Asphalt tonnage calculator (free asphalt ton calculator)
Free asphalt tonnage calculator for driveways, parking pads, and paving jobs. Enter length, width, and thickness to estimate how many tons of hot mix asphalt to order.
How to calculate asphalt tonnage
Asphalt is ordered by the ton. This asphalt calculator converts your paved area and thickness into cubic feet, multiplies by compacted density, and divides by 2,000 to get US tons. Full details are on our methodology page.
Formula: Tons = Length (ft) × Width (ft) × (Thickness in inches ÷ 12) × Density (lb/ft³) ÷ 2000. Then add waste (often 5–10%) for edges and waste.
- Driveway asphalt calculator: use your driveway length and width, typical thickness 2–3 inches — or open the dedicated driveway tool.
- Hot mix asphalt density: ~140–150 lb/ft³; 145 is a common planning default — confirm with your plant.
- Asphalt cost calculator: enter your local price per ton for a material-only estimate (not labor or prep). Planning ranges: asphalt cost per ton.
- Base stone: estimate crushed stone under the asphalt with the asphalt base calculator.
- Trap rock: estimate dense crushed trap rock for gravel drives with the trap rock driveway calculator.
- Rainfall runoff: estimate roof and driveway storm gallons with the roof runoff calculator and driveway runoff calculator (planning only).

Asphalt calculator FAQ
How many tons of asphalt do I need?
Multiply area (ft²) by thickness in feet (inches ÷ 12), multiply by density (often 145 lb/ft³), divide by 2,000. Add 5–10% waste. This tool does that instantly. See size examples on how many tons of asphalt.
How thick should driveway asphalt be?
Many residential driveways use about 2–3 inches of compacted hot mix over a proper base. Follow your contractor or local specs.
Does this include labor cost?
No. Cost per ton here is material only. Full job cost also includes prep, base, labor, haul, and tax.
Is AsphaltTons.com free?
Yes. No signup. Estimates are for planning — confirm density, truck minimums, and pricing with your supplier.
