Concrete Foundation Cost Calculator


When planning a construction project that involves a concrete foundation, understanding the associated costs is crucial for budgeting and project management. The Concrete Foundation Cost Calculator is a valuable tool that helps you estimate the total cost of your concrete foundation based on specific project details.


To calculate the total cost of a concrete foundation, we use the following formula: Total Cost = (Foundation Length × Foundation Width × (Foundation Depth / 12) / 27) × Cost Per Cubic Yard ($)

How to Use

  1. Enter the length of the foundation in feet.
  2. Input the width of the foundation in feet.
  3. Specify the depth of the foundation in inches.
  4. Enter the cost per cubic yard of concrete in dollars.
  5. Click the “Calculate” button to obtain the estimated total cost.


Suppose you are planning to build a concrete foundation for a structure. The foundation needs to be 20 feet in length, 10 feet in width, and have a depth of 8 inches. The cost per cubic yard of concrete is $120.

Foundation Length (feet): 20 Foundation Width (feet): 10 Foundation Depth (inches): 8 Cost Per Cubic Yard ($): $120

By clicking the “Calculate” button, you will receive the estimated total cost for the concrete foundation:

Total Cost: $800
