Mulch calculator

Estimate mulch by cubic yards, cubic feet, or bags.

Enter the bed size and depth to estimate bulk mulch and common bag counts, including a quick refresh mode for topping up existing beds.

Bulk vs bagged mulch

Bulk cubic yards

  • Usually better for larger beds and full yard refreshes.
  • Often delivered by the cubic yard.
  • Plan access for delivery and dumping.

Individual bags

  • Useful for small beds, touch-ups, and tight storage.
  • Easier to transport in smaller batches.
  • Compare bag size before comparing bag counts.

Mulch depth guidance

Two to three inches is common for fresh mulch. If you are topping off existing mulch, use refresh mode or enter a thinner custom depth.
