Construction Material Calculators
Estimate concrete, brick, lumber, and other construction materials accurately with our free building calculators.
Accurate material takeoffs are essential for any construction project. Our construction material calculators help you estimate concrete volume, brick counts, lumber quantities, rebar weights, sand and gravel volumes, and more. Reduce waste, control costs, and order the right amount the first time.
Construction Materials Calculators (10)
Concrete Calculator
Calculate how much concrete you need for slabs, footings, columns, or post holes. Get results in cubic yards, cubic feet, and number of bags, plus a cost comparison between bagged and ready-mix concrete.
Brick Calculator
Calculate exactly how many bricks you need for any wall project. Enter your wall dimensions, subtract door and window openings, choose your brick size and mortar joint, and get an accurate brick count with waste factor included.
Lumber Calculator
Calculate board feet, total linear feet, estimated weight, and project cost for any lumber order. Select nominal dimensions, species, and quantity to get an accurate estimate with waste factor included.
Rebar Calculator
Calculate how much rebar you need for concrete slabs, footings, and walls. Enter your dimensions, rebar size, and spacing to get bar count, total linear feet, weight in pounds, number of 20-foot bars to purchase, and a complete cost estimate.
Excavation Calculator
Calculate excavation volume in cubic yards, soil weight by type, number of dump truck loads, and total project cost including labor, equipment, disposal, and permits. Enter your dimensions and rates to get an instant estimate.
Retaining Wall Calculator
Calculate the exact number of blocks, stones, or timbers needed for your retaining wall — plus gravel backfill, concrete footing, labor, and total project cost. Works for concrete block, natural stone, interlocking block, timber, and boulder walls.
Stair Calculator
Calculate the number of risers, tread depth, stringer length, and total material quantities for your staircase. Get an instant cost estimate for stringers, treads, and risers — plus a code-compliance check against IRC requirements.
Crushed Stone Calculator
Calculate exactly how much crushed stone you need for driveways, patios, bases, and drainage. Enter your area dimensions, choose a stone type and coverage shape, and get cubic yards, tons, bag count, and a full cost estimate including delivery.
Post Hole Concrete Calculator
Calculate exactly how many bags of concrete you need for your post holes. Enter hole diameter, depth, post size, and number of posts to get bags needed (40, 60, or 80 lb), cubic yards, and a cost estimate — with post displacement factored in.
Board Foot Calculator
Calculate board feet per board, total board footage for multiple boards, material cost by species, and linear feet equivalent. Enter dimensions and quantity, then click Calculate for an instant estimate with waste factor included.
