All paving calculators

How much asphalt, base and patch material the job takes.

• Asphalt TonnageEnter 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.
• Gravel BaseThe base course carries the load — get it wrong and the asphalt above it fails. Size your crushed aggregate here.
• Asphalt MillingsRecycled asphalt millings are the cheapest way to harden a driveway. Work out tonnage, cubic yards and installed cost here.
• Cold Patch & PotholeMeasure the hole, get the number of 50 lb bags. Works for potholes, trench repairs and edge crumbling.
• Sand calculatorEnter 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 calculatorEnter 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.

Stone, gravel and aggregate quantities, weights and conversions.

What contractors charge, broken down line by line.

• Driveway CostGet an installed price range for a new asphalt driveway, broken down into base prep, paving and extras.
• Resurfacing CostAn overlay is roughly half the cost of a full replacement — if the existing base is still sound. Price it here.
• Replacement CostFull tear-out and repave, priced line by line: demolition, disposal, base and new pavement.
• Deck cost estimatorDeck size, material, railing and stairs in — a line-by-line cost estimate out, with the DIY saving shown against the installed price.
• Landscaping cost calculatorLandscaping 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.

Pavers, retaining walls and the base under them.

• Paver calculatorEnter your patio or driveway size, pick a paver and a laying pattern, and get the paver count with pattern cut waste plus the full base build: gravel, bedding sand and joint sand.
• Retaining wall calculatorEnter the wall length, exposed height and block size to get the course count, total blocks including buried courses, capstones, leveling pad gravel and drainage stone.
• Deck calculatorOne deck, one set of numbers. Enter the size and the material and this deck building calculator returns the board count, the framing, the footings, the fasteners and what the whole thing costs.
• Deck board calculatorThe decking-only number: how many boards, how many linear feet, and what the layout you have chosen adds in offcuts.
• Deck framing calculatorThe part of the deck nobody sees and every inspector checks. Joist count, joist size against the span, beam posts, hangers and blocking.
• Deck footing calculatorFootings are the only part of a deck you cannot fix later. Work out how many, how deep for your frost line, and how much concrete to buy.

Mulch, topsoil, compost and fill by the yard, bag or truckload.

• Mulch calculatorMeasure 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 calculatorEnter 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 calculatorSize 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 calculatorEnter 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 calculatorWork 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 calculatorMeasure 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 calculatorEnter 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.
• Cubic feet per yard of mulchOne 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.

Area, depth, compaction and unit conversions.

• Square FootageAdd up rectangles, circles and triangles to get the total paving area in every unit contractors quote in.
• Thickness & CompactionTwo questions, one tool: how deep will my tonnage go, and how much loose mix do I need to hit a compacted depth?
• Tons ↔ Cubic YardsSuppliers quote tons, plans specify yards. Convert between them for any asphalt or aggregate density.
• Cubic feet calculatorEnter 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 calculatorThe 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.

Sealcoating, striping and keeping pavement alive.

• SealcoatingWork out gallons, 5-gallon pails and cost for sealcoating any asphalt surface.
• Parking Lot StripingStall count in, gallons of traffic paint and a cost range out — including ADA spaces and markings.
