Mechanical breakdown insurance costs about $35 to $100 a year for most drivers, or roughly $3 to $8 a month added to a regular auto policy. GEICO charges the least, about $35 a year for its mechanical breakdown insurance, according to MoneyGeek’s 2026 car repair insurance analysis. That price is the reason this coverage keeps showing up in searches: a dealer extended warranty runs about $1,297 a year on average, according to a MarketWatch Guides analysis, so MBI costs roughly one tenth as much for similar repair protection. The catch is eligibility. Insurers only sell it on new or nearly new cars, so most drivers have a short window to buy it.
Mechanical breakdown insurance, often shortened to MBI, is an add on to your car insurance policy. It pays for mechanical and electrical failures after your factory warranty ends, minus a deductible. It is insurance, regulated by your state insurance department, which is what separates it from a dealer service contract. This guide covers what MBI costs, who can buy it, what it covers, and when it beats an extended warranty.
How much does mechanical breakdown insurance cost?
Mechanical breakdown insurance costs about $35 to $100 a year on a new or nearly new car, according to Insurance.com, with MoneyGeek’s 2026 analysis putting the range at $35 to $95 a year. GEICO is the cheapest widely available option at about $35 a year. ConsumerAffairs puts the average at about $100 a year. Your exact price depends on the car, the coverage level, and your state.
| Provider | Typical cost per year | Deductible | Eligibility window |
|---|---|---|---|
| GEICO | $35 to $85 | $250 per repair | Under 15 months old, under 15,000 miles, first owner |
| Progressive | $40 to $85 | Varies by policy | Newer vehicles, varies by state |
| Mercury | Hundreds to thousands over the contract | Varies by level | Four levels, cars up to 7 or 8 years old and 100,000 miles |
| AAA and credit unions | $35 to $95 a year in MoneyGeek’s 2026 data | Varies | Widest eligibility window of any MBI seller |
GEICO’s price is the headline number, but its eligibility window is the narrowest. Your car must be less than 15 months old with fewer than 15,000 miles, and you must be the first owner, according to GEICO’s own MBI page. In some states the window is wider, less than 36 months and under 36,000 miles. Once you buy it, you can renew it for up to seven years or 100,000 miles, whichever comes first, and up to ten years in some states. The deductible is $250 per covered repair, paid directly to the repair shop.
Mercury works differently. It sells four levels of breakdown coverage, from a basic bronze powertrain plan to a platinum plan that covers nearly everything except wear and tear items such as brakes, tires, shocks, and wiper blades. Mercury’s vice president of mechanical breakdown told Insurance.com that the price depends on the vehicle type, the contract length, the miles covered, and the protection level, and it can run from hundreds of dollars to thousands. Mercury accepts cars as old as seven or eight years with as many as 100,000 miles, so it is the option for drivers who missed GEICO’s window.
What does mechanical breakdown insurance cover?
Mechanical breakdown insurance covers repairs to most original mechanical and electrical parts of your car when they fail, after your factory warranty ends. GEICO’s MBI covers repairs to most original mechanical parts and systems, except for maintenance and wear and tear, after a $250 deductible on a covered loss. Covered parts typically include the engine, transmission, electrical system, air conditioning, steering, and fuel system. MBI only covers repairs that the manufacturer’s warranty does not cover, so there is no double coverage while the factory warranty is active.
The exclusions matter as much as the coverage. MBI does not pay for routine maintenance such as oil changes, tune ups, filters, and coolant. It does not pay for wear and tear items such as brake pads, tires, shocks, and wiper blades. It does not cover accident damage, which is what collision and comprehensive coverage are for, and it does not cover preexisting problems. In most states you must get authorization before any repair work starts, or the claim can be denied.
MoneyGeek’s 2026 analysis reports an average payout of $1,623 per breakdown for GEICO MBI claims, with claims resolved in about 3.2 days on average. That payout figure is the reason the math works for many drivers: one covered transmission repair can cost more than a decade of MBI premiums.
Mechanical breakdown insurance vs extended warranty: which costs less?
