  "description": "A 40x60 pole barn is the workhorse size for equipment storage, a large shop, or a small riding arena — 2,400 square feet of clear span with no interior columns if you truss it properly. This calculator lays out the post count on your chosen spacing, sizes the truss count, computes wall and roof panel area from the sidewall height and roof pitch, and returns a materials-plus-labor budget. 2026 US national averages for a finished shell run roughly $25-$45 per square foot depending on sidewall height, concrete, doors, and whether you insulate. Everything here is editable so you can drop in a supplier's actual panel and post pricing.",
  "formula": "Posts = Perimeter ÷ Spacing + corners. Roof Area = Length × Width × Pitch Factor. Cost = Shell Rate × Floor Area + Concrete + Doors.",
