Deck Calculators
A deck is two estimates stacked: the frame underneath, priced as lumber, and the surface on top, priced as decking. Composite changes the second one without touching the first.
There are 5 calculators here: 10x12 Deck Material List Calculator (the full material list for a 10 by 12 foot deck), 12x16 Deck Cost Calculator (material list and cost for a 12 by 16 foot deck), 16x20 Deck Material List & Cost (full material list and cost for a 16 by 20 foot deck), Deck Board & Joist Calculator (board count, joist count and framing for a deck), and 1 more below.
They all work the same way: quantity first, then a waste allowance you can change, then a price built from verified figures and adjusted for your state. Cost is always a range rather than a single number, and every assumption behind it is printed on the page with its source and the date it was last checked.
Topics in Deck Calculators
- Deck Cost CalculatorsCost per square foot for a deck is a range, not a number, because the framing under a 12x16 barely changes while the decking on top can triple in price.2 calculators
- Deck Material List CalculatorsCut lists rather than prices: joists at their spacing, boards at their width, and the fasteners that follow from both.3 calculators
