1 A composite deck can cost $25-$70 or more a square foot, or $8,000-$22,400 for 16'x20', depending on the brand, project complexity and whether construction is done by casual labor or a licensed contractor.
Let's Crunch Some Numbers. Planning your dream deck can be a lot of work. But with the Trex Deck Cost Calculator, we've made it easier to estimate the cost of materials for a Trex deck. By factoring in the anticipated size of your project along with the estimated costs for material, you'll have a better idea of just how much it will cost to build a high-performance composite deck. To give you a general idea, the average material costs for a deck run about $12.12 per square foot.
