Decking Calculators
Deck questions come in two kinds: quantity questions this site answers (how much stain, how many boards) and structural questions it deliberately refuses (spans, footings, loads), because those answers live in code tables keyed to your species, spacing, and jurisdiction, and a web calculator guessing at them is how decks end up in the news. What's here is the honest quantity math, sourced.
Not Sure Where to Start?
Deck Builder Cost Calculator is the one most people need. Most deck searches are really a budget question. This one builds the cost band from materials and modeled labor, and links the quantity tools as you go.
Maintain and Finish
Stain by real first-coat coverage bands. Weathered wood drinks more; the tool says so.
What a Deck Costs
Four different angles on the same budget question: materials-first, planning, hiring a builder, and the labor line alone.
- Deck Builder Cost CalculatorSee what's actually inside a deck builder's bid (burdened wage, overhead, and profit) and why two honest bids for the same deck can differ sharply.
- Deck Building Price CalculatorDeck price bands move on size, material class, and site conditions, not a single average. See the NAHB-anchored cost structure behind the number honestly.
- Deck Construction Cost CalculatorCount deck boards, joist spacing, and screws first, then see a modeled labor band next to a sampled stud price. Built for DIYers pricing their own build.
- Deck Labor Cost CalculatorLabor-only deck cost: a published carpenter wage run through burden and markup, scaled by crew-hours; see what actually moves the number, not materials.
What the Prices Are Doing
At the producer level, softwood lumber costs 15% more than a year ago, prepared paint 6.2% more (BLS Producer Price Index, July 2025 to July 2026, unadjusted 12-month change). Decking rides the lumber market, and lumber is up double digits on the year. Price the boards last, closest to the build date. Full picture on the Cost Index.
