Asphalt Calculators | Tonnage, Driveway Cost, Base and Sealcoating

Asphalt tools

Asphalt TonnageMaterialEnter your area and compacted thickness to get the exact tonnage of hot mix asphalt you need — plus cubic yards, truckloads and a delivered cost range.
Driveway CostCostGet an installed price range for a new asphalt driveway, broken down into base prep, paving and extras.
Resurfacing CostCostAn overlay is roughly half the cost of a full replacement — if the existing base is still sound. Price it here.
Replacement CostCostFull tear-out and repave, priced line by line: demolition, disposal, base and new pavement.
Square FootageMeasurementAdd up rectangles, circles and triangles to get the total paving area in every unit contractors quote in.
Thickness & CompactionMeasurementTwo questions, one tool: how deep will my tonnage go, and how much loose mix do I need to hit a compacted depth?
Tons ↔ Cubic YardsMeasurementSuppliers quote tons, plans specify yards. Convert between them for any asphalt or aggregate density.
Gravel BaseMaterialThe base course carries the load — get it wrong and the asphalt above it fails. Size your crushed aggregate here.
Asphalt MillingsMaterialRecycled asphalt millings are the cheapest way to harden a driveway. Work out tonnage, cubic yards and installed cost here.
Cold Patch & PotholeMaterialMeasure the hole, get the number of 50 lb bags. Works for potholes, trench repairs and edge crumbling.
SealcoatingMaintenanceWork out gallons, 5-gallon pails and cost for sealcoating any asphalt surface.
Parking Lot StripingMaintenanceStall count in, gallons of traffic paint and a cost range out — including ADA spaces and markings.
Deck cost estimatorCostDeck size, material, railing and stairs in — a line-by-line cost estimate out, with the DIY saving shown against the installed price.
Sand calculatorMaterialEnter the area you are covering and how deep the sand goes, pick the sand type, and get the volume in cubic yards, the delivered weight in tons, the bag count and a cost estimate.
Rebar calculatorMaterialEnter the slab dimensions, bar size and grid spacing to get the number of bars each way, total linear feet including laps, tie wire count, steel weight and a cost estimate.
Mulch calculatorLandscapingMeasure the bed, choose the depth, and get the mulch order in cubic yards, bags and dollars — including the point where bulk delivery beats bagged.
Topsoil calculatorLandscapingEnter the area and the depth of soil you are placing, and get the order in cubic yards, tons and bags — plus what a delivered load should cost.
Soil calculatorLandscapingSize the bed, pick the mix, and get the soil volume in cubic feet, cubic yards and bags, split into the topsoil, compost and aeration components of a proper raised bed blend.
Fill dirt calculatorLandscapingEnter the area and the depth of fill, and get loose cubic yards, compacted volume, weight in tons and the number of truckloads to book.
Compost calculatorLandscapingWork out how much compost the job takes, whether you are topdressing a lawn at a quarter inch or amending a bed to a full two inches.
Landscape rock calculatorLandscapingMeasure the bed, pick the rock, and this rock calculator gives you how much landscape rock you need in tons, cubic yards, bags and dollars — plus the tons per square foot, the fabric and the edging that keep it where you put it.
Raised bed soil calculatorLandscapingEnter the garden bed size and fill depth to see exactly how much soil a raised bed needs — in cubic feet, cubic yards and bags, broken into the topsoil, compost and aeration parts of a proper raised bed mix.
Landscaping cost calculatorCostLandscaping is priced by the square foot of what you actually touch, not by the size of the lot. Pick the work, enter the area, and get a cost range with the labour and material split broken out.
Cubic feet per yard of mulchLandscapingOne cubic yard of mulch is 27 cubic feet — 13.5 of the standard 2 cubic foot bags. Convert in either direction below, and see the depth, coverage and price that come with each answer.
Cubic feet calculatorMeasurementEnter dimensions in whatever units you measured in and get the volume in cubic feet, plus every conversion you are likely to need for ordering material.
Cubic yard calculatorMeasurementThe unit every bulk supplier quotes in. Enter your dimensions in any units and get cubic yards, plus the conversions and truckload count that go with an order.

Frequently asked questions

+How do I work out how much asphalt I need?

Multiply area in square feet by compacted depth in feet, multiply by 145 lb per cubic foot, then divide by 2,000 for US tons. One ton covers about 80 square feet at 2 inches compacted.

+How thick should an asphalt driveway be?

2 inches of compacted surface course over 6-8 inches of aggregate base for cars, and a 2-inch binder plus 1.5-inch surface course over 8 inches of base where trucks or RVs park.

+What does a new asphalt driveway cost per square foot?

Roughly $7-$13 per square foot installed in 2026, with resurfacing at $3-$6 and full replacement at $8-$15. Labour, haul distance from the plant and excavation drive most of the variation.

+When is the best time of year to pave?

Late spring to early autumn in cold climates, when air temperature stays above 50°F and asphalt plants are running. Hot mix must be compacted before it drops below about 185°F.
