Planning estimate only. Verify supplier specifications, local conditions and product suitability before ordering.
Volume = length × width × depth. Weight = volume × bulk density. Price is per US short ton (2,000 lb) in imperial mode, or metric tonne (1,000 kg) in metric mode. Density and settlement vary by material and site; this is not a compaction design.
Gravel Calculator FAQs
How is gravel weight calculated?
Multiply volume by bulk density. The default density is an estimate; your supplier can provide a more accurate figure.
Does the tool account for compaction?
It includes an optional extra allowance but does not calculate engineered compaction requirements.

Frequently asked questions
Are prices live supplier prices?
No. All prices are entered by you; the tool does not fetch local prices or currency exchange rates.
Does changing units change the project size?
No. Existing dimensions are converted to equivalent values when switching between imperial and metric.
Are these engineering calculations?
No. These are preliminary material quantity estimates. Structural design, foundations and local code compliance require appropriate professional review.
Can I share an estimate?
Yes. The share button creates a URL containing the calculator's input values. It does not upload your project data.
