Deck Cost Calculator — What Will My Deck Cost?
Deck cost scales with size, material and whether you DIY or hire out. Enter your deck dimensions and species for a realistic build-cost range — and a full code-compliant framing plan so your estimate is grounded in real lumber.
Member sizes read from the IRC R507.6 (joists) and R507.5 (beams) tables for No. 2 Southern Pineat 40 psf live + 10 psf dead. Footings from tributary load ÷ soil bearing (R507.3); ledger fasteners per R507.9. Confirm with your local building department.

Low = DIY material budget; high = contractor-installed (labor included). Regional prices vary — treat as a planning range, not a quote.
Deck Cost — what to know
- •Pressure-treated pine is the cheapest framing; cedar and redwood cost more but resist rot and look better as decking.
- •Labor is roughly half a contractor-built deck's cost — doing your own framing is where the savings are.
- •Footings, stairs, railings and permits add up fast; this estimate covers the structure, not built-ins or grading.
