Pump watts
Horsepower labels are not the bill. Use watts or measured power when possible.
Pool pump cost
Estimate how much a pool pump adds to the electric bill.
Pool pumps can become a major electricity load because they run for many hours. The real cost depends on watts, speed, timer schedule, season, and electricity rate.
Quick estimates
Efficient schedule
750 W x 4 h/day$15-$31/mo
Lower wattage or shorter runtime can keep pool electricity modest.
Common schedule
1,100 W x 8 h/day$45-$90/mo
A typical long daily schedule that is worth checking in summer.
Heavy runtime
1,500 W x 12 h/day$92-$184/mo
Possible with single-speed pumps, long filtration windows, or high rates.
Timer hours
An extra four hours per day can add a noticeable amount over a month.
Speed setting
Variable-speed pumps can reduce power draw when lower speeds are appropriate.
Pool season
Summer filtration, cleaning, and water features can change pump runtime.
Cost formula
Pool pump cost = pump watts / 1,000 x daily hours x rate.
A 1,100 watt pump running 8 hours per day uses 8.8 kWh per day. At 17 cents per kWh, that is about $45 for 30 days before fixed charges.
If the bill is high, compare the pump schedule with AC runtime because both often rise during the same summer months.

How much does a pool pump cost to run per month?
A pool pump can add roughly $30 to $150 or more per month depending on watts, hours per day, electricity rate, pump speed, and season.
Why is my pool pump electricity cost high?
Long runtime is the usual driver. Single-speed pumps running many hours per day can use far more electricity than expected.
How can I lower pool pump electricity cost?
Review timer hours, speed settings, filtration needs, maintenance, and whether a variable-speed pump or better schedule would reduce kWh.
