Scenario 1
150 ft wood privacy fence, 6 ft tall, one walk gate
Length: 150 ft
Posts (8 ft spacing): ceil(150/8) + 1 = 20
Material rate: $30/ft installed
150 ft x $30/ft = $4,500 material and labor
20 posts x 2 bags x $5.50 = $220 footings
1 walk gate at $275 = $275
Estimated total: $4,995
This falls inside the $4,200 to $7,500 national range reported for 150 ft wood privacy installs in 2026.
Scenario 2
200 ft chain link, 4 ft tall, no gates, DIY labor
Length: 200 ft
Posts (10 ft spacing): ceil(200/10) + 1 = 21
Material rate: $12/ft material-only
200 ft x $12/ft = $2,400 material
21 posts x 1.5 bags x $5.50 = $173.25 footings
Labor: $0 (DIY)
Estimated total: $2,573.25
Removing labor from a chain link job often cuts total cost by 40% to 50% compared to contractor installation.
Scenario 3
120 ft vinyl fence, 6 ft tall, one drive gate, sloped yard
Length: 120 ft
Posts (8 ft spacing): ceil(120/8) + 1 = 16
Terrain: Sloped, 15% labor increase applied
120 ft x $42/ft = $5,040 base install
Sloped terrain labor adjustment: +$189
1 drive gate at $650 = $650
Estimated total: $5,879
Sloped and rocky terrain rarely change material cost but reliably increase labor hours per foot.
