Formula and methodology
Formula: floor area=L×W; wall area=2(L+W)H; roof area=L×W/cos(pitch); cost=sum(area×rate)×(1+waste).
This is a surface-area budget model for a simple rectangular shed. It excludes foundations, openings, framing, fasteners, labor, permits, utilities, delivery, tax, and local material prices unless represented by your rates.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Shed length (m) — minimum 0.1; maximum 1000
- Shed width (m) — minimum 0.1; maximum 1000
- Wall height (m) — minimum 0.1; maximum 100
- Roof pitch angle (°) — minimum 0; maximum 80
- Floor material rate per m² — minimum 0; maximum 100000
- Wall material rate per m² — minimum 0; maximum 100000
- Roof material rate per m² — minimum 0; maximum 100000
- Waste allowance (%) — minimum 0; maximum 100
Worked example
| Input | Value |
|---|---|
| Shed length (m) | 4 |
| Shed width (m) | 3 |
| Wall height (m) | 2.2 |
| Roof pitch angle (°) | 20 |
| Floor material rate per m² | 35 |
| Wall material rate per m² | 28 |
| Roof material rate per m² | 22 |
| Waste allowance (%) | 10 |
Estimated material-only cost≈1,161.09 currency units.
Assumptions and limits
- Length, width, and height are in metres and rates are per square metre in the user's currency.
- The roof is modeled as two equal planes over the full footprint.
- Rates and waste are planning inputs, not a quote or structural design.
