A new pergola in 2026 costs somewhere between $3,500 and $15,000 for most backyard builds, with the national average landing around $25 to $60 per square foot installed. A 10 × 10 pergola runs $2,500 to $6,000, a 12 × 12 hits $3,600 to $8,600, and a larger 10 × 20 structure can reach $5,000 to $12,000. The spread is wide because material choice moves the needle more than almost anything else — pressure-treated pine is half the cost of vinyl or composite, and a DIY kit undercuts a contractor-built custom by thousands.
Size matters, but not in a straight line. Doubling the footprint doesn't quite double the cost because you're adding posts and rafters, not footings and beams at the same rate. And the shade you get isn't just a function of size — rafter spacing and orientation control how much sun actually filters through, which is the whole point of a pergola in the first place. We'll walk through all of that, plus the concrete work most people forget to budget for.
2026 pergola cost by material
Material is the single biggest cost driver. Pressure-treated lumber is the budget workhorse — cheap, strong, and you'll be staining or sealing it every few years. Cedar looks better out of the gate and weathers to gray if you let it, but costs nearly double. Vinyl and composite skip the maintenance but bring a much higher sticker price, and some people find them too uniform-looking for a backyard structure. Metal pergolas — usually powder-coated aluminum or steel — fall somewhere in the middle on cost and virtually never need attention after install.
| Material | Cost per sq ft | 10×10 (100 sq ft) | 12×12 (144 sq ft) | Lifespan / upkeep |
|---|---|---|---|---|
| Pressure-treated pine | $25–$40 | $2,500–$4,000 | $3,600–$5,800 | 15–20 yrs / seal every 2–3 yrs |
| Cedar / redwood | $35–$50 | $3,500–$5,000 | $5,000–$7,200 | 20–25 yrs / seal optional |
| Composite | $45–$65 | $4,500–$6,500 | $6,500–$9,400 | 25+ yrs / wash only |
| Vinyl (PVC) | $50–$70 | $5,000–$7,000 | $7,200–$10,100 | 25+ yrs / wash only |
| Aluminum / steel | $40–$60 | $4,000–$6,000 | $5,800–$8,600 | 30+ yrs / none |
Those figures assume a contractor build with standard post spacing and a straightforward attached or freestanding design. If you're assembling a kit yourself, knock off roughly 40–50% for labor. Custom metalwork or engineered timber-frame joinery can push costs well past the high end of these ranges.
Cost by size: the square-foot trap
Per-square-foot pricing is a useful shorthand, but it hides the fact that small pergolas cost more per foot than large ones. A 10 × 10 might run $35/sq ft while a 10 × 20 drops closer to $28/sq ft, because both need four posts, four footings, and two main beams — you're just stretching the rafters and adding a few more of them on the bigger one. Fixed costs like permits, site prep, and the first hour of labor get spread thinner as size grows.
| Size | Area (sq ft) | Total cost | Effective $/sq ft |
|---|---|---|---|
| 10 × 10 | 100 | $2,800–$4,200 | $28–$42 |
| 12 × 12 | 144 | $3,800–$5,800 | $26–$40 |
| 10 × 16 | 160 | $4,200–$6,200 | $26–$39 |
| 10 × 20 | 200 | $5,000–$7,600 | $25–$38 |
| 12 × 20 | 240 | $6,000–$9,200 | $25–$38 |
The other size consideration is span. Rafters and beams can only stretch so far before they sag or need to be upsized to heavier, pricier lumber. A 10-foot rafter span is trivial with a 2×6; a 16-foot span might demand a 2×8 or 2×10, and that drives up material cost per linear foot. The pergola calculator accounts for this and suggests appropriate beam and rafter dimensions based on your footprint.
Attached versus freestanding
An attached pergola bolts to your house with a ledger board, sharing one side of the structure with the existing building. A freestanding pergola stands on its own four (or more) corners. Attached pergolas save you two posts and two footings, so the material cost drops a bit — maybe 10–15% on a typical build. But attached means flashing the ledger properly so water doesn't wick behind your siding, and it often means working around existing eaves, doors, or windows. Freestanding is simpler structurally and can go anywhere in the yard, but you're paying for all four corners.
