Crusher Run Quantity Calculator
Calculate crusher-run volume from area and depth, then convert the quantity to tonnes, truck loads and estimated material cost using your actual bulk-density assumption.

Crusher-run quantity formula
For a simple area-and-depth estimate, the geometric volume is the product of area and depth. An allowance is then applied to create a procurement quantity.
Planning volume = volume × (1 + allowance)
Tonnes = planning volume × bulk density
Truck loads = ceiling(tonnes ÷ payload)
Worked example
For 300 m² at 100 mm depth, geometric volume is 30 m³. With a 7% allowance, planning volume is 32.10 m³. At 1.75 t/m³, that is about 56.18 tonnes.
Why placed depth needs definition
Aggregate quantity discussions can mix loose delivery depth with finished compacted depth. The calculator asks you to identify the basis so the result is less likely to be misunderstood.
Density is a procurement input
The same geometric volume can correspond to different tonnages depending on grading and packing. Use supplier bulk-density data when available.
