Terms of use

What the site is

Gravel Calculator Online is a free tool for estimating gravel and stone quantities. You do not need an account to use it, and you can use it for personal or business projects.

Estimates, not advice

The results are planning estimates based on the numbers you enter. They are not engineering, drainage, structural or legal advice. Confirm quantities, densities, prices and delivery terms with your supplier, and follow your plans, the manufacturer's instructions and local rules.

No warranty

The site is provided as is. We work to keep the math correct and the site available, but we do not guarantee either. We are not responsible for the cost of over- or under-ordering, or for any loss that comes from relying on an estimate.
