Cost To Build A Deck

If you’re building a new deck, it’s likely that your most pressing question is “how much does it cost to build a deck?” While there are no easy answers to the question, there are still a few variables you can solve. Although the costs for labor and installation can vary from contractor to contractor, you can get a rough estimate for the amount of materials you’ll need to build your new deck.

How much does it cost to build a deck?

Costs for materials for a deck range according to a number of factors, including:

  • Square footage of your deck plan
  • Height, width, and depth of your planned structure
  • How elaborate your design is (for example, is there enough room in the budget for a shed roof?)
  • The type of materials you plan to use and how much they cost within your particular region of the country

For instance, let’s look at average costs for a 10’ x 10’ deck:

  • If using pressure-treated pine, you may pay between $1,061 to $2,350 for materials
  • Materials for that same 10’ x 10’ deck can cost between $3,003 and $6,297 if using exotic hardwood
  • Using composite to build a 10’ x 10’ deck can cost between $1,983 and $4,293

If you were to go a bit bigger and build a 20’ x 18’ deck:

  • If that deck had a height of 8’2” and ran a total of 339 square feet, pressure-treated pine would be your least-expensive option for materials at $3,062. If you used exotic hardwood, materials would cost nearly $8,000. If you opted for composite, cost of materials would be $5,318.
  • Now, if you built a deck with a height of only 3’9”, costs would be less expensive with economical pressure treated pine running $2,775. Exotic hardwood materials would cost $7,245 and composite may cost $4,603.

Please keep in mind that these costs can vary according to a number of the factors we’ve talked about before. However, you can use the calculator below to get the best possible estimate for materials for your new deck.
