How much does GAP insurance cost?
Two very different price tags for the same coverage. As an add-on to your auto policy, GAP insurance typically costs $50 to $150 a year, according to the Insurance Information Institute (cited by NerdWallet); Experian puts the average, citing Insure.com, near $90 a year, about $7.50 a month. Buy the same protection from a dealer or lender when you finance the car, and it becomes a flat $500 to $700 one-time charge, per United Policyholders and Experian, and because that charge is usually rolled into your loan, you pay interest on it for the whole term. All figures checked against those sources on 21 August 2026.
| Where you buy it | Typical price | How you pay | Watch out for |
|---|---|---|---|
| Your auto insurer (add-on) | $50-150 per year; ~$90 average | With your premium; drop it anytime | Requires comprehensive and collision on the policy |
| Dealer or lender (at financing) | $500-700 flat, one time | Usually financed into the loan | You pay loan interest on the fee; refunds for early payoff are on you to claim |
What dealer GAP really costs once it is in the loan
The sticker is not the cost. A financed fee accrues interest at your loan rate for the full term. Put in your numbers; the arithmetic is standard loan amortization on the added amount, nothing estimated.
True cost of that dealer GAP over the loan
Why the dealer route costs more
First, the fee itself is several years of insurer pricing collected upfront. Second, financing it means interest: on a typical 72-month loan the interest alone adds a meaningful slice, which the calculator above shows for your rate. Third, you buy protection for the entire term, but the gap between what you owe and what the car is worth usually closes within the first few years as the loan amortizes, so the later years of dealer coverage often protect nothing.
When dealer GAP still makes sense
If your insurer does not offer a GAP add-on on your policy, or a lease contract requires coverage that is bundled in, the dealer route may be the practical option. It also buys convenience: one signature at financing. Just price both routes before that signature, because the difference over a loan term is commonly several hundred dollars.

Already paid the dealer for GAP?
If you later pay off, refinance, or sell the car before the term ends, the unused part of that $500 to $700 is usually refundable, and nobody will remind you. Estimate what you are owed with our GAP refund calculator and send the demand letter it prepares.

GAP insurance cost: FAQ
How much is GAP insurance per month?
As an add-on to your auto policy, GAP typically works out to a few dollars a month: Experian cites an Insure.com average of about $90 a year, roughly $7.50 a month. Dealer GAP is not priced monthly: it is a one-time $500 to $700 charge, usually rolled into the loan, so you pay interest on it too.
Is GAP insurance cheaper from my insurance company or the dealer?
Almost always cheaper from your insurer. Insurer add-on pricing runs $50 to $150 a year (Insurance Information Institute, via NerdWallet), while dealers and lenders charge a flat $500 to $700 (United Policyholders, via NerdWallet). Financing the dealer charge adds interest on top.
Why is dealer GAP so much more expensive?
Three reasons stack up: the flat fee itself is higher than a yearly add-on, the charge is usually financed so you pay loan interest on it, and you pay for the whole term upfront even though the "gap" between loan balance and car value typically closes after the first few years.
Can I cancel dealer GAP and get money back?
Often yes. If you paid off, refinanced, or sold the car before the loan term ended and your GAP was cancellable, the unused portion is usually refundable. Use our GAP refund calculator and demand letter to claim it.
Do I need GAP insurance if I have full coverage?
Full coverage pays your car's actual cash value at the time of loss, not your loan balance. If you owe more than the car is worth, which is common early in a loan with a small down payment, that difference lands on you. GAP exists to cover exactly that difference.
