How Much Does It Cost to Run a Well Pump in Missouri? (2026)
A submersible well pump draws 750 to 2,200 watts and runs whenever the pressure tank drops. A typical household uses 1 to 2 hours of pump time a day, making it a noticeable but modest load.
A typical well pump (1,100 W) costs $0.18 per hour, or about $8.03 per month at 1.5 hours a day in Missouri. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low 750 W | $0.12 | $0.18 | $5.47 | $66.60 |
| Typical 1,100 W | $0.18 | $0.27 | $8.03 | $97.68 |
| High 2,200 W | $0.36 | $0.54 | $16.06 | $195.37 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 1.5 h/day ≈ 602 kWh per year.
One hour of a well pump (1.1 kWh) is the same electricity as
- 6.1km in an electric car
- 11hours of TV
- 24hours of a laptop
- 122hours of an LED bulb
In Missouri, with electricity at 16.2¢ per kWh (source: EIA Table 5.6.A, 2026-06), a typical well pump costs $0.18 per hour and about $97.68 per year at 1.5 hours a day. That is about 12% less than the national average for the US ($9.08 per month), because electricity in Missouri costs 16.2¢ per kWh against 18.3¢ nationally. Each $1.00 of electricity buys roughly 5.6 hours of use.
How to lower the cost of running a well pump
- Fix leaks and dripping taps. Every litre wasted is pump time.
- Check the pressure tank. A waterlogged tank makes the pump short-cycle.
- Water the garden in the morning when pressure and efficiency are best.
