How much does GAP insurance cost in 2026?

TR By Tasha Reyes · Reviewed by the BudgetAutoRates editorial team Updated July 2026 7 min read

Key takeaways

  • From your insurer: $2 to $5 a month added to full coverage
  • From the dealer: $400 to $700 flat, usually rolled into the loan (so you pay interest on it)
  • Worth it when you owe more than the car is worth; cancel it the day you don't

What GAP insurance actually covers

Total your financed car and your insurer pays what the car was worth, not what you owe. If you owe $28,000 on a car now valued at $22,000, that $6,000 difference is yours to eat. GAP (guaranteed asset protection) pays it instead.

That's the whole product. No deductible help, no rental car, no repairs: just the loan-versus-value gap after a total loss or theft.

What it costs, by seller

Where you buyTypical costCatch
Your auto insurer$2 to $5 / moRequires comprehensive + collision on the policy
Your lender or credit union$200 to $400 one-timeOften cheaper than dealers; ask before signing
The dealership$400 to $700 one-timeRolled into the loan, so you pay interest on it

Sample figures for layout purposes; production ranges come from the quote-sample methodology.

The math is rarely close. Three years of insurer-added GAP at $4/mo is $144. The same protection from a dealer, financed at 9% APR over 60 months, ends up north of $850.

When it's worth it

And the flip side: once your loan balance drops below the car's value, GAP protects nothing. Check the balance against a valuation guide twice a year and cancel the moment you're above water. Insurer-side GAP prorates off your bill; dealer GAP usually needs a written refund request most buyers never send.

Carriers that include cheap GAP are buried in the quote pile. Digging is free.

Compare Quotes With GAP

How to buy it cheap

  1. Get quotes with comprehensive + collision, then ask each carrier to add GAP: the delta is your real price.
  2. If your insurer doesn't offer it, price your credit union before any dealer product.
  3. Never finance a flat-fee GAP product without computing the interest you'll pay on it.
  4. Set a reminder to re-check your loan-to-value every six months and cancel when you're above water.

GAP questions, answered

Can I buy GAP after I've had the car a while?

Usually only within a window: many insurers cap it at loans less than 2 to 3 years old, or require you to be the original owner. The dealer window closes at signing.

Does GAP cover my deductible?

No. Your regular comprehensive or collision deductible still comes out of pocket. A few carriers sell deductible coverage separately; Scout treats it as a nice-to-have, not a need.
