Is a pool pump expensive to run?

A variable-speed pump run longer at low speed filters the same water using a fraction of the energy of a single-speed pump. At typical use it adds about $44.11 to a monthly electric bill at the US-average rate, but that swings from $30.81 in the cheapest states to $114.72 in the most expensive.

How many watts does a pool pump use?

Pool Pump typically draws about 1,100 running watts. Because it has a motor or compressor, it briefly spikes to around 2,400 watts at startup, which matters for generator and breaker sizing but not for energy cost. Check the nameplate or label on your specific unit for its exact rating.

How much electricity (kWh) does a pool pump use?

At typical use (1,100 W for 8 hours a day), a pool pump uses about 8.8 kWh per day — roughly 268 kWh per month, or about 31% of what the average US home uses in a month (863 kWh). Energy used doesn't depend on your electricity rate — only the bill does.

How can I lower the cost of running a pool pump?

A variable-speed pump run longer at low speed filters the same water using a fraction of the energy of a single-speed pump. You can also cut the cost by lowering your electricity rate — many utilities offer cheaper off-peak hours — or simply by running it fewer hours. The calculator on this page shows how changing hours per day or your electricity rate moves the number.

How Much Does It Cost to Run a Pool Pump?

A pool pump runs for many hours a day all season, making it one of the largest single contributors to a summer electric bill. At the US-average rate of 16.5¢/kWh, running a pool pump costs about $44.11/month ($529.34/year) at typical use. Adjust the watts, hours, and your rate below for your exact number.

How much electricity does a pool pump use?

At 1,100 W for 8 hours a day, a pool pump uses about 8.8 kWh per day — roughly 268 kWh per month and 3,212 kWh per year. That's about 31% of the 863 kWh the average US home uses in a month. Energy use is the same everywhere — only the price per kWh changes your bill.

Measure what a pool pump really costs you

The estimate above uses typical wattage and hours. This load is usually hardwired or on a 240 V circuit, so a plug-in meter won't fit it; a whole-home monitor's sensors clip onto the circuit's wires inside the panel and log its real kilowatt-hours. That means working in a live panel — hire an electrician if that isn't you.
