Aggregate Calculator
Estimate aggregate needed in tons, cubic yards, or bags for base layers and fills.
Construction Calculators
Use these calculators to estimate quantities, coverage, and materials for common construction projects.
CalcShed's construction calculators estimate materials for concrete, roofing, framing, and masonry work before you order. Each tool uses standard industry formulas with an adjustable waste allowance, so you buy the right quantity the first time - with outputs in cubic yards, bags, board feet, squares, or piece counts depending on the job.
Asphalt Calculator
Calculate asphalt quantity by area and thickness. Outputs tons and cubic yards with waste.
Brick Calculator
Estimate bricks per square foot plus mortar bags for any wall, with waste.
Cement Calculator
Estimate cement required by volume or bags with common mix assumptions.
Concrete Bag Calculator
Convert slab/footing volume into 60 lb and 80 lb bag counts with waste.
Concrete Footing Calculator
Estimate concrete volume for strip or pad footings based on dimensions.
Concrete Slab Calculator
Estimate slab concrete volume in cubic yards and bag equivalents.
Fence Calculator
Estimate fence posts, rails, and pickets by total fence length and height with waste included.
Framing Calculator
Calculate studs, top plates, and bottom plates for wall framing by length and ceiling height.
Gravel Calculator
Estimate gravel quantity for driveways and base layers in tons and cubic yards.
Lumber Calculator
Calculate board feet and lumber cost by thickness, width, and length for any framing or woodworking project.
Metal Roofing Calculator

Frequently Asked Questions
What construction calculators does CalcShed offer?
Tools for concrete (slabs, footings, bags, ready-mix), roofing (pitch, squares, trusses), framing (studs, lumber, board feet), and masonry (brick, retaining wall), plus aggregates, pavers, and asphalt.
How accurate are the material estimates?
They use standard industry formulas and coverage rates and include an adjustable waste factor. Treat the results as close planning estimates and confirm with your supplier and local code requirements.
How much waste should I add?
A 5–10% allowance is typical for most materials; add more for complex cuts, angles, or patterned layouts. Every calculator lets you set the waste percentage.
Do these calculators check building-code compliance?
No. They estimate quantities only. Verify code-driven requirements - such as rebar spacing, footing depth, or fastener schedules - with your local building authority.
