THE NUMBERS BEHIND THE TOOL

Method, not mystery.

Input watts × operating hours ÷ 1,000 = kilowatt-hours

Then multiply kilowatt-hours by your energy price. Seasonal schedules and multiple speeds are summed before annualization. Values are rounded for display only.

FAQsClick to expand and learn more about how the calculator works, your pool pump and the assumptions used.

How much electricity does my pool pump use?

Start with electrical input watts at the operating setting you actually use. Multiply that power by runtime to estimate energy use. The calculator accepts your values; it does not assume a typical pump wattage.

Evidence energy

How the calculator works

Each speed segment contributes watts × hours ÷ 1,000 kWh per operating day. The calculator adds the segments, then applies your days per week and active months. Headline daily and monthly figures are calendar-year averages, including off days; the schedule breakdown also shows operating-day figures.

Evidence energy

Horsepower, voltage and amperage

Horsepower is not a substitute for measured electrical input. Motor loading and efficiency affect consumption. Enter watts from suitable metering or manufacturer operating data; this tool deliberately does not convert horsepower alone into exact electrical demand.

Evidence horsepower

Why volts times amps is not used here

AC real power also depends on power factor. Voltage and amperage by themselves are not enough for this estimate. This tool does not ask you to measure live wiring.

Evidence electrical

Single-speed vs variable-speed pool pumps

Select the pump type and enter the power and runtime for each operating speed. Two-speed mode supports up to two segments; variable-speed mode supports more. These are your operating scenarios, not a recommended filtration schedule.

Evidence types

Why pump speed affects electricity consumption

The optional RPM model applies a cubic speed relationship only as an illustration. It assumes the same pump and impeller, little or no static head, and approximately unchanged efficiency. Measured electrical watts at each speed are preferable. Changing RPM does not prove equivalent circulation or guaranteed savings.

Evidence affinity

How electricity rates affect operating costs

The energy charge is kWh multiplied by your electricity price. Use your own applicable energy rate; the example $0.15/kWh is not a location-specific tariff. Fixed fees, taxes and demand charges are excluded. You can enter a different rate for each season.

Evidence cost

Worked calculation example

For the labelled example, 1,500 W × 8 hours ÷ 1,000 = 12 kWh per operating day. At $0.15/kWh that is $1.80. With daily operation all year, 365 days gives 4,380 kWh and $657 per year. These are arithmetic examples, not measured household costs.

Evidence energy
Assumptions and limitationsClick to expand to see the key assumptions, what the calculator does and does not include, and important limitations.
  • Estimates cover pump electricity only. They do not assess pool water quality, adequate filtration, equipment compatibility, or electrical installation.
  • Annualization uses 365 days and equal-length months (365/12). Seasonal months must not overlap; inactive months use zero energy.
  • The supported range is 0–10,000 W, 0–24 total hours/day and $0–10/kWh. These are software guardrails, not equipment ratings or typical values.
  • Do not reduce operating time solely because a lower number appears here. Follow the requirements for your equipment and pool operation.
  • Scenario B savings may be negative. Percentage change is unavailable when the baseline is zero. Modelled savings are not a performance guarantee.

Adjustable Speed Pumping Applications — Pumping Systems Tip Sheet 11

U.S. Department of Energy · For centrifugal pumping with little or no static head, the affinity relationship models power proportional to the cube of rotational speed.

Illustrative model only: same pump/impeller and fluid, friction-dominated circuit, approximately unchanged efficiency. Actual motor/drive efficiency and system curve can invalidate electrical estimates; not a filtration-equivalence guarantee.

Pool Pumps

ENERGY STAR / U.S. Environmental Protection Agency · Single-speed operation uses one speed; multi-speed and variable-speed pumps allow different operating speeds to match a pool operation.

No generic savings percentages, dollar savings or recommended filtration hours are imported. Two-speed schedules use two user-entered power levels.

Calculator Guidance & Limitations

HomeA-Go calculators provide estimates for general guidance only. Actual energy use and costs vary with equipment, installation, operating conditions and utility rates.

Direct EPA operating test point rounded to nearest 10 W; no extrapolation. Use only as a starting estimate for the stated flow/head/RPM condition. Actual installation power may differ.

Not a recommendation for adequate filtration, sanitation, heater flow or equipment safety. Equal hours do not establish equal water circulation. Confirm settings with equipment instructions and actual power where available.

Comparison uses the hours, season and electricity rate entered independently for each scenario. Different test conditions need not provide equivalent circulation; a lower cost alone does not establish a suitable replacement. Estimates exclude unentered standby power.

Supported pump identification

Pump type comes from manufacturer identification. Suggested watts require an explicit documented operating condition. Actual user watts take priority; hours and rates remain user inputs. Availability and market share have not been established.