Mechanical breakdown insurance costs far less than an extended warranty. MBI runs about $35 to $100 a year, paid through your regular auto premium in small monthly amounts, and you can cancel it any time. An extended warranty, usually called a vehicle service contract, costs about $1,297 a year on average, according to MarketWatch Guides, or about $2,500 per term, according to ConsumerAffairs, and it is usually sold as a lump sum or a payment plan that ends before the coverage does.
| Feature | Mechanical breakdown insurance | Extended warranty (service contract) |
|---|---|---|
| Typical cost | $35 to $100 a year | About $1,297 a year, or $1,500 to $4,500 per contract |
| How you pay | Monthly, inside your auto premium | Lump sum or a 18 to 36 month payment plan |
| Regulated as | Insurance, by your state insurance department | Service contract, usually not insurance |
| Eligibility | New or nearly new cars only, usually under 15 months and 15,000 miles | Most cars, including older and high mileage vehicles |
| Deductible | About $250 per repair (GEICO) | $0 to $100 per visit, varies by plan |
| Cancel | Any time, like any insurance policy | Depends on the contract, often with fees |
The extended warranty wins on one point: availability. If your car is five years old with 80,000 miles, no insurer will sell you MBI, and a service contract is your only option for repair protection. If your car is new enough to qualify for MBI, the warranty is almost always the worse deal. You pay ten times as much for coverage that starts only after the factory warranty ends, which is the same window MBI covers.
Watch the payment trap with service contracts. A plan advertised at $80 a month is often a payment plan on a $2,000 to $4,500 contract, so the payments stop after 18 to 36 months while the coverage runs longer. Ask for the total contract price, the number of payments, and whether the coverage outlasts the payments before you sign anything.
Is mechanical breakdown insurance worth it?
Mechanical breakdown insurance is worth it if your car qualifies, you plan to keep it for five years or more, and you would struggle to pay a $2,000 repair bill out of pocket. The math is simple. Seven years of GEICO MBI at about $70 a year costs $490 in premiums. One covered repair at the $1,623 average payout leaves you $1,133 ahead after the $250 deductible. Two repairs in seven years, and the coverage has paid for itself several times over.
MBI is a poor buy in three cases. Skip it if your car is unreliable in ways the policy excludes, such as a model known for wear and tear failures that MBI does not cover. Skip it if you trade cars every three years, since you will sell the car before the factory warranty ends and the MBI never gets used. Skip it if you keep a repair fund of $3,000 or more in savings, since you can self insure the same risk and keep the premiums. The same keep or drop logic applies to your other coverages as the car ages, and our guide to when dropping full coverage on an older car saves money runs the same math for collision and comprehensive.
One more factor: MBI does not satisfy a lender’s coverage requirement. Your lender requires collision and comprehensive coverage, and MBI is a separate add on that covers mechanical failure, not accidents or theft. Our guide to comprehensive and collision insurance explains what your lender actually requires. If you are deciding between MBI and full coverage, full coverage comes first. Our comparison of full coverage vs comprehensive shows what each part costs.
How do you buy mechanical breakdown insurance?
You buy mechanical breakdown insurance as an add on to an existing auto policy, not as a standalone product. With GEICO, you add it online or by phone when you buy the policy or at renewal, as long as the car is still inside the eligibility window. You must be a GEICO auto policyholder first. The premium is billed through your regular premium, so there is no separate bill.
Timing is everything. The window closes at 15 months or 15,000 miles for GEICO, so check your odometer and your purchase date before you assume you can add it later. If you missed the window, ask your insurer about alternatives, or check Mercury and AAA, which accept older cars. Credit unions also sell MBI in some states, and their eligibility windows are often wider than GEICO’s.
Before you buy, ask the insurer four questions. What is the deductible per repair? What is the maximum mileage and age the coverage renews to? Does the policy require pre authorization before repairs? And which parts are excluded? The answers vary by state and by carrier, and they decide whether the policy is worth the premium for your car. If the answers do not add up, our guide to when dropping full coverage saves money shows how to weigh any coverage against what it could ever pay out.
Key takeaways
Mechanical breakdown insurance costs about $35 to $100 a year, with GEICO the cheapest at about $35 a year and a $250 deductible per repair. GEICO only sells it on cars under 15 months old with under 15,000 miles, and you must be the first owner, but you can renew it for up to seven years or 100,000 miles. An extended warranty costs about $1,297 a year on average, roughly ten times as much, for the same post warranty repair window. MBI is worth it if your car qualifies and you plan to keep it past the factory warranty, and it is a poor buy if you trade cars every few years or keep a repair fund in savings.
