Mulch Calculator

Convert bed measurements into bulk mulch yards and whole bags.

01 / Your project

Measure. Adjust. Calculate.

Example values are editable, not installation specifications. A $0 price means costs have not been entered.

cubic yards to order
Measured area

Whole packages round up. Prices include only the items you enter. Delivery, tax and installation may be extra.

How to calculate

Enter the additional depth you need, not the final depth if mulch already exists. The 2 cu ft bag yield is editable.

Cubic yards = length × width × depth ÷ 324 × (1 + allowance / 100)

Worked example

Length (ft): 16 · Width (ft): 12 · Material depth (in): 3 · Bag yield (cu ft): 2 · Extra material (%): 10.

These inputs produce 1.96 cubic yards to order. Change the measurements above to match your project.

Before you order

Keep mulch clear of trunks and building details. Subtract areas occupied by large hardscape features before calculating.

For an irregular footprint, split the project into rectangles. Calculate each section and combine unrounded quantities before rounding the final order. Ask the supplier to confirm product yield and available package sizes.

Common questions

Is the allowance an installation recommendation?

No. It is an editable purchasing buffer. Cuts, spills and product requirements vary. Confirm the allowance for your layout.

Does this include installation costs?

Only prices you explicitly enter are included. A material-only result is not an installed quote. Request an itemized quote for site preparation, access, removal, drainage, labor, delivery and tax.
