The basics
An asphalt calculator estimates how much asphalt you need for a paving job. You enter the length, width, and thickness of your area, and it returns the volume in cubic yards, the weight in tons, and the material cost. It works for driveways, parking lots, roads, and pothole repair.
Getting the number right matters. Order too little and your crew stops mid pour. Order too much and you pay for asphalt that gets hauled away. This tool gives you a solid figure so you can budget, compare supplier quotes, and avoid both.
Asphalt is the most common paving material in the country, from highway lanes to the driveway in front of your house.
Roughly 94% of paved roads in the United States are surfaced with asphalt.
Step by step
To find how much asphalt you need, multiply length by width by thickness to get the volume, then multiply the volume by the density of asphalt to get the weight. Most hot mix asphalt weighs about 145 pounds per cubic foot, so a 10 foot by 20 foot driveway at 3 inches thick needs roughly 3.6 tons.
Record the length and width in feet. For an odd shape, break it into simple rectangles, measure each one, and add them together.
Most residential driveways use 3 inches of compacted asphalt. Parking lots and heavier traffic use 4 inches or more.
Divide the inches by 12. So 3 inches becomes 0.25 feet.
Multiply length times width times thickness in feet. A 10 by 20 driveway at 0.25 feet is 50 cubic feet.
Multiply the cubic feet by 145 pounds, then divide by 2,000. That 50 cubic feet becomes 7,250 pounds, or about 3.6 tons.
Add 5% to 10% for compaction and spillage so you do not come up short.
The calculator does all six steps the moment you type your numbers in, including the waste allowance, so you get tons, cubic yards, and cost together.
Run my numbers ↑The math
Volume (cubic feet) = length (ft) × width (ft) × thickness (ft)
Weight (tons) = (volume × 145 lb per cubic foot) ÷ 2,000
Real density runs from about 142 to 148 pounds per cubic foot depending on the mix design (Superpave, Marshall, or a state DOT specification) and how well the layer is compacted, so 145 is the accepted middle value used across the paving industry. If you know the exact density of the mix your supplier sells, you can enter it in the tool for a tighter estimate.
A quick note on mix design. Modern hot mix asphalt in the US is usually designed under Superpave, developed by the Strategic Highway Research Program. The binder is graded by Performance Grade (PG), for example PG 64-22, which describes the temperature range the binder holds up in. Your supplier will name the mix and PG grade on the ticket. Match that grade to your climate for the longest life.
The industry standard density for compacted hot mix asphalt is 145 pounds per cubic foot.
If you measure in meters instead of feet, use the same formula with metric density: volume (m³) × 2,322 kg per m³ = weight in kilograms, then divide by 1,000 for tonnes. A 3 meter by 6 meter driveway at 75 mm thick needs about 3.14 tonnes of hot mix asphalt. The calculator switches to metric with one toggle, so you do not have to convert by hand.
Coverage
One ton of hot mix asphalt covers about 83 square feet at 2 inches thick, or about 55 square feet at 3 inches thick. Coverage drops as thickness goes up, because a thicker layer uses more material over the same area. The table below shows the coverage for common driveway and lot thicknesses, based on 145 pounds per cubic foot.
| Thickness | Coverage per ton | Common use |
|---|---|---|
| 1 inch | about 165 sq ft | Thin overlay, top coat |
| 2 inches | about 83 sq ft | Light residential, resurfacing |
| 3 inches | about 55 sq ft | Standard driveway |
| 4 inches | about 41 sq ft | Heavy driveway, light parking lot |
| 6 inches | about 28 sq ft | Commercial lot, truck traffic |
At 3 inches compacted, one ton of hot mix asphalt covers about 55 square feet.
Read it the other way when you plan a job. A 550 square foot driveway at 3 inches needs about 10 tons, since one ton covers roughly 55 square feet at that depth.
