Why the cost differs in Ohio
Ohio has the 35th cheapest residential electricity of the 50 US states and Washington, DC we track, at 19.38¢ per kWh against a national average of 18.16¢. That is +6.7% compared with the national figure. Ohio has a competitive retail market, so households can shop for supply and published averages blend many different contracted rates. PJM capacity costs are the main upward pressure on bills rather than fuel. The climate delivers a genuine dual peak, with cold winters and humid summers both contributing substantially to annual consumption.
For this appliance specifically, the difference works out to an extra $53.44 a year over what the same pool pump would cost at the national average rate. Run the identical appliance in Hawaii and it would cost $2,066 a year; in Nevada it would cost $557. That spread of $1,509 is entirely down to location.
Reducing use by 100 kWh would save $19.38 in energy charges at Ohio's average rate, compared with $18.16 at the US average. Whether a replacement appliance pays for itself also depends on its purchase price and the energy it actually saves.
Use the energy and delivery price that applies to your own utility plan in Ohio. If your plan has time-of-use prices, calculate each period separately or use a rate weighted by the electricity used in each period. Fixed monthly fees are outside this appliance energy-cost estimate.

About running a pool pump
Pool-pump electricity cost depends on input watts at each operating setting and the time spent there. Add the energy for separate speed periods, or use a dedicated kWh reading. Motor horsepower, RPM and a maximum wattage do not establish your daily consumption.
How we worked this out
The arithmetic is simple and we would rather show it than hide it. Divide watts by 1,000 to get kilowatts, multiply by hours of use and by the duty cycle to get kilowatt-hours, then multiply by your rate:
1500W ÷ 1000 × 8h = 12.000 kWh/day × 19.38¢ = $2.326 per day
One honest caveat: Ohio’s figure is a state average published by the EIA. Your own utility’s tariff, any time-of-use pricing, fixed monthly service charges and local taxes all shift the real number. Put your actual per-kWh rate into the calculator above for a figure that reflects your bill.
How to estimate your pool pump electricity use
For a variable-speed pool pump, calculate watts × hours ÷ 1,000 for each part of the day and add the kWh. Multiply that total by your price in dollars per kWh. Use power readings that belong to each operating period; a maximum rating applied to the whole day can misrepresent the schedule.
Add up a variable-speed pump schedule
- Find electrical input watts for each operating setting in your exact model documentation, an existing pump display or a suitable energy monitor. Check whether the display reports estimated watts or measured input power. RPM, a speed percentage and gallons per minute are different quantities; do not enter them as watts.
- Record the average input watts and actual hours for each non-overlapping part of one representative use day. Convert minutes to hours by dividing by 60. Include priming, cleaning or other pump operation when it adds energy outside the periods already counted. The time blocks for this one pump must not overlap or exceed 24 hours together.
- Open the multiple-appliance planner linked below. Use one row per operating period, Quantity 1, its Average input power and its Time used. Add a load for the next period, then enter your electricity price in cents per kWh and the exact number of days that this same daily schedule repeats. A second row describes another period for the same pump, not a second pump.
- If you have dedicated pump-system kWh instead, choose Metered energy in the calculator above. Enter the difference between cumulative start and end readings and all elapsed measurement days. That energy already includes the operation inside its boundary; do not add the same speed periods again. For one steady operating period, Watts and hours with its actual running hours and 100% duty also works.
| Item | Example |
|---|---|
| Period A: quantity 1, 300W, 6 hours | 300 × 6 ÷ 1,000 = 1.8 kWh per day |
| Period B: quantity 1, 1,000W, 2 other hours | 1,000 × 2 ÷ 1,000 = 2 kWh per day |
| Combined energy | 1.8 + 2 = 3.8 kWh per day |
| Electricity price: 20 cents/kWh | 3.8 × $0.20 = $0.76 per day |
| Repeat that schedule for exactly 30 days | 114 kWh and $22.80 |
| Repeat that schedule for 150 use days | 570 kWh and $114.00 |
These are invented inputs for two periods of one pump, not manufacturer measurements, recommended speeds or a filtration schedule. They show only the energy in those eight hours; other operation or standby needs its own accounting. The planner uses exact repeat-days. The reference tables and watts-and-hours calculator on this page instead show a 30.44-use-day monthly equivalent, which would be $23.13 at this example daily cost.
