Home Warranty — Annual Cost:
Age Multiplier = 1.30 if home > 20 yrs | 1.10 if > 10 yrs | 1.00 otherwise Adjusted Calls = Expected Calls × Age Multiplier Gross Repair Value = Adjusted Calls × Avg Repair Cost Effective Payout = Gross Repair Value × (1 − Denial Rate) Actual Payout = min(Effective Payout, Coverage Cap) Denied Cost = Gross Repair Value − Actual Payout Annual Cost = Premium + (Adjusted Calls × Service Fee) + Denied Cost Net Annual Cost = Annual Cost − Actual Payout
Self-Managed Network — Annual Cost:
Base Cost/Repair = Avg Contractor Cost × (1 − Discount Rate) Emergency Cost/Repair = Base Cost × (1 + Emergency Premium) Weighted Cost/Repair = Base Cost × (1 − Emerg Fraction) + Emerg Cost × Emerg Fraction Annual Repair Spend = Adjusted Calls × Weighted Cost/Repair Annual Cost = Vetting Cost + Annual Repair Spend
Comparison:
Annual Savings = Network Annual Cost − Warranty Annual Cost N-Year Total Cost = Annual Cost × Years Break-Even Calls = Premium ÷ (Avg Repair Cost × (1 − Denial Rate) − Service Fee) Coverage Adequacy = Coverage Cap ÷ Total Appliance Value × 100 Coverage Ratio = Actual Payout ÷ (Premium + Service Fees)
