Soil Calculator

Enter length, width, and depth and this soil calculator returns the fill volume in cubic yards and the same volume in cubic feet.

What this calculator does

The Soil Calculator estimates your result instantly from the values you enter, using standard construction & home formulas. Enter length, width, and depth and this soil calculator returns the fill volume in cubic yards and the same volume in cubic feet. Calculations run in your browser, so nothing you type is sent to a server, and the output is an estimate rather than a certified or official figure.

About Soil Calculator

The Soil Calculator takes a bed's length, width, and depth and reports the fill volume in both cubic yards and cubic feet. Use it to size a bulk soil delivery or compare against bagged volumes.

Formula & Mathematical Calculation

Soil Needed (yd³) = f(Length (ft), Width (ft), Depth (in))

Calculated according to standard construction formulas implemented in the calculator core.

Calculation Example

For an area 20 ft by 10 ft filled 6 in deep, the tool computes 20 x 10 x (6/12) = 100 cubic feet, or 100/27 cubic yards. The Soil Needed (yd³) box shows 3.7 and the Cubic Feet box shows 100.

Key Benefits

  • Converts length, width, and depth into cubic yards of soil
  • Also reports the volume in cubic feet for bagged-product comparisons
  • Takes depth in inches and converts to feet before calculating

How to Use this Calculator

  1. Enter the bed size
    Type the Length (ft) and Width (ft).
  2. Enter the depth
    Type the soil Depth (in).
  3. Calculate
    Click Calculate to read the Soil Needed (yd³) and Cubic Feet boxes.

Assumptions & Limitations

What the calculation assumes

  • Every value you enter is treated as an exact, known amount.
  • Any rate or interval you enter is assumed to hold for the whole period unless the form asks for it separately.
  • Results use standard published formulas and account only for the values entered above.
  • Rounding is applied for display; the underlying calculation uses your full precision.
  • Results are returned in the same units you enter, unless the tool states the output unit.

What it does not cover

  • Soil Calculator produces a calculated result for reference and learning, not a certified or official measurement.
  • Real-world outcomes differ when tolerances, rounding rules or local standards apply.
  • Definitions and standards vary by region and change over time; verify the convention that applies to your case.
  • Figures are only as accurate as the inputs you supply — check them before acting on the result.
  • For work where the result carries real consequences, confirm it against an authoritative source.

Frequently Asked Questions

Both describe the same volume: one in cubic yards (a bulk delivery unit) and one in cubic feet (common for bagged soil). Cubic yards equals cubic feet divided by 27.

No. It reports the exact geometric volume; soil settles once spread, so you may want to order slightly more.

The Depth field expects inches. To enter one foot of depth, type 12.
