Inspection Defect Repair Cost Calculator

Estimates total repair cost based on the number and severity of defects found during an inspection, combined with labor rates and material costs.

Number of Minor Defects

Labor Hours per Minor Defect (hrs)

Material Cost per Minor Defect ($)

Number of Moderate Defects

Labor Hours per Moderate Defect (hrs)

Material Cost per Moderate Defect ($)

Number of Major Defects

Labor Hours per Major Defect (hrs)

Material Cost per Major Defect ($)

Labor Rate ($/hr)

Overhead / Markup (%)

Contingency Reserve (%)

#### Formula

Labor Cost (per severity) = Count × Labor Hours per Defect × Labor Rate ($/hr) Material Cost (per severity) = Count × Material Cost per Defect Severity Subtotal = Labor Cost + Material Cost Base Repair Cost = Σ (Minor + Moderate + Major Subtotals) Overhead Cost = Base Repair Cost × (Overhead % ÷ 100) Subtotal after Overhead = Base Repair Cost + Overhead Cost Contingency Reserve = Subtotal after Overhead × (Contingency % ÷ 100) Total Repair Cost = Subtotal after Overhead + Contingency Reserve
