Asphalt Calculator
Calculate tons of hot-mix asphalt, truck loads, and cost for driveways, parking lots, and roads.
Asphalt Needed (with 10% extra)
15.95 tons
1 truck load at 20 tons each
| Area | 1,200 sqft / 133.3 sqyd |
| Volume | 200.0 cubic feet |
| Tons (net) | 14.50 tons |
| With 10% extra | 15.95 tons |
| Truck loads | 1 (20 tons/truck) |
| Estimated cost | $1,595.00 – $2,392.50 |
Mike Callahan:“Order 10% extra on asphalt — once the plant shuts down for the day, you’re done. Running short at 4pm means tearing out and repaving the cold joint tomorrow.”
Methodology
Volume = length x width x (thickness / 12) in cubic feet. Tons = volume x density / 2000. Standard hot-mix asphalt density is 145 lbs per cubic foot. Truck capacity estimated at 20 tons per load. Material cost range of $100-$150/ton represents 2026 national averages for HMA surface course; actual pricing varies by region, mix design, and delivery distance from the plant.

How the asphalt calculator works
The asphalt calculator converts a paving area into tons of hot-mix asphalt, truck loads, and a cost range. You enter the length and width in feet, the thickness in inches, the material density in pounds per cubic foot, and a low and high cost per ton.
The first step is volume. The calculator multiplies length by width by the thickness divided by 12 (to convert inches to feet), giving cubic feet. It then multiplies that volume by the density and divides by 2,000 to turn pounds into tons. Because asphalt compacts and some material is always lost to spillage and an uneven base, the tool adds 10 percent to the net tonnage. Area in square yards is the square footage divided by 9, which is how paving is often quoted. Truck loads are the tonnage-with-overage divided by 20 tons per truck and rounded up. The cost range multiplies the tons-with-overage by your low and high price per ton.
Worked example: a 100-foot by 12-foot driveway at 2 inches thick. Volume is 100 times 12 times 2/12, or 200 cubic feet. At the default 145 pounds per cubic foot, that is 200 times 145 divided by 2,000, which equals 14.5 tons net. Adding 10 percent brings it to about 15.95 tons, which fits in a single 20-ton truck load. The area is 1,200 square feet, or about 133 square yards. At a cost range of $100 to $150 per ton, the material estimate runs from roughly $1,595 to $2,393.
The default density of 145 pounds per cubic foot reflects standard hot-mix asphalt surface course, and the $100 to $150 per ton range reflects 2026 national averages for material only; labor, base preparation, and delivery are separate. Adjust any input to match your mix design, local pricing, and haul distance.
Frequently Asked Questions
How many tons of asphalt do I need?
The calculator finds the volume in cubic feet (length times width times thickness divided by 12), then multiplies by the density and divides by 2,000 to convert pounds to tons. A 100 by 12 foot area at 2 inches thick and 145 pounds per cubic foot works out to 14.5 tons before overage.
Why does it add 10 percent extra?
The tool adds 10 percent to the net tonnage to cover compaction, spillage, and an uneven subgrade. Running short mid-pour means a cold joint and a return trip once the plant reopens, so ordering a little extra is cheaper than coming up short.
What density should I use?
The default is 145 pounds per cubic foot, the standard for hot-mix asphalt surface course. You can adjust it if your mix design differs, but most residential and commercial paving uses a value near 145.
How many truck loads is that?
Truck loads are the tonnage with overage divided by 20 tons per truck, rounded up. The 14.5-ton example becomes 15.95 tons with 10 percent extra, which fits in a single 20-ton load.
