Well Casing Cost Calculator

Estimate the cost of well casing from the cased depth and the $/ft on your driller’s quote — the pipe that lines the borehole and seals out surface water.

Planning estimate: this is a planning estimate from the numbers you enter and standard reference quantities — not a bid or a contract. Get itemized written quotes from licensed contractors and confirm measurements before you commit.

Calculator

ft
The length of the borehole that is lined with casing.
$/ft
The per-foot casing rate from your quote (steel costs more than PVC).
Estimated total$900.00
Cased depth60 ft
Your $/ft of casing$15.00

Casing 60 ft at $15.00/ft is about $900.00. Steel vs PVC casing and the diameter change the $/ft — enter the figure from your driller’s quote.

Casing is the pipe — steel or PVC — that lines the drilled borehole. It holds the hole open, keeps loose soil and surface water out of your drinking water, and carries the pump. Its cost is separate from the drilling footage rate because the material and diameter, not just the depth, drive the price. This tool isolates that one line so you can check it on its own or slot it into a larger estimate.

Formula

A single multiplication:

casing cost = cased depth (ft) × your $/ft

The per-foot figure is one you enter from a quote. Steel casing runs higher than PVC, and a larger well diameter raises the rate again — so use the number that matches the material and size your driller specified.

Worked example

For 60 ft of casing at $15/ft, the cost is 60 × $15 = $900. Switch to a heavier steel casing at $22/ft and the same 60 ft becomes 60 × $22 = $1,320; deepen the cased section to 90 ft at $15/ft and it is 90 × $15 = $1,350. The line moves with both the rate and the length.

Steel vs PVC and how much to case

How much of the well is cased depends on the geology and on code. In unstable or shallow formations the casing may run most of the depth; in solid bedrock the lower borehole can often stand open below a cased upper section. Your driller and the local health department set the minimum casing depth and the grouting (the seal around the casing) that protects the aquifer.

Material matters for both price and life: steel is stronger and tolerates more, PVC is cheaper and resists corrosion. Neither choice is yours alone to make — it follows the well design. Casing is usually one line inside a full drilling bid; to see it in context, use the well drilling cost or complete well system calculators. This is a planning estimate on your figures.

Frequently asked questions

How much does well casing cost?
It is the cased depth times your per-foot price. Casing 60 ft at $15/ft is 60 × $15 = $900. The $/ft depends on the material (steel or PVC) and the well diameter, so enter the figure from your own quote rather than a generic rate.
Is steel or PVC casing better?
Both are common. Steel is stronger and handles rougher formations; PVC is cheaper and does not corrode. The right choice is part of the well design and depends on your geology and local code — it changes the $/ft you should enter here.
How much of the well needs casing?
It varies. Shallow or loose ground may need casing along most of the depth; solid bedrock can often stay open below a cased upper section. The minimum cased depth and grouting are set by your health department and driller, not by cost.
Is casing included in the drilling price?
Sometimes it is bundled into a per-foot rate, sometimes it is a separate line. Check your quote. This tool prices casing on its own so you can compare bids that itemize it differently.
