A fence post calculator is the first line of any fence take-off, because the posts set the concrete, the rails and the labor that follow. The count is the run divided by the spacing plus one, with corner and gate posts added by hand as the crew lays the job out, and it moves every time a customer asks for a different spacing or a different gate. This page works the post count and the concrete for the common runs, shows how a chain link fence calculator differs from a wood one, and points at the free fence estimate tool on this site that derives the posts from the spacing and prices the run from the contractor's own costs, markup and labor rate. No figure here is a market price.
Posts from the spacing, plus one for the end
Run divided by spacing plus one: 160 feet at 8 foot spacing is 21 line posts, at 6 foot spacing it is 28. Every corner adds a post where the run turns, and every gate adds two, so a 160 foot run with two corners and one gate at 8 foot spacing sets 25. The tool derives the line count from the spacing you enter so the materials line moves when the spacing does, and takes the gates as a count of their own.
Concrete from the post count
Each post takes a hole and the concrete to fill it around the post, and the take-off usually carries it as bags per post: at two bags a post, 21 posts is 42 bags; at three, 63. The tool carries the concrete inside your cost per post set, so the post line already includes what it costs you to set it, and a change in the spacing changes the concrete with the count instead of leaving it behind.
Chain link: line posts, terminal posts and the fabric by the foot
A chain link fence calculator counts the same line posts from the spacing, usually 10 feet, and adds terminal posts at every end, corner and gate, which are heavier and set deeper. The fabric, the top rail and the tension wire are priced by the linear foot. On a 160 foot run at 10 foot spacing that is 17 line posts plus the terminals, and the tool prices the material per foot and the posts each from your own costs.
From the post count to the estimate the customer signs
Posts, material per foot, gates each, labor per foot and removal make the estimate, and the free fence estimate tool works every line from the contractor's own figures and ends on the price per linear foot. TakeoffDeck Pro keeps every estimate against the customer and the job, so the post count that was quoted is the one the crew sets. This page publishes no post or concrete price: the figures are the contractor's.
Questions people ask about fence post calculator
How many fence posts do I need for 100 feet?
At 8 foot spacing, 100 divided by 8 plus one is 13.5, so 14 line posts, plus a post at each corner and two at each gate. At 6 foot spacing it is 18 line posts.
How much concrete per fence post?
The take-off usually carries two to three bags per post depending on the hole; the tool carries it inside your cost per post set so the concrete moves with the count.
Does the chain link fence calculator price the fabric?
The fence estimate tool prices the material between posts per linear foot at your cost, which for chain link is the fabric, top rail and tension wire together, plus posts each and gates each.
