Culvert Cost Calculator


Culverts play a crucial role in managing water flow under roads and driveways. When planning a construction project, it’s important to estimate the cost of culvert installation accurately. The Culvert Cost Calculator simplifies this process, allowing you to calculate the expenses associated with culverts based on their length, diameter, and the chosen material.


The cost of a culvert is determined by multiplying the culvert’s length (in feet) by the cost per foot, which varies depending on the chosen material (corrugated metal, concrete, plastic, or other).

Estimated Culvert Cost ($) = Culvert Length (feet) × Cost per Foot (based on material)

How to Use:

  1. Enter the length of the culvert in feet in the “Culvert Length (feet)” field.
  2. Specify the diameter of the culvert in inches in the “Culvert Diameter (inches)” field.
  3. Select the culvert material from the dropdown menu in the “Culvert Material” field.
  4. Click the “Calculate” button.

The calculator will display the estimated cost of the culvert installation.


Suppose you need a culvert that is 20 feet long, has a diameter of 12 inches, and you choose a corrugated metal material for it.

  • Enter 20 in the “Culvert Length (feet)” field.
  • Input 12 in the “Culvert Diameter (inches)” field.
  • Select “Corrugated Metal” from the dropdown menu in the “Culvert Material” field.
  • Click the “Calculate” button.

The calculator will display an estimated culvert cost of $200.
