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.
What It Calculates
- Total area and volume (m²/ft², m³/yd³)
- Adjusted volume with compaction and waste
- Total mass (tonnes / short tons)
- Bag counts (20 kg, 40 kg, 50 lb) and 1-tonne bulk bags
- Approx wheelbarrow loads and common truckload equivalents
Typical Densities (Editable)
- Pea gravel: ~1550–1600 kg/m³
- Crushed stone 20 mm: ~1600–1750 kg/m³
- Road base (compacted): ~1800–1950 kg/m³
- River rock: ~1550–1650 kg/m³
- Masonry sand: ~1450–1600 kg/m³

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.

Important Estimate Disclaimer
These calculations are general planning estimates only. Actual aggregate quantities may vary due to compaction rates, settlement, moisture content, and excavation depth.
See our Methodology and Data Sources for details.
Base preparation, drainage requirements, and load-bearing needs may alter total material requirements.
