Pool Pump Energy Cost Calculator
Estimate electricity used by pool circulation equipment and compare schedules or pump settings using the real measured input wattage.
How to use this calculator
- Enter the pump electrical input (w) using the units shown beside the field.
- Enter the operating hours per day using the units shown beside the field.
- Enter the days in period using the units shown beside the field.
- Review the calculated values and check that the assumptions match your scenario.
- Change one input at a time when comparing scenarios so you can see which assumption drives the result.
Formula and assumptions
Energy = input watts × operating hours × days / 1,000; cost = energy × price per kWh.
- Do not reduce essential filtration or sanitation below manufacturer or local health guidance just to reduce the estimate. Variable-speed pumps draw changing power.
- The result is computed from the values you provide; it does not fetch external rates, live account data or local rules.
Worked examples
Worked example
An 850 W pump running seven hours per day for 30 days uses 178.5 kWh.
Example inputs: Pump electrical input (W) = 850, Operating hours per day = 7, Days in period = 30, Electricity price per kWh = 0.29.
Compare the displayed output with your own measurements before using it in a decision.
Understanding the result
Do not reduce essential filtration or sanitation below manufacturer or local health guidance just to reduce the estimate. Variable-speed pumps draw changing power.
Results are estimates based on the stated model. If the situation depends on measured conditions or contractual specifications, use those source values rather than typical assumptions.
Important notes
Do not reduce essential filtration or sanitation below manufacturer or local health guidance just to reduce the estimate. Variable-speed pumps draw changing power.
Frequently asked questions
What formula does this calculator use?
It uses the method described above: Energy = input watts × operating hours × days / 1,000; cost = energy × price per kWh.
What should I verify before relying on the result?
Do not reduce essential filtration or sanitation below manufacturer or local health guidance just to reduce the estimate. Variable-speed pumps draw changing power.
Can I compare different scenarios?
Yes. Change the inputs while keeping units and definitions consistent, and record the assumptions used for each scenario.
