watts x hours per day of operation ÷ 1000 x cost per kilowatt hour
To get the cost of the kilowatt per hour look at your electricity bill.
-------------------------------------------------------------------------------------------------------------------------
This is what i got
120 X 24 = 2880
2880 ÷ 1000 = 2.88
2.88 X .11 = 0.3168 <---So thats about .31 cents a day to run a 120 watt pump.
$.31 X 30 days = $9.30<---Cost to run a month.
$9.30 X 12 months = $111.60 <---Cost yo run a year.
-------------------------------------------------------------------------------------------------------------------------
If you want to know how much it will cost a month multiply how many cents you pay per hour by 30 days and if you want to find out how much it cost to run a year multiply what you pay a month by 12.
Hope this is helpful info.
