Enter the width, length, and depth of the footing into the calculator to determine the volume of the footing in cubic feet. This calculator helps in estimating the amount of concrete needed for constructing footings.

Footing Volume Formula

The following formula is used to calculate the volume of a footing.

V = W * L * D

Variables:

  • V is the volume of the footing (cubic feet)
  • W is the width of the footing (feet)
  • L is the length of the footing (feet)
  • D is the depth of the footing (feet)

To calculate the volume of a footing, multiply the width (W) by the length (L) and then by the depth (D) of the footing.

What is a Footing?

A footing is a part of the foundation that helps to distribute the load of the structure over a larger area. It is typically made of concrete and is located at the base of a structure to provide support and prevent settling. Footings are essential in construction to ensure the stability and longevity of buildings and other structures.

How to Calculate Footing Volume?

The following steps outline how to calculate the volume of a footing.


  1. First, determine the width (W) of the footing in feet.
  2. Next, determine the length (L) of the footing in feet.
  3. Next, determine the depth (D) of the footing in feet.
  4. Next, gather the formula from above = V = W * L * D.
  5. Finally, calculate the Footing Volume (V) in cubic feet.
  6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Width (W) = 2 feet

Length (L) = 4 feet

Depth (D) = 0.5 feet
