How Much Will Your New Deck Cost?
Here is a calculator to get you in the ballpark.
Enter the width and length of the deck; then choose the decking type, the fasteners, and the railing style to see what the materials will cost. Cost estimates are based on national averages obtained through phone calls to lumber centers across the U.S.
Framing: Calculate the cost of the floor frame excluding posts and beams.
Decking: Choose among six types of decking and three types of fastening systems.
Railing: Choose a simple or fancy wood railing, or pick a modular synthetic-railing system.
