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?

Yes. Enter the material rate that matches your selected product.