For budgeting: figure an attached 10 × 12 pressure-treated at roughly $3,200–$4,800, versus $3,600–$5,400 freestanding. The gap narrows as size grows because the shared wall is a smaller percentage of the total.
The footing concrete nobody budgets for
Every post needs a footing, and every footing needs concrete. Most codes want footings below the frost line — 12 inches deep in the South, 42 inches or more across the northern tier — and wide enough to spread the load. A typical 10-inch-diameter footing, 36 inches deep, swallows about 1.4 cubic feet of concrete, or roughly one and a half 60-pound bags. Four posts means six bags; six posts means nine. At $6–$8 per bag in 2026, that's $50–$70 in concrete alone, plus the post bases or brackets.
If you're pouring your own footings, the concrete calculator will tell you exactly how many bags or cubic yards you need for a given hole size and count. It's not a huge expense, but it's one more line item that turns a $3,000 lumber package into a $3,800 installed project once you add fasteners, hardware, sealer, and the concrete.
Shade coverage: the beam and rafter math
- Rafters running east–west block the most midday sun; north–south gives morning and evening shade but lets noon sun through.
- Rafter spacing controls coverage. 12 inches on-center is roughly 50% shade; 16 inches is closer to 40%; 24 inches is light dappling.
- Adding a second layer of cross-beams (a double-rafter grid) can push shade coverage past 60%, but costs more in material and labor.
- The pergola shade calculator estimates coverage percentage based on rafter size, spacing, and orientation.
DIY versus hiring a contractor
Labor typically runs 40–50% of a contractor-installed pergola, so doing it yourself can cut the bill nearly in half. A 12 × 12 pressure-treated pergola that costs $5,000 installed might be $2,800 in materials if you build it — lumber, hardware, concrete, fasteners, and stain. The catch is that you're digging four or six post holes, mixing and pouring concrete, cutting notches for beam connections, squaring the frame, and making sure the whole thing is plumb and level. It's a full weekend for someone handy, or two weekends if you're learning as you go.
| Approach | Materials | Labor / tools | Total | Your time |
|---|---|---|---|---|
| DIY from scratch | $2,400–$3,200 | ~$200 (tool rental) | $2,600–$3,400 | 2–3 weekends |
| DIY kit (unassembled) | $3,200–$4,500 | ~$0 | $3,200–$4,500 | 1–2 weekends |
| Contractor-built | $2,400–$3,200 | $2,200–$3,400 | $4,600–$6,600 | A few days |
Kits split the difference. They arrive pre-cut with all the hardware, so you're not sizing beams or making compound cuts — you're assembling pieces. The premium over raw lumber is typically 20–30%, but you save hours of measuring and cutting, and the risk of a structural mistake drops way down. If you've built a deck before, a pergola kit is well within reach. If this is your first outdoor structure, hiring it out buys you a frame that's square, level, and properly anchored.
A worked example: 10 × 16 cedar pergola, DIY
You're planning a freestanding 10 × 16 pergola (160 sq ft) in cedar, doing the build yourself.
- Four 6×6 cedar posts, 10 ft long: $320
- Two 2×8 beams, 16 ft: $180
- Ten 2×6 rafters, 10 ft: $240
- Post bases, joist hangers, lag bolts, carriage bolts: $150
- Concrete for four footings (10″ dia., 36″ deep): twelve 60-lb bags: $85
- Cedar stain/sealer, 2 gallons: $90
- Post-hole digger rental: $60
Total: ~$1,125 materials + $60 rental = $1,185, or about $7.40 per square foot. A contractor would charge closer to $6,400–$8,000 installed ($40–$50/sq ft), so you're saving roughly $5,200 in labor at the cost of two or three weekends and some sore shoulders.
Run your own dimensions through the pergola calculator to get beam sizes, rafter counts, and a material list, then cross-check the footing concrete with the concrete calculator before you start digging.
