What This Calculator Does
The Shed Cost Calculator estimates the cost of buying and installing a backyard shed based on size, material, and 2026 pricing. Enter the shed dimensions to get cost ranges for prefabricated sheds, custom-built sheds, and DIY kits. This broad estimate helps you plan your backyard storage budget.
Sheds provide valuable storage space for tools, equipment, and yard supplies. Prefabricated sheds are the most common and affordable option. Custom-built sheds offer maximum flexibility but at higher cost. DIY kits fall between the two. Verify local pricing with shed dealers in your area for a more accurate planning estimate.
How to Use
- Measure the available space in your yard for the shed footprint.
- Select the shed type - prefab, custom-built, or DIY kit.
- Enter length and width in feet.
- Select the material - wood, metal, or resin/plastic.
- Click "Calculate" to see the estimated cost range.
Worked Examples
Prefab Wood Shed for a Suburban Backyard
A 10 x 12 ft prefabricated wood shed with a concrete slab foundation on a level suburban lot, including basic shelving and ramp.
- →Shed unit: 10x12 ft prefab wood shed. Mid-range cost: approximately $4,000 delivered and assembled.
- →Concrete slab foundation: 10x12 ft = 120 sq ft at 4 in thick. Ready-mix concrete: 1.48 cu yd at $150/yard = $222. With labor and forms: $500-$800.
- →Site preparation: grading and gravel base = $200-$400. Permit fee: $50-$200.
- →Assembly labor (if not included): $300-$600. Shelving and ramp: $200-$400.
- →Total mid-range estimate: $4,000 + $650 + $300 + $450 + $300 = $5,700.
Result: A 10x12 ft prefab wood shed with concrete slab and basic features totals approximately $5,000-$6,500 as a planning estimate.
Order the shed in late winter or early spring — demand is lowest and many dealers offer 10-20% off-season discounts. Schedule delivery for a dry week to avoid the base settling into wet ground.
