If you're on a private well out in the country, you've probably wondered what that pump is quietly doing to your electric bill — there's no separate meter to tell you. The good news for most folks: for everyday household water, a well pump is usually one of the smaller lines on your bill. The catch is that a few specific situations can turn it into one of the biggest, and most of those are fixable.
The short answer
For ordinary household water use, a residential well pump in Texas usually costs only a few dollars a month to run. That's because it doesn't run around the clock — it kicks on in short bursts to refill your pressure tank when you use water, then shuts back off. Your cost rises with how much water you use and how deep your well is, and it can climb fast if you irrigate, fill a pool, water livestock, or have a leak that keeps the pump cycling. Use your own pump size and your own rate to pin down your number.
Why a Well Pump Costs Less Than Folks Expect
Most rural Texas homes run a submersible pump — a motor that sits down in the well and pushes water up to a pressure tank in the house or well house. Here's the part that surprises people: that pump is off most of the time. It only switches on when you open a tap, flush a toilet, or run the washer and the pressure tank drops below its cut-in point. Once the tank is topped back up, the pump shuts off again. So unlike an air conditioner that can run for hours in the Texas heat, your pump might only add up to a few minutes of runtime here and there across the day.
That's why the real question isn't "how big is my pump" so much as "how much water does my household use." Common residential well pumps run somewhere around one-half to one-and-a-half horsepower. As a rough rule, one horsepower is about three-quarters of a kilowatt of output, but a working pump usually pulls somewhere in the neighborhood of one to two kilowatts once you count motor losses. Deeper wells and larger homes lean toward the higher end.
A Rough Example, With Numbers You Can Swap Out
Let's walk through a simple illustration — and please treat every number here as an example, not a promise. Say your pump draws about 1 kilowatt while it's actually running. If all the taps, toilets, and appliances in your home together trigger it for a total of roughly one hour a day, that comes to about 30 kilowatt-hours over a month. At an example rate of 15 cents per kWh, that's somewhere around 4 to 5 dollars for the month.
That's genuinely modest — less than most people guess. But notice how much rides on those two inputs. A bigger or deeper-well pump, or a household that simply uses far more water, changes the picture quickly. To get a figure that actually fits your place, use your own pump's horsepower and your own electricity rate rather than these round numbers.
What Actually Drives the Cost
Four things move the needle on what your pump costs:
Well depth. The deeper the water sits, the more work the pump does to lift each gallon, so a deep well uses more energy per gallon than a shallow one. Total water used. Since the pump runs to replace water you've already used, a household watering a big lawn will always pay more than a careful two-person home. Pump efficiency and age. An older, oversized, or worn pump does the same job for more electricity. Short-cycling. If the pressure tank has lost its air charge or failed, the pump clicks on and off constantly instead of running in clean, longer stretches — wasteful, and hard on the motor.
The Uses That Quietly Balloon the Bill
For a normal indoor routine, the pump stays cheap. The cost climbs when the pump has to move a lot of water:
Irrigation and sprinklers are usually the biggest swing. Running zones for an hour or two on a timer several days a week can multiply your pump's runtime in a hurry — our guide on irrigation electricity cost digs into that load on its own. Filling or topping off a pool pulls a lot of water at once, and the pool's own pump is a separate cost worth understanding — see what a pool pump costs to run. Livestock and large gardens add steady demand, especially through a dry Texas summer. And leaks are the sneaky one: a running toilet or a cracked line out to the barn can keep the pump cycling all night for water nobody used, turning a few-dollar load into a real monthly expense.
A pump that runs when nobody's using water is telling you something
A silent leak or a failing pressure tank can keep the pump cycling day and night — running up your bill and wearing out an expensive motor at the same time. If your pump clicks on and off every minute or two, or you hear it running at 2 a.m. with every tap closed, have it looked at before the next bill lands.
How to Bring the Cost Down
The nice thing about pump costs is that the biggest savings come from basic upkeep, not fancy equipment. Chase down leaks first — running toilets, dripping faucets, and any suspect line out to a barn or trough. A silent leak that keeps the pump running is the single most common reason a well bill looks wrong. Keep the pressure tank healthy. A good tank lets the pump run in fewer, longer cycles; a waterlogged one makes it start and stop far too often. That matters beyond the wasted water, because every start sends a hard jolt of inrush current through the motor — fewer, longer runs are easier on both your bill and your equipment.
Right-size and maintain the pump. A pump matched to your well and home, kept in good shape, sips less than one that's worn or oversized. And for a big household, it can be worth weighing a constant-pressure (VFD) pump, which ramps the motor up and down smoothly instead of slamming on and off. It steadies your water pressure and cuts down on those hard starts, though it's an investment to weigh against what your home actually needs.
Where the Pump Fits in the Whole Property
Your well pump is just one load out of many. If you're trying to get your arms around the whole place — the house, the barn, the wells, and everything else that plugs in — start with our farm and ranch electricity cost guide, which pulls the big pieces together. And if you're curious how the pump stacks up against everything indoors, what uses the most electricity in a Texas home puts the loads in order. Whatever the pump ends up costing, remember that the rate you pay for every one of those kilowatt-hours is the one piece you can change today.
Same water, cheaper kilowatt-hours
The rate on your bill multiplies every kilowatt-hour your pump uses. Lower the rate and the whole property — well, house, and all — gets cheaper at once. Compare every plan in your ZIP at your real usage in under a minute.

How much does it cost to run a well pump per month in Texas?
For everyday household water, most Texas homes spend only a few dollars a month running the well pump, because it cycles in short bursts to refill the pressure tank rather than running all day. The exact figure depends on your pump size, how deep your well is, how much water you use, and your electricity rate. As an example only, a 1 kW pump running about an hour a day total uses roughly 30 kWh a month, which is around 4 to 5 dollars at a 15-cent rate. Plug in your own pump size and your own rate to get a number that fits your well.
Does a well pump use a lot of electricity?
Not for normal indoor use. A submersible pump draws a fair amount of power while it is actually running, often somewhere in the range of 1 to 2 kW, but it only runs in short spurts to top off the pressure tank, so it adds up to a small share of most bills. It becomes a heavy user only when it has to move a lot of water, such as for irrigation, filling a pool, or watering livestock, or when a leak or a failing pressure tank keeps it cycling nonstop.
Why is my well pump making my electric bill so high?
The usual culprits are a hidden leak, a failing pressure tank, or heavy outdoor water use. A running toilet or a cracked line out to the barn can keep the pump cycling all night for water nobody used. A waterlogged pressure tank makes the pump start and stop far too often, which wastes power and wears out the motor. And sprinklers or filling a pool can multiply the runtime. If the pump runs when every tap in the house is closed, have it checked.
Does the depth of my well affect the electricity cost?
Yes. The deeper the water sits, the harder the pump works to lift each gallon, so a deep well uses more energy per gallon than a shallow one. That is one reason two homes with the same size pump can land on different pump costs. The one drawing from a deeper water table simply pays a little more for the same amount of water.
