Enter the total mulch area (ft) and the total mulch depth (in) into the Mulch Weight Calculator. The calculator will evaluate the Mulch Weight. 

Mulch Weight Formula

The following two example problems outline the steps and information needed to calculate the Mulch Weight.

MUL = A * D/12 * 22.22


  • MUL is the Mulch Weight (pounds)
  • A is the total mulch area (ft) 
  • D is the total mulch depth (in) 

How to Calculate Mulch Weight?

The following steps outline how to calculate the Mulch Weight.

  1. First, determine the total mulch area (ft). 
  2. Next, determine the total mulch depth (in). 
  3. Next, gather the formula from above = MUL = A * D/12 * 22.22.
  4. Finally, calculate the Mulch Weight.
  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.

total mulch area (ft) = 300

total mulch depth (in) = 5

MUL = A * D/12 * 22.22 = ?
