These two build the same thing, a place to sit out back, in completely different ways. A patio is a slab poured on the ground. A deck is a wood structure framed above it. Price is not close, and often the ground decides for you before the customer’s budget ever comes up.
The price gap is real
Take a 300 square foot sitting area. At the example rates:
| Surface | Example rate | 300 sq ft total |
|---|---|---|
| Concrete patio, broom | $9 / sq ft | $2,700 |
| Concrete patio, stamped | $16 / sq ft | $4,800 |
| Deck, pressure-treated | $40 / sq ft | $12,000 |
| Deck, cedar | $50 / sq ft | $15,000 |
| Deck, composite | $60 / sq ft | $18,000 |
Example rates only, your market sets the real number. Even a stamped patio comes in at a fraction of the cheapest deck, because the deck price carries framing, posts, railing, and the decking boards on top. A patio is concrete and a finish.
When the grade forces a deck
Cost is not always the deciding factor, the ground is. A patio needs near-level grade to sit right, and it needs to drain away from the house. On a sloped yard or off a raised back door, pouring a patio means hauling in fill and building retaining, which erases its price advantage fast. A deck just stands on posts and spans the drop. Flat yard, lean toward the patio. Sloped or elevated, the deck is often the honest answer even though it costs more.
Upkeep runs opposite ways
Concrete asks for almost nothing, maybe a seal now and then, and its failure mode is a crack that is cosmetic and permanent. Wood decks ask for regular cleaning and a stain or seal on a cycle, plus a board swapped here and there over the years. Composite cuts most of that maintenance but you pay for it up front. Neither is wrong, they are different deals: low upkeep and a possible crack, or ongoing care and a surface you can refresh.
Which to quote
Quote the patio when the yard is flat, budget leads, and the customer wants a low-upkeep surface. Quote the deck when the grade demands it or they want the warm look and feel of wood off the back door. Price your own on the concrete patio calculator and the deck calculator, and the build methods are in how to price a concrete patio and how to price a deck build.
