GAP Insurance Worth-It Calculator
Decide if GAP insurance is worth the cost based on your specific loan-to-value ratio and depreciation curve. GAP pays the difference between your insurance payout and your loan balance if the car is totaled — but it’s only valuable if you’re actually upside-down.

See whether GAP coverage makes sense given your loan structure and vehicle type.
How It Works
If your car is totaled, your auto insurance pays the current market value — not what you owe. If you’re upside-down by $4 000, you owe that $4 000 to the lender even though the car is gone. GAP insurance closes that gap. Cost: $200–700 from dealer (often overpriced), $20–50/year from your auto insurer (best deal).
How to Use This Calculator
- Calculate your projected negative equity by year (use the LTV calculator).
- Find your peak negative equity year and amount.
- Compare to GAP insurance cost over the same years.
- Buy from your auto insurer, not the dealer — saves 70–80%.
Worked Example
Reference Table
When GAP insurance is worth buying. Always buy from your auto insurer ($20–50/year added to policy), never from the dealer ($500–800 one-time).
| Loan scenario | GAP worth it? |
|---|---|
| 0% down, 84-month loan | Yes — high negative equity for 3+ years |
| 5–10% down, 72-month loan | Yes — 2 years of meaningful gap |
| 15% down, 60-month loan | Maybe — small gap, but premium is cheap |
| 20%+ down, 60-month loan | No — you’re even from month 6 |
| Cash purchase (no loan) | No — no loan to gap |
| Lease | Often included in lease — verify before buying separately |
| Loan + EV with rapid depreciation | Yes — even with 20% down |
| Trade-in with negative equity rolled in | Yes — already upside-down on day one |
Frequently Asked Questions
Where should I buy GAP insurance?
Your existing auto insurer. Most major insurers (State Farm, GEICO, Progressive, Allstate, USAA) offer GAP as a rider for $20–50 per year. Dealers and lenders charge $500–800 for the same coverage.
Can I cancel GAP insurance after I bought it from the dealer?
Yes. Most dealer GAP policies are pro-rated — request cancellation in writing through the lender. Refund usually arrives within 30 days. Many drivers cancel and re-buy from their insurer.
Does GAP cover voluntary surrender or repossession?
No. GAP only pays in the event of theft or total-loss collision. Voluntary actions and repossessions are not covered.
Is GAP insurance the same as new-car replacement?
No. GAP closes the gap between insurance payout and loan balance. New-car replacement (a separate optional coverage) pays for a brand-new equivalent vehicle if your less-than-2-year-old car is totaled. Both have value but are separate products.
When can I cancel GAP if I have it?
Once your loan balance drops below the car’s value (you’re no longer upside-down), you no longer need GAP. Run the LTV calc every 6 months and cancel as soon as you cross under 100% LTV.
