Gap insurance: how it works and when it's worth it

Gap insurance pays the difference between what you still owe on a car loan or lease and what your insurer pays for the car if it's totaled or stolen. It's worth having only while you owe more than the car is worth, and buying it from your auto insurer often costs much less than buying it at the dealership.

How gap insurance works

When a car is totaled or stolen, collision or comprehensive coverage pays its actual cash value: what the car was worth just before the loss, after depreciation, minus your deductible. New cars lose value quickly, and loans are paid down slowly, so for the first few years many drivers owe more than the car is worth. That difference is the "gap," and gap insurance pays it so you aren't left making payments on a car you no longer have.

Gap only works alongside collision and comprehensive coverage. If you don't carry those, there's no insurance payout for gap to top up.

An example

Some gap products also cover the deductible; most insurer gap does not. Check the terms.

What it does not cover

• Your collision or comprehensive deductible (usually).
• Late fees and past-due payments. Missed payments can also void some gap contracts.
• Extended warranties, service contracts and other add-ons financed into the loan.
• Repairs. Gap pays only after a total loss or theft.

Where to buy it

There are two different products sold under the gap name:

• Gap coverage from your auto insurer is added to your policy as an endorsement. Washington's insurance regulator notes it usually adds only a small amount to your premium and can be cancelled.
• GAP waivers or debt cancellation agreements from a dealer or lender are sold with the loan. The same regulator calls them often overpriced. If you roll the cost into your loan, you also pay interest on it for the life of the loan.

The Consumer Financial Protection Bureau stresses that gap is optional and you can say no at the dealership. Banks, credit unions and insurers may also sell gap you can pay for up front. Get your insurer's price before you sign the loan paperwork.

Is gap insurance worth it?

Gap makes sense when you're likely to owe more than the car is worth. That's most common if you:

• Put down less than about 20%.
• Took a long loan, such as 60 months or more.
• Rolled an old loan's balance into the new one.
• Bought a model that loses value quickly.

It's probably not worth it if you paid cash, made a large down payment, or your loan balance is already below the car's value. A quick check: compare your payoff amount with the car's private-sale value from a pricing guide.

Gap and leases

Many leases include gap coverage as a standard feature; others charge for it separately or require you to buy it. Read the lease contract before paying for gap a second time through your insurer.

Cancelling and refunds

Drop gap once you owe less than the car is worth. If you bought it from your insurer, just remove it from your policy. If you paid for a dealer or lender product up front and then sell, refinance or pay off the car early, you may be entitled to a refund of the unused portion, though some dealer waivers aren't refundable, so check the contract. The CFPB has found servicers that failed to obtain or apply refunds of unearned gap fees after loans ended early, so request the refund in writing and follow up.
