## What is Construction Calculator?

Construction calculator answers, not math homework — that's Plumb: type your dimensions in feet-inches-fractions (8' 6 3/8") or metric, and get the exact amount to order — with waste factored in and every formula backed by published construction references.

Every calculator is free. Forever. No account to create, nothing to unlock to get your numbers, and never a subscription.

CONCRETE CALCULATOR — slabs, footings, columns and sonotubes. Cubic yards to order, 80/60/40 lb bag counts (real Quikrete yields), and estimated cost. From a patio slab to a full pour.

TILE CALCULATOR — floor or wall area, tile size, grout joint, and waste factor in. Tiles and boxes to buy out, with coverage per box so you can sanity-check at the store.

STAIR CALCULATOR — total rise in, code-checked risers out (IRC 7-3/4" max), tread count, total run, stringer length and stringer count. Stairs without the guesswork.

FRAMING CALCULATOR — stud counts at 16" or 24" on center with corners and openings, plate stock in linear feet, and board feet for 2x4 or 2x6 walls.

DECK CALCULATOR — deck boards by stock length, board rows, joist counts at 12" or 16" centers, and deck screws by the industry rule.

CONCRETE BLOCK CALCULATOR — CMU counts by wall size, courses, mortar bags, and optional vertical rebar layout.

REBAR ESTIMATOR — grid layout for slabs: bars each way, total linear feet, weight by bar size (#3, #4, #5), and 20 ft sticks to buy.

DRYWALL SHEETS & MUD — sheet counts for 4x8 or 4x12, plus screws, joint tape, and compound from standard estimating rules.

PAINT COVERAGE — gallons by room size and coats, with standard door and window deductions, at real-world coverage.

FLOORING & PLANK ESTIMATOR — boxes of plank, laminate, or vinyl by coverage, with waste for straight or diagonal lays.

ROOFING CALCULATOR — squares from footprint and pitch, shingle bundles, underlayment rolls, and ridge cap.

GRAVEL & AGGREGATE TONNAGE — cubic yards and tons of aggregate, crushed stone, or sand by area and depth.

ASPHALT TONNAGE — hot-mix tonnage at standard 145 lb/ft³ density for driveways and patches.

MORTAR BAGS — coverage for block or brick from manufacturer coverage data.

BOARD FEET & LUMBER VOLUME — volume and cost from nominal dimensions, piece by piece.

BALUSTER SPACING — code-safe spindle counts and even gaps under the 4" sphere rule.

TIME CARD CALCULATOR — weekly hours with breaks, overtime past 40, and pay totals. Round to the quarter hour like payroll does.

PLUMB PRO — one purchase, yours forever: PDF cut-list export for the crew, project folders that group every calc for a job, saved history with cross-device sync, and share-to-crew. The calculators never go behind the paywall.

Built for contractors, carpenters, masons, remodelers — and every homeowner pouring a first patio. From patio slabs to full pours: if it needs ordering, Plumb tells you how much.
