What is gap insurance and do you need it?

Gap insurance pays what you still owe on a totaled car after the policy pays its value. When you need it, when you can skip it, and when to drop it.

Gap insurance pays the difference between your loan balance and what the car was worth the day it was totaled. Totaled means the damage is bad enough that the company pays you the value of the car instead of fixing it. You need gap only if you owe more than the car is worth.

How you end up owing more than the car is worth

A new vehicle loses value fastest in the first two years. The loan balance falls slowly over those same years, because early payments are mostly interest.

A small down payment widens that space. So does a loan of 72 or 84 months, an old balance rolled into the new loan, which is called negative equity, or dealer add ons financed into it.

Say the car was worth $22,000 the day it was wrecked and you still owe $27,000. Your policy pays the $22,000. You are left owing $5,000 on a car you no longer have.

Who should carry it

• Anyone who put less than 20 percent down.
• Loans that run 72 or 84 months.
• Anyone who rolled an old loan balance into the new one.
• Leases, where gap is often built in. Read the contract to be sure.
• Vehicles that lose value quickly.

Who can skip it

• You paid cash, so there is no loan.
• You owe less than the car is worth. A valuation guide online will tell you in five minutes.
• The loan is almost paid off.

Where to buy it

The dealer will offer it while you sign the finance paperwork. That version goes into the loan, so you pay interest on it until you cancel it.

Most auto insurers sell the same protection as an endorsement, an add on to your own policy that you can put on or take off later. Ask both what it covers and what it costs before you sign. See what else the lender requires.

What it does not do

• On most policies it does not pay your deductible, the amount you pay yourself before the insurance pays. Some versions do.
• It does not cover payments you missed or late fees.
• It does not apply if the car can be repaired. It pays only on a total loss.
• It usually stops at a set percentage of the vehicle value, so a very large balance may not be fully covered.

Cancel it when it stops mattering

Once the loan balance drops below the value of the car, gap coverage has nothing left to pay. Check once a year and drop it then.

If you bought it from the dealer, ask about a prorated refund when you pay off or trade the car. Prorated means you get back the part you did not use. Most people never ask.

That is also the time to look again at whether collision still makes sense, the coverage that pays to fix your own car after a crash.
