What Is GAP Insurance? What It Covers and Who Needs It

GAP insurance, short for Guaranteed Asset Protection, pays the difference between what you owe on a car loan or lease and what your insurer pays if your vehicle is stolen or totaled.

This insurance protects both you and your lender. If you buy a car with a low or zero down payment, your loan balance when you drive the car off the lot may be greater than the value of the car. This is common on newly financed or leased vehicles.

Many people buy GAP coverage from their dealer’s finance desk, often as a lump sum rather than a monthly premium. But buying it from your own auto insurer is usually cheaper, and you can drop it once you owe less than the car’s value.

New cars can lose value fast. Most new vehicles lose about 20% of their value in the first year, according to the Insurance Information Institute (III).¹ Because of this quick drop in value, it’s easy to end up owing more money on your car loan than the car is actually worth.

If your new car gets stolen or totaled in an accident, standard collision and comprehensive coverage only pays the actual cash value (ACV) of what the car was worth on that day, not what you still owe the bank. 

For example:

1. You finance a new car for $50,000

2. Your car is stolen or wrecked after one year

3. At the time of your claim, the car is now only worth $40,000.

4. Standard insurance pays $40,000.

5. You are stuck paying the remaining balance of your loan

On newer cars, that difference can reach thousands of dollars. Many buyers do not have that kind of cash, which is why lenders often require collision, comprehensive, and GAP coverage.

With GAP insurance, your GAP policy will step in and pay the remaining value of your loan to your lender. In most cases, you’ll owe only your deductible. Some GAP policies will also pay your car insurance deductible.

Most GAP coverage falls into two categories, based on whether you financed or leased the vehicle:

There are also additional products that cover the “gap” but aren’t insurance products.

For example, a gap waiver is a debt-cancellation agreement between you and the dealer or lender, added to your finance contract. It’s simply an agreement to cancel any remaining balance above the car’s value after a total loss.

Some lenders also offer payoff or debt-cancellation features that work like GAP insurance, but are structured as loan features. 

Read contracts carefully so you know whether you’re buying insurance, a waiver, or another payoff product.

GAP insurance is worth it when a total loss would leave you owing more than your insurer would pay. It stops making sense once you’ve paid the loan down enough that you’re no longer upside down and owe less than the car’s value, since it then protects neither you nor the lender.

GAP isn’t required by law in any U.S. state. But lenders may require GAP coverage, as well as comprehensive and collision coverage, to be in force as a condition of the loan.²

Here’s a detailed look:¹

To make the most sense, GAP insurance needs to be sold at a reasonable price, relative to the risk.

You can buy GAP coverage from your dealer’s finance desk, your lender, your own insurer (as an endorsement or rider), or a standalone provider.

Here are the advantages and disadvantages of each:¹

• Your own auto insurer: Usually the cheapest; added as an endorsement to collision and comprehensive coverage and easy to drop later.

• Car dealership: Convenient at signing but usually the most expensive. The cost is rolled into the loan balance, so you pay interest on it for the loan term. It’s difficult to drop or get refunded, so you’ll be paying interest even after you’re no longer upside down.

• Bank or credit union: May offer competitive coverage or a gap waiver at loan closing. Ask whether it’s refundable.

• Standalone GAP provider: Sold online; useful if your insurer doesn’t offer GAP, though it can cost more than an endorsement on a standard car insurance policy.

If a lender or lease requires GAP, you can usually satisfy that requirement through your own insurer, a bank, or a credit union rather than the dealer’s version, so compare before defaulting to the dealer.²

Adding GAP to a policy that already has collision and comprehensive coverage typically only adds about $20 a year, according to the III.¹ Your exact cost depends on the vehicle, loan amount, location, and where you buy.

Dealer- or lender-sold GAP is usually a one-time charge rolled into your loan, so you pay interest on it for the life of the loan, sometimes years after you’re no longer upside down.³

Standalone GAP policies can cost several times more than an endorsement.

You can cancel GAP once you owe less than your car is worth, since a standard payout would then cover your loan balance.

To check, compare your loan payoff amount with the car’s current market value using a pricing guide such as Kelley Blue Book. Or for greater accuracy, request a written payoff quote from your lender.

How you get money back depends on how you bought it:³

•    If GAP is an endorsement on your auto policy: Ask your agent or carrier to drop it. There’s usually nothing to refund.

•    If you bought dealer or lender GAP as a one-time, upfront charge: You may be owed a prorated refund of the unused portion when you pay off, refinance, or sell the car early.³

Refund rules vary by contract and state, so check your paperwork, and request any refund you’re owed in writing.
