When planning an excavation for a foundation, pool, or landscaping project, knowing the total volume of soil to be removed is essential. The Cubic Yard Excavation Calculator helps you determine the volume of your excavation area in both cubic feet and cubic yards.

This is especially useful for estimating the cost of excavation, transportation, and disposal of soil.

Formula to Calculate Excavation Volume

1. Excavation Volume in Cubic Feet

To calculate the volume in cubic feet, multiply the length, width, and depth of the excavation area.

Volume (ft³)=Length (ft)×Width (ft)×Depth (ft)\text{Volume (ft³)} = \text{Length (ft)} \times \text{Width (ft)} \times \text{Depth (ft)}Volume (ft³)=Length (ft)×Width (ft)×Depth (ft)

2. Excavation Volume in Cubic Yards

Since 1 cubic yard = 27 cubic feet, divide the cubic feet volume by 27 to get the cubic yards.

Volume (yd³)=Volume (ft³)27\text{Volume (yd³)} = \frac{\text{Volume (ft³)}}{27}Volume (yd³)=27Volume (ft³)​

Example Calculation

Let’s say you need to excavate an area with these dimensions:

  • Length: 30 ft
  • Width: 10 ft
  • Depth: 4 ft

Step 1: Calculate Volume in Cubic Feet

Volume (ft³)=30×10×4=1200 ft³\text{Volume (ft³)} = 30 \times 10 \times 4 = 1200 \text{ ft³}Volume (ft³)=30×10×4=1200 ft³

Step 2: Convert to Cubic Yards

Volume (yd³)=120027=44.44 yd³\text{Volume (yd³)} = \frac{1200}{27} = 44.44 \text{ yd³}Volume (yd³)=271200​=44.44 yd³

Final Answer:

  • Excavation Volume = 1200 cubic feet
  • Excavation Volume = 44.44 cubic yards

Conclusion

The Cubic Yard Excavation Calculator makes it simple to estimate how much soil or material will be removed during excavation. Whether you’re planning a small garden project or a large construction job, this calculator ensures accurate results and helps with cost estimation and planning.
