Cubic Yard Calculator

Use this cubic yard calculator to quickly convert length, width and depth into cubic yards — the standard unit suppliers use to price concrete, gravel, mulch and topsoil. Enter an optional price per cubic yard to get an instant cost estimate for your project.

Concrete Calculator

This concrete calculator estimates how much ready-mix or bagged concrete you need for a slab, sidewalk, pad or footing. It accounts for a waste percentage and converts the total into the three most common bag sizes so you can buy the right amount the first time.

Gravel Calculator

Enter the dimensions of the area you are covering with gravel and this calculator returns both cubic yards (how landscape supply yards price it) and tons (how stone quarries weigh it). Default density is 1.4 tons per cubic yard, typical for crushed stone — adjust for pea gravel or road base.

Asphalt Calculator

Use this calculator to estimate the tons of hot-mix asphalt needed to pave a driveway, walkway or parking pad. It assumes a standard compacted density of 145 pounds per cubic foot, the value most paving contractors quote against.

Mulch Calculator

Mulch keeps roots cool, slows weeds and locks in moisture — but only at the right depth. Enter your bed area and target depth to see how many cubic yards (for bulk delivery) or 2 cu ft bags (for store pickup) you need.

Topsoil Calculator

Whether you are filling a raised bed, leveling a lawn or topping a new install, this topsoil calculator converts your bed dimensions into both cubic yards and tons. Default density is 1.1 tons per cubic yard for screened topsoil — wetter or denser soils run higher.
