What goes into pressure-treated deck cost

A pressure-treated wood deck typically costs $15 to $35 per square foot installed, covering framing, decking boards, railings, and labor. Enter your deck size in square feet and the calculator returns a planning range with a midpoint.

Ground-level decks land at the low end; raised decks with stairs, permits, and railings climb toward the top. Pressure-treated lumber is the budget choice up front, though it needs staining every few years to hold up.

Ranges reflect materials plus typical professional installation across the U.S. Your actual price depends on site conditions, access, gates or stairs, permits, and local labor rates. Always collect a couple of local bids before you set a budget.

Frequently asked questions

How much does a pressure-treated deck cost per square foot?
Installed pressure-treated decks run about $15 to $35 per square foot. A 200 square foot deck therefore lands somewhere around $3,000 to $7,000 depending on height, stairs, and railing.
Is a pressure-treated deck cheaper than composite?
Yes, up front. Pressure-treated lumber costs noticeably less to install than composite, but it needs regular cleaning and staining. Composite costs more initially and saves on maintenance over its life.
