Extended Warranty Break-Even Calculator

A vehicle service contract is insurance, and like all insurance it is priced to make money for the seller on average. That does not make it a bad purchase — it makes it a bet on your own repair luck being worse than average, or on your inability to absorb a large bill at once.

The arithmetic below shows what has to happen for it to pay off.

Read the exclusions, not the brochure

The brochure lists what is covered. The contract lists what is not, and that list is where the money is. Common exclusions: anything classified as maintenance or wear, damage traced to a non-covered part, and failures an adjuster deems pre-existing.

Two questions that change the answer

1. Who administers it? A manufacturer-backed contract is honoured at any franchised dealer. A third-party contract depends on a company that must still be solvent when you claim.
2. Can you absorb one bad month? If a $2,500 repair would go on a credit card at 24%, the contract is buying certainty as much as expected value — and that is a legitimate reason to buy it even when the arithmetic above is negative.

The price is negotiable

Service contracts carry large margins and are routinely sold well below the first quote. Whatever you decide, do not accept the opening number, and never accept it during the same conversation as the car price.
