Work out borewell depth cost instantly with clear inputs, formula shown and shareable results.
Borewell drilling is priced in slabs because deeper drilling is slower and harder on the bit: a lower rate applies to the first stretch and a higher one beyond it. Casing, cap and accessories are a separate lump sum, so the average cost per metre rises steadily with depth.
Drilling cost
Cost = min(depth, 60) x first rate + max(depth - 60, 0) x deeper rate
Total
Total = drilling cost + casing and accessories
Cost = min(depth, 60) x first rate + max(depth - 60, 0) x deeper rate. Borewell drilling is priced in slabs because deeper drilling is slower and harder on the bit: a lower rate applies to the first stretch and a higher one beyond it.
No. Yield depends on which aquifer is intercepted, not on depth alone. Drilling past a productive zone into hard rock adds cost without adding water.
This calculator takes 4 inputs: Total drilling depth, Rate for the first 60 metres, Rate beyond 60 metres, Casing and accessories. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
