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 asphalt calculator

    Enter the finished paving dimensions and the density supplied for the specified asphalt mix. Density is required before a weight can be shown.

    Calculate lifts separately when their mixes or thicknesses differ. The tool does not select a pavement design or compaction method.

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

    A worked example

    With the example values shown below, the calculated result is 0.978 cu yd. These are demonstration inputs, not installation specifications.

    • Length / circle diameter: 12 ft
    • Width: 8 ft
    • Material depth: 3 in
    • Extra allowance: 10 %

    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.

    Asphalt planning questions

    How do I calculate asphalt for a driveway?

    Measure the paved area and the specified thickness of each lift. Calculate lifts separately when the mix or depth changes. This tool measures material volume and optional weight; it does not select the pavement thickness or design the base.

    Can I use the same density for asphalt millings?

    Do not assume the density of a compacted asphalt mix also describes loose recycled millings. Use the density and layer dimensions for the same material state. Supplier advice is needed to relate delivery volume to the finished layer.

    Does the asphalt driveway cost include labor?

    No. The cost fields compare material quantities with the prices and delivery charge you enter. Preparation, removal, machinery, labor, drainage, taxes and minimum-load charges require separate quotes. If your supplier prices asphalt per ton, convert that price to the displayed volume unit using the applicable mix density before entering it.
