Selecting the Proper Pump

Step 4: Calculating Operation Expenses

You can determine the operating cost of any pump by using this formula: amps x volts divided by 1000 x KWH cost x 24 hours-a-day x 30.4 days-per-month = cost per month.

If the pump is rated in watts instead of amps use this formula: watts divided by 1000 x kWh x 24 hours-a-day x 30.4 days-per-month.

KWH is the kilowatt-hour cost, which you can get from an electric bill or by calling your local electric company.
