Typical well pump wattage ranges from 500 to 2,000 watts, depending on the pump type and how deep your well is

A submersible pump — the most common type for residential wells — usually draws between 500 and 1,500 watts while running. A jet pump, which sits above ground, typically uses 750 to 2,000 watts. The actual number depends on three things: how far down the pump has to push water, how much pressure your household needs, and the pump's horsepower rating.

If your well is shallow (under 25 feet), a smaller pump may use only 500 to 750 watts. If it is deep (over 100 feet) or your home has multiple bathrooms and high water demand, the pump could run at 1,500 to 2,000 watts or higher. The pump does not run constantly — it cycles on when water pressure drops and off when the pressure tank fills — so your actual monthly electricity cost depends on how often it cycles.

Key Takeaways

  • Submersible pumps typically use 500 to 1,500 watts; jet pumps use 750 to 2,000 watts, with deeper wells requiring more power.
  • Your pump's horsepower rating, printed on the motor housing or in your well documentation, directly determines wattage — roughly 750 watts per horsepower.
  • The pump cycles on and off based on water pressure, so it does not run 24 hours a day; a typical household cycle is 2 to 4 times per day.
  • Monthly electricity cost for a well pump ranges from $15 to $50 for most households, depending on local rates and how often the pump runs.

How to find your pump's actual wattage

The easiest way is to look at the pump motor itself. If your pump is submersible, you may need to pull the well cap or check your well documentation, but the nameplate should list horsepower and voltage. A 1-horsepower pump at 240 volts draws roughly 750 to 900 watts. A 1.5-horsepower pump draws about 1,100 to 1,300 watts. A 2-horsepower pump uses 1,500 to 1,800 watts.

If you cannot find the nameplate, ask your well contractor or check your well permit paperwork — most municipalities keep a record of the pump size installed. You can also call a local well service company with your well location; they often have installation records on file.

Why depth and pressure matter

A pump that lifts water 30 feet uses far less energy than one that lifts it 200 feet. The deeper the well, the more work the motor does, and the larger the pump needs to be. Similarly, if your home has a large pressure tank and low water demand, the pump cycles less often and uses less total electricity. If you have high demand — multiple showers running, a washing machine, and outdoor watering — the pump cycles more frequently.

Pressure tank size also affects cycling. A larger tank (typically 40 to 80 gallons for residential wells) means the pump runs less often because it has more stored water to draw from before pressure drops and the pump kicks back on. A smaller tank forces more frequent cycling and higher monthly electricity use.

Estimating your monthly electricity cost

To calculate rough monthly cost, multiply your pump's wattage by the hours it runs per month, then divide by 1,000 to get kilowatt-hours. Multiply that by your local electricity rate (usually $0.10 to $0.15 per kilowatt-hour, though it varies by region).

For example: a 1,000-watt pump running 4 hours per day uses 4 kilowatt-hours daily, or about 120 kilowatt-hours per month. At $0.12 per kilowatt-hour, that is roughly $14 per month. A 1,500-watt pump running 6 hours per day would cost about $27 per month. Most households fall between $15 and $50 monthly, depending on well depth, pump size, and local electricity rates.

When a pump uses more power than expected

If your electric bill spiked and your pump seems to be running more often, the pressure tank may have lost its air charge — a common problem that forces the pump to cycle constantly. A waterlogged tank can also cause the pump to short-cycle (turn on and off rapidly), wasting energy. A well service technician can check the tank pressure and recharge it if needed, usually for $100 to $300.

A failing check valve or a slow leak in the pressure tank itself can also cause constant cycling. If the pump runs for hours without stopping, or if you hear it cycling every few minutes, have the system inspected before the motor burns out. Replacing a pump is far more expensive than fixing a tank or valve.

Comparing pump types and efficiency

Submersible pumps are generally more efficient than jet pumps because they sit directly in the water and do not have to fight air pressure to draw water up. A submersible pump rated at 1 horsepower will use less total electricity over time than a jet pump of the same horsepower, especially in deeper wells.

Newer pumps with variable-frequency drives (VFDs) can reduce energy use by 20 to 40 percent compared to standard fixed-speed pumps, because they adjust motor speed based on actual water demand rather than running at full power every time they cycle. If you are replacing an old pump, a VFD-equipped model costs more upfront but may pay for itself in lower electricity bills over 5 to 10 years.

What affects pump runtime throughout the year

Well pump cycling varies by season. In winter, when household water use typically drops, the pump runs less and uses less electricity. In summer, especially if you water a lawn or garden, the pump cycles more often and your bill rises. Drought conditions can also increase cycling because the water table drops and the pump has to work harder to reach the water.

If you notice your pump running much more in summer than winter, that is normal. If it suddenly runs constantly year-round, or if winter usage does not drop, the tank or check valve likely needs service.

Frequently Asked Questions

How many hours per day does a well pump typically run?

Most residential well pumps run 2 to 4 hours per day on average, though this varies widely based on household size, water use, and well depth. A family of four in a home with a 40-gallon pressure tank might see 3 to 5 hours of runtime daily. Homes with larger tanks or lower water demand may see only 1 to 2 hours.

Does a well pump use more electricity than a municipal water pump?

A well pump uses electricity only when it runs; municipal water is pumped at the treatment plant and delivered through pipes, so you pay for it through your water bill rather than as a separate electric charge. Well pump electricity cost is typically lower than a municipal water bill for the same household, but it depends on local rates and your water usage.

Can I reduce my well pump's electricity use?

Yes. Fix any leaks in your plumbing, install low-flow showerheads and faucet aerators to reduce water demand, and have your pressure tank and check valve inspected annually. If your pump is over 15 years old, replacing it with a newer, more efficient model can cut electricity use by 15 to 30 percent.

What size breaker or electrical panel capacity do I need for a well pump?

A 1-horsepower submersible pump typically needs a 20-amp breaker at 240 volts. A 1.5-horsepower pump needs 30 amps. A 2-horsepower pump needs 40 amps. Your electrician or well contractor can confirm the correct breaker size based on your pump's nameplate amperage rating, which is usually 10 to 20 percent higher than running wattage to account for startup surge.

Why does my pump use more power in winter when I use less water?

If your pump is running more in winter, the issue is usually not water demand but a failing pressure tank or check valve. A waterlogged tank or leaking valve allows pressure to drop faster, forcing the pump to cycle more often even though you are using less water. Have the system inspected by a well service technician.
