How this estimate works
Variable-speed pumps draw different power at different speeds. Enter average measured wattage.
- Use your equipment data. Check a label, specification sheet, controller, or energy meter.
- Enter your utility rate. A recent bill is more useful than a national average.
- Test different schedules. Change one input at a time to compare scenarios.
Ways to reduce or refine the cost
1
Use the shortest schedule that maintains water quality.
2
Run variable-speed pumps at lower speeds when appropriate.
3
Keep baskets and filters maintained.
Transparent methodology
Results use the values you enter and standard energy formulas. They are planning estimates, not bills or guarantees.
Frequently asked questions
How many hours should a pool pump run?+
Climate, pool volume, equipment, and sanitation requirements determine the schedule.
How do I estimate variable-speed wattage?+
Use pump controller data or a compatible energy meter.
Does this include a pool heater?+
No. It calculates the circulation pump only.