Kit versus scratch-build
Pergola kits have gotten a lot better over the past five years. You're not buying cheap pine with wobbly brackets anymore — most mid-tier kits now use treated or cedar lumber with galvanized hardware, pre-cut to length with all the fasteners bagged and labeled. The main trade-off is customization. A kit gives you fixed dimensions and a set design; building from scratch means you can size the pergola to exactly fit your deck or patio, adjust rafter spacing for the shade coverage you want, and pick your own lumber grade.
Cost-wise, expect to pay 20–35% more for a kit than raw lumber. A 10 × 12 pressure-treated kit might run $1,800–$2,400, where the same footprint in raw 4×4s and 2×6s would be closer to $1,400–$1,800. The premium buys you speed and certainty — everything fits, nothing needs re-cutting, and you're not second-guessing beam spans halfway through the build. For a first-time project, that peace of mind is usually worth the extra few hundred.
What drives the cost up
Beyond material and size, a handful of factors can push a pergola estimate higher:
- Curved or angled designs. Any shape that isn't a rectangle means custom cuts, more waste, and slower assembly. Budget an extra 15–30%.
- Integrated lighting or ceiling fans. Running electrical to the pergola adds wiring, a permit, and often a dedicated circuit. Plan for $800–$2,000 depending on distance from the panel.
- Retractable canopy or shade fabric. A fixed canopy kit adds $400–$1,200; a motorized retractable system can hit $2,000+.
- Site access and terrain. If a truck can't get close or the ground is sloped, labor hours climb. Rocky soil that fights a post-hole digger can double excavation time.
- Permits. Not universal, but many jurisdictions require one for a pergola over a certain size or attached to a dwelling. Fees range from $50 to $300.
Common questions about pergola cost
Does a pergola add value to a home?
A well-built pergola is one of the more visible outdoor upgrades, and it signals that the backyard is finished and usable. Resale impact varies by market — in warm climates where outdoor living is year-round, a pergola can return 50–70% of its cost. In colder regions the return is lower, but it still helps a house show better. The bigger value is in how much more you use the yard once there's defined shade and structure.
How much shade does a pergola actually provide?
A standard pergola with 2×6 rafters spaced 16 inches on-center gives you roughly 35–45% shade coverage, depending on the sun angle and rafter orientation. That's enough to take the edge off midday heat but not enough to replace a solid roof. Tightening rafter spacing to 12 inches pushes coverage closer to 50%, and adding a second layer of cross-slats or a fabric canopy can get you past 70%. The pergola shade calculator estimates coverage based on your specific rafter size, spacing, and direction.
Do I need a permit to build a pergola?
It depends on your jurisdiction and whether the pergola is attached or freestanding. Many areas require a permit for any structure over a certain size (often 120 or 200 square feet) or anything attached to the house. Freestanding pergolas under the size threshold sometimes fly under the radar, but codes vary widely. A quick call to your local building department settles it, and pulling a permit now is a lot easier than dealing with it at resale when a buyer's inspector flags an unpermitted structure.
How long does a pergola last?
Pressure-treated lumber properly maintained can give you 15–20 years; cedar or redwood can push 20–25. Composite, vinyl, and metal pergolas are typically warrantied for 25+ years and often outlast that if the footings stay solid. The weak point is almost never the structure itself — it's usually the footings heaving in freeze-thaw cycles or the ledger attachment failing on an attached pergola because the flashing wasn't done right. Get the foundation and attachment details correct, and the pergola will outlive most decks.
The bottom line
Budget $3,500 to $8,000 for a typical backyard pergola in 2026, with material choice and labor approach driving most of the spread. Pressure-treated is the budget play; cedar splits the difference; composite and vinyl cost more upfront but skip the maintenance. DIY cuts the bill nearly in half if you're comfortable with post holes and a level, and kits make that route a lot more approachable than it used to be. Don't forget the footings — they're boring, invisible, and the single thing that determines whether your pergola is still standing square in twenty years or listing like a shipwreck in five.
