How Does the Well Drilling Cost Calculator Work?
This well drilling cost calculator estimates total installation cost based on well type, estimated depth, casing material, pump type, pressure system, terrain difficulty, water testing, and your location. It breaks down costs by drilling, pump/system, and shows a cost-per-foot rate.
Well drilling costs in 2026 range from $1,500 for a shallow driven point well to $30,000+ for a very deep drilled well in hard rock. The single biggest variable is depth — and depth cannot be predicted with certainty before drilling begins. Neighboring properties are the best guide: ask nearby well owners how deep their wells are and at what depth they hit water.
Well drilling is priced per foot drilled — typically $25–$65 per foot for the drilling itself, plus a fixed cost for the casing, pump, pressure tank, and hookup. This means a well that requires 300 ft of drilling costs roughly 2× a well requiring 150 ft. Depth is dictated by local geology and water table, not by choice. Research local well logs (available from your county or state water resources agency) to estimate expected depth before budgeting.
Well Drilling Cost Breakdown by Category
Where the money goes for a typical 150 ft drilled well with steel casing, submersible pump, standard pressure system, and average terrain in 2026.
| Category | % of Total | Typical Cost Range | Notes |
|---|---|---|---|
| Drilling (per foot) | 35–50% | $25 – $65/ft drilled | Hard rock drilling costs more per foot |
| Well Casing | 10–18% | $600 – $3,500 | Steel most common; PVC lighter; stainless premium |
| Well Screen & Gravel Pack | 4–8% | $300 – $1,200 | Filters sediment at the bottom of the well |
| Submersible Pump | 12–20% | $800 – $3,500 | Franklin or Grundfos standard; solar higher |
| Pressure Tank & Controls | 8–14% | $500 – $2,500 | Size matched to household demand |
| Electrical (pump to panel) | 5–10% | $400 – $2,000 | Dedicated 240V circuit required |
| Wellhead & Pitless Adapter | 3–6% | $200 – $800 | Connects well to home water line below frost line |
| Permits & Water Test | 3–6% | $300 – $1,500 | Water test required by most lenders |
Well Depth & Cost by US Region
Average well depth varies dramatically by region based on local geology and water table. Use local well logs from your county health department or state geological survey for the most accurate depth estimate before budgeting.
| Region | Avg Depth | Typical Total Cost | Notes |
|---|---|---|---|
| Great Plains / Midwest | 50–150 ft | $3,500 – $12,000 | Shallow aquifers common, lower cost |
| Southeast | 100–200 ft | $5,000 – $15,000 | Sandy soil, good water availability |
| Pacific Northwest | 150–300 ft | $8,000 – $20,000 | Deeper in some areas, good quality |
| Southwest / Arid West | 200–500 ft | $12,000 – $30,000 | Deep water tables, hard rock drilling common |
| Northeast | 150–400 ft | $10,000 – $28,000 | Bedrock common — hard rock adds cost significantly |
| Appalachian / Mountain | 100–300 ft | $7,000 – $22,000 | Rocky terrain increases drilling cost |
Most US states maintain a public well log database showing the depth, yield, and water quality of every permitted well in the county. Search "[your state] well log database" to find the records for nearby properties. This is the most reliable way to estimate depth and yield before hiring a driller — and it's free.
Well Type Guide
| Well Type | Depth Range | Cost Range | Lifespan | Best For |
|---|---|---|---|---|
| Drilled Well | 50–1,000 ft | $5,000 – $30,000 | 30–50 yrs | Primary residential water — most reliable |
| Driven Point Well | 15–50 ft | $1,500 – $4,000 | 10–20 yrs | Sandy soil, high water table — temporary or secondary |
| Bored / Dug Well | 10–50 ft | $1,500 – $5,000 | 20–30 yrs | Large diameter, high yield in shallow aquifers |
| Artesian Well | 100–500 ft | $8,000 – $25,000 | 40–60 yrs | Pressurized aquifer — no pump needed in some cases |
| Geothermal Well | 150–400 ft | $10,000 – $30,000 | 25–50 yrs | Ground-source heat pump systems — not a water supply well |
For a primary home water supply, a professionally drilled well is the only reliable long-term option. Driven point and dug wells are shallow, vulnerable to surface contamination (bacteria, nitrates from fertilizers), and often go dry in drought years. A properly drilled well reaching a deep, confined aquifer provides clean, reliable water for 30–50 years with minimal maintenance. The higher upfront cost is worth it for a primary water source.
Example Calculation
Drilled well, 150 ft depth, steel casing, submersible pump, standard pressure system, average terrain, basic water test, average US market.

Steel casing (6" diameter, 150 ft):$1,200 – $2,500
Well screen & gravel pack:$400 – $900
Submersible pump (1 HP, 150 ft head):$800 – $1,800

Well Maintenance & Lifespan
A drilled well requires minimal maintenance — far less than a septic system — but the pump and pressure tank do wear out and must be replaced over time. Catching problems early prevents contamination and expensive emergency service calls.
| Task | Frequency | Cost | Notes |
|---|---|---|---|
| Water quality test | Annually | $50 – $300 | Test for bacteria, nitrates at minimum each year |
| Pressure tank inspection | Every 3–5 yrs | $100 – $250 | Check air charge and bladder condition |
| Pump replacement | Every 10–15 yrs | $800 – $2,500 | Submersible pumps wear out — budget for replacement |
| Pressure tank replacement | Every 10–15 yrs | $400 – $1,200 | Bladder tanks fail after 10–15 years typically |
| Well shock chlorination | As needed | $100 – $500 | Kills bacteria after flooding or contamination event |
| Well casing inspection | Every 10 yrs | $200 – $600 | Camera inspection for cracks or corrosion |
Unlike municipal water which is tested thousands of times per year, private well water is only tested when the owner chooses to test it. Bacteria contamination (E. coli, coliform), nitrates from agriculture, arsenic, and other contaminants can be odorless and tasteless — undetectable without a test. Annual water testing costs $50–$300 and is the single most important well maintenance task. Many states offer free testing kits through the health department.
