How Much Mulch Do I Need (Step-by-Step)?

This online mulch estimator determines the volume and the number of bags of mulch needed for the completion of a project. And, here we are going to show you examples for mulch calculations, let’s take a look!

To calculate the volume needed, follow the given steps:

  • Measure the length & width of the area for which you are going for the construction.
  • Find out the area of the surface from length & width. \((A = L \times W)\).
  • Determine the depth of the surface.
  • Find out the volume by multiplying the area and depth.
  • The volume obtained is the volume needed for the mulch to complete the project.

Let’s have an example:


The surface is \(12 ft\) long, 8ft wide with the depth of \(6 ft\). Then find how much mulch do I need for landscaping?


\(L = 12 ft\)

\(W = 8 ft\)

\(D = 6 ft\)

So, find the area by,

\(A = L \times W\)

\(A = 12 \times 8\)

\(A = 96 ft^2\)


Calculate the volume by using the formula:

\(V = A \times D\)

\(V = 96 \times 6\)

\(V = 576 ft^3\)
