Pool Pump Running Cost Calculator
Pool pumps can be a home's largest seasonal load. Flow, plumbing resistance, speed and filtration schedule affect runtime.
Direct answer: The editable 1,500 W pump preset costs about $2.21 per 8-hour day and $66.38 per 30-day month at the U.S. average rate. Enter watts measured at the actual programmed speed.

Calculate and compare
Results update as you type.
kW × effective runtime × rate. Effective runtime = hours/day × duty cycle.
Baseline vs scenario
Compare two annual energy-use estimates.
Old vs new appliance payback
Use annual kWh for both models. Leave rebate at $0 unless you have a confirmed amount.
Simple payback = net upfront cost ÷ annual electricity-cost savings. Excludes financing, maintenance, rate changes and time value of money.

Compare 4, 8, or 12 hours per day
These illustrative scenarios use the 1,500 W preset at 100% duty. Variable-speed pump power can differ substantially by programmed speed, flow, and plumbing resistance.
| Daily schedule | Daily energy | Daily cost | Monthly cost |
|---|---|---|---|
| 4 hours | 6.00 kWh | $1.11 | $33.19 |
| 8 hours | 12.00 kWh | $2.21 | $66.38 |
| 12 hours | 18.00 kWh | $3.32 | $99.58 |
Use actual watts at the programmed speed rather than horsepower alone. Follow pool sanitation, turnover, manufacturer, and local guidance before changing filtration schedules.
Pool pump cost quick answers
How much does a pool pump cost per day?
The current 8-hour preset costs about $2.21 per day. Your measured watts, runtime, and rate determine the result.
How much does a pool pump cost per month?
The same 8-hour example is about $66.38 per 30-day month.
Does variable speed reduce electricity use?
Lower programmed speeds often draw less power, but measure actual watts and preserve required filtration and sanitation.
Should I estimate from horsepower?
Actual electrical watts at the programmed operating point are a better cost input than horsepower alone.

Make the estimate more accurate
- Measure watts at the actual programmed speed.
- Lower speeds often use much less power.
- Follow sanitation and equipment guidance when changing schedules.
Presets are estimates. Use your model label, an EnergyGuide annual-kWh figure or a safe meter reading when available. Compare old and new appliance payback.
