Is gap insurance worth it on a used car?
When gap insurance makes sense
Gap insurance pays the difference between your loan balance and your insurance payout if your car is stolen or totaled. It's most valuable when you owe more than the car is worth.
Used cars can depreciate quickly, especially if you finance for 60 months or more with little money down. In that case, gap insurance can prevent you from paying thousands out of pocket.
If you have positive equity—meaning the car is worth more than you owe—gap insurance is unnecessary. You can also drop it once your loan balance falls below the car's value.
- Consider gap if your down payment is less than 20%.
- Long loan terms (60+ months) increase the risk of being upside down.
- Cars that depreciate fast (some luxury models) benefit most.
- You can buy gap from your lender, insurer, or a third party—compare prices.
Cost and alternatives
Gap insurance typically costs a few hundred dollars upfront or adds a small amount to your monthly payment. Dealer gap can be pricey, so check with your auto insurer first—they often offer it for less.
Some insurers include gap coverage automatically if you have comprehensive and collision. Read your policy to see what's already covered.
If you decline gap, you can still protect yourself by making a larger down payment or choosing a shorter loan term.
Common mistakes
- Buying gap insurance when you already have positive equity—it's a waste of money.
- Assuming gap covers your deductible or missed payments—it only covers the difference between loan balance and actual cash value.
- Overpaying at the dealership when your insurer offers the same coverage for less.
