How this calculator works
The result depends on the numbers you enter and the assumptions shown below.

Mulch volume = area × depth. A 2–3 inch layer suppresses weeds effectively; 4 inches for pathways. One cubic yard covers 100–160 sq ft at 2–3 inches deep.

Review the inputs carefully and treat the output as an estimate. For decisions involving money, taxes, health, law, or security, compare the result with trusted professional guidance when needed.
