#### Formulas Used
DIY Expected Treatments per Year: DIY_Treatments/yr = Baseline_Treatments × Severity_Multiplier ÷ DIY_Success_Rate
DIY Cost per Treatment: DIY_Cost/Treatment = (Product_Cost × SqFt_Factor) + (Hours × Hourly_Rate)
DIY Total Cost (over N years): DIY_Total = Equipment_Cost + (DIY_Cost/Treatment × DIY_Treatments/yr × N)
Professional Initial Cost: Pro_Initial = Cost_per_Visit × Num_Visits × SqFt_Factor
Professional Annual Retreatment Cost: Pro_Retreat/yr = min(0.95, (1 − Pro_Success_Rate) × Severity_Multiplier) × Cost_per_Visit × SqFt_Factor
Professional Total Cost (over N years): Pro_Total = Pro_Initial + (Pro_Retreat/yr + Annual_Contract) × N
Expected Damage Risk Cost: Damage_Risk = Base_Damage_Cost × Severity_Multiplier × (1 − Success_Rate) × N
Risk-Adjusted Total: Total_Risk_Adjusted = Direct_Total + Expected_Damage_Risk
SqFt Factor: SqFt_Factor = max(1.0, Home_SqFt ÷ 1,500) — costs scale proportionally above 1,500 sq ft baseline.
