The calculation

Volume = net area × depth × (1 + extra ÷ 100). Weight = volume × supplier density.

  • Enter your supplier’s bulk density to show weight. Volume alone cannot determine tons.
  • 10% extra is included once. Confirm supplier minimums and delivery increments.

    Measure with a little context

    How to use this aggregate calculator

    Name the aggregate size and intended use when asking for a quote. The term aggregate includes many products with different physical properties.

    This estimates a placed layer; it is not a concrete mix design and does not calculate cement, water or admixtures.

    Volume = net area × depth × (1 + extra ÷ 100). Weight = volume × supplier density.

    A worked example

    With the example values shown below, the calculated result is 1.304 cu yd. These are demonstration inputs, not installation specifications.

    View the example measurements
    • Length / circle diameter: 12 ft
    • Width: 8 ft
    • Material depth: 4 in
    • Extra allowance: 10 %
    • Volume per bag: 0.5 cu ft

    From estimate to order

    Whole packages and pieces round up; measured lengths, areas and volumes keep full precision during calculation. Match the product dimensions and units to your quote, and check cuts, minimum orders and delivery before purchasing.

    Aggregate planning questions

    How do I calculate aggregate base quantity?

    Multiply the covered area by the specified depth for that base layer. Convert to the unit used by your supplier and add an appropriate ordering allowance. If the project uses several aggregate sizes, create one estimate per layer and product.

    Why does the aggregate weight field need a density?

    Aggregate is a broad material category. Stone grading, moisture and whether the material is loose or compacted change its bulk density. The calculator needs the density for your product to convert a volume into meaningful tons or tonnes.
