Calculating the Power Consumption of a Pump

Pump Terminology

Wattage- Wattage measures the power of a pump.  The cost of operating a pump with a specific wattage can be measured as follows:

Total monthly cost of operating a pump continuously = cost per kilowatt hour * 30 days in a month* 24 hours in a day * pump wattage / 1000

Example

Let's assume that your pump runs at 90 W and it costs you $0.07 per kW/h from your utility company.

Total monthly cost of operating pump = $0.07 kW/h * 30 days/month * 24 hours/day * 90 W / 1000 = $4.54.

Therefore, it would cost $4.54 per month to operate this pump continuously.
