Weather Proofing Project ROI
For all of you ROI enthusiasts, I found the receipts, totaled the costs and ran a few numbers
Weather Proofing Project - Return on Investment $166.48 = total project materials cost 333.74 Therms = Oct '09 - April '10 natural gas usage 14.5% = 48.39 therms $1.0625/therm = average cost per therm for the past 4 years $51.41 estimated annual savings 3.24 year estimated payback Notes:
But, even with higher or lower natural gas prices and warmer or colder winters I should hit break-even in less than 4 years. Tim
