Unit prices are the national baseline scaled by each state's relative construction cost index. Project totals apply a ±12% band to reflect normal quote variation.

How we build these numbers

We start from a US national baseline of $35 per square foot installed and multiply it by each state's relative construction cost index, where 1.00 is the national average. Those indices are directional — they capture broad differences in trade wages, material freight, and permitting overhead, not street-level pricing.

The ±12% band on every figure is deliberate. It reflects the range we would expect between a competitive bid and a premium one for the same scope in the same market. If a quote lands far outside that band in either direction, the scope is probably different from what you think it is — that is worth a conversation before it is worth a signature.

Deck Boards cost by state: FAQ

How much does a deck cost on average in the US?

The national baseline we use is $35 per square foot installed. Applied to a typical typical project of 300 ft², that works out to roughly $9,240–$11,760 in materials at the unit shown. Labor, delivery, tax, and site prep sit on top unless the unit label says "installed."

Which states are most and least expensive for a deck?

The five priciest markets in our index are Hawaii, California, Alaska, New York, District of Columbia — Hawaii runs about $47 per square foot installed. The five cheapest are Mississippi, Arkansas, Oklahoma, Alabama, South Carolina, with Mississippi near $29. Top to bottom that is a spread of roughly 61%, which is why a national average alone is a poor budgeting tool.

Why does the same project cost so much more in some states?

Four things move the number: prevailing wage rates for the trades, freight distance from the nearest supplier or plant, permitting and inspection overhead, and local demand. Labor is usually the biggest lever — in high-wage metros it can be well over half the installed price. Freight matters most for heavy, low-value materials like concrete, gravel, and block, where hauling costs rival the material itself.

Are these numbers quotes?

No. They are directional planning figures built from a national baseline and a relative state cost index, and they are deliberately shown as ranges. Use them to sanity-check a bid or set a budget, not to negotiate a contract. Two contractors in the same ZIP code can legitimately differ by 20–30% based on crew size, backlog, and scope assumptions.

How do I get a number for my specific project?

Run the Deck Board Calculator with your own dimensions and your local unit price. The calculator does the quantity math exactly; this page just tells you what unit price is realistic where you live. Together they give you a defensible budget before you call anyone.
