What is gap insurance, and do you need it?

If your car is totaled or stolen, your insurer pays actual cash value, meaning what the vehicle is worth at that moment, not what you paid and not what you owe. New vehicles depreciate sharply in the first years, and loans with small down payments or long terms amortize slowly, so it is entirely normal to owe more than the car is worth for a substantial period. Gap insurance covers that difference, which without it comes out of your pocket while you have no car.

Whether you need it is a calculation rather than a preference. Compare your current loan balance against the vehicle's actual cash value from a valuation guide. If the balance exceeds the value, you are exposed by that amount and gap coverage addresses it. Situations where the gap is typically largest: less than 20 percent down, loan terms of 60 months or longer which are now the norm, vehicles that depreciate quickly, rolling negative equity from a previous loan into the new one, and leases, where gap coverage is often included in the lease agreement and worth verifying rather than assuming.

Where to buy it matters financially. Dealers sell it at the point of sale, frequently at a marked-up flat price financed into the loan so you pay interest on it. Your own auto insurer typically offers it as an endorsement for a much smaller amount added to the premium, and some credit unions offer it inexpensively. Buying from the dealer and later realizing this is common, and gap policies are frequently refundable on a prorated basis if you pay off the loan early or sell the vehicle, which is a refund large numbers of people never claim. Drop the coverage once the loan balance falls below the vehicle's value, since it is paying for an exposure that no longer exists.
