How the soil volume calculator works

Soil volume:
The calculator multiplies length, width, and depth to estimate cubic feet, then converts to cubic yards.

Field application:
If field acres are entered, the calculator estimates soil volume from acres and application depth.

Soil tons:
Cubic yards are multiplied by bulk density to estimate total tons.

Bags and cost:
The calculator estimates bags needed, bulk soil cost, bagged soil cost, delivery fee, and total project cost.

Why use a soil volume calculator?

A soil volume calculator helps estimate how much soil, topsoil, compost, or fill material is needed before ordering.

It can help compare cubic feet, cubic yards, tons, bag count, bulk delivery cost, bagged cost, field application depth, and amendment mix.

What your result means

Your result shows estimated soil volume in cubic feet and cubic yards, soil tons, bags needed, bulk cost, bagged cost, delivery cost, total project cost, and compost or amendment mix volume. These are estimates based on the values you enter.

Soil volume formulas

Frequently asked questions

How do you calculate soil volume?

Multiply length by width by depth in feet. If depth is measured in inches, divide by 12 first. Divide cubic feet by 27 to convert to cubic yards.

How many cubic feet are in a cubic yard of soil?

One cubic yard equals 27 cubic feet.

How do you calculate bags of soil needed?

Divide total cubic feet needed by the bag size in cubic feet. For example, 30 cubic feet divided by 1.5 cubic foot bags equals 20 bags.

Why add waste or settling?

Soil can settle after watering, spreading, grading, or compaction. Extra material helps cover uneven ground, spillage, and settling.
