Watts x 24 hours ÷ 1000 kilowatts x kilowatt rate x days in the month.
or
Amps x Volts x 24 hours ÷ 1000 kilowatts x kilowatt rate x days in the month.
Example: HD-1800 pump
402.5 watts
402.5 x 24 ÷ 1000 x $.08 x 30 = $23.19 Monthly Operational Cost.
Example: HD-1800 pump
3.5 amp, 115 volt
3.5 x 115 x 24 ÷ 1000 x $.08 x 30 = $23.19 Monthly Operational Cost.
