Shell vs finished
The finish tier changes the price more than the size does. A finished interior can cost three times a bare shell of the same footprint, so match the tier to the quote you are comparing.
Quote prep
Builders, kits, and the big line items
DIY route
Pole barn kits
A material kit ships the posts, trusses, metal, and fasteners for a DIY shell. Confirm what the kit includes versus what you buy separately.
Floor
Concrete slab
A concrete floor is a big line item and often separate from the shell. Estimate the slab volume and cost with the concrete slab calculator.
Openings
Overhead and entry doors
Overhead doors, a walk door, and windows are priced per opening. Plan them separately from the per-square-foot shell.
Formula shown
How the pole barn estimate works
1. Footprint area
area = width x length
2. Pick a per-square-foot band
shell $15-35, turnkey $25-55, finished $50-110
3. Installed total and range
total = area x price; range = area x (band low to band high)
What moves the price
Roof pitch, ceiling height, number and size of overhead doors, insulation, site grading, concrete thickness, wind and snow loads, and permits all shift the per-square-foot cost. Get itemized quotes for anything beyond the basic shell.

FAQ
Pole barn cost questions
Answers for pole barn cost per square foot, shell vs finished, 30x40 pricing, and the concrete slab.
How much does a pole barn cost? + -
Installed pole barn cost depends on size and finish. In 2026 a bare shell runs about $15 to $35 per square foot, a turnkey building with a concrete slab, doors, and basic electrical about $25 to $55, and a fully finished interior $50 to $110 or more. A 30 by 40 ft turnkey building is roughly $48,000 at the midpoint.
What is included in a pole barn shell versus a finished building? + -
A shell is the posts, trusses, roof, and metal siding. Turnkey adds a concrete floor, overhead and walk doors, and basic electrical. Finished adds insulation, interior walls, and full electrical or plumbing. Each tier roughly doubles the per-square-foot cost of the one before it.
How much does a 30x40 pole barn cost? + -
A 30 by 40 ft pole barn is 1,200 square feet. As a contractor-installed shell it is often $18,000 to $42,000, and as a turnkey building with slab, doors, and electrical about $30,000 to $66,000 in 2026. Set the per-square-foot price to your own quotes for a closer number.
Does the price include the concrete slab? + -
Only in the turnkey and finished tiers. A bare shell usually does not include a floor. A concrete slab is a large separate line item — estimate it with the concrete slab calculator and add it if your shell quote excludes it.
Is this pole barn estimate a quote? + -
No. It is a planning estimate. Post-frame pricing varies widely by region, size, roof pitch, door count, site prep, and permits. Use it to sanity-check builder quotes, then confirm the scope in writing.
