Well Drilling Cost Calculator (2026): Estimate New Water Well Cost

Quick answer:

Most residential well drilling projects in 2026 land between $5,500 and $18,000 fully equipped, with deep or hard-rock wells reaching $25,000 or more. Depth, geology, and whether you include a pump and pressure system drive most of the spread. Use the calculator to your right (or above on mobile) for a personalized range, then compare it against two to four written contractor quotes. For the full breakdown by component, see our well drilling cost guide.

This calculator estimates the realistic price range to drill and equip a new water well on your property in 2026. It is built on national drilling pricing data weighted for depth, geology, casing size, pump system, trenching, and regional labor cost. Local quotes will still vary because actual rock conditions, water yield, and contractor pricing only become clear once a driller is on site.

2026 Pricing

What does it really cost to drill a well in 2026?

Most residential water wells in 2026 cost between $5,500 and $18,000 fully equipped. Drilling itself is priced per foot, and contractors then add casing, the pump and pressure tank, trenching from the well to the house, electrical hookup, permits, and inspections.

Scenario	Typical depth	Total installed range
Shallow well (easier soil)	50 to 100 ft	$3,000 to $7,500
Standard residential well	100 to 200 ft	$5,500 to $12,000
Moderate-depth well	200 to 300 ft	$10,000 to $18,000
Deep well (hard rock)	300 to 500+ ft	$15,000 to $30,000+

Ranges are typical homeowner totals fully equipped, with significant variation based on geology and region.

How this well drilling cost calculator builds your estimate

The calculator combines six homeowner-supplied inputs into a planning range:

Depth drives the largest single cost variable, since drilling and casing scale per foot.
Geology sets the per-foot multiplier. Soft soil drills faster than hard rock.
Casing diameter changes both material cost and rig productivity.
Pump and pressure system adds a flat band (or zero, if you only want drilling and casing).
Trenching distance from the well to the house adds excavation, line, and backfill.
Region applies a final cost multiplier to drilling and permits.

The tool blends those factors into a low and high estimate so you walk into contractor conversations with a realistic planning range, not a single dollar figure that pretends to be a quote.

The biggest factors that change well drilling cost

Depth

Drilling is priced per foot, so doubling depth roughly doubles the drilling and casing line. Going from a 150-foot well to a 350-foot well at the same per-foot rate often adds $7,000 to $12,000.

Ground conditions

Soft soil and sand drill quickly. Mixed soil with some rock is the typical case. Hard rock raises the per-foot rate by 25 to 40 percent because of slower progress, more bit wear, and tougher casing work.

Casing diameter

4-inch casing is the budget option, 6-inch is the standard residential choice, and 8-inch is built for higher flow homes or small farms. Each step up adds roughly 10 to 20 percent to drilling and casing cost.

Pump and pressure system

A basic submersible pump and pressure tank package adds $1,500 to $3,000. A high-output system with larger pump, larger pressure tank, or a constant-pressure controller can add $3,500 to $6,500.

Location, permits, and access

Strict-permitting jurisdictions, long trench runs from the well to the house, steep or wooded sites, and tight access for the rig all push cost up. Rural sites with easy truck access and lighter permitting tend to come in lower.

Example well drilling estimates for common setups

Shallow well

Soft soil, 100 ft, 6" casing, basic pump, average region

A straightforward shallow well in soft soil with a basic pump and pressure tank. Roughly 75 to 100 feet of drilling, light trenching to a nearby house, and standard permitting.

Typical range: $5,000 to $9,000

Standard residential

Mixed soil and some rock, 150 ft, 6" casing, basic pump, average region

The most common scenario nationally. Mixed-condition drilling, standard casing, basic pump and pressure tank, and a 25 to 75 foot trench to the house.

Typical range: $8,500 to $14,000

Deep hard-rock

Hard rock, 400 ft, 6" casing, high-output system, high-cost region

Questions to ask a well drilling contractor before you hire

Are you licensed and insured in my state, and can you share your license number?
What exactly is included in this estimate, line by line?
How deep do you expect this well to be, and what are you basing that on?
What happens if you do not hit enough water at the expected depth?
What casing size and material do you recommend, and why?
Will you perform yield testing and water quality testing, or is that a separate vendor?
Who handles permits and inspections, and are those fees in the quote?
What warranty do you provide on drilling, casing, and the pump system?
Will you give me a written contract and a final well log when the job is finished?
Can you share references from recent nearby jobs in the same geology?

When drilling a new well makes more sense than more repairs

Replacing a worn pump or pressure tank is usually the right move when the well itself is producing well, the casing is sound, and water quality is good. A pump-only replacement typically lands between $1,500 and $4,000, far cheaper than drilling new.

Drilling a new (or deeper) well becomes the smarter play when:

The existing well has lost yield as the water table dropped
The casing is corroded, collapsed, or contaminated and cannot be rehabilitated
Repeated rehabilitation, acid treatment, or pump replacements are not solving the underlying problem
You need a higher flow rate than the existing well can deliver
Local water quality has changed and a different aquifer offers cleaner water

If you are not sure which side of that line you are on, start with the well pump replacement cost guide and the well pump replacement cost calculator. If a pump-only fix gets you back in service for under $4,000, that is almost always the better path. Also worth reviewing if you suspect water quality is the issue: our well water testing cost guide and well water treatment calculator.

