Soil Calculator

Soil — it computes soil volume as area × depth and converts it to bags or cubic yards/metres. This page runs that same calculation on your numbers, in your browser: no signup, no uploads, nothing stored.

Soil Calculator lets you estimate soil needed in seconds: enter your length, width and depth for the volume in bags or cubic yards, all worked out locally in your browser.

Enter your values and tap Calculate.

Estimate only. Volume and weight depend on the area and depth you enter and on the material's density, moisture, settling and compaction, so round up when ordering.

About this calculator

It computes soil volume as area × depth and converts it to bags or cubic yards/metres. It matters before you buy: a clean volume estimate plus a waste allowance beats a guess every time. Here is the calculation on real numbers: A raised bed 2 m × 1 m × 0.3 m needs 2 × 1 × 0.3 = 0.6 m³ of soil. For your own figures, use the calculator above — same method, your inputs, computed on-device.

How to use

  1. Enter the area length in feet.
  2. Enter the area width in feet.
  3. Enter the soil depth in inches.
  4. Tap Calculate to see volume, bag count, and approximate weight.

Why use the Soil Calculator

Instant

Every quantity is worked out on your device the moment you tap Calculate.

Private

The numbers you enter stay in your browser and are never uploaded or saved.

Free

No signup, no paywall, and no ads placed inside your results.

Works offline

Once the page has loaded it keeps working on a weak or dropped connection.

Mobile-first

Laid out for phones and tablets on site just as much as for desktops.

Planning estimates

Results are simplified planning estimates; real material needs vary by product size, waste, layout, local codes, and site conditions, so confirm before you buy or build.

Common uses

Use it when reducing over-ordering

Use it for estimating soil, mulch or gravel volume

Use it when filling a bed or area to a depth

Use it when ordering by cubic yard or metre

Use it when budgeting a landscaping job

Use it for outdoor and yard work

Technical notes

Soil Calculator computes soil volume as area × depth and converts it to bags or cubic yards/metres.

A volume estimate from the dimensions you enter; allow for settling, compaction or spillage and round up when ordering.

All arithmetic runs in your browser using double-precision floating point, so extreme inputs may show tiny rounding differences.

Worked example

A raised bed 2 m × 1 m × 0.3 m needs 2 × 1 × 0.3 = 0.6 m³ of soil.

FAQ

How is topsoil volume worked out?

Length times width times the depth in inches converted to feet gives cubic feet, then cubic yards.

Does the Soil Calculator keep my entries private?

Yes. The Soil Calculator runs in your browser, so nothing you enter is uploaded or saved.

How is the weight estimated?

Cubic yards are multiplied by about 1.08 tons, though moisture and soil type change the real weight.

How big is a soil bag here?

Small bags are taken as 0.75 cubic feet, and the bag count is rounded up.
