Calculate how much asphalt you need for your driveway or parking lot. Free online asphalt calculator with tonnage and cost estimation.
The asphalt calculator estimates the amount of hot mix asphalt (HMA) needed for paving projects like driveways and parking lots. It calculates volume, tonnage, and provides a rough cost estimate based on average asphalt prices.
Volume (cu yd) = Area × Depth / 27 | Tons = Volume × 1.95 | Cost = Tons × Price/TonHot mix asphalt weighs approximately 1.95 tons per cubic yard (145 lbs per cubic foot). The cost estimate uses an average of $100 per ton, which varies significantly by location and oil prices. Always get local quotes for accurate pricing.
