🪨 Aggregate Calculator

Estimate volume and weight for gravel, crushed stone, road base, sand, and river rock—with depth, compaction, and waste.

Typical depths: paths 2–3 in (50–75 mm), driveways 4–6 in (100–150 mm), drains 6–12 in (150–300 mm).

Editable. Common ranges: 1450–1900 kg/m³ depending on material and moisture.

Extra volume to allow for compacted thickness.

Covers offcuts, irregular edges, spillage.

For small projects—optional.

Aggregate Calculator – Volume, Weight, and Loads

Enter dimensions and depth, choose a material (or set your own density), then apply compaction and waste. The calculator returns volume in metric and imperial, total weight, approximate bags or bulk bags, and estimates for wheelbarrow and truck loads.

FAQs

Should I add compaction?
Yes—bases compact. Add 10–20% so your finished compacted depth matches the design.

How many wheelbarrow loads is that?
A typical contractor wheelbarrow carries about 0.085 m³ (~3 ft³). We’ll estimate loads for convenience.

What density should I use?
Use supplier data if available; otherwise use our presets and adjust for moisture.
