What this calculator does
The DIY shed cost calculator gives a rough materials-based estimate for building your own storage shed, based on floor area, material grade, and extras.
The formula
Total cost is estimated as floor area (length times width) multiplied by a per-square-foot material rate that depends on the grade of materials you choose, plus any extra costs like windows, a ramp, or shelving. These per-square-foot rates are rough industry averages for material-only DIY builds and do not include a builder’s labor.
This tool is for general planning purposes only. Actual costs vary significantly by region, current lumber prices, foundation type, and permit fees, so use this as a starting point rather than a final quote.
