Construction & Trades Calculators

Build with better numbers

Construction estimation errors cost the industry billions annually in overruns and waste. The most common source? Manual takeoff mistakes and unit conversion errors.

Construction tools

• Material takeoffs: Concrete slabs/footings, lumber framing, drywall counts.
• Roofing and cladding: Pitch-area conversion, shingle counts with waste factor.
• Excavation: Cut/fill volumes, trench calculations.
• Cost estimation: Per sq ft pricing, labour bundling, markup and margin.
• Compliance checks: Stair rise/run, railing heights (reference only).

Planning tools, not engineering documents. Follow local building codes and consult licensed professionals.
