Overview

Fence cost is run length times installed price per foot, but the honest way to budget is to split that rate into its parts: the material per linear foot and the labor to install it, then add gates and posts on top. This calculator takes your numbers in that shape, because local prices are the only prices that matter for your budget.

Widely cited cost estimates commonly put installed wood fence in the $20 to $50 per linear foot band, with material on its own in the $10 to $30 range and labor adding roughly $5 to $20 on top. Vinyl and composite typically price at or above the top of the wood band, and chain link at or below the bottom, but every one of those figures changes with region, height, grade and the market at the time you buy, so this calculator lives on your inputs, not averages.

Assumptions

  • Total cost is run length times your material rate plus run length times your labor rate, with gates, posts and concrete added by the entries you make.
  • A waste factor is applied over material to cover cuts and damage.
  • The result is an estimate from your own rates, not a quote and not a regional average.

Common mistakes

  • Multiplying the run by a single "installed per foot" figure from one region and one material, then treating it as your quote.
  • Counting the gate as fence footage, when a gate adds hardware and posts instead of straight panel feet.
  • Forgetting concrete, fasteners and waste in the material line, the classic 10 to 15 percent that quietly lands on top of every take-off.

Fence calculation formulas

The same math the calculator runs, in plain terms. Nothing here is a black box.

  • Sections

    sections = max(ceil(effective run / post spacing), 1)

  • Post count

    posts = (sections + 1) along the run, minus named corner and end posts already placed, plus 2 gate posts per gate

  • Effective run

    effective run = total length - sum of gate widths

  • Rail count

    total rails = sections x rails per section

  • Picket count

    pickets = ceil(run in inches / (picket width + gap)); total = ceil(raw x (1 + waste %))

  • Board-on-board pitch

    pitch = picket width - 1 in overlap

  • Panel count

    full panels = floor(run / panel width); add 1 cut panel if the remainder is over 0.01 ft; total = ceil(raw x (1 + waste %))

  • Concrete volume

    per-hole = pi x (diameter / 2)^2 x depth; total = per-hole x posts; bags = ceil(total / bag yield)

  • Slope-adjusted run

    slope run = effective run / cos(atan(slope % / 100)); shown alongside, counts use the flat run

  • Cost

    materials = (posts x post price + rails x rail price + infill x unit price + 60 lb bags x bag price) x regional multiplier; labor = effective run x labor per ft x terrain multiplier x regional multiplier; installed total = materials + gate hardware + removal + permit + labor

Every number the calculator shows comes from these formulas applied to your inputs.

Buying guide

A fence cost estimate only means something once the run length is accurate, because every other line in the budget scales off that number. Walk the property line with a long tape or a wheel, note where corners and gates fall, and if the yard is not rectangular the fence perimeter calculator handles irregular lot shapes better than pacing off a rough guess. Once the footage is set, this fence cost calculator keyword split, run length times material rate plus run length times labor rate, mirrors how most contractors actually build a quote, so comparing what you get here against a written estimate is a fair, apples to apples check. Cost calculators across every material category live under the cost calculators hub, so if you are weighing one fence type against another before committing to a run length, that is the place to see tear-out, staining and material pricing side by side in one pass. A rough per foot figure from a neighbor or a forum post is a starting point at best, since region, current lumber prices and the specific crew doing the work all move the real number more than people expect.

Material and labor rarely move together. A pressure treated pine panel fence and a cedar privacy fence can share the same labor rate per foot because the crew sets the same number of posts and rails, while the material line alone can double. Pricing out the actual panel style first, with a tool like the wood fence calculator, gives a realistic per foot material number instead of a guess pulled from a brochure. Posts are the other variable that gets underpriced: concrete, post size and depth all change with soil and frost line, and the fence post concrete calculator and fence post depth calculator both exist because post concrete and depth are two of the most commonly skipped line items in a homeowner's first pass at a budget. Add those two totals into the post and concrete fields here rather than folding them into a generic material rate, and the total stops hiding a cost that a real contractor bid would always itemize separately.

