Well Pump Cost by Depth

Depth is the single biggest driver of well pump replacement cost — more drop pipe, more submersible wire, and more time to pull the old assembly. This table holds horsepower constant (1 HP, the most common residential size) and varies only depth, so you can see exactly what depth alone adds.

By horsepower (at a typical 150 ft depth)

Horsepower	Pump unit	Labor	Total installed
0.5 HP	$400–$700	$825–$1,650	$1,225–$2,350
0.75 HP	$500–$900	$825–$1,650	$1,325–$2,550
1 HP	$600–$1,200	$825–$1,650	$1,425–$2,850
1.5 HP	$900–$1,800	$825–$1,650	$1,725–$3,450
2 HP	$1,200–$2,500	$825–$1,650	$2,025–$4,150

By depth (at 1 HP)

Well depth	Pump unit	Labor	Total installed
50 ft	$600–$1,200	$600–$1,200	$1,200–$2,400
100 ft	$600–$1,200	$600–$1,200	$1,200–$2,400
150 ft	$600–$1,200	$825–$1,650	$1,425–$2,850
200 ft	$600–$1,200	$1,050–$2,100	$1,650–$3,300
250 ft	$600–$1,200	$1,275–$2,550	$1,875–$3,750
300 ft	$600–$1,200	$1,500–$3,000	$2,100–$4,200
350 ft	$600–$1,200	$1,725–$3,450	$2,325–$4,650
400 ft	$600–$1,200	$1,950–$3,900	$2,550–$5,100

What moves the price beyond this table

• Pressure tank — if yours is old or waterlogged, replacing it alongside adds $800–$1,500 but saves a second service call.
• Control box — for 3-wire pumps, a worn or corroded box adds $150–$600 and is worth replacing alongside the pump.
• Well casing diameter and access — a narrow or hard-to-reach wellhead can add labor time not captured in a national average.
• Local labor rates — well contractor rates vary meaningfully by region; these ranges are national.