Reading pump data and comparing schedules
This estimates electricity cost. It does not determine required filtration hours, sanitation, flow, freeze protection or a suitable pump size. Follow your pool and equipment requirements when assessing schedules. Purchase, installation, maintenance and fixed utility charges are separate.
- Check the units and wording on your model. The Pentair IntelliFlo3/IntelliPro3 user guide calls its dashboard Run Data estimates; its illustrated display labels power as Est. Power (watts). That is an operating estimate, not a cumulative kWh reading or a documented revenue-grade meter. The same guide distinguishes scheduled, timer and manual programmes.
- Horsepower is not electrical input. About 746 watts is the mechanical equivalent of 1 HP; actual input depends on load and efficiency. Likewise, a single RPM does not imply one universal wattage across different pumps, plumbing, filters and operating conditions.
- Compare complete schedules that meet the same pool and equipment needs. Pentair's savings calculator uses specified test-curve and runtime assumptions and says actual performance depends on the installation. Its modelled percentage saving is not a promise for your pool.
- Use actual season days. If cleaning days, summer use and winter operation have different daily schedules, calculate those periods separately and add their costs. The planner repeats every entered row for the same number of days.
- Count a heater, salt chlorinator, booster pump or lights separately only when their energy is outside your pump reading. A single electricity price also cannot reproduce a tariff with different prices at different times.
Calculation and data sources
Daily kWh = watts ÷ 1,000 × hours × duty cycle ÷ 100. Multiply kWh by your rate in dollars per kWh to get cost. The wattage, hours and duty cycle above are editable example assumptions, not EIA measurements of this appliance.

Questions about pool pump running costs
How much electricity does a pool pump use?
In this example, 1500 watts at a 100% duty cycle uses 1.500 kWh per scheduled hour. At 8.00 hours per day, that is 12.000 kWh per use day. Your model and operating conditions can differ.
How much does it cost to run a pool pump for an hour?
The default example costs $0.291 per scheduled hour at the Ohio average of 19.38¢/kWh for August 2026. This includes the selected duty cycle. Enter your watts, duty cycle and electricity price for your own estimate.
Does the annual cost assume I use it every day?
The reference tables use 365 days at the displayed single-power schedule; monthly figures use 30.44 use days. For a seasonal pool, enter actual use-days in watts-and-hours mode. For several daily speed periods, the linked planner adds separate power-and-time rows and repeats every row for the exact number of days entered. Calculate different seasonal schedules separately.
Why does electricity running cost vary by state?
For August 2026, the EIA state averages range from 12.72¢/kWh in Nevada to 47.18¢/kWh in Hawaii. Equal electricity use costs more at a higher rate. Your utility tariff can differ from the state average.
How do I calculate a variable-speed pool pump's monthly cost?
Add watts × hours ÷ 1,000 for each non-overlapping operating period, then multiply the combined kWh by your electricity price and the number of days. With illustrative inputs of 300W for 6 hours and 1,000W for 2 other hours, the total is 3.8 kWh/day. At $0.20/kWh that is $22.80 for exactly 30 repeated days in the planner, or $23.13 per 30.44 use days. These are examples, not typical pump readings.
How many watts does a 1 HP pool pump use?
The horsepower rating alone cannot establish actual electrical input. About 746 watts is the mechanical output equivalent of 1 HP, not a measured electrical draw. Use input watts for your model at its operating conditions or a dedicated input-energy reading.
Can I work out electricity use from pump RPM or flow?
Not from that number alone. Model, load, plumbing and other system conditions affect power. Read electrical watts at the relevant operating setting and pair them with its time, or use recorded kWh. A flow or speed display is not automatically an energy meter.
Does a variable-speed pump guarantee a fixed percentage saving?
No. Compare total input energy for complete schedules that meet the same pool and equipment requirements. Lower power over a longer time changes the result, and vendor savings figures depend on their stated comparison assumptions. Reprice both schedules using the applicable tariff.
How many hours should I run my pool pump?
This cost calculator does not prescribe filtration or sanitation hours. Your pool conditions and equipment requirements determine the schedule. Enter that schedule and its power readings to estimate cost; include additional cleaning, priming or seasonal operation without double counting time.
