Operating Costs

We know that you have had your eye on that fine looking Tancho Sanke from Laguna Koi Ponds. You could buy it if only your electric bill was just a little lower. Here is the formula to determine your pumps monthly energy cost.

Look on your pump and find the rated volts and amps. Use the numbers printed on the pump. The exact voltage in your house does not matter because the electric company charges you by kilowatt hour.

  1. Multiply the Volts times the Amps to get Watts.VxA=W
  2. Divide the Watts by 1000 to get Kilowatt hours. W/1000=KWH
  3. Multiply Kilowatt hours times 720* to get kWh used a month.KWHx720=KWHM
  4. Multiply KWHM times $** per Kilowatt hour= Monthly cost. KWHMx$=Monthly cost.


  • 24 hours times 30 days in one month=720 hours
  • Look on your electric bill to find the charge per kilowatt hour.

Notice that the energy cost is the same to operate a pump on 110 volts AC as 220 volts AC.
