Free estimating tools
Get material quantities right the first time
MaterialsCalc is a free set of construction material calculators. Enter your dimensions and get the tons, cubic yards or bags of asphalt, gravel or concrete to order, backed by density charts and cost guides.
It is built for contractors, estimators and homeowners planning a driveway, slab, patio or landscaping job who need an order quantity they can check. Every calculator page explains its formula, uses the same density values as the reference charts (for example, 145 lb/ft³ for compacted hot mix asphalt and 2,400 kg/m³ for reinforced concrete), and adds a waste allowance before rounding to what a supplier sells.
