We're a calculator, not a supplier
CalculateGravel doesn't sell, deliver, or quote gravel — we build and maintain the calculator. For an actual gravel order, you need to contact a quarry or landscape supply yard near you. The gravel driveway cost guide covers what to ask suppliers; the cost calculator takes any per-ton or per-yard quote and turns it into a project total.
What we love hearing about
- Errors in our density values or formulas — please include a source if you can.
- Calculator features you wish existed (new shapes, new materials, new project presets).
- Mistakes or unclear sections in our guides.
- Local pricing data — we update our example pricing twice a year.

What we don't do
- Personalized project consulting. The calculator gives you a strong estimate; for engineering or code-compliance questions, talk to a local professional.
- Supplier referrals. We don't take affiliate fees from quarries. We can't recommend a specific supplier in your area.
- Bulk-pricing quotes. Our default prices are illustrative — call your local supplier for current rates.
