How many watts does a well pump use?
A well pump uses 750–2,500 W (about 1,500 W on average). Running 2 hours/day, that is about 3.00 kWh a day and 90.0 kWh a month — roughly $16.48 a month at the U.S. average rate of 18.31 ¢/kWh.
This is the well pump electricity usage reference: watts, amps on a 240 V circuit, the kWh math, and links to what that usage costs in each state.
Watts, amps, and kWh for a well pump
| Measure | Value |
|---|---|
| Rated wattage range | 750–2,500 W |
| Average draw used in our math | 1,500 W |
| Amps at 240 V | 3.1–10 A (6.3 A at the average draw) |
| kWh per hour | 1.50 kWh |
| kWh per day at 2 hours/day | 3.00 kWh |
| kWh per month | 90.0 kWh |
| Cost per month at the U.S. average (18.31 ¢/kWh) | $16.48 |
The math is kWh = watts × hours ÷ 1000 and amps = watts ÷ volts. A well pump is normally wired for 240 V in US homes; a 120 V unit of the same wattage would draw twice the amps. For the dollars in your state, open cost to run a well pump in Texas and switch states from there.

Frequently asked questions
How many watts does a well pump use?
A well pump uses 750–2,500 W (about 1,500 W on average). Our usage and cost math uses 1,500 watts running 2 hours/day.
How many amps does a well pump draw?
On a 240 V circuit, 750–2,500 W works out to about 3.1–10 A; at the 1,500 W we use in the math that is 6.3 A.
How much electricity does a well pump use per month?
About 90.0 kWh a month at 2 hours/day. Lighter use (1 hours/day) comes to roughly 45.0 kWh and heavier use (4 hours/day) roughly 180.0 kWh.
How much does it cost to run a well pump?
About $16.48 a month at the U.S. average rate of 18.31 ¢/kWh — from roughly $11.45 in Louisiana to $43.20 in Hawaii at the same usage. The state cost-to-run pages price it at every state's rate.
