Geothermal Loop Borehole Cost Estimator
Estimate the vertical drilling for a ground-source heat pump loop field — total bore footage, number of boreholes, and drilling cost by ground type.
Ground type
Estimated loop-field drilling
Drilling cost range
$3,600 – $9,000
Total bore length
450 – 600 ft
Boreholes
2 – 3 holes
Heads up: drilling is 50–70% of the total loop-field cost — the heat pump, headers & connections are separate. This is the loop-field drilling estimate only.
2025–2026 market estimate. Actual cost depends on local geology, water table, site access and permits — always confirm with a licensed driller before you budget.