Pricing
Hot mix asphalt typically costs $100 to $150 per ton in 2026, though the price moves with crude oil and changes by region and how far the material has to travel from the plant. Cold mix for patching and specialty mixes can cost more. The calculator turns your tonnage into a material cost the moment you enter a price per ton.
These figures cover the asphalt material only, at 3 inches compacted, using a mid range price of $100 to $150 per ton. They do not include labor, base preparation, or delivery, which vary by contractor and site.
| Driveway size | Approx. area | Asphalt needed | Material cost |
|---|---|---|---|
| Small (10 × 20) | 200 sq ft | about 3.6 tons | $360 to $540 |
| 2 car (20 × 20) | 400 sq ft | about 7.3 tons | $725 to $1,090 |
| Wide (20 × 40) | 800 sq ft | about 14.5 tons | $1,450 to $2,175 |
| Large (1,000 sq ft) | 1,000 sq ft | about 18 tons | $1,810 to $2,720 |
| Extra large (2,000 sq ft) | 2,000 sq ft | about 36 tons | $3,630 to $5,440 |
Prices vary by region because plants are not evenly spread and hauling distance is expensive. The table below is a working 2026 range based on published supplier quotes and industry reports. Our own survey (see the price index section below) will replace these figures with fresh, verified numbers.
| US region | Typical range per ton (2026) | Notes |
|---|---|---|
| Northeast | $110 to $160 | Higher labor and short paving season |
| Mid-Atlantic | $105 to $145 | Steady demand from municipal work |
| Southeast | $95 to $135 | Long paving season, competitive supply |
| Midwest | $100 to $140 | Freeze thaw drives more repave work |
| Great Plains | $105 to $145 | Longer hauling distances in rural areas |
| Southwest | $100 to $140 | Heat-graded binders add cost |
| Mountain West | $115 to $165 | Remote plants, limited paving window |
| Pacific Northwest | $110 to $155 | Rainy season shortens jobs |
| California | $115 to $170 | Strict CalTrans specs and emissions rules |
| Alaska and Hawaii | $180 to $260 | Shipping and limited supply |
Different mixes cost different amounts. Hot mix is the standard; specialty mixes cost more per ton but suit specific jobs.
| Asphalt type | Typical cost per ton (2026) | Best use |
|---|---|---|
| Hot Mix Asphalt (HMA) | $100 to $150 | New driveways, parking lots, roads |
| Warm Mix Asphalt (WMA) | $105 to $155 | Cooler weather jobs, lower emissions |
| Cold Mix Asphalt | $130 to $200 | Pothole and small repair patches |
| Porous Asphalt | $150 to $220 | Drainage-heavy lots and drives |
| Recycled (RAP mix) | $80 to $120 | Budget residential paving |
Installed cost, with labor and base included, usually runs higher than the material alone. For a full installed estimate on a driveway, use our asphalt driveway cost calculator.
Delivery
Asphalt delivery typically costs $2 to $5 per mile from the plant, with a common minimum charge of $75 to $150 per load. A truckload holds about 20 to 25 tons, so on a residential job the delivery is often bundled with the material price. Expect delivery to add $150 to $400 on a standalone material purchase, more if you are outside the plant's normal service radius.
The calculator has a delivery field so you can add your quoted delivery cost and see the true total for the job.
Rule of thumb #1
Ask the supplier for a delivered price per ton, not just the ton price at the plant, so you can compare quotes on the same basis.
Rule of thumb #2
Confirm the truck type and turning radius. A 22 ton dump truck needs room to back in and dump. If your driveway is tight, ask for a smaller truck or plan on a wheelbarrow transfer.
Materials
The mix you choose changes the weight, the cost, and how long the surface lasts. Here is a plain comparison.
New driveways, parking lots, roads
The standard. Most durable, laid hot, cures fast
Cooler weather jobs
Made at a lower temperature, lower emissions
Pothole and crack repair

Budget residential work
Uses reclaimed asphalt, lower cost
Most homeowners paving a driveway use hot mix. If your whole job is hot mix, our hot mix asphalt calculator gives you a mix specific estimate. If you are filling a pothole yourself, cold mix in a bag is the simpler choice.