Gates deserve their own line rather than a share of the per foot rate, since a gate adds hinges, a latch and two posts set closer together than the rest of the run, not a stretch of panel. Material choice is the other lever worth checking before the number gets treated as final: wood, vinyl, composite, aluminum and chain link all carry different installed price bands, and the wood vs vinyl vs chain link vs aluminum cost comparison and the narrower wood vs chain link cost guide both walk through why the gap exists, mostly maintenance life and raw material cost rather than installation difficulty. If the starting point is simply what does a wood fence cost before any material decision has been made, the wood fence cost breakdown is the more general reference to read first, since it lays out the per foot bands for material and labor separately before any specific product has been chosen.

Labor is usually the single biggest swing in the whole estimate, often five to twenty dollars per foot on its own, and it is the one line a homeowner can remove entirely by self-installing. That trade is not free: it costs time, tools and the risk of a mistake on post spacing or depth that a crew would not make, and the DIY vs contractor installed fence comparison breaks down where the real savings sit and where they disappear into tool rentals and redone work. Before any crew starts digging, confirm what the fence is actually allowed to be: height limits, setback from the property line and material restrictions vary by city and by HOA, and skipping that step is how a finished fence ends up needing to be moved or rebuilt to a different spec after the fact. The fence permit requirements by state guide and the HOA fence rules guide both cover the approvals that have nothing to do with the cost math but can stall or reverse a project anyway, sometimes after materials have already been bought.

A fence budget does not end at installation. Wood fencing needs a maintenance coat on a cycle, and that recurring cost is easy to leave out of a first year comparison between wood and a lower maintenance material like vinyl: price it with the fence stain calculator so the long run comparison is honest rather than skewed toward whichever material has the lower sticker price today. For a single reference that ties material pricing, labor ranges, gate and post costs and the maintenance question together in one place, the fence cost guide is the long form version of everything this calculator automates. Run the numbers here first, then use that guide to sanity check anything that looks unusually high or low against your own region's quotes before treating a number from this calculator as a final budget.

Frequently asked questions

How much does a wood fence cost per foot?

Widely cited cost estimates commonly put installed wood fences in the $20 to $50 per linear foot band: material $10 to $30 and labor $5 to $20, with height and grade swinging the number within and beyond the band. Prices also shift with the lumber and labor market over time, so enter your local rates in the calculator for a figure tied to your market rather than relying on a national range.

What is the formula for fence cost?

Take the run length in feet, multiply by your material cost per foot and your labor cost per foot, add the gate, post and concrete lines, then apply a waste factor on the material. The calculator runs that shape in plain view so the totals check with your quote.

How much does a 100 foot wood fence cost installed?

Inside the commonly cited band of $20 to $50 per installed foot, 100 feet of wood fence budgets to roughly $2,000 at the low end and $5,000 at the top, before gates and site work. Your real number depends on height, wood grade, local labor and current material prices, which is exactly what the calculator folds in.

Is vinyl more expensive than wood?

Usually yes on the panel material alone: vinyl and composite typically price at or above the top of what wood installs for, which is why the per-foot slider answers differ. The trade is maintenance, not first cost, so compare the two on lifespan and upkeep, not the receipt alone.

How much does chain link cost compared to wood?

Chain link is generally the least expensive installed option per linear foot of the common materials, often quoted below the wood band, with the fabric gauge and height as the main levers. It anchors the low end when you compare material options with the materials guide.

Should I hire a pro or DIY the fence?

The labor line ($10 to $20 per foot in the common band) is the whole question: DIY trades that saving for your time, tools and mistakes, and a pro trades it for speed and a warranty. The DIY-versus-contractor guide lays out the break-even and the risk points.

Why do quotes come in over the estimate?

Gates, post concrete, removal of an old fence, slope and access are the usual causes: they are real lines this calculator includes, that an optimistic per-foot number from a brochure does not. Let the calculator carry them and compare the pro quote line by line.

Does height change the cost per foot?

Yes, materially: taller fences use more material at the same spacing, and labor pricing commonly tick up with height as well. This calculator takes height into the take-off, so the per-foot total you see reflects the height you actually plan.
