Formulas Used

Warranty Effective Cost (Year y):

Warranty_y = (Annual_Premium × (1+r)^(y-1))
           + (Service_Fee × Claims_Per_Year × (1+r)^(y-1))
           + max(0, Gross_Repair_Value_y − Coverage_Cap × (1+r)^(y-1))
  

Out-of-Pocket Cost (Year y):

OOP_y = (Avg_Repair_Cost × Claims_Per_Year × (1+r)^(y-1))
      + (Major_Repair_Prob × Major_Repair_Cost × (1+r)^(y-1))
  

Gross Repair Value (Year y):

Gross_Repair_Value_y = (Avg_Repair_Cost × Claims_Per_Year
                      + Major_Repair_Prob × Major_Repair_Cost) × (1+r)^(y-1)
  

Net Savings (positive = warranty wins):

Savings = Σ OOP_y − Σ Warranty_Effective_y   (summed over all years)
  

Where r = annual inflation rate (decimal).
