Energy rate (electricity cost)
The average residential price of electricity in the U.S. in 2015 was 12.66¢/kWh.
To find the price per kWh (Kilo Watt hour) for your state and sector, check your energy bill or go to the EIA website.

No. of times an old fixture to be replaced each year 3.50 times per year -
No. of times an old fixture to be replaced during the LED fixture's lifespan
(11 years 4 months 30 days)		 40 times -
Cost of replacements each year
([Incand. bulb cost] X [Number of replacement per year]) 		$3.50 per year -
Total annual cost
([Cost of replacing fixtures] + [Electricity] + [Labor cost]) 		$44.90 per year $4.97 per year
(same as the annual electricity cost)
Total cost
(after 11 years 4 months 30 days)		 $513 $106
Total savings /w LED fixture (ROI)
(after 11 years 4 months 30 days)		 $513 - $106 = $407
