What moves the number
Size and boards
Area scales linearly; composite boards roughly double material vs pressure-treated, exotics more. Rail length matters.
Height premium
Elevated decks (×1.25) need deeper footings, beams, stairs, and full rail — ground-level platforms skip most of that.
Footings and frost
Frost-depth footings and soils vary by state; helical piles vs dug footings change the base-work line.
Permits
Most jurisdictions permit attached and elevated decks. State-indexed allowance included; cities set the real fee.

Is this quote a contractor bid?
No — a planning estimate. Soil, frost depth, and ledger conditions vary; get 3 local bids.
