A new deck is a big investment, and the first question everyone asks is simple: how much will it cost? The honest answer is that it depends, mostly on the material you choose, the size of the deck, and how complex the design is. The good news is that those factors are predictable, so once you understand them, you can build a realistic budget before you ever call a builder.
This guide breaks deck pricing down by material, by size, and by style, using current 2026 numbers. It also covers the cheapest materials, what goes on a deck materials list, and the smartest ways to save without ending up with a deck you regret. By the end, you will know roughly what your project should cost and where your money goes.
The Short Answer: Average Deck Cost
Most decks cost between $25 and $60 per square foot installed in 2026, including materials and labor. A typical 300 square foot deck lands somewhere around $10,000 to $20,000 in mid-range materials. A small, simple wood deck can come in under $5,000, while a large composite or hardwood deck with premium railings can climb past $40,000.

Those ranges are wide because no two decks are the same. The three biggest levers are material, size, and style. Let us look at each one.
Deck Cost by Material
Material is the single biggest factor in your deck budget. The chart below shows typical installed costs per square foot for the main options, from the cheapest deck material up to premium PVC.
| Material | Installed per sq ft | Notes |
|---|---|---|
| Pressure-treated wood | $15 to $40 | The cheapest decking material. Needs sealing every few years. |
| Cedar | $30 to $50 | Natural rot resistance and a warm look. Still needs upkeep. |
| Composite | $35 to $70 | Low maintenance. Mid-grade to premium capped boards. |
| PVC | $55 to $80+ | Fully synthetic, top moisture resistance, longest warranties. |

If your only goal is the lowest price, pressure-treated wood is the cheapest deck material by a clear margin. Just remember the long game. Wood needs staining or sealing every few years, while composite and PVC skip that yearly cost and last longer, which can close the price gap over a couple of decades.
Where Your Deck Budget Goes
It helps to know what you are actually paying for. People often quote only the board price, then get surprised by the total. In reality, labor is usually the biggest slice of the pie.
On most professional builds, labor runs a little more than half the total, materials make up roughly a third, and permits plus site prep round out the rest. This is why doing it yourself saves so much. You cut the labor, which is the biggest line, while still paying for the same materials. It is also why a complex design costs more, since tricky framing and angled cuts add labor hours.
Deck Cost by Size
Bigger decks cost more, but not always in a straight line, because some fixed costs like the permit and mobilization do not change much. Here are realistic 2026 ballparks for common sizes in mid-range materials.
| Deck size | Typical installed cost | Good for |
|---|---|---|
| 120 sq ft (small) | $3,000 to $7,000 | A simple platform, grill, and a couple of chairs. |
| 200 sq ft (medium) | $8,000 to $14,000 | A dining set plus a small seating area. |
| 300 sq ft (large) | $10,000 to $20,000 | Separate dining and lounge zones. |
| 500 sq ft (extra large) | $20,000 to $45,000 | Multi-zone outdoor living, premium materials. |

Deck Cost by Style
The design drives cost as much as the size. A plain rectangle is the most affordable. Every level, angle, and feature you add takes more material and labor.
- Ground-level platform. The cheapest style. No tall posts or long stairs, and often no railing where code allows.
- Raised deck. Adds footings, taller posts, stairs, and required railing, which all raise the price.
- Multi-level deck. Two or more connected platforms cost more in framing and labor, often 20 to 30 percent above a simple deck of the same size.
- Curved or wraparound. Angled cuts and extra framing make these the most labor-intensive, and the most expensive per square foot.
Features add up too. Railing runs roughly $35 to $120 per linear foot depending on material, a staircase often adds $500 to $2,000, and extras like built-in seating, lighting, or a pergola each add to the total. None are wasteful, but knowing the cost lets you choose what matters.
What Goes On a Deck Materials List
If you are pricing a build yourself, a clear deck materials list keeps you from missing something at the store. A complete materials list for a deck usually includes:
- Footings and framing. Concrete, post bases, pressure-treated posts, beams, and joists.
- Connections. Joist hangers, structural screws, bolts, and the ledger board with flashing.
- Decking. The boards you walk on, plus hidden fasteners or deck screws.
- Railing and stairs. Posts, rails, balusters, stair stringers, and treads.
- Finishing. Fascia board to wrap the frame, and stain or sealer if you build with wood.
Many free deck design tools generate a materials list for you, which is a great starting point for a budget. Just treat it as an estimate, then price it locally. Our look at deck materials at Menards can help, and knowing where to buy deck materials lets you compare prices before you buy.
How to Save Money on Your Deck
You can trim a deck budget without ending up with a deck you dislike. The trick is to cut in the right places.
- Choose a simple shape. A clean rectangle is far cheaper than curves or multiple levels, and it still looks great.
- Start with pressure-treated. If budget is tight, the cheapest decking material gets you a solid deck now. You can upgrade the surface later.
- Keep it low. A ground-level platform skips the cost of tall posts, long stairs, and required railing.
- Phase the extras. Build the deck now, then add the pergola, lighting, or fire feature in a later season.
- Do the prep yourself. Clearing the site or handling demolition can shave labor off the bill.
- Right-size it. A smaller deck you fully use beats a large one you paid extra to build and barely touch.
Is a Deck Worth the Money?
For most homes, yes. A deck is one of the better returns in home improvement. A wood deck recoups roughly 80 percent of its cost at resale, and composite returns a bit less up front but saves years of maintenance. Beyond the resale math, a deck adds living space you actually use, which is value that does not show up on a spreadsheet.
Frequently Asked Questions
What is the cheapest way to build a deck?
A small, ground-level platform in pressure-treated wood with a simple rectangular shape is the cheapest deck to build. Skipping railing where code allows and doing the labor yourself saves the most.
What is the cheapest decking material?
Pressure-treated wood is the cheapest decking material, at roughly $15 to $40 per square foot installed. It needs sealing every few years, which adds a small ongoing cost.
How much does a 300 square foot deck cost?
A 300 square foot deck typically costs about $10,000 to $20,000 installed in mid-range materials. Premium composite, PVC, or a raised design pushes it toward the high end.
Is composite or wood cheaper?
Wood is cheaper up front. Over 20 years the gap narrows, because composite skips yearly staining and lasts longer. If you plan to stay in the home, composite often pays off.
How can I get an accurate deck price?
Start with these ranges to set a budget, then get a written quote from a local builder. A builder factors in your exact size, material, height, and site, which a general estimate cannot.
The Bottom Line
A deck costs what it costs for clear reasons: material, size, and style. Pressure-treated wood is the cheapest material, a simple rectangle is the cheapest style, and labor is the biggest single line in the budget. Use the ranges in this guide to plan, decide where to spend and where to save, and you will avoid the sticker shock that catches people off guard.
When you are ready for a real number, the best step is a written quote from a local builder.
