How to use this calculator
- 01Enter the measured area and compacted depth.
- 02Use a supplier density or keep the editable planning value.
- 03Add an allowance and compare the result with supplier load sizes.
Assumptions and limitations
What the estimate assumes
- Depth is uniform after compaction.
- Entered tons-per-cubic-yard density matches the supplied material.
- Weight is calculated from loose order volume.
What it does not determine
- Actual density and compaction vary widely.
- Subgrade excavation, geotextile, and base layering are outside this calculation.
- Confirm load limits, access, drainage design, and underground services before work.
Frequently asked questions
Why can I edit gravel density?
Different aggregates have different weights. A supplier-provided tons-per-cubic-yard value produces a better estimate.
Is depth compacted or loose?
Enter the desired finished compacted depth. The allowance can help cover compaction and handling, but it is not a compaction engineering model.
Does this replace supplier advice?
No. Confirm the aggregate specification, density, minimum order, and delivery constraints with the supplier.
