Compost calculator
Measure your project. Make a clearer plan.
Calculate compost volume, whole bags, and local supplier costs.
Clear math. Better decisions.
A worked example
A 200 sq ft bed at 2 inches deep needs 1.23 cu yd before extra.
Before you order
- Calculate compost volume, whole bags, and local supplier costs.
- Enter your chosen application depth; this tool does not prescribe a soil amendment rate.
Good questions.
Where do the prices come from?
You enter actual supplier prices. A blank price is unknown; enter zero only when that item is free or deliberately excluded. Taxes and installation are excluded unless a field explicitly includes them.
Can I use metric measurements?
Yes. The unit selector converts dimensions and unit prices. Results use whole packages where applicable. Starting dimensions are examples; confirm product specifications before ordering.
