How this calculator works
Estimated total = deck area × (material rate + labor rate) + railing + permit/miscellaneous allowances.
Worked example
A 20 × 16 ft deck at $18 material and $22 labor per sq ft, plus $3,000 in other costs, totals about $15,800.
Sources & assumptions
Every price is entered by the visitor. CalcCaddy does not treat these inputs as market quotes; confirm materials, labor, railing, permitting, foundation, and site-work costs locally.
Frequently asked questions
Why is this a range tool rather than a quote?
Deck costs vary heavily by framing, height, stairs, railing, footings, demolition, access, and local labor.
Can I use composite decking?
