Asphalt Calculator: Volume, Weight & Cost Estimator

Get accurate estimates for your asphalt paving project with our free calculator. Simply enter your dimensions to calculate volume, weight, and total cost. Works for driveways, roads, parking lots, and more.

Select Unit System

Metric (meters, kg) Imperial (feet, lbs)

Enter Dimensions

Width:

Example: 4 meters / 13 feet

Length:

Example: 15 meters / 50 feet

Depth:

Example: 0.1 meters / 0.33 feet (4 inches)

Tip: Standard driveway asphalt depth is typically 2-4 inches (0.05-0.1 meters).

Optional: Price per Ton

Price ($):

Example: $75-150 per ton (varies by location)

Advanced Options (Optional)

Custom Density Factor:

Default: 2.4 tons/m³ (metric) or 2.2 tons/yd³ (imperial)

Wastage Percentage:

Recommended: 5-10% to account for potential waste

Conversion Info: 1 cubic yard = 27 cubic feet | 1 inch = 0.0833 feet | 1 foot = 0.3048 meters

Calculation Results

Required Asphalt Volume: 0 cubic yards

Total Weight: 0 tons

Note: These calculations are estimates. Always consult with a professional contractor for precise project requirements.

How to Use the Asphalt Calculator

Select Unit System: Choose between Metric or Imperial units based on your preference.
Enter Dimensions: Measure and input the width, length, and depth of your project area accurately.
Optional Price Input: Enter the current price per ton of asphalt in your area to estimate the total cost.
Advanced Options: For more precision, enter a custom density factor if you know the specific density of your asphalt mix. Add a wastage percentage to account for spillage and compaction.
Calculate: Click the 'Calculate' button to instantly view your required asphalt volume, weight, and cost estimates.

Important: For large projects, we recommend getting a professional assessment as soil conditions, drainage requirements, and other factors may affect material needs.

How to Calculate Asphalt Tonnage for Driveways

Calculating the correct amount of asphalt for your driveway is essential for accurate budgeting and project planning. Follow these steps:

Measure your driveway dimensions (width and length) in feet or meters.
Determine the desired depth - typically 2-4 inches (0.05-0.1 meters) for residential driveways.
Use our calculator above to get an accurate tonnage estimate based on these measurements.
Add 5-10% extra for wastage and compaction (already factored in if you used the wastage field).

Typical residential driveway estimates:

Single-car driveway (10ft × 20ft × 3in): Approximately 3 tons
Double-car driveway (20ft × 20ft × 3in): Approximately 6 tons
Long driveway (12ft × 50ft × 3in): Approximately 9 tons

Pro Tip: For areas with heavy vehicle traffic or in cold climates, consider increasing the depth to 4 inches for better durability.

Climate Performance	Better in cold climates	Better in hot climates

Frequently Asked Questions

How do I use the Asphalt Calculator?

Select your preferred unit system (metric or imperial), enter your project dimensions (width, length, and depth), add the price per ton if you want to calculate costs, and click the 'Calculate' button. The results will show the volume, weight, and estimated cost instantly.

Is the calculator suitable for both metric and imperial units?

Yes, our calculator supports both measurement systems. Simply select your preferred option at the top of the form. For metric, enter dimensions in meters to get results in cubic meters and tonnes. For imperial, enter dimensions in feet to get results in cubic yards and tons.

How much does asphalt cost per ton in 2025?

As of 2025, asphalt costs typically range from $75 to $150 per ton, depending on your location, oil prices, and market conditions. Urban areas tend to have higher prices compared to rural locations. For the most accurate pricing, contact local suppliers for current rates.

How deep should my asphalt be?

The recommended asphalt depth depends on the intended use:

Residential driveways: 2-3 inches (5-7.5 cm)
Commercial driveways: 3-4 inches (7.5-10 cm)
Parking lots: 3-4 inches (7.5-10 cm)
Roads with light traffic: 4-5 inches (10-12.5 cm)
Roads with heavy traffic: 5-6+ inches (12.5-15+ cm)

These depths typically refer to the compacted asphalt layer over a properly prepared base.

How accurate is this calculator?

Our calculator provides highly accurate estimates based on the dimensions and density values you enter. For even more precision, use the Advanced Options to customize the density factor and account for wastage. However, actual material needs may vary based on site conditions, compaction rates, and other project-specific factors.

Asphalt vs Concrete Cost: Which is better?

Asphalt is generally more cost-effective, with prices 40-60% lower than concrete. Asphalt typically costs $2-$5 per square foot installed, while concrete costs $4-$8 per square foot. Asphalt installation is also faster (1-2 days vs 3-7 days for concrete), and it can be used within 48 hours, while concrete requires 7+ days to cure. However, concrete generally lasts longer (20-30 years vs 15-20 years for asphalt).
