Quick Answer
High-tensile electric fence costs $150–$400 per acre in materials for DIY installation, or $500–$1,200 per acre professionally installed. Smaller properties cost more per acre because the perimeter-to-area ratio is higher — a 5-acre square has proportionally more fencing per acre than a 100-acre square. Interior cross-fencing adds 30–60% to total cost depending on paddock layout.
Cost by Property Size
| Property Size | Perimeter (square) | Material Cost | Installed Cost (DIY) |
|---|---|---|---|
| 5 acres | ~1,870 ft | $550–$1,100 | $900–$1,800 |
| 10 acres | ~2,640 ft | $780–$1,580 | $1,200–$2,500 |
| 40 acres | ~5,280 ft | $1,560–$3,160 | $2,400–$5,000 |
| 100 acres | ~8,340 ft | $2,500–$5,000 | $3,800–$7,500 |
| 200 acres | ~11,780 ft | $3,500–$7,000 | $5,300–$11,000 |
What Drives Per-Acre Cost
Number of wire strands: A 2-strand cattle fence costs half what a 5-strand sheep/goat fence costs per foot. More strands = more wire, more insulators, and more installation time.
Post spacing: Wider spacing (60–80 feet) dramatically reduces post count and cost vs. barbed wire's typical 15–20-foot spacing.
Terrain: Rocky, steep, or heavily vegetated land requires more posts, specialized equipment, and labor — adding 30–80% to installation cost.
Corner complexity: A simple rectangular property has 4 corners. An irregular property with 10–15 corners adds significant cost in brace assemblies.
Interior Cross-Fencing Cost
Dividing a 40-acre property into 4 paddocks of 10 acres requires approximately 2,000 feet of interior fence. At $0.30–$0.60 per foot in materials, that's $600–$1,200 additional — a 30–40% increase over the perimeter-only cost. Plan cross-fencing from the beginning to optimize gate placement and minimize total fence footage.
Our Recommendation
Calculate your property perimeter accurately before estimating cost — most online calculators and field estimates are off by 10–20%. Walk the fence line with a measuring wheel for the most accurate estimate. Add 15% to all wire estimates for gates, connections, and waste. For most operations, a 3–5 strand high-tensile fence is the right choice — cheaper than woven wire, more effective than barbed wire, and lasting significantly longer than both.
