Fencing quotes swing wildly because two jobs of the same length can be completely different work. Here is what goes into the per-foot number so you can read a bid and budget honestly.
The short version
Materials are the smaller half of most fence budgets. Corners, braces, terrain, clearing and labor drive the rest. Price a fence by the run, the corners and the ground — not just by the roll of wire.
The pieces of a per-foot price
Wire or panel: barbed wire is the cheapest per foot, high-tensile sits in the middle, woven or field fence costs more, and welded panels or board fence cost the most by a wide margin.
Posts: line post spacing (usually 10-16 ft for wire) sets how many you buy. T-posts are cheap; treated wood line posts cost several times more and last longer in rough country.
Corners and braces: an H-brace or corner assembly costs many times a line post, and every corner, gate and change of direction needs one. A field with lots of angles costs more per foot than a straight run.
Gates and hardware: each gate is a fixed cost that gets averaged into the per-foot figure on a short fence and disappears on a long one.
Labor: often half or more of a contracted job. Hand-digging in rock costs far more than driving posts in bottom ground.
Why identical lengths get different quotes
Terrain. Rock, slopes, creek crossings and timber all slow the crew down and add braces.
Clearing. Brush, old fence removal and fallen trees are usually billed separately or rolled into a higher per-foot rate.
Access. If the crew cannot get a tractor and post driver along the line, the job becomes hand work.
Livestock class. Fence that has to hold goats, sheep or a bull is a different build than a fence for calm cows.
Matching fence to the animal
Cattle: 4-5 strand barbed or high-tensile electric works for most herds. Bulls and weaned calves need more strands or tighter spacing.
Horses: avoid barbed wire. Woven wire with a top board or rail, or coated high-tensile, keeps legs out of trouble.
Goats and sheep: woven wire with small openings, or several hot wires. Goats find every weak spot in a fence, so this is where cheap fencing costs the most.
Poultry and rabbits in tractors or runs: welded wire with a small mesh, plus a buried apron or skirt against diggers.
Where the money is actually saved
Straighten your lines. Fewer corners means fewer brace assemblies, which is often the single biggest saving on a small field.
Do the clearing yourself before the crew shows up, if you have the equipment and the time.
Buy materials as a full job, not a roll at a time — and check farm auctions and marketplace listings for unused posts, wire and gates from finished projects.
Build permanent perimeter fence once and split paddocks with movable electric. Interior fence does not need to be a monument.
Budgeting your project
Measure the perimeter honestly, then count corners, gates and stream crossings separately. Those three lines explain most of the variance between bids.
Get at least two bids and ask each one to itemize materials, braces, gates and labor. A per-foot number with nothing behind it cannot be compared.
Ask what happens if the crew hits rock, and get the answer in writing before work starts.
Budget for a gate at every place you will realistically want one. Adding it later costs more than including it now.
