Concrete Footing Calculator
When planning any construction project—whether it’s a house, boundary wall, or commercial building—concrete footing plays a critical role in providing a strong foundation. One of the biggest challenges builders and homeowners face is accurately estimating how much concrete is needed and how much it will cost.
This is where the Concrete Footing Calculator becomes an essential tool. It helps you quickly calculate the volume of concrete required in both cubic feet and cubic yards, along with an estimated cost based on your input.
In this detailed guide, you’ll learn how the calculator works, how to use it, real-life examples, benefits, tips, and answers to common questions.
What is a Concrete Footing Calculator?
A Concrete Footing Calculator is an online tool designed to estimate the amount of concrete required for footings based on dimensions such as length, width, and depth. It also calculates the total cost based on the price per cubic yard.

Example Calculation
Let’s understand with a practical example:
- Length: 20 feet
- Width: 2 feet
- Depth: 1 foot
- Cost per cubic yard: $120
Step 1: Calculate Volume (Cubic Feet)
Volume = Length × Width × Depth
= 20 × 2 × 1
= 40 cubic feet
Step 2: Convert to Cubic Yards
1 cubic yard = 27 cubic feet
Volume = 40 ÷ 27
= 1.48 cubic yards
Step 3: Calculate Cost
Total Cost = 1.48 × 120
= $177.60
So, you will need approximately 1.48 cubic yards of concrete and it will cost around $177.60.
