Asphalt Calculator

Estimate how much asphalt you need for a driveway, parking pad, private lane, overlay, or patch. The calculator uses compacted thickness, density, waste, and local price inputs so the result is closer to a real order quantity.

Calculator

Asphalt Tonnage and Cost Calculator

Use this for hot mix asphalt, warm mix asphalt, cold mix, or recycled asphalt millings.

Project Inputs

Use compacted thickness for finished asphalt depth.

When to use this calculator

Use this page when you know the rough dimensions of the paved area and need a planning estimate before ordering material or comparing contractor numbers.

What changes the estimate

  • Finished compacted thickness, not loose lift thickness.
  • Material density, especially when comparing hot mix asphalt and millings. See asphalt millings vs gravel if you are weighing a budget surface.
  • Waste allowance for odd shapes, edges, and delivery variation.
  • Base prep, drainage, removal, and access for trucks and rollers.

Formula

area_sq_ft * (compacted_thickness_inches / 12) * density_lb_per_cu_ft / 2000

These are planning estimates. Confirm local material density, supplier tickets, contractor scope, drainage, base condition, and local code before buying material or signing a contract.

FAQ

Asphalt Calculator FAQ

How do I calculate asphalt tons?

Multiply square feet by compacted thickness in feet, multiply by density in pounds per cubic foot, then divide by 2,000. Add waste for ordering.

What density should I use for asphalt?

For early planning, 145 lb/ft3 is a common hot mix asphalt value. Supplier mix designs can vary, so confirm the density when ordering.

Should I include waste?

Yes. For most driveway projects, 5% to 10% waste is a practical planning range. Small patches and irregular shapes may need more.
