Shed Cost Calculator
Estimate shed cost from size, style, quality, foundation type, and DIY vs pro labor, including a permit allowance on larger floors.
How the calculation works
Shed prices split into kit, foundation, and labor. Big-box kits look cheap until you add a level pad, shingles, and a door upgrade. Many towns exempt small sheds from permits below 100–200 sq ft — this tool adds a permit allowance from 120 sq ft up.
Gable is the default. Barn/gambrel buys loft storage. Modern studios cost more per foot. A concrete slab is the most durable floor; gravel with skids is the usual DIY path and can be moved later.
Formula
Worked example
A 12×10 standard gable on a gravel pad, DIY, is a mid-range backyard budget; a premium barn with a slab and a crew costs several times more.

Frequently asked questions
How much does a 10×12 shed cost?
A basic kit can be $1,500–$3,500. Delivered and installed with a pad often lands $4,000–$9,000.
Do I need a permit?
Often above 100–200 sq ft, or if it has electricity. Rules are local.
Slab or gravel?
Gravel and skids for a typical backyard kit. A slab for a workshop, heavy mower, or HOA that wants permanent.
Kit vs custom?
Kits are faster. Custom matches the house roof pitch and siding at a higher price, which the premium tier approximates.
Can I DIY?
Yes if you can square a floor and shingle a small roof. Two people and a weekend is a realistic 8×10–10×12 kit.
