What does an asphalt tonnage calculator include?

It converts area and thickness into US tons (and often cubic yards), optionally adds waste, and can estimate material cost. Use compacted HMA density unless you are ordering millings or cold mix.

How do I use an asphalt calculator square feet to tons?

Enter square footage and thickness, or use tons = sq ft × inches ÷ 162. Example: 1,000 sq ft at 3 inches ≈ 18.5 tons before waste.

How do I calculate asphalt millings?

Same volume math as asphalt, but use ~1.49 tons per cubic yard. Millings are lighter and usually cheaper ($10–$25/ton) than hot mix.

How do I calculate asphalt yield?

Yield is sq ft covered per ton. At typical HMA density: ~80 sq ft/ton at 2 inches and ~54 sq ft/ton at 3 inches.

How do I calculate asphalt sealcoating?

Estimate gallons from coverage rates (about 40–60 sq ft/gal first coat, 60–80 second). A 1,000 sq ft driveway often needs ~30–35 gallons for two coats.

How do I calculate cold patch asphalt?

Measure the repair cavity volume, convert to cubic yards, then apply cold-mix density (~1.76 tons/cu yd). Small potholes are often ordered in bags by the pound.

Asphalt Tonnage Calculator Guide: Sq Ft to Tons, Millings & Yield

Quick answer

An asphalt tonnage calculator estimates US tons from area × thickness. For hot mix: tons = sq ft × inches ÷ 162. Use lower density for millings (~1.49 tons/cu yd). Run numbers in the free asphalt calculator.

Asphalt tonnage calculator basics

Searchers looking for an asphalt tonnage calculator, asphalt ton calculator, or asphalt calculator tons want the same output: how many US tons to order. The calculator on this site also shows cubic feet / cubic yards so you can cross-check plant tickets and truck loads.

Tons (HMA) = Square feet × Thickness (in) ÷ 162

Asphalt calculator square feet to tons

When you already know square footage (from a survey, CAD takeoff, or the square footage calculator), skip length/width and go straight to tons.

Thickness	Tons per 1,000 sq ft	Sq ft per ton
1 in	6.2	160
2 in	12.3	80
3 in	18.5	54
4 in	24.7	40

Asphalt millings calculator

Recycled asphalt millings (RAP) use the same volume formula but a lighter density. Example: 500 sq ft at 4 inches → 6.17 cu yd × 1.49 ≈ 9.2 tons. Millings suit budget driveways and base layers; they are not a drop-in replacement for structural hot mix in every climate.

Convert cu yd ↔ tons with cubic yards to tons.

Asphalt volume, yield, and spread rate

Volume is cubic yards before weight. Yield is area covered per ton. Spread rate is lb per square yard. At 3 inches and 145 lb/cu ft, spread rate is about 326 lb/sq yd.

Step-by-step tonnage math: how to calculate asphalt tonnage.

Asphalt sealer & cold patch calculators

Sealcoat is sold by the gallon, not the ton — estimate from coverage rates, not the HMA ÷162 formula. Cold patch uses cavity volume × cold mix density. Both workflows are covered on the asphalt calculator page sections.

Parking lots and paving cost

Larger paving jobs use the same tonnage math; cost is often quoted per square foot installed. For driveway pricing bands and asphalt vs concrete, see the asphalt driveway cost guide. For base stone under asphalt, use the gravel calculator.
