Extended Warranty Break-Even Calculator
Weigh an extended car warranty against likely repair bills to see whether it pays off — and the repair cost you’d need to break even.
How it works
Cost with warranty = price + deductible × visits · Net = expected repairs − cost with warranty · Break-even = cost with warranty
An extended warranty pays off only when the repairs it covers exceed its full cost — the sticker price plus every deductible you would pay. The break-even figure is that total: if you genuinely expect more than this in covered repairs, the warranty saves money; if not, self-insuring by banking the premium tends to win, because warranties are priced to be profitable for the seller on average. The honest inputs are the ones dealers gloss over: how many claims you will actually make and how much of each is truly covered after deductibles and exclusions.
Worked example
A $2,000 warranty with a $100 deductible over three expected visits costs $2,300 all-in. If you would otherwise spend $2,800 on those repairs, you save $500. But if likely repairs are only $1,500, you lose $800 versus paying out of pocket.
Frequently asked questions
Are extended car warranties worth it?
On average they are priced so the seller profits, so most buyers pay more than they claim back. They can make sense for a model with known expensive failures or if a large surprise bill would be a genuine hardship — otherwise banking the premium as a repair fund usually wins.
What does the break-even number mean?
It is the total repair bill you would need the warranty to cover — including its price and your deductibles — before it saves you a dollar. Below that amount you would have been better off paying for repairs yourself.
What isn’t covered?
Wear items like brakes, tires, wipers and often batteries are usually excluded, along with maintenance. Read the contract for the covered-component list and any per-visit deductible, since those drive the real cost.
