Free deck cost calculator: estimate the cost to build a deck from size, decking material (pressure-treated, composite, cedar, PVC), railing, and region.
Planning notice: This deck cost calculator models installed decking and railing bands from footprint and material class—not structural engineering, permit fees, or demolition of an old deck. Local code, frost depth, and ledger attachment details can move real bids beyond any web table.
Summary: Enter deck length and width (ft), decking material, whether to add railing, and a regional index. You get low–mid–high USD bands for the cost to build a deck, deck area in sq ft, implied mid $/sq ft, and a material comparison table for your size.
