LiveExample Data
Sample scenarios to validate inputs and expected outputs.
| Scenario | Length | Type | Gates | Panels/Pickets | Posts | Concrete bags | Materials ($) | Total ($) |
|---|---|---|---|---|---|---|---|---|
| Backyard privacy | 120 ft | Panels | 1 | 15 panels | 18 | 24 | 2,350.00 | 4,100.00 |
| Side yard pickets | 80 ft | Pickets | 0 | 176 pickets | 11 | 14 | 1,120.00 | 2,050.00 |
| Corner lot mix | 200 ft | Panels | 2 | 23 panels | 30 | 40 | 3,980.00 | 7,240.00 |
Formula used
- Usable length = total length − (gate count × gate width).
- Panels = ceil(usable length ÷ panel width).
- Posts (panel) = panels + 1 + corner/end posts + (gates × 2).
- Rails (panel) = panels × rails per panel.
- Posts (picket) = floor(usable length ÷ post spacing) + 1 + corner/end posts + (gates × 2).
- Pickets = ceil((usable length × 12) ÷ (picket width + gap)).
- Rails (picket) = (posts − 1) × rails per bay.
- Concrete volume/post = π × (hole diameter/24)2 × hole depth. (All dimensions in feet.)
- Concrete bags = ceil((posts × volume/post) ÷ bag yield).
- Materials cost = Σ(item count × unit cost) × (1 + misc%/100) × region factor.
- Labor hours = (usable length ÷ productivity) + (gate count × extra gate hours).
- Labor cost = (labor hours × crew rate + mobilization) × region factor.
- Tax = materials cost × (tax%/100). (Tax on materials only.)
- Total = materials cost + labor cost + tax.
- Cost/ft = total ÷ total length.
Common panel sizes and coverage
Quick reference for popular sections. Posts assume straight runs without extra corners.
| Panel height | Panel width | Coverage per panel | Panels per 100 ft | Posts per 100 ft |
|---|---|---|---|---|
| 6 ft | 8 ft | 8 ft | 13 | 14 |
| 8 ft | 8 ft | 8 ft | 13 | 14 |
| 4 ft | 8 ft | 8 ft | 13 | 14 |
| 6 ft (alt) | 6 ft | 6 ft | 17 | 18 |
Concrete bags per post lookup
Calculated from cylindrical holes. Yields: 50 lb=0.375 ft³, 60 lb=0.45 ft³, 80 lb=0.60 ft³.
| Hole Ø (in) | Depth (in) | Volume (ft³) | 50 lb bags | 60 lb bags | 80 lb bags |

Fence type cost benchmarks
Indicative ranges only. Pricing varies by region, season, and specification.
| Fence type | Materials ($/ft) | Installed ($/ft) | Notes |
|---|---|---|---|
| Wood panels (privacy) | $12–$25 | $25–$55 | Includes posts, rails, panels; stain/paint extra. |
| Wood pickets (site-built) | $10–$22 | $28–$60 | More labor; flexible spacing and styles. |
| Vinyl panels | $24–$40 | $45–$85 | Low maintenance; higher material cost. |
| Chain-link (4 ft) | $8–$15 | $15–$30 | Posts set in concrete; fabric and fittings included. |
