Measure once. Compare clearly.

Raised Bed
Soil Calculator

A soil plan for one bed or your whole garden. Start with inside measurements, then compare your own bagged and bulk quotes.

The interactive calculator needs JavaScript. You can still calculate manually: inside length × inside width × fill depth × number of beds, using one length unit throughout. Add the optional reserve, then round up to whole bags or supplier increments. Read the complete method.

1 Your raised beds

Measure inside the bed. Fill depth is the thickness of the material you are buying, after any existing fill.

Extra reserve (%)

Optional, set by you. 0% adds no reserve. Purchase rounding is shown separately.

Input limits: 20 bed sizes, 100 beds per size; length/width ≤ 100 m, depth ≤ 10 m; reserve 0–100%. These are tool limits, not growing recommendations.

Optional

Use up to three quotes for the same fill material. Blank prices and fees mean unknown. Enter 0 only for a confirmed zero charge.

Measure the fill space.

Use inside dimensions and the depth of the material you are buying. Existing soil or other layers reduce that depth. This rectangular model assumes vertical walls and a level, uniform fill.

Keep quotes comparable.

All options cover the same required volume, including your chosen reserve. We round purchases up and keep unknown fees visible. Product suitability still needs your judgment.
