Gravel Calculator

Estimate gravel volume, compacted weight, tons, and delivery.

Measurement guide

Measure the finished footprint and compacted depth; use supplier density for the exact aggregate.

Record each area separately, keep units consistent, and update the estimate with a final site measurement before ordering.

Assumptions and limitations

Density and compaction vary with grading and moisture. The result excludes geotextile, excavation, drainage, and truck capacity.

Prices, tax, and delivery are user-entered planning figures, not supplier quotations.

Worked example

A 12 × 10 ft area at 4 in depth occupies 40 cu ft before compaction; weight follows the selected density and allowance.

Frequently asked questions

What waste allowance should I use?

Simple rectangles often start at 5–10%; complex patterns, many cuts, or fragile material justify more based on the installation plan.

Why is the purchase quantity rounded up?

Packages and whole pieces usually cannot be bought fractionally, so purchasing rounds up while the exact quantity remains visible.

Can I order directly from this result?

Not without verification. Re-measure, check the product label, batch and stock, and confirm with the supplier or a qualified professional.

What does the cost estimate include?

Material cost uses the rounded purchase quantity, then adds entered labor, delivery, and tax; unlisted accessories are excluded.
