Fence Installation Cost Calculator
Build a full fence budget from your own numbers: material, labor, gates, tear-out and terrain, minus any discount, plus a contingency buffer.
Calculator
A 200 lf fence at $25.00/lf plus labor, gates, tear-out and terrain is about $8,140.00 with 10% contingency. Enter the prices from your own quotes.
A per-foot number is fine for a first pass, but a real fence budget has moving parts: the fence material itself, labor if it is billed separately, gates, tearing out and hauling the old fence, and add-ons for slope or rocky ground. This calculator lets you enter each line from your own quotes, subtract any discount, and add a contingency buffer for the surprises every fence job seems to find.
Everything here is a number you supply, so the estimate stays correct no matter what prices do. The default 10% contingency is a labeled planning typical — dial it down for a flat, obstacle-free yard or up for a steep, rocky, or root-bound line.
Formula
The total is the sum of the line items, less any discount, scaled by the contingency:
total = (material + labor + gates + tear_out + terrain − discount) × (1 + contingency_pct)
where material = line_length_ft × price_per_lf. Contingency is applied to the whole subtotal because overruns tend to scale with the size of the job, not with any single line.
Worked example
A 200-foot fence at $25/ft material, $2,000 labor, $400 of gates, no tear-out or terrain add-on, no discount, and a 10% contingency:
material = 200 × $25 = $5,000subtotal = $5,000 + $2,000 + $400 = $7,400total = $7,400 × 1.10 = $8,140
So the installed budget is about $8,140. If your quote already rolls labor into the per-foot rate, set labor to 0 so you do not double-count it.
Reading a fence installation quote
Watch for double-counting. The single most common mistake is entering an all-in per-foot rate and a separate labor line. Decide up front how your quote is structured: either a low material-only $/ft with labor broken out, or an all-in installed $/ft with labor set to 0.
Gates are their own cost. A gate needs heavier posts, hinges, a latch and (for doubles) a drop rod — commonly $200–$600 installed apiece. Size and count them with the gate width & post calculator before you fill in the gates field.
Tear-out is unpredictable. Old posts set in concrete, chain-link buried in a hedgerow, or limited access can push removal well past the “per foot” guess. If you are replacing an existing fence, price removal and new build together in the removal & replacement calculator.
Terrain is a real add-on. Slopes require stepped or racked panels and more posts; rock, roots and clay slow digging. A flat, clear yard needs none of this — a hillside can add meaningfully to labor. Keep the contingency higher when the ground is uncertain, and always call 811 to locate utilities before anyone digs.
