Fence Cost Estimator

Estimate the total cost of installing a fence based on perimeter, material type, height, and labor rates.

Total Fence Length (linear feet)

Fence Height

4 ft 6 ft 8 ft

Fence Material

Wood (Privacy) Vinyl Chain Link Aluminum / Wrought Iron Split Rail

Number of Gates

Remove Existing Fence?

No Yes

Labor Rate ($/linear ft) optional — leave blank for estimate

#### Formula

Material Cost = Length (lf) × Material Rate ($/lf) × Height Multiplier Labor Cost = Length (lf) × Labor Rate ($/lf) × Height Multiplier Gate Cost = Number of Gates × Per-Gate Cost Removal Cost = Length (lf) × $4/lf (if applicable) Subtotal = Material + Labor + Gates + Removal Total = Subtotal × 1.10 (contingency) + Permit ($250)

Height Multipliers: 4 ft = 0.80×, 6 ft = 1.00× (baseline), 8 ft = 1.25× Post Spacing: 1 post every 8 linear feet + 1 terminal post
