The bigger the square footage, the more you can expect to pay. The type of deck boards you use will also factor into your overall cost. Where you're putting your deck also matters. If it's low enough to the ground, you may be able to place the joists on four-way deck blocks rather than digging post holes.

How Much Does a Composite Deck Cost? Composite decks generally cost about $30 to $45 per square foot installed. For a 16x20-foot deck, that works out to $9,600 to $14,400. Budget on the high end of that price range if you’re adding features like railings or benches to the deck.
The initial cost of composite decking materials is competitive with hardwoods. However, the long-term costs are much lower. Composite decking has a very long life span with very little maintenance needed. The cost of composite decking won’t break the bank, particularly when you consider the long-term savings.
