It depends on the length of the fence, the height of the fence, and the terrain where it is installed. Generally, barbed wire fences cost anywhere from $5 to $10 per linear foot.

It can cost anywhere from $0.50 to $5 per foot, depending on the material used and the height of the fence. For example, a simple ranch-style fence with posts spaced every 6 feet can cost as little as $3 per foot to install, while a more elaborate security fence with tighter post spacing and a special top rail can cost up to $10 per foot. Barbed wire fences are usually installed in one of two ways: by stapling it to wooden posts or by driving metal T-posts into the ground and then attaching the wire to those posts. The installation method will affect the overall cost of the project.
