## What is BuilderCalc?

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

PLUS 14 PRO CALCULATORS UNDERNEATH

Tile · Drywall · Concrete · Paint · Flooring (LVP, hardwood, laminate, carpet) · Framing (studs, plates, headers) · Roofing (squares, underlayment, ridge cap) · Layout (diagonal squareness, stair stringer, rake/run/rise) · Materials waste · Square footage · Conversions · Volume · Coverage · Cost-per-unit

WHO IT'S FOR

Contractors, remodelers, handymen, framers, finish carpenters. Homeowners running a real project. Anyone who'd rather take an extra coffee break than re-measure for the third time.
