Full materials list for wood privacy, picket and chain link fence — posts, rails, pickets, concrete and hardware.
Sod Calculator
Pieces, pallets and cost for any lawn shape. Add rectangles, circles and triangles for irregular yards.
Tile Calculator
Tile count, boxes, thinset and grout for floors and walls. Waste adjusts for your layout pattern, and it picks the right trowel size.
Roof Shingle Calculator
Squares, bundles, underlayment, ridge cap, drip edge and nails. Handles gable, hip and shed roofs with the real pitch multiplier.
Drywall Calculator
Sheets, joint compound, tape, screws and corner bead for any room. Openings come off, waste rounds once, every assumption shown.
Board Foot Calculator
Board feet for a whole cut list, not one board. Nominal sizes, hardwood quarters, waste and cost per board foot.
Conduit Fill Calculator
NEC Chapter 9 fill check for EMT, PVC, IMC and rigid. Add THHN or XHHW conductors, see the fill percent, and get the next size up if you're over.
Work out how much to order — cubic yards, tons, bags and cost. Every one shows its assumptions so you can check the math.
Concrete Calculator
Cubic yards and 80 lb bag counts for slabs, footings and pads — with the bagged-versus-ready-mix crossover made obvious.
Mulch Calculator
Cubic yards, bags and cost for any number of beds. Includes the depth guidance that actually suppresses weeds.
Gravel Calculator
Yards, tons and cost for driveways, paths and drainage — plus how deep each actually needs to be.
Topsoil Calculator
Yards, weight and cost for lawns, raised beds and grading, with settling allowance built in.
Crushed Stone Calculator
Yards and tons for base courses, patios and driveways — including the compaction allowance most people forget.
Sand Calculator
Yards, tons and bags for paver bedding, sandboxes and fill — and which sand to actually use.
Fill Dirt Calculator
Yards, tons and truck loads for grading and levelling, plus why you should not pay topsoil prices for bulk fill.
Asphalt Calculator
Tonnage for driveways, lots and overlays. Hot-mix density built in, since asphalt is sold by the ton.
River Rock Calculator
Yards, tons and cost for beds, borders and dry creek beds, with depth guidance by stone size.
Cubic Yard Calculator
Convert any area and depth to cubic yards, cubic feet and tons. Works for any material.
Compost Calculator
Cubic yards, bags and weight for topdressing, bed prep and new lawns — spread thinner than mulch, and the depth guide says how thin.
