Use the asphalt calculator to estimate how much asphalt (tarmac) you need to pave a driveway, schoolyard, sidewalk, road or parking lot. Our asphalt calculator helps you accurately estimate the volume (cubic feet, cubic yards or cubic meters), weight (tons or tonnes) and cost of asphalt needed for your project. Whether you're a contractor or DIY home renovator, this free tool provides fast, reliable results in seconds.
This asphalt calculator uses US/metric units and takes into account area dimensions, thickness and material density to calculate asphalt tons or cubic yards. Save time, reduce waste and complete your project within budget with our calculator.
Asphalt Calculator
Estimate the volume, weight, and cost of asphalt for your project.
Formula Used in Asphalt Calculator
- Volume (cubic feet) = Length × Width × Thickness (in feet)
- Weight (tons) = Volume × Asphalt Density / 2000
Density of hot mix asphalt (HMA) is usually 145 lb/ft³.
Example Calculation
Let’s say you want to cover a 30-foot long and 20-foot wide driveway with 3 inches of asphalt:
- Convert 3 inches to feet = 0.25 ft
- Volume = 30 × 20 × 0.25 = 150 ft³
- Weight = 150 × 145 / 2000 = 10.875 tons
FAQ's on Asphalt Calculator