Under the asphalt
A residential asphalt driveway needs a compacted crushed stone base of 4 to 8 inches, with 6 inches being the safe middle for most sites. Commercial lots and truck-traffic driveways often use 8 to 12 inches. The base carries the load, so under-building here is where most driveways fail early.
A 20 by 20 driveway at 6 inches of crushed stone base needs about 10 tons of stone. The calculator has a base toggle that computes this alongside the asphalt tonnage, so you can price the whole job in one screen.
Base material types. Class 5 or Class 2 aggregate, or a locally graded crushed stone specified as "3/4 minus" or "dense-graded aggregate base course" (DGABC), all work. Your state DOT spec sheet lists the exact grade for road work; homeowners can use the supplier's standard base grade.
Lifespan
A well built asphalt driveway lasts 15 to 20 years in most US climates, and up to 30 years with strong maintenance. Life depends on four things: mix quality, base preparation, drainage, and sealcoat schedule. Skip any one of those and the surface shortens fast.
Hot mix from a reputable plant beats bag-mix every time.
A 4 to 8 inch compacted crushed stone base carries the load. Under-built base is the top failure cause.
Water pooling on or under the asphalt breaks it down. Slope the surface at least 1/4 inch per foot away from structures.
Seal every 3 to 5 years to protect the binder from UV and water.
Sealcoat a new asphalt driveway 6 to 12 months after installation, once the surface has cured. After that, resealing every 3 to 5 years keeps the binder protected and slows cracking. Sealcoating too early can trap oils in the fresh asphalt and cause soft spots.
Signs it is time to sealcoat again: color has faded from black to gray, fine surface cracks are showing, or water no longer beads on the surface. A quality sealcoat runs $0.15 to $0.30 per square foot applied, or $300 to $600 for a typical 2,000 sq ft driveway.
Compare
If you are still choosing a surface, this is the complete comparison across 12 factors that actually matter for a residential driveway. Asphalt sits in the middle on price and installs the fastest.
| Factor | Asphalt | Concrete | Gravel |
|---|---|---|---|
| Material cost per sq ft | $2 to $5 | $4 to $8 | $1 to $3 |
| Installed cost per sq ft | $7 to $13 | $10 to $20 | $1 to $3 |
| Install time | 1 to 2 days | 1 to 3 days plus curing | Same day |
| Cure to full use | 24 to 72 hours | 7 days minimum, 28 to full strength | Instant |
| Lifespan | 15 to 20 years, up to 30 with care | 25 to 30 years | Ongoing top-ups |
| Freeze thaw performance | Flexes with the ground, holds up well | Cracks in hard freeze thaw cycles | Best performer |
| Hot climate performance | Softens in extreme heat | Excellent | Excellent |
| Maintenance | Sealcoat every 3 to 5 years | Sealer optional; joint work needed | Annual grading, top-up |
| Repair cost | Low (patch or overlay) | High (cut and replace slab) | Very low |
| DIY difficulty | Hard (needs hot material) | Very hard | Easy |
| Resale value impact | Moderate positive | Higher positive | Neutral or negative |
| Best for | Cold climates, fast install, budget | Hot climates, long life, low maintenance | Rural, long drives, tight budgets |
Asphalt flexes with freeze and thaw cycles, which is why it holds up well in northern states where concrete tends to crack. Concrete wins on long-term durability and hot weather. Gravel wins on upfront cost and is common on rural properties where a hard surface is not required.
Why this one
Most tools give you one number. This one shows volume in cubic yards, weight in tons, and total material cost in the same result.
It adds a compaction and waste factor automatically, so your order accounts for real world loss. Ordering short means a second delivery fee of $150 to $400 and a stalled crew.
