How much asphalt a driveway takes
A driveway's asphalt tonnage is its area times the compacted thickness times the weight of the mix. Minnesota's transportation department estimates hot-mix quantities with 113 lb per square yard for each inch of thickness, which works out to about 150.7 lb per cubic foot; its shortcut is square yards × inches × 0.0565 = tons.[1]
Tons = sq yd × inches × 0.056566.7 sq yd × 3 × 0.0565 = 11.3 tons
| Driveway | Area | 2 in | 3 in | 4 in |
|---|---|---|---|---|
| 10 × 20 ft | 200 sq ft | 2.5 | 3.8 | 5.0 |
| 12 × 30 ft | 360 sq ft | 4.5 | 6.8 | 9.0 |
| 12 × 50 ft | 600 sq ft | 7.5 | 11.3 | 15.1 |
| 16 × 40 ft | 640 sq ft | 8.0 | 12.1 | 16.1 |
| 20 × 40 ft | 800 sq ft | 10.0 | 15.1 | 20.1 |
| 24 × 24 ft | 576 sq ft | 7.2 | 10.9 | 14.5 |
Mixes differ in weight, so if your supplier gives a different figure, change the weight field. Thickness and base depth come from your contractor's specification or your town's driveway standard; this page does not assume one.
Price per square foot or per ton?
Paving bids come either way, and the calculator accepts both: per square foot multiplies the area, per ton multiplies the tonnage. To compare a per-ton bid with a per-square-foot bid, convert with the coverage of a ton: at 3 inches, one ton covers about 53.1 sq ft. A new gravel base, removal of the old surface, edging and any permit are separate lines.
Driveway costs in national data
Homeowners did about 4.6 million driveway and walkway jobs in the two years to 2023; the median cost was $2,914 and the average $5,032.[2] That category covers every material and walkways too. On new homes, the builders' 2024 survey put the driveway at $9,635 on average, about 2.3% of construction cost.[3] NAHB's life-expectancy study gives an asphalt driveway 15 to 20 years, as a general guideline.[4]
Worked example
- Area: 50 × 12 = 600 sq ft, or 66.7 sq yd.
- Volume at 3 in: 600 × 3 ÷ 12 = 150 cu ft (5.56 cu yd).
- Weight: 150 × 150.7 lb ÷ 2,000 = 11.3 tons.
- Cost: 600 sq ft × your price per sq ft, or 11.3 tons × your price per ton, plus base, removal and edging.

Paying for a new driveway
Paving the driveway of the home you live in can be a substantial improvement for tax purposes when it adds value, which matters if you borrow against the house: interest on home equity debt is deductible only when the money buys, builds or substantially improves that home.[5] The CFPB's home equity guide reminds owners that missing payments on a loan secured by the house can lead to foreclosure.[6] For a project this size, compare a loan, a HELOC and cash in the home improvement loan calculator; if the driveway is part of a larger exterior job, the gutter installation cost calculator and roof replacement cost calculator cover the house.
Frequently asked questions
Can I use this driveway cost calculator for concrete or gravel?
The area and the cost per square foot work for any surface: enter the price per square foot from a concrete or gravel quote. The tonnage figures are for hot-mix asphalt only, because they use asphalt's density. For measuring an odd-shaped driveway, use the square footage calculator.
How many tons of asphalt do I need for a driveway?
Square yards × inches of thickness × 0.0565, using Minnesota DOT's 113 lb per square yard per inch.[1] A 50 × 12 ft driveway at 3 in is about 11.3 tons.
How much does an asphalt driveway cost?
Your area or tonnage times your contractor's price, plus base and removal. For scale, homeowners' driveway and walkway jobs had a median cost of $2,914 in the 2023 American Housing Survey, across all materials.[2]
How long does an asphalt driveway last?
About 15 to 20 years in the NAHB life-expectancy study, which it calls a general guideline.[4] Drainage, base quality and sealing affect it.
How many square feet does a ton of asphalt cover?
About 79.6 sq ft at 2 in, 53.1 sq ft at 3 in and 39.8 sq ft at 4 in, at 113 lb per square yard per inch.
