Fence Calculator — Material, Posts, Concrete & Cost (2026)

How much will my new fence cost? — short answer first

For a typical 150 ft pressure-treated wood fence at 6 ft tall with 1 standard gate in an MCOL region, expect $2,500-4,700 installed (about $20/linear foot including labor, posts, concrete, and permit). Vinyl at the same scope runs $4,000-6,200 — 60% more upfront but never paints + lasts 25-35 years. The calculator above runs your specific scope through AFA + RSMeans 2026 benchmarks and surfaces all five material tiers at lifetime cost-per-year.

What This Calculator Does

Drop your total linear footage, material tier, height, gates (standard + double-wide), post spacing, and regional cost zone — get post count with corners, concrete bag count, picket count, total installed cost, cost-per-linear-foot, lifetime cost-per-year, and permit + setback considerations. All five fence materials are priced in the alternatives row at lifetime cost-per-year for honest comparison.

The Math / Formulas Used

Material cost-per-linear-foot benchmarks (AFA + RSMeans 2026, installed): chain link $10-25 · pressure-treated wood $15-30 · vinyl $25-40 · composite $30-50 · wrought iron $30-70 (varies widely by ornate-vs-plain). These are full installed costs covering material + labor (typically 60/40 split — labor is higher than decks because of post-hole digging).

Concrete-per-post (1.5 cu ft for a 4×4 post in a 36" hole) is the AFA installation standard. One 60-lb premix bag yields 0.45 cu ft of finished concrete, so each post needs ~3 bags. The calculator shows total concrete bag count so you can buy with margin.

Permit + setback ranges reflect 2026 US-typical building-code variation. Most jurisdictions require permit at 4 ft+. Above 6 ft: permit + 6-12" setback from property line. Above 8 ft: often requires neighbor notification + special permit. HOAs may add design + material + height restrictions on top of municipal code.

How to Use This Calculator

1. Measure linear feet. Sum all fence runs. For a rectangular yard, perimeter. For partial fencing, only the sides you’ll fence.
2. Pick material tier. Wood for budget · vinyl for low maintenance · chain link for utility · composite for premium · wrought iron for decorative + multi-generational.
3. Set height + spacing. 4-6 ft standard residential. 8 ft+ often needs permit + setback. Post spacing 6-8 ft typical.
4. Add gates. Standard 3-4 ft pedestrian gate ($200-600 each). Double-wide vehicle gate ~1.8× standard.
5. Read the verdict. Post count, concrete bag count, total cost, lifetime cost-per-year, and permit + setback considerations.

Three Worked Examples

Example 1 — 100 ft chain-link backyard fence, 4 ft tall, 1 gate, MCOL

Posts: ceil(100/8) + 1 + 4 = 18 posts. Concrete: 18 × 1.5 = 27 cu ft ≈ 60 bags ($330). Base cost at $17.50/lf mid × 0.85 (4ft) = $1,488. Gate ~$300 mid. Permit ~$300. Total: $2,000-3,100 installed. DIY-feasible on level ground — saves 50%+. Most common backyard utility scope.

Example 2 — 200 ft PT wood privacy fence, 6 ft tall, 2 gates (1 standard + 1 double), MCOL

Posts: ceil(200/8) + 1 + 4 = 30 posts (+ 6 for gates) ≈ 36 posts. Concrete: 54 cu ft ≈ 120 bags ($660). Base cost: 200 × $22.50 × 1.0 = $4,500. Gates: $400 standard + $720 double = $1,120. Permit ~$300. Total: $5,800-8,500 installed. Vinyl alternative same scope: $7,500-11,000 — 30% premium but 25-35 yr life vs PT’s 15-20 yr.

