Deck Cost Calculator
Estimate deck boards, framing, footings, and fasteners, plus a material and installed cost range by decking material, with optional railing and stairs.
Enter the deck size and height, pick the material, and add railing or stairs if you need them. Composite costs more than pressure treated up front but needs far less upkeep, so weigh the installed range against years of staining and sealing.
| Material-only cost | |
| Deck boards | |
| Joists | |
| Posts / footings | |
| Fasteners | |
| Railing length |
Estimate only. Installed cost includes labor; material-only is for a DIY build. Excludes permits and ledger or foundation work.
