Enter the excavated volume and the waste factor into the calculator to determine the total soil waste. This calculator helps in estimating the additional soil that will be wasted due to factors like compaction, spillage, and decay.

Soil Waste Formula

The following formula is used to calculate the total soil waste.

TW = V * (WF / 100)

Variables:

  • TW is the total soil waste (cubic yards)
  • V is the excavated volume (cubic yards)
  • WF is the waste factor (percentage)

To calculate the total soil waste, multiply the excavated volume by the waste factor percentage divided by 100.

What is Soil Waste?

Soil waste refers to the extra soil that is not used in construction or landscaping projects. It includes the soil that is removed during excavation and cannot be reused due to various reasons such as contamination, excess moisture, or unsuitable composition. Proper estimation of soil waste is crucial for project planning and cost estimation, as well as for environmental considerations.

How to Calculate Soil Waste?

The following steps outline how to calculate the Soil Waste.


  1. First, determine the excavated volume (V) in cubic yards.
  2. Next, determine the waste factor (WF) as a percentage.
  3. Next, gather the formula from above = TW = V * (WF / 100).
  4. Finally, calculate the Total Soil Waste (TW) in cubic yards.
  5. 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.

Excavated Volume (V) = 50 cubic yards

Waste Factor (WF) = 15%
