BEHIND THE NUMBERS

Clear math. Better decisions.

Total volume = bed area × unfilled depth × allowance. Compost = total × compost percentage; remaining blend = total − compost.

A worked example

An 8 × 4 ft bed with 12 inches to fill holds 32 cu ft. A 30% share is 9.6 cu ft before extra.

Before you order

  • Split raised-bed fill into two volume components and price each separately.
  • The 30% starting share is a math example, not a recommended soil recipe. Both prices use the displayed volume unit.

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.
