Electricity use guide
How much does a sump pump cost to run?
Using a planning draw of 800 watts for 0.5 hours a day, this example uses 0.40 kWh daily. At the June 2026 U.S. residential average of $0.1834 per kWh, that is about $0.07 per day or $26.78 per year.
- Daily electricity
- 0.40 kWh
- Monthly cost
- $2.23
- Annual electricity
- 146.0 kWh
- Annual cost
- $26.78
Calculation for this example
800 W ÷ 1,000 × 0.5 hr/day × 365 days × $0.1834/kWh = $26.78/yearElectricity use in kilowatt-hours equals watts divided by 1,000, multiplied by runtime. Cost equals that energy use multiplied by the price per kWh.
What changes the actual cost?
- Timers, speed settings, standby draw, and seasonal schedules can materially change annual electricity use.
- A plug-in electricity meter can replace the planning wattage with a measured average for equipment that changes power levels.
