What this calculator does
Calculate mulch volume using bed dimensions, depth, waste percentage, and bag size.
Inputs and what they mean
- Dimension unit
- — choice value.
- Length
- — number value.
- Width
- — number value.
- Depth
- — number value.
- Number of equal areas
- — number value.
- Waste allowance
- — number value.
- Volume per bag
- — number value.
How to use it
- Enter the project dimensions and choose their unit.
- Adjust waste, coverage, quantity, and other assumptions.
- Use the rounded purchase estimate as a planning guide.
Formula
Volume = length × width × depth × quantity. Waste is added and the result is converted to cubic yards and user-defined bags.
Worked example
Mulch for a rectangular project
Estimate material volume and whole bags with a 10% allowance.
Reading the result
