61320 watts === 61.320 kilowatts per year
61.320 kilowatts x $0.15 per kw = $9.20 per year (if on 24 hours)
Same math for 12 hours = $4.60 per year
I use $0.15 per kw because I also include base fees and other fees. Take total bill and divide by total kw for that number.

Here is my calculation:
7 watts/1000 x $0.089879/kwh x 12 hours/day x 365 days = $2.75
According to the Leesburg Electric Company, this is the total additional cost to my bill for using a 7 watt light bulb. So, I don't see any reason to add the fixed costs that are applied to every bill regardless of your consumption.
