Home Warranty vs. Out-of-Pocket Repair Cost Calculator

Compare the total cost of a home warranty plan versus paying for repairs out-of-pocket to determine which option saves you more money over your planning horizon.

### Home Warranty Plan Details

Annual Warranty Premium ($)

Service Call Fee per Claim ($)

Expected Claims per Year

Annual Coverage Cap ($, 0 = unlimited)

### Out-of-Pocket Repair Details

Average Repair Cost per Incident ($)

Average Major Repair / Replacement Cost ($)

Probability of Major Repair per Year (%)

### Planning Horizon

Number of Years to Compare

Annual Cost Inflation Rate (%)

#### 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).
