Enter the area and desired depth of mulch into the calculator to determine the number of bags of mulch needed.

Bags Of Mulch Formula

The following formula is used to calculate the number of bags of mulch needed for a specific area.

B = (A * D) / S

Variables:

  • B is the number of bags of mulch needed
  • A is the area to be covered in square feet
  • D is the desired depth of mulch in inches
  • S is the size of the mulch bag in cubic feet

To calculate the number of bags of mulch needed, multiply the area to be covered by the desired depth of mulch. Then divide the result by the size of the mulch bag. This will give you the number of bags needed to cover the specified area with the desired depth of mulch.
