BuilderCalc: Deck, Framing

Deck spans, joist sizing, header & beam loads, rafter cuts, concrete yardage — instant answers + a shopping list. Built by builders. Works offline. Free to start.

The construction calculator a contractor actually uses on the job site — tile, drywall, concrete, paint, framing — every material estimate, with waste built in.

Tap a project. Answer 2–3 questions. BuilderCalc tells you exactly how much to buy — humanized ("Buy 3 gallons, about $90–$140"), the shopping list to bring, and the mistakes that cost real money every year.

FIVE GUIDED PROJECT FLOWS

• Paint a room — wall area minus openings, primer + coats, gallon estimate • Tile a bathroom — square footage, box count, waste factor, grout volume • Build a deck (Pro) — joist spacing, beams, posts, footings, decking, fasteners • Install drywall (Pro) — sheets by room, screws, mud, tape • Pour a concrete slab (Pro) — slab, footers, columns, bags or yards

EVERY FLOW INCLUDES

• The humanized result, not just decimals • The shopping list to bring to the hardware store • The mistakes to dodge — sourced from JLC, Fine Homebuilding, This Old House, and the IRC
