Well Drilling Calculator
Drilling a water well costs $25 to $65 per ft complete with casing, or $3,750 to $15,000 total for most residential wells. A typical 150 ft well runs $5,000 to $9,000 including the pump and pressure tank. Enter your depth below to get an itemized estimate.

Defaults & assumptions
Defaults: a typical 150 ft well and US national averages: normal soil, PVC casing, submersible pump with pressure tank. Rocky ground can double the drilling rate. Set pump system to 0 if reusing existing equipment.

Well drilling cost breakdown
A residential water well has two per-foot costs and two fixed ones. Drilling runs $15 to $25 per ft in normal soil, though rock, clay, or a remote site can double it. Casing (the pipe that lines the borehole) adds $10 to $30 per ft installed; PVC sits at the low end, steel at the top. On top of that come the fixed costs: $1,500 to $3,000 for the pump system (submersible pump, pressure tank, wiring) and $400 to $1,000 for permits and water testing. Because the fixed costs don't change with depth, shallow wells cost more per foot than deep ones.
| Well depth | Typical total cost |
|---|---|
| 100 ft | $3,600 to $7,500 |
| 150 ft | $5,000 to $9,000 |
| 200 ft | $6,000 to $13,500 |
| 300 ft | $8,500 to $20,000 |
How the calculator works
Total = depth × drilling rate + depth × casing rate + pump system + permit, testing, and wiring. That mirrors how well contractors quote: per-foot drilling and casing, plus fixed equipment. Default rates reflect published US averages from national cost guides (Angi, HomeGuide, HomeAdvisor, 2026). Not included: water treatment systems ($800 to $3,000 if your water test calls for one), trenching the supply line to the house (roughly $50 to $100 per ft), and geothermal or irrigation wells, which price differently.

Well drilling cost FAQ
How much does it cost to drill a well?
Drilling a residential water well costs $25 to $65 per ft complete with casing, or $3,750 to $15,000 total for most homes. A typical 150 ft well runs $5,000 to $9,000 including the pump, pressure tank, and wiring. Depth is the biggest cost driver: every extra foot adds drilling and casing cost.
What is the cost to drill a well per foot?
Drilling alone costs $15 to $25 per ft. Add casing at $10 to $30 per ft installed and the complete drilled-and-cased price lands at $25 to $65 per ft. Rocky ground, deep water tables, and hard-to-reach sites push toward the top of the range.
How deep does a residential well need to be?
Most residential water wells are 100 to 300 ft deep, with 150 ft a common average. Depth depends on your local water table: neighbors’ well logs and your county’s well records are the best guide. Deeper wells cost more but are less likely to run dry or pick up surface contamination.
What does a well pump and pressure tank cost?
A submersible well pump costs $400 to $2,000 installed depending on horsepower and depth rating, and a pressure tank adds $300 to $500. Budget $1,500 to $3,000 for the complete pump system with wiring, which is the fixed equipment cost on top of per-foot drilling.
