Deck Cost Calculator
A deck cost calculator estimates your total price by multiplying the deck square footage by a price per square foot that you set. Because decking materials range widely (pressure-treated wood to composite), you enter your local price, and the calculator returns an estimated material cost. Enter your deck size and price below.
Enter the deck size to see the estimate.
Materials and labor vary widely by region and over time. Use a local quote to confirm.
How Do You Estimate Deck Cost?
To estimate deck cost, calculate the deck square footage, then multiply by your price per square foot. Decking material drives the range: pressure-treated wood is cheapest, cedar and hardwood cost more, and composite is the most expensive. The calculator lets you enter your own per-square-foot price for accuracy, and remember that the substructure (joists, beams, posts, footings) and labor are separate, often larger, costs.
What Affects the Cost of a Deck?
Deck cost is driven by the decking material, the framing lumber, the height and complexity (stairs, railings, multiple levels), and labor. Composite decking costs more upfront but less to maintain. Footings, posts and railings add up, and labor often equals or exceeds materials. Treat the calculator as a decking-surface estimate and budget separately for the frame, railings and labor.

Frequently asked questions
- How much does a deck cost?
- Deck cost depends on material and size, from pressure-treated wood to composite, so enter your local price per square foot. Framing, railings and labor are separate.
- Is composite decking more expensive?
- Yes, composite costs more upfront than pressure-treated wood but needs less maintenance. Enter your chosen material's price in the calculator.
