Excavation calculator

Find the volume of earth to dig for a pit or trench, how much it swells when dug, and how many loads to carry away.

How it works

Volume = length × width × depth × number of pits. Dug soil takes more space than it did in the ground, so loose volume = volume × (1 + swell %). Swell depends on the soil and truck or trolley capacity differs, so enter your own figures.

Always confirm measurements for a purchase or registration with official records.
