Calcstead Shows Its Work
A suite of home-project calculators for estimating materials, purchase quantities, and adjustable costs.
Field notes
Calcstead organizes 46 calculators into project groups including concrete, aggregates, garden and lawn, walls and floors, roofing, decks, and brick or block work. Its stated workflow takes dimensions, unit preferences, waste allowances, and locally entered prices, then converts the result into buying formats such as 80-pound bags, paint cans, tile boxes, pallets, or roofing bundles. The homepage example reports 3.5 cubic yards of concrete as 147 nominal bags and warns that results are planning aids rather than contractor quotes.
