What Is Gap Insurance?

Gap insurance (short for guaranteed asset protection) covers the difference between your car’s actual cash value (ACV) and the remaining balance on your auto loan or lease if your vehicle is totaled or stolen. Your standard comprehensive or collision coverage pays out your car’s ACV, not what you still owe the lender. If those two numbers don’t match, you’re responsible for the difference.

Gap insurance covers two primary scenarios:

• Total loss: Your car is totaled when repair costs exceed the vehicle’s ACV.
• Theft: Your vehicle is stolen and not recovered. Comprehensive coverage pays ACV; gap coverage pays whatever remains on the loan.

Gap insurance works by bridging the financial shortfall that occurs when your car's ACV is less than your loan balance. Say you bought a vehicle for $32,000, financed the full amount, and two years later your car is totaled. Your insurer values the car at $22,000. That's what your comprehensive or collision policy pays, minus your deductible. But you still owe $26,000 on the loan. Without gap coverage, you'd pay the remaining $4,000 out of pocket on a car you can no longer drive.

With gap insurance, that $4,000 shortfall is covered. Here's how the math works in practice:

Keep in mind that gap insurance only pays after your primary auto insurance pays its portion. You must have comprehensive or collision coverage in place for gap insurance to apply. If your policy doesn't include the coverage that applies to the loss (for example, you don't carry comprehensive and your car is stolen), gap insurance won't pay out.

You still pay your standard comprehensive or collision coverage deductible when filing a gap insurance claim. Gap insurance doesn’t waive the deductible. It covers the difference between your ACV payout and your loan balance. If your insurer pays $21,500 after applying a $500 deductible, your gap policy covers the gap between $21,500 and whatever you owe, not the $500 you paid out of pocket.

Some gap insurance policies, particularly those sold by dealerships, include a deductible waiver that reimburses your deductible amount, up to a set limit, usually $1,000. Standalone gap policies from auto insurers like GEICO, Progressive and Nationwide typically do not include this feature, so ask specifically when purchasing.

Gap insurance is worth buying when there’s a gap between value and loan balance, a situation called being “underwater” or “upside down” on your loan. This happens most often in the first two to three years after purchase, when depreciation is fastest and loan paydown is slowest.

At $20 to $40 per year on your auto policy, gap insurance is affordable protection during the window of highest risk. Once your loan balance drops below your car's ACV, contact your insurer to cancel it. You can confirm your car's current market value at any time through Kelley Blue Book or NADA Guides.

Gap insurance protects you from owing money on a car you no longer have, a real risk for most new-car buyers in the first two to three years of a loan. At $20 to $40 per year through your auto insurer, it's one of the most affordable add-ons available. If you financed more than 80% of your vehicle's value or have a loan term of 60 months or more, buy it when you purchase the vehicle and cancel it once your loan balance falls below what the car is worth.
