Extended Warranty Cost Calculator
Objectively evaluate retailer extended warranties and AppleCare protection plans. Calculate break-even failure probabilities and expected financial values.
Warranty Expected Value Equation
Warranty % of Product = (Warranty Price / Product Price) × 100; Break-Even Failure Prob % = (Warranty Price / Repair Cost) × 100- Cost Intensity: Retail warranties costing >15–20% of product value rarely offer positive mathematical expectation.
- Break-Even Probability: The mathematical failure probability required for warranty savings to exceed the upfront fee.
- Hypothetical Expected Value: Probability-weighted estimate of out-of-pocket repair costs compared to warranty price.

Frequently Asked Questions
Why do consumer advocacy groups generally advise against extended warranties?
Major consumer groups (like Consumer Reports) advise against extended warranties for most electronics and appliances because products rarely break during the warranty window, repair costs are often comparable to the plan price, and many credit cards provide complimentary 1-year warranty extensions.
