Quick answer
Drilling a residential water well usually costs $20–$30 per foot, plus installation and casing. A typical 200 ft well comes to about $6,000–$16,000 for drilling and installation, and a pump, pressure tank and wiring add roughly $1,500–$4,000.
What the Well Drilling Cost Calculator does
Enter the expected depth and ground conditions. The calculator prices drilling per foot, adds casing and installation, and optionally a pump, pressure tank and water treatment. Depth is the biggest unknown — local drillers and state well logs are the best guide.
The formula
Total = depth × ($20–$30) × ground factor + depth × ($10–$50) installation + pump & tank + treatment.
Worked example
300 ft in hard rock with pump and softener: $7,200–$12,150 + $3,000–$15,000 + $1,500–$4,000 + $500–$2,500 = about $12,200–$33,650.
How to use the Well Drilling Cost Calculator
- Enter the likely depth for your area.
- Choose the ground type.
- Add pump and treatment if needed.
Frequently asked questions
