Cost to run a well pump
Big loads · typical wattage 1,000 W (750 W-2,000 W)
A well pump draws about 750 W-2,000 W (typically 1,000 W). Run 2 hours a day, it uses about 730 kWh/year, which costs roughly $11.29/month and $135/year at the US average residential rate of 18.56¢/kWh (March 2026). At a high-rate state like California (33.35¢) it costs more; at a low-rate state like Washington (14.40¢) it costs less.
