Quick answer
Pole barns typically cost $15–$40 per square foot built: about $15–$20 for basic storage, $20–$35 for a garage or workshop and $40+ for custom buildings. A 30 × 40 garage runs roughly $24,000–$42,000 for the building, plus about $7,000–$14,000 for a concrete slab. Kits cost about half as much if you build them yourself.
What the Pole Barn Cost Calculator does
Enter the footprint and choose the type of building. The calculator prices the structure per square foot, then adds the extras that most kit prices exclude — a concrete slab, insulation and electrical — so you see a realistic total. Labor is often 40–60% of a built price.
The formula
Total = W × L × price per sq ft + slab ($6–$12/sq ft) + insulation ($1.50–$4/sq ft) + electrical. Kits ≈ 55–60% of the built price.
Worked example
40 × 60 enclosed storage, built, no slab: 2,400 × $15–$20 = $36,000–$48,000.
How to use the Pole Barn Cost Calculator
- Enter width and length.
- Choose the building type and kit or built.
