When planning an asphalt paving project—whether it’s a driveway, parking lot, or road—one of the most critical steps is calculating the required materials and costs. An asphalt calculator simplifies this process, helping you determine the exact tonnage, volume, and total cost of your project.
Why Use an Asphalt Calculator?
Estimating asphalt needs manually can be complex, involving conversions between square feet, cubic yards, and tons. Mistakes can lead to overordering (wasting money) or underordering (delaying your project). A reliable asphalt tonnage calculator eliminates guesswork by considering:
✅ Dimensions (length, width, depth)
✅ Material density (hot mix asphalt vs. millings)
✅ Unit conversions (imperial or metric)
✅ Cost per ton (local pricing fluctuations)
Key Features of Our Asphalt Calculator
Our free online tool supports:
- Imperial & Metric Units (feet, meters, tons, kg)
- Multiple Shapes (rectangular, circular, triangular)
- Cost Estimation (adjustable price per ton)
- Recycled Asphalt (RAP) Calculations
- Comparison Tool: Asphalt vs. Concrete Driveway Cost
How to Calculate Asphalt Tonnage
The formula used in most asphalt calculation tools is:
Tonnage = (Length × Width × Depth × Density) / 2000
Where:
- Length & Width in feet
- Depth in inches (convert to feet by dividing by 12)
- Density of hot mix asphalt ≈ 145 lbs/ft³ (varies by mix)
Example Calculation:
For a 20 ft × 30 ft driveway at 3 inches deep:
- Convert depth: 3 in ÷ 12 = 0.25 ft
- Volume: 20 × 30 × 0.25 = 150 ft³
- Weight: 150 × 145 = 21,750 lbs
- Tons: 21,750 ÷ 2000 = 10.875 tons

Asphalt Driveway Cost Calculator
The cost of an asphalt driveway depends on:
- Thickness (2-3 inches for residential, 4+ for heavy traffic)
- Base preparation (gravel subbase adds cost)
- Local material prices (typically $100–$200 per ton)
- Labor & equipment fees
Our asphalt driveway cost calculator factors in these variables, giving you a realistic budget estimate.
Asphalt vs. Concrete Driveway Costs
| Factor | Asphalt | Concrete |
|---|---|---|
| Cost per sq.ft | $3–$7 | $6–$12 |
| Lifespan | 15–20 years | 30+ years |
| Maintenance | Reseal every 3–5 years | Less frequent, but cracks harder to repair |

FAQs About Asphalt Calculations
How many square feet does a ton of asphalt cover?
At 2 inches thick, 1 ton covers ~80 sq.ft. At 3 inches, it drops to ~54 sq.ft.
How do you calculate asphalt for irregular shapes?
Break the area into rectangles/triangles, calculate each, then sum the totals.
Does cold weather affect asphalt calculations?
Yes! Cold mix asphalt has different compaction rates—our cold patch asphalt calculator adjusts for this.
