Contact Dirt Calculator

Include the exact inputs: each area's shape and dimensions in feet, the material you selected, the compaction buffer preset, the truck and bag sizes, and any price per yard or ZIP code you entered — plus the result you expected versus the one shown. A screenshot of the calculator panel with your values filled in usually lets us reproduce and explain the difference in a single reply.

Not yet. Email lets us rebuild your calculation by hand and verify every answer against the shape geometry, the eleven-material density table, and the coverage chart before responding — which matters when the topic is an order a truck is about to deliver. We read every message and answer most within two business days.

We can tell you what the calculator's method says for the inputs you enter — and show every step behind it, from shape volume to buffered order quantity. But a real site has real conditions: depth that varies across the dig, loose-versus-compacted volume, and the settlement of whatever the fill sits on. Treat the computed yardage as the strong hypothesis and confirm it with the tape measure and your supplier before the truck is booked.

Suppliers quote loose delivered yards and apply their own shrinkage rules of thumb — some assume ten percent, a few assume twenty-five for clay. Two figures for the same dig can differ by a full truckload and both be defensible under the assumptions each made. Compare the base volume, the buffer, and the density behind each number before comparing prices — the discrepancy is almost always in the assumptions, not the arithmetic.

No. The site sells nothing, carries no affiliate links to any supplier, hauler, or marketplace, and is not affiliated with any brand. Advertising is clearly labeled and separately handled — see the advertising section of the Privacy Policy for how that works.

Please do — that is how the toolset grows. Send the problem you were trying to solve, the site you were working with, and what you wished had been calculated for you. Requests that describe a real order or a real quote — 'can you add crushed gravel densities?' or 'can I mix two materials in one project?' — go to the top of the content queue.

Only for as long as your thread is open. Whatever you include — inputs, screenshots, the result you expected — is used to reproduce the calculation and fix whatever you reported, then it is deleted. Your address is never added to a mailing list, because there is no mailing list, and nothing you send is shared with third parties.

Yes — that is planning use, and it is what the tools are for. Run your own inputs, treat the output as your working figure, and verify it against the site conditions and the supplier's ticket before committing. What you may not do is present the output as an engineered grading plan or a stamped specification — the Disclaimer covers the line in detail.
