How the gravel driveway calculator works
Estimate the amount of gravel or crushed stone required for a driveway. Enter driveway size, aggregate depth, density and your local price per tonne.
Driveway gravel volume = length × width × depth. Multiply volume by bulk density for an estimated tonnage. The calculator is designed to give a useful first-pass material estimate while keeping the assumptions visible. For a purchase, compare the result with the product packaging or supplier quotation.
