Pool Pump Electricity Cost Calculator

Pool pumps are one of the largest energy consumers for homeowners with pools. This calculator estimates how much it costs to run your pool pump based on its horsepower, daily run time, and electricity rate.

Pump Horsepower (HP)

Typical pool pumps are 0.75-2.5 HP

Hours Per Day

Recommended: 8-12 hours for full turnover

Electricity Rate ($/kWh)

Your electricity rate per kWh

Days Per Month

Days the pump runs per month

How to Use

1 Find your pool pump's horsepower rating on the label or in the manual.

2 Determine how many hours per day you run the pump.

3 Enter your electricity rate from your utility bill.

4 Set how many days per month the pump operates.

5 The calculator shows daily, monthly, and yearly operating costs.

Formula

Watts horsepower × 746

Daily Kwh watts × hours_per_day ÷ 1000

Daily Cost daily_kwh × price_per_kwh

Monthly Cost daily_cost × days_per_month

Yearly Cost monthly_cost × 12

Standard 1.5 HP Pool Pump

A 1.5 HP pump running 8 hours/day at $0.12/kWh uses about 8.95 kWh daily and costs $1.07/day, $32.22/month, or $386.64/year.

Why It Matters

Pool pumps can account for up to 30% of a pool owner's electricity bill. A variable-speed pump running at lower speeds can cut energy use by 50-80%, potentially saving hundreds of dollars annually.

Who Uses This Calculator?

• Homeowners and renters estimating electricity costs, appliance usage, solar savings, or EV charging expenses.
• Solar shoppers, EV owners, and households comparing energy upgrades before requesting quotes or changing usage habits.
• Anyone who wants a quick estimate of home energy costs using clear assumptions.

Frequently Asked Questions

How many hours should I run my pool pump?

Most pools need 8-12 hours of pump operation daily to circulate all the water once. In summer, aim for 10-12 hours; in winter, 4-6 hours may suffice.

Are variable-speed pool pumps worth it?

Yes. Variable-speed pumps can save 50-80% on energy costs compared to single-speed pumps. While they cost more upfront, they typically pay for themselves within 1-2 years.

Should I run my pool pump at night?

If you have time-of-use electricity rates, running at night during off-peak hours can save 30-50%. Otherwise, timing doesn't affect cost.

How much does a bigger pool pump cost to run?

Each additional HP adds about 746W of power consumption. A 2 HP pump costs about 33% more to run than a 1.5 HP pump for the same duration.
