Well pump: electricity cost calculator
Quick answer: a typical well pump costs about $11/month while in use at the U.S. average electricity price (18.34¢/kWh) — about $134 per year. Your number depends on wattage, runtime and your state — calculate it below.
Submersible well pumps draw 750 W (½ HP) to 2,200 W (2 HP) while running. Two hours of total daily runtime is typical for a household; irrigation multiplies it quickly.
2.00 kWh/day used · 61 kWh/month in use · 731 kWh/year at 18.34¢ per kWh

|---|---|---|---|
| Light use | 750 W | 1.2 h | $5.02 |
| Typical | 1,000 W | 2.0 h | $11.16 |
| Heavy use | 2,200 W | 3.0 h | $36.84 |
Common questions
Why did my well pump's cost suddenly jump?
Short-cycling is the usual culprit — a waterlogged pressure tank or a leak makes the pump start dozens of extra times a day. Each start draws a large inrush current and wears the motor.

Methodology & sources
Cost = watts ÷ 1,000 × hours × price per kWh. Electricity prices are average residential prices by state from the EIA Electric Power Monthly, Table 5.6.A (June 2026). EIA averages include delivery charges and taxes but are not any specific utility tariff — for an exact figure, use the rate from your own bill. Wattage presets reflect common product ranges; check your appliance's nameplate or a plug-in power meter for its true draw.
