ROI)
Calculating the ROI for insulated siding involves comparing the total cost of installation to the cumulative energy savings over a specific period. A simple formula for calculating ROI is:
ROI = (Total Energy Savings – Total Installation Cost) / Total Installation Cost * 100%
For instance, if the total installation cost is $10,000 and the estimated annual energy savings are $1,000, the ROI after 5 years would be: (($1,000/year * 5 years) – $10,000) / $10,000 * 100% = -50%. This indicates that the investment hasn’t yielded a positive return within five years. However, extending the timeframe to 10 years, assuming consistent energy savings, the calculation changes to: (($1,000/year * 10 years) – $10,000) / $10,000 * 100% = 0%. A positive ROI is achieved only after the cumulative energy savings exceed the initial investment. The timeframe to achieve a positive ROI will vary depending on factors such as the initial cost, energy savings, and climate.
Factors Affecting ROI
Several factors influence the ROI of insulated siding. These include the R-value of the siding, regional energy prices, the home’s existing insulation, and the climate.
