Pool Pump Electricity Cost Calculator - Monthly Energy Use

Calculate exactly how much it costs to run your pool pump per month and year. Enter Horsepower or Watts to see energy usage and potential savings.

How to Lower Pool Energy Costs

The single most effective way to save money on your pool is to switch to a **Variable Speed Pump (VSP)**. Unlike single-speed pumps that run at 100% power all the time, VSPs can run at a low RPM, using up to 90% less electricity.

Pro Tip: Most pools only need to be "turned over" (all water filtered) once per day. Use this calculator to see how much you save by reducing runtime from 12 hours to 8 hours.

Actionable Steps

Understanding Watts vs Horsepower

While pumps are sold by Horsepower (HP), they pull Watts from your electrical panel. A 1.5 HP single-speed pump typically uses about 1500-1800 Watts. A 1 HP pump uses about 1200 Watts.

Pro Tip: Running your pump at night can save you money if your utility provider offers lower off-peak rates. Balance your pump schedule with your chemistry using our Baking Soda Alkalinity Tool for optimal water health.

Frequently Asked Questions

Is a Variable Speed Pump (VSP) worth it?

Absolutely. While the up-front cost is higher, a VSP can pay for itself in energy savings within 2 years. They are also much quieter than traditional pumps.

Should I run the pump while swimming?

Yes, it is generally better to keep the water circulating while the pool is in use to ensure that the chlorine is evenly distributed and the skimmer can catch debris.
