Quick answer:
How much does a well pump replacement cost? Most residential well pump replacements cost $1,500 to $4,000 fully installed. Well depth, pump type, and replacement difficulty drive most of the variation. Use the calculator below for a personalized range, then compare it against two to four written contractor quotes. For the full cost breakdown by component, see our well pump replacement cost guide.
Most homeowners find out they need a pump replacement at the worst possible moment. This calculator gives you a realistic price range to work from before any contractor quotes arrive, so you can evaluate bids with confidence rather than desperation.
The estimate is based on published cost ranges from our parent guide, weighted for the variables that actually move price: pump type, well depth, home demand, regional labor rates, and whether you are also replacing the pressure tank or controls.

What affects well pump replacement cost
Well depth
The single biggest cost driver. Every 100 feet adds roughly $500 to $1,000 in pipe, wire, and labor. A 100-foot well costs roughly half what a 400-foot well costs for the same pump.
Pump type and horsepower
Submersible pumps dominate residential wells over 25 feet and run $300 to $1,500 for the unit. Shallow jet pumps are cheaper at $200 to $700. Constant-pressure (VFD) systems add $800 to $2,000 for steadier pressure.
Home demand and flow rate
A four-person household with a small irrigation load needs more gallons per minute than a one-person cabin. Higher demand sometimes means a larger pump, larger pressure tank, and slightly higher equipment cost.
Regional cost factor
Northeast and West Coast labor runs 15 to 30 percent above the national average. Rural Southeast and parts of the Midwest run 5 to 15 percent below. Competitive markets with high well density are usually the cheapest.
Replacement difficulty
A clean pull on a recent install is fast and cheap. A stuck pitless adapter, corroded torque arrestor, or compromised wiring can add hours of labor. Difficult site access (steep, muddy, no truck path) raises labor too.
Additional components
Replacing the pressure tank or control box at the same time adds $400 to $1,100 but avoids a second service call later. If either is more than 8 years old, replace it now.
Typical Well Pump Replacement Cost by Type and Depth
| System type | Well depth | Total installed |
|---|---|---|
| Shallow well jet pump | Under 25 ft | $800 to $1,800 |
| Deep well jet pump | 25 to 100 ft | $1,200 to $2,500 |
| Submersible pump | 100 to 250 ft | $1,500 to $3,000 |
| Submersible pump | 250 to 400 ft | $2,800 to $5,500 |
| Submersible pump | 400 ft or deeper | $4,000 to $8,000+ |
| Constant-pressure (VFD) | Any depth | Add $800 to $2,000 |
Ranges assume scheduled weekday installation. Emergency or weekend service typically adds 25 to 50 percent to the labor portion.
Well Pump Replacement Cost by Depth
Well depth is the single biggest variable in pump replacement cost. The same submersible pump unit can cost $1,500 to install in a 100-foot well or $5,000 to install in a 400-foot well because deeper wells require more drop pipe, more electrical wire, and significantly more labor to pull and reinstall the pump.
Cost ranges by depth (assuming a quality submersible pump):
- Shallow wells under 100 feet: $1,200 to $2,500 fully installed
- Mid-depth wells 100 to 250 feet: $1,500 to $3,000 fully installed
- Deeper wells 250 to 400 feet: $2,800 to $5,500 fully installed
- Deep wells 400 feet or more: $4,000 to $8,000 or more fully installed
For deep well pump replacement specifically, expect labor and pipe costs to represent a larger share of the total bill than the pump unit itself. A 350-foot well replacement might break down as $500 for the pump, $1,200 for drop pipe and wire, and $2,000 for labor, with the remainder covering pressure tank or control work. Use the calculator above to estimate your specific replacement cost based on your actual well depth.
