How Much Does a Pergola Cost? 2026 Price Guide + Calculator

The average pergola costs $3,000 to $7,500 installed in 2026 for a standard 10x10 footprint, or roughly $30 to $75 per square foot. A budget cedar kit you build yourself runs as low as $1,200, while a custom aluminum or motorized louvered pergola can clear $20,000. This guide gives you real 2026 prices by size, material, and install type, the one-line formula contractors use to ballpark a quote, and the 7 cost factors that decide where your project lands in the range.

Average pergola cost in 2026 (quick answer)

• National average installed — $4,500
• Typical price range (10x10 to 12x14) — $3,000 to $9,000
• Per square foot installed — $30 to $75

Pergola cost by size

Most residential pergolas fall between 80 and 200 square feet. Price scales almost linearly with footprint because posts, beams, and rafters all grow with the span.

• 8x8 (64 sq ft) — $1,900 to $4,800 installed
• 10x10 (100 sq ft) — $3,000 to $7,500 installed
• 10x12 (120 sq ft) — $3,600 to $9,000 installed
• 12x12 (144 sq ft) — $4,300 to $10,800 installed
• 12x14 (168 sq ft) — $5,000 to $12,600 installed
• 12x16 (192 sq ft) — $5,800 to $14,400 installed
• 16x16 (256 sq ft) — $7,700 to $19,200 installed
• 20x20 (400 sq ft) — $12,000 to $30,000 installed

Pergola cost by material

• Pressure-treated pine — $15 to $35 per sq ft (cheapest, 7–10 yr lifespan)
• Cedar — $25 to $50 per sq ft (rot-resistant, classic look, 15–20 yr)
• Redwood — $35 to $60 per sq ft (premium, deep red tone)
• Vinyl — $30 to $55 per sq ft (zero maintenance, white only)
• Fiberglass — $45 to $75 per sq ft (long spans, paintable)
• Aluminum — $50 to $100 per sq ft (modern, rust-proof, 25+ yr)
• Steel — $40 to $80 per sq ft (heavy frame, industrial look)

The 60-second pergola cost formula

Total cost = Length ft × Width ft × Material rate × Install factor

Use 1.0 for DIY kit, 1.4 for pro install of a kit, and 1.8 to 2.2 for fully custom build. Add $1,500 to $4,000 for a concrete pad if you don't already have one, and 8 to 12% for permit and disposal in most municipalities.

Worked example — 12x14 cedar pergola, pro install

1. Footprint: 12 × 14 = 168 sq ft
2. Material rate (cedar mid-range): $38/sq ft
3. Install factor (pro custom): 1.8
4. Subtotal: 168 × 38 × 1.8 = $11,491 — round to $11,500
5. Add concrete footings (4 posts at $250): +$1,000
6. Permit and disposal (10%): +$1,150
7. Final estimate: roughly $13,650

Kit vs custom vs prefab — what's the difference?

• Pergola kit — pre-cut lumber or aluminum delivered flat. $1,200 to $6,000 materials. 1 weekend with 2 people. Best value for standard sizes.
• Prefab / pre-assembled — shows up mostly built on a truck. $4,000 to $12,000. Crane or 4-person lift required.
• Custom built on site — contractor designs and frames to your space. $6,000 to $20,000+. Best for odd dimensions, attached pergolas, and roof-tied builds.
• Motorized louvered (smart pergola) — adjustable aluminum slats, often with rain sensors and LED lighting. $10,000 to $25,000+.

DIY vs hiring a pro

A 10x10 cedar kit takes a confident DIYer about 12 to 16 hours over a weekend and saves $2,000 to $4,000 in labor. The catch: you need to dig four footings below frost line, set posts perfectly plumb, and lift 12-foot beams overhead. Hire a pro if your site slopes more than 6 inches across the footprint, if the pergola attaches to the house, or if your municipality requires a stamped engineering drawing (common above 200 sq ft).

7 factors that move your pergola price

1. Size — every extra square foot adds $30 to $75 installed.
2. Material — aluminum and fiberglass cost 2 to 3x cedar.
3. Roof style — open-rafter is cheapest; louvered, polycarbonate, and shade-cloth roofs add $500 to $4,000.
4. Attached vs freestanding — attached to the house saves 2 posts but needs a ledger board and flashing (often a wash).
5. Foundation — existing concrete pad is free; new footings run $200 to $400 per post.
6. Permits — most cities require one above 100 to 200 sq ft. Budget $100 to $500.
7. Add-ons — lighting ($300 to $1,500), fans ($200 to $800), curtains ($150 to $600), and built-in heaters ($400 to $2,000).

Does a pergola add value to your home?

Remodeling Magazine's 2025 Cost vs Value report puts outdoor structures at a 50 to 80% resale recoup, and Zillow listings with the word "pergola" sell for an average 4.0% premium. The bigger win is usability — a pergola turns 100 to 200 sq ft of underused yard into shaded living space, which appraisers increasingly count toward outdoor square footage in warm climates.

How to save money on a pergola without cheaping out

• Pick a standard size (8x8, 10x10, 12x12) — kits are mass-produced and 20 to 30% cheaper.
• Choose pressure-treated pine and stain it cedar-tone — saves $1,000+ on a 10x12.
• Build over an existing patio or deck — skip the $1,500 concrete pad.
• Order in fall or winter — contractors discount 10 to 20% in the off season.
• Skip the louvered roof on year one — frame for it now, add it later when budget allows.
• Get 3 quotes — pergola pricing varies wildly by contractor; the spread is often 40%.

FAQ

How much does a 10x10 pergola cost?

A 10x10 pergola costs $3,000 to $7,500 installed in 2026. A DIY cedar kit runs $1,500 to $3,500 in materials; an aluminum louvered version of the same size starts around $8,000.

How much does a 12x12 pergola cost?

Expect $4,300 to $10,800 installed for a 12x12, depending on material. Cedar mid-range runs about $6,500 installed; aluminum closer to $9,000.

Is it cheaper to build or buy a pergola?

Buying a pre-cut kit is cheaper than buying raw lumber and cutting yourself for any standard size — manufacturers get better lumber pricing and the joinery is pre-routed. Custom-build only wins on non-standard footprints or when you already have surplus material.

Do I need a permit for a pergola?

Most municipalities require a permit for any freestanding structure over 100 to 200 sq ft, or for any pergola attached to the house. Permit fees run $100 to $500. Always check with your local building department before digging footings — fines for unpermitted work can hit $1,000+ and force a tear-down.

How long does a pergola last?

Pressure-treated pine lasts 7 to 10 years, cedar and redwood 15 to 20 years with maintenance, vinyl 20 to 25 years, and aluminum or fiberglass 25+ years. Annual cleaning and a fresh coat of stain every 2 to 3 years can double a wood pergola's lifespan.

How much does a motorized louvered pergola cost?

Motorized louvered (smart) pergolas run $10,000 to $25,000+ installed. A 12x12 model from a name-brand US manufacturer averages $15,000 with LED lighting and a rain sensor.
