Asphalt calculator

Enter paved area, compacted layer thickness and mix density. Add waste and price per metric tonne for an order estimate.

Density and waste are estimates. Use mix data from your supplier. The cost estimate excludes delivery, labor, taxes and other charges.

How much asphalt do I need?

The calculator multiplies area by compacted thickness, then applies the density and optional waste percentage. The example uses 2,400 kg/m³; ask your supplier for the mix density. Cost is based only on the price you enter.

Frequently asked questions

How much asphalt do I need?

The calculator multiplies area by compacted thickness, then applies the density and optional waste percentage. The example uses 2,400 kg/m³; ask your supplier for the mix density. Cost is based only on the price you enter.

Are my measurements uploaded?

No. This calculator runs in your browser and does not send measurements to a server.

What density should I use?

The default density is only an estimate. Replace it with the value from your asphalt supplier; mixtures and compaction vary.

How are extra material and cost estimated?

Extra material is added to the compacted volume before mass and cost are estimated. Cost is tonnes multiplied by your entered price per metric tonne; delivery, labor, taxes and other fees are excluded.
