You can determine the operating cost of any pump by using this formula: amps x volts divided by 1000 x KWH cost x 24 hoursaday x 30.4 dayspermonth = cost per month.
If the pump is rated in watts instead of amps use this formula: watts divided by 1000 x kWh x 24 hoursaday x 30.4 dayspermonth.
KWH is the kilowatthour cost, which you can get from an electric bill or by calling your local electric company.
