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
The results provided by this calculator are intended as general estimates only and should not be considered precise engineering measurements. Actual material requirements, costs, and quantities can vary significantly based on site conditions, local building codes, soil type, reinforcement requirements, climate exposure, and the intended use of your project.
These calculators are designed to help you plan and budget your project more effectively, but they do not replace professional advice from a qualified contractor, engineer, or building inspector. Always verify your calculations and assumptions with trained professionals before placing material orders or commencing construction.
For more information on the assumptions, formulas, and data used in these tools, see our Data Sources and Methodology pages.
Material estimates, cost figures, and volume calculations are approximate and may not reflect your actual requirements. Always double-check dimensions and project-specific needs, and consider adding a contingency allowance for waste, over-excavation, and unforeseen conditions.
If you are unsure about any aspect of your project — including structural requirements, reinforcement needs, drainage, or load-bearing capacity — consult with a licensed professional before proceeding.
