How this calculator works
A pergola’s price tracks two choices: the material and whether you buy a kit or build custom. This tool turns both into a footprint-based estimate.
Material and build type
The per-square-foot ranges cover posts, beams, rafters, and anchoring for a freestanding structure. Pressure-treated is the budget wood baseline and cedar the step up, but both need periodic sealing. Vinyl and basic aluminum are priced close to pressure-treated and shrug off weather with no staining — the premium end of the aluminum range is where the modern, heavier-framed structures sit. Fiberglass tops the range and spans the farthest without extra posts.
The build type toggle matters as much as the material: a prefab kit arrives pre-cut and is the easy path for DIY, so it earns a discount here; a custom build adds design and labor cost but lets you size and style it freely.
DIY reality check
Switch to DIY for materials-only pricing. A kit on a flat, finished surface is a genuine weekend job. The moment you need concrete footings, are attaching to the house, or your town requires a permit for a permanent structure, the difficulty — and the case for hiring out — goes up. Check local rules before you dig.

Frequently asked questions
How much does a pergola cost in 2026?
A typical 12×12 pergola runs roughly $4,000–$8,000 installed, depending on material and whether it's a kit or custom-built. Small cedar or pressure-treated kits can come in under that; large custom aluminum or fiberglass structures go well above.
What's the cheapest pergola material?
Vinyl and pressure-treated wood are the lowest upfront cost, with basic aluminum close behind — and unlike the wood, vinyl and aluminum skip the staining and won't rot. Cedar costs more than all three. Fiberglass is the priciest and the strongest, allowing longer spans without sagging. The right pick depends on how much maintenance you'll tolerate.
Is a kit cheaper than a custom pergola?
Usually yes. A prefab kit ships pre-cut with hardware, so it's faster to install and easier to DIY — this tool applies a discount for kits and a premium for custom site-built work. Custom buys you exact sizing, heavier timbers, and design freedom a kit can't match.
Can I build a pergola myself?
A kit on a level patio is a realistic weekend project for two people with basic tools; switch the toggle to DIY to see materials-only cost. Custom builds, attached pergolas, and anything requiring footings or permits raise the difficulty — and many areas require a permit for a permanent structure.
Does a pergola add shade or home value?
An open-rafter pergola gives partial, dappled shade; add a canopy, louvered roof, or climbing plants for more. It's primarily a lifestyle and curb-appeal upgrade rather than a strong dollar-for-dollar resale investment — the payoff is the outdoor room it creates.
