Material only — no labor, permits, delivery, railings, or stairs. Verify joist and beam sizes against your local span tables before ordering; span capacity depends on species and grade.
The flagship tool: enter your deck size and height and get a full material takeoff — decking, joists, beams, posts, footings, concrete bags, screws, joist hangers, and ledger hardware — with an estimated material cost.
Decking boards, field joists, rim joists, a built-up beam, posts, post bases, concrete for footings, joist hangers, structural screws or bolts, ledger flashing and bolts (for attached decks), deck screws or hidden clips, and joist tape. The calculator above lists quantities for all of them.
Roughly 29 boards of 16 ft decking, 13 joists of 2×10 at 12 ft, about 60 linear feet of rim joist, a 2-ply 16 ft beam, three 4×4 or 6×6 posts, three footings with 12-18 bags of concrete, 500 deck screws, and 26 joist hangers — about $2,400-$3,600 in 2026 material pricing for pressure-treated.
For framing, budget one joist for every 16 inches of deck length, plus rim joists on all open sides, plus a two-ply beam along each support line. The tool above computes exact piece counts and linear footage.
10% is right for a rectangular deck with straight cuts. Go to 15% when you're picture-framing, mitering corners, or running boards diagonally.
No. Use the deck railing calculator for railing material and the deck stair calculator for stringers and treads, then add both to the material cost above.
