Terms of use

Last updated 9 November 2026.

By using Concrete Gravel Calculator you agree to these terms. If you don't agree, please don't use the site.

Using the site

Concrete Gravel Calculator is free to use for personal and work purposes. Please don't try to disrupt the site, scrape it at a rate that slows it down for others, or use it for anything unlawful.

The answers are estimates

The calculators give estimates for planning a purchase. Their weights, bag yields and curing times come from published sources named on each page, but real materials vary: gravel and soil weigh more when wet, weights differ from one pit or brand to another, and the ground is rarely as flat or square as the numbers assume. Prices are typical figures from the date shown and will differ where you buy.

Before you order, confirm the weight per yard, bag yields and prices with your supplier, and add a margin for waste. For structural work, such as footings, retaining walls taller than a garden wall, or anything a building code covers, follow your local code and the advice of a qualified engineer or contractor.

No warranty

The site is provided as it is and as available, without warranties of any kind. It may change, pause or stop at any time.

Liability

To the extent the law allows, we are not liable for any loss or damage that comes from using the site or relying on its content, including the cost of material ordered from its estimates. Nothing in these terms limits a liability that cannot be limited by law.
