Trenching Cost Calculator


Trenching is a common construction process used for laying utilities, cables, or drainage systems. However, determining the cost of trenching for your project is essential for budgeting. Our Trenching Cost Calculator simplifies this process, providing you with a quick estimate of the expenses involved. In this article, we'll guide you on how to use this calculator effectively.


The cost of trenching is based on calculating the volume of the trench and then multiplying it by the cost per linear foot. The formula can be explained as follows:

Estimated Trenching Cost = (Trench Length (feet) × Trench Width (inches) × Trench Depth (inches) / 12) × Cost Per Linear Foot

How to Use

Our Trenching Cost Calculator is designed for ease of use:

  1. Enter the length of the trench in feet.
  2. Input the width of the trench in inches.
  3. Specify the depth of the trench in inches.
  4. Provide the cost per linear foot for trenching.
  5. Click the "Calculate" button.

The calculator will instantly provide you with an estimated total cost for your trenching project.


Suppose you need to trench a 50-foot-long, 12-inch-wide, and 18-inch-deep trench, and the cost per linear foot is $10. Input these values into the calculator. After clicking "Calculate," you'll receive an estimated trenching cost based on your specifications.
