Mulch Calculator

Work out how much mulch you need in cubic yards or 2 and 3 cubic-foot bags for your garden beds, with cost.

Measure by

Length (ft)

Width (ft)

Total area (if chosen) (ft²)

Depth (in)

Price per yard (bulk) ($)

Price per 2 ft³ bag ($)

How to use it

Measure each bed or enter the total area.
Use 2-3 in for top-ups and 3-4 in for new beds.
Compare the bulk (per yard) and bagged cost.

How it works

Mulch (yd³) = area × depth (in) ÷ 324. One cubic yard = 13.5 bags of 2 ft³ or 9 bags of 3 ft³. Keep mulch a few inches away from tree trunks and house siding.