Example 3 — 300 ft wrought iron front + side fence, 8 ft tall, 1 double-wide vehicle gate, HCOL

Posts: ceil(300/8) + 1 + 4 = 43 posts. Concrete: 64.5 cu ft ≈ 143 bags ($787). Base cost: 300 × $50/lf mid × 1.25 (8ft) = $18,750. Gate: $720 double-wide. Permit ~$400. Subtotal $20,650 × 1.35 HCOL = $28,000-42,000 installed. Cost-per-year over 75-year midpoint life: ~$465/yr — lowest cost-per-year of any material. ROI: wrought iron rarely shows visible aging at sale. Verify HOA + neighbor notification + setback rules before committing.

Common Mistakes

• Building over a property line. The worst-case fence outcome — tear-down + rebuild + legal costs. Strongly recommend a property survey ($300-800) before pouring footings, especially on corner lots or lots without recent surveys.
• Skipping the permit. Most US jurisdictions require permit for fences over 4 ft ($100-500). Unpermitted fences are tear-down candidates at home sale + neighbor disputes can force adjustment. Always check before building.
• Ignoring setback rules on tall fences. Fences over 6 ft typically require setback from property line (6-12") in most jurisdictions. Above 8 ft often needs neighbor notification too. Skipping setback is a tear-back risk if neighbors complain.
• Not settling shared-fence agreements in writing. Sharing fence cost with neighbors is common but unwritten agreements lead to disputes about cost-share + maintenance + replacement timing. Write it down BEFORE building — who pays what %, who maintains, what happens if one neighbor wants to upgrade later.
• Cheaping out on post depth or concrete. Posts in shallow holes (< 30") without proper concrete (1.5 cu ft per post) lean over years and fail in wind storms. Frost-depth requirements (typically 30-48") apply in northern climates — ignoring this means tear-out + rebuild. Don’t skimp on post depth.
• Builder-grade gate on premium fence. A $30K wrought iron fence with a $200 budget gate looks wrong AND fails first (gates take the most abuse). Match gate quality to fence tier — $400-800 standard / $1,200+ for premium materials.

Methodology & Sources

Per-linear-foot installed cost benchmarks across material tiers: AFA 2026 Cost Guides + RSMeans 2026 Construction Cost Data + Forbes Home Improvement 2026 Fence Cost Guide. Installation standards (post-spacing 6-8 ft, post-hole depth 36", concrete-per-post 1.5 cu ft): AFA Installation Standards 2026. Height surcharge multipliers (0.85× / 1.0× / 1.25× / 1.5× for 4/6/8/10 ft) reflect framing complexity + safety requirements. Gate cost ranges ($200-600 standard, 1.8× for double-wide) and permit ranges ($100-500) reflect 2026 US-typical jurisdictional variation.

How to Read the Verdict

1. Under $3K — small fence, weekend job. Chain-link backyard or 50-100 ft PT residential. DIY-feasible on level ground; pro install 1-2 days.
2. $3K-$8K — typical residential fence. Most homes land here with PT wood or vinyl at 4-6 ft. Get 2-3 contractor quotes; variance of 20-40% normal. DIY possible for straight runs.
3. $8K-$18K — large yard or premium material. Composite or vinyl at 6 ft, or PT wood at 8 ft, or chain link on a large lot. Pro install only; budget 3-5 days. Verify permits + setback rules.
4. $18K+ — premium fence; verify HOA + setbacks first. Wrought iron, premium composite, or very large lot. Match neighborhood comp range; over-improvement risk on small lots. Always verify HOA + setback + neighbor agreement BEFORE pouring footings.
5. Any height > 6 ft — permit + setback mandatory. Most US jurisdictions. Above 8 ft often requires neighbor notification too. Budget contractors who say “we don’t need permits” are flagging non-compliant work.

Post-holes are concrete pours — run the concrete calc directly with the cu ft per post if you want detailed bag-count math. For DIY wood fences, the lumber calc handles board feet by species + nominal-vs-actual sizing. Building a fence as part of a deck project? Run the deck cost calc to size the full outdoor build. For a covered pergola or gazebo at the property line, the roofing calc plans the cover.
