Well drilling is priced by the foot into ground nobody can fully see — which is why quotes feel like guesses and vary wildly. This estimator gives you a realistic 2026 range from the three factors that actually drive price: depth, geology, and region. Use it to sanity-check quotes, not replace them.
What the money buys
- Drilling + casing ($25–$65/ft): the hole, steel or PVC casing through unstable ground, and grouting the annular space to keep surface water out.
- Well development and yield test: clearing drilling debris and verifying flow — ask for the measured GPM in writing, then check it against your household's needs with our well water usage calculator.
- Completion ($4,000–$7,000): submersible pump, drop pipe, pitless adapter, pressure tank, wiring, and trenched service line to the house.
- Permit ($100–$800): most states require a well permit and a licensed driller who files the well log.
How to keep the project honest
- Pull neighboring well logs first — most states publish them. Knowing nearby wells hit water at 180 ft turns a per-foot gamble into an informed estimate.
- Get per-foot pricing itemized: drilling rate, casing rate, grouting, development, and completion as separate lines — plus the rate if drilling must go deeper than expected.
- Ask what happens on a dry hole: reputable drillers charge a reduced rate for a dry bore and credit part of it toward a second attempt. Get the policy in writing before drilling starts.
- Test the water after completion: a new well needs a full lab panel before you drink from it — and possibly treatment equipment after.
Frequently Asked Questions
How much does it cost to drill a well in 2026?
Most residential wells cost $25–$65 per foot to drill and case, putting a typical 200-foot well at $5,000–$13,000 for drilling alone. A complete system — pump, pressure tank, wiring, and hookup — typically adds $4,000–$7,000, bringing the all-in total for an average well to $9,000–$20,000.
How deep does a residential well need to be?
Whatever depth reaches reliable water in your area — commonly 100–400 feet, with 150–300 typical in much of the U.S. Your best predictor is neighboring wells: state well logs are public in most states, and local drillers know the aquifer. Deeper isn't automatically better, but too shallow risks seasonal dry-outs and surface contamination.
Why do well drilling quotes vary so much?
Because the driller is quoting per foot into unknown ground. Hard rock drilling costs more per foot than sand or clay; some quotes include casing, grouting, and development while others itemize them; and mobilization to remote sites adds cost. Get quotes itemized per foot with casing and completion listed separately.
Does a new well guarantee good water?
No — a new well guarantees a hole, not quality or quantity. Reputable drillers test yield on completion, but water chemistry (iron, hardness, arsenic) is site luck. Budget for a full lab test after completion and possible treatment equipment before you consider the project done.