Enter feet or meters, and handle rectangles, circles, and custom areas without doing the geometry yourself.
Toggle on a crushed stone base and the tool estimates that tonnage too, so you can price the whole job.
Expand the result to see every number used, from your inputs to the final ton value. Nothing hidden. Good for contractor quotes and for teaching yourself the math.
The density values follow the Asphalt Institute MS-2 standard, the cost ranges are cross-referenced against published supplier quotes, and you can check our methodology on the About page.

Original data
Most asphalt pricing pages quote a national range and call it a day. That is not useful if you are pouring a driveway in Michigan and your supplier quotes 20% higher than the national number. We are building a state and region by region index of what hot mix, warm mix, cold mix, and recycled asphalt actually cost this year, based on a quarterly survey of US suppliers.
The first edition is live at Asphalt Price Index once the survey round closes. Until then, the regional table above carries our working ranges from published supplier quotes and industry reports.

FAQ
Direct answers to the questions people ask most about estimating asphalt.
To find how much asphalt you need, multiply length by width by thickness in feet to get the volume, then multiply by 145 pounds per cubic foot and divide by 2,000 to get tons. A 10 foot by 20 foot driveway at 3 inches needs about 3.6 tons. Add 5% to 10% for waste and compaction.
A standard 2 car driveway of about 400 square feet at 3 inches thick needs roughly 7.3 tons of hot mix asphalt. Larger driveways scale up from there, so an 800 square foot drive needs about 14.5 tons. Enter your exact size in the calculator for a precise figure.
One ton of asphalt covers about 83 square feet at 2 inches thick, about 55 square feet at 3 inches, and about 41 square feet at 4 inches. Coverage falls as thickness rises, because a deeper layer uses more material over the same area.
A ton of hot mix asphalt typically costs $100 to $150 in 2026. The price shifts with crude oil, region, and how far the material travels from the plant. Cold mix and specialty mixes can cost more. Ask two or three local suppliers for a current delivered price per ton.
A residential asphalt driveway should be at least 3 inches of compacted asphalt over a 4 to 8 inch crushed stone base. Cold climates and heavier vehicles call for 4 inches or more. Parking lots with truck traffic often use 6 inches or more.
Asphalt tonnage equals length times width times thickness in feet, multiplied by 145 pounds per cubic foot, then divided by 2,000. The 145 figure is the standard weight of one cubic foot of compacted hot mix asphalt. Adjust the density if your supplier gives you a different value.
To convert square yards to tons, first find the area in square feet by multiplying square yards by 9, then multiply by the thickness in feet and by 145 pounds, and divide by 2,000. At 2 inches thick, one square yard of asphalt weighs about 0.24 tons.
Compacted hot mix asphalt weighs about 145 pounds per cubic foot, with real values ranging from roughly 142 to 148 depending on the mix and compaction. A cubic yard, which is 27 cubic feet, weighs close to 3,915 pounds, or just under 2 tons.
A well built asphalt driveway lasts 15 to 20 years in most US climates, and up to 30 years with strong maintenance. Life depends on mix quality, base preparation, drainage, and sealcoat schedule. Under-built base is the top failure cause on residential driveways.
Asphalt delivery typically costs $2 to $5 per mile from the plant, with a common minimum charge of $75 to $150 per load. On a residential job the delivery is often bundled with the material price. Expect delivery to add $150 to $400 on a standalone material purchase.
You can walk on new asphalt after 24 hours and drive a passenger car after 3 days in normal weather. Wait a full 7 to 14 days before parking heavy vehicles or turning the wheels while stopped, because fresh asphalt scars easily. Full cure to maximum strength takes 30 days.
Asphalt and blacktop are the same paving material with different names. Blacktop is a common name for hot mix asphalt used on driveways and small paving jobs. The technical term for the material is asphalt concrete, and it uses a bitumen binder mixed with aggregate. All three terms refer to the same product.
