Free construction calculators and material estimators
Explore 26 free online construction calculators for concrete, cement, gravel, brick, tile, paint, lumber, square footage, material quantities, schedules, and preliminary project costs. Enter measured dimensions and select appropriate units to prepare a working estimate.
Construction quantities are planning estimates, not engineered designs or supplier quotes. Verify field measurements, drawing dimensions, waste allowances, material specifications, structural requirements, local building codes, labor, taxes, and delivery costs before ordering or building.
