Formula
Panels = ceiling of (length ÷ panel width). Posts = panels + 1.
Pickets = ceiling of (length in inches ÷ (picket width + gap)). Cost = count × your unit price. The price field means per panel in panel mode and per picket in picket mode.

Fence calculator for panels, posts, and pickets
This fence calculator counts panel-fence posts and panels, or pickets along a straight run. Type your price per panel or picket if you want a fence cost calculator figure for materials only.

How it works
A post at each end, and one between panels.
For panels, the panel count is the fence length divided by the panel width, rounded up. Posts are panels plus one, because a run needs a post at both ends. A 100 foot line of 8 foot panels is not an even 12.5, so the count rounds to 13 panels and 14 posts. For pickets, the count is the length in inches divided by the picket width plus the gap, rounded up. Gates, corners, and slopes add posts or change the run. Price them as extra, not as part of the straight-line count.

Example
100 feet of 8 foot panels.
100 ÷ 8 is 12.5, which rounds up to 13 panels and 14 posts. At a placeholder of $35 per panel, the panels are $455. Posts, concrete, and rails are not in that $455.

Tips
Corners split the run.
Calculate each straight side, then add the posts carefully so the corner post is not counted twice. A gate replaces a panel and needs its own hardware. Sloped ground can require a different post spacing than the catalog panel width.

Equipment
Post holes are an auger job.
Fence contractors use skid steers and augers. If you are buying that equipment for the business, Dengaro takes applications from $15,000 to $2 million. The panel price is not the equipment price.
Important questions
Know what to expect.
How do I use this as a fence cost calculator?+
Enter the length and your price per panel or per picket. The cost line is that material only. Posts, concrete, rails, gates, and labor are extra.
Why are there more posts than panels?+
Each panel sits between two posts, and the ends of the fence each need a post. Shared posts between panels are why the post count is panels plus one, not panels times two.
What gap should pickets use?+
The default is 0.5 inch between 3.5 inch pickets. Use the spacing you want. A board-on-board fence overlaps, so this gap method does not describe it.
Does the calculator include rails?+
No. Two or three rails per section is typical and depends on the fence height and style. Multiply sections by rails yourself if you need that tally.
