Shed Cost Calculator

Methodology

Cost = area × (build-type $/sq ft + foundation $/sq ft), low and high ends. Build-type ranges ($18–55 prefab, $40–100 site-built wood, $70–180 custom, $100–250 workshop) are from EstimationPro AI shed cost data, 2026 (as of 2026-10-14). Foundation ranges (gravel $2–4, blocks $3–5, slab $7–12 per sq ft) are from HomeRenoCalc, Cost to Build a Shed in 2026 (as of 2026-10-14). The build-type ranges already assume a gravel pad, so the gravel add-on makes the estimate slightly conservative. Excludes permits and electrical.