FAQ

How accurate is this calculator?

This calculator produces a planning-grade range, not a contractor quote. It uses 2026 national drilling pricing for depth, geology, casing diameter, pump system, trenching distance, permits, and a regional cost factor. Most homeowners find their actual contractor quotes fall within the calculator's estimated range, but local geology and contractor pricing can move real quotes meaningfully above or below it. The calculator is most accurate when you have realistic information about expected depth (from neighbors, state geological survey data, or your local well drilling contractor) and accurate geology assessment for your area. For projects where depth or geology is uncertain, the high end of the calculator's range is the more conservative budget anchor. Once you have the estimate, request two to four written line-item quotes from licensed local contractors to convert it into a binding price.

What is included in a per-foot price?

A per-foot drilling rate normally covers the actual drilling labor, the casing material installed in the borehole, basic well log documentation, and well development. It usually does not cover the pump, pressure tank, trenching from the well to the house, electrical hookup, water testing, or permit fees. Always ask each contractor for a written line-item breakdown so you know exactly what is in their per-foot number. The biggest hidden cost in well drilling quotes is unbundled pricing where the per-foot rate looks competitive but excluded items (pump, pressure tank, trenching, electrical, permits) push the total $3,000 to $7,000 above competitors offering all-in pricing. Request itemized quotes from every contractor you talk to so you can compare like-to-like rather than comparing per-foot rates without context.

Do I have to pay extra for permits and inspections?

Most jurisdictions require a permit and at least one inspection for a new residential well. Permit and inspection fees vary widely by state and county, ranging from $250 to $1,200 in total. Some contractors include permit and inspection fees in their quote and some bill them separately. Strict-permitting regions (parts of California, the Northeast, and certain protected watersheds) sit at the upper end of that range. Ask each contractor whether their quote includes permit fees, inspection fees, water quality testing required by the jurisdiction, and well log filing. Some areas also require post-drilling inspections by the local health department before the well can be put into service, which can add $150 to $500.

How do I estimate the depth if I do not have an existing well?

Start with neighbors. Ask two or three nearby homeowners what depth their wells were drilled to and what year they were drilled. Your local well drilling contractor and your state geological survey usually have a sense of typical depths for your area, and most state databases publish well log data by parcel that you can search online. As a rough national benchmark, most residential wells fall between 100 and 300 feet, with deeper wells more common in dry, mountainous, or hard-rock regions. Wells in coastal sandy soil often go shallower (50 to 150 feet); wells in hard-rock regions like New England, Appalachia, or the Rocky Mountains commonly run 300 to 500 feet or deeper. The depth your contractor actually drills depends on where they hit usable water yield, which only becomes clear during drilling, so neighbor data and state databases give you a planning estimate but not a guarantee.

Can I finance a new well?

Yes. Many homeowners finance a new well with a home equity loan, HELOC, personal loan, or a contractor financing program. The USDA Rural Development program also offers loan and grant programs for water systems on qualifying rural properties through their Single Family Housing Repair Loans and Grants program. Some states and counties offer low-interest loan programs specifically for residential well drilling, particularly in regions where municipal water is not available. Get the written contract and full cost estimate first, then compare financing options on overall interest rate, term length, and any prepayment penalties. For lower-income rural homeowners, the USDA grant component can cover part of the project cost without repayment requirements; check eligibility through your local USDA Rural Development office before committing to commercial financing.

How long does it take to drill a residential well?

Most residential well drilling projects take 1 to 3 days of actual drilling time once the rig is on site. The full project timeline including permit approval, contractor scheduling, drilling, casing, pump installation, trenching, electrical hookup, water testing, and final inspection typically runs 2 to 6 weeks. Permit approval alone takes 1 to 4 weeks in most jurisdictions. Strict-permitting regions and seasonal demand peaks (spring through summer in most of the country) push timelines toward the longer end. Active drilling itself runs faster in soft soil (one day for a 150 to 200 foot well) and slower in hard rock (two to four days for the same depth). Most contractors will not start drilling until permits are approved and a written contract is signed.

What is the difference between a drilled well and a dug well, and how does cost compare?

A drilled well is created with rotary or percussion drilling equipment that bores a narrow shaft (typically 4 to 8 inches in diameter) hundreds of feet down to reach a stable aquifer. A dug well is excavated with backhoes or hand tools, typically 3 to 20 feet wide and 10 to 30 feet deep, drawing from shallow groundwater. Drilled wells are dramatically more reliable, deliver consistently safe water from deeper aquifers, and last 30 to 50 years or more, which is why they are the standard for new residential wells in 2026. Dug wells cost $1,500 to $5,000 to construct (significantly less than drilled wells) but are vulnerable to surface contamination, can dry up during droughts, and rarely meet modern health code for new construction. Most jurisdictions no longer permit new dug wells. For a complete comparison, see our dug well vs drilled well guide.
