Concrete, Gravel, Mulch & Material Calculators
Free construction and landscaping material calculators: cubic yards, tons and bags for concrete, gravel, mulch, sand, topsoil, pavers, brick, asphalt.
Every calculator here starts from your real dimensions -- length, width, depth -- and converts the result straight into what you'd actually order: cubic yards, tons, or bags. No generic "how much do I need" guessing, and no account required.
Volume-based materials (concrete, gravel, mulch, sand, topsoil, asphalt) use the same length × width × depth math contractors use for estimating. Pavers and brick use real per-unit coverage rates instead, since those are counted in pieces, not poured or spread.
Material Calculators
Calculate how many cubic yards of concrete -- or how many 60lb/80lb bags -- you need for a slab, footing, or pour.
Concrete Slab CalculatorCalculate cubic yards, bags, ready-mix trucks, cost, mesh or rebar, and the gravel base for a concrete slab from your real dimensions.
Gravel CalculatorCalculate cubic yards, tons, bags, and cost of gravel for a driveway, path, or drainage base, by gravel type.
Mulch CalculatorCalculate cubic yards, bags, coverage, and cost of mulch for a garden bed, based on your real area and depth.
Sand CalculatorCalculate cubic yards and tons of sand for a paver base, play area, or fill project.
Topsoil CalculatorCalculate cubic yards, tons, or bags of topsoil for a lawn, garden bed, or grading project.
Asphalt CalculatorCalculate tons of hot mix asphalt needed for a driveway or parking area, from your real dimensions.
Paver CalculatorCalculate how many pavers you need for a patio or walkway, plus the gravel base and sand setting bed underneath.
Brick CalculatorCalculate how many bricks -- and how much mortar -- you need for a wall or veneer project, from real wall dimensions.
Tile CalculatorCalculate how many tiles and boxes you need for a floor, wall, or shower, from area, tile size, grout joint width, and waste.
Grout CalculatorCalculate how many pounds -- or bags -- of grout you need for a tile job, from tile size, joint width and depth, and area.
Shingle CalculatorCalculate roofing squares and shingle bundles needed for a roof, from your real roof surface area.
Footing CalculatorCalculate cubic yards and bags of concrete for continuous strip footings or round pier footings, from real dimensions.
Drywall Mud CalculatorCalculate gallons, pounds, and buckets of joint compound for a drywall job, plus joint tape and screws, from the square footage.
Rebar CalculatorCalculate linear feet and weight of rebar needed for a slab, from your real dimensions, grid spacing, and bar size.
Frequently Asked Questions
Are these calculators accurate?
They use standard, published trade formulas and rule-of-thumb material densities, not original research or lab measurements -- the same figures contractors use for planning. Real material weight and coverage vary by exact product and moisture content, so treat the numbers as solid planning estimates, and buy a little extra as standard trade advice.
Why cubic yards instead of cubic feet?
Bulk materials (concrete, gravel, mulch, sand, topsoil, asphalt) are almost always sold and delivered by the cubic yard, so that's the number that actually matters when you're ordering -- this site shows cubic feet too, but cubic yards is the headline figure.
