Fence Repair vs Replace Cost Calculator
Compare the total cost of repairing your existing fence against full replacement, factoring in fence length, material costs, labor, and remaining lifespan to find the most cost-effective option.
Total Fence Length (linear feet)
Percentage of Fence Needing Repair (%)
Repair Cost per Linear Foot ($)
Full Replacement Cost per Linear Foot ($)
Current Fence Age (years)
Expected Total Lifespan of Fence Type (years)
Expected Lifespan of New Replacement Fence (years)
Old Fence Removal Cost ($ total, 0 if none)

#### Formulas Used
Linear Feet to Repair: Repair Feet = Total Length × (Repair % ÷ 100)
Total Repair Cost: Total Repair Cost = Repair Feet × Repair Cost per Linear Foot
Total Replacement Cost: Total Replace Cost = (Total Length × Replace Cost per Linear Foot) + Removal Cost
Remaining Useful Life (Repair): Remaining Life = Expected Lifespan − Current Age
Annual Cost — Repair Option: Repair Cost per Year = Total Repair Cost ÷ Remaining Life
Annual Cost — Replace Option: Replace Cost per Year = Total Replace Cost ÷ New Fence Lifespan
Break-Even Years (when Replace > Repair upfront): Break-Even = Remaining Life × (Total Replace Cost − Total Repair Cost) ÷ Total Repair Cost
Recommendation Thresholds: • Repair ≥ 60% of fence → lean toward Replace • Annual repair cost ≥ 85% of annual replace cost → lean toward Replace • Annual repair cost < 60% of annual replace cost → Repair is clearly better
