formula for pump cost per month
 
The cost of operation of the pump is calculated by taking the wattage of the
pump times 24 hours per day and dividing by 1000 to get it into
kilowatts-hour, and then multiplying the result by the kilowatt-hour cost of
your electric company, which should be shown on your statement. For my
sequence pumps at 393 watts X 24hours / 1000watts per kilowatt = 9.43
kilowatt hours per day. 9.43 kilowatt hours X 4.1cents per kilowatt hour =
38.67 cents per day per pump.

Watts[amps x volts] divided by 1000 x kwh cost x 24 hours x 30 days= COST
I know my pump costs $5/month from April-October=$35.
