GAP Insurance Calculator
See whether GAP (Guaranteed Asset Protection) insurance makes sense based on your specific loan-to-value progression.
What GAP Insurance Covers
GAP (Guaranteed Asset Protection) insurance pays the difference between your auto loan balance and the vehicle's actual cash value (ACV) if the car is totaled or stolen. Without GAP, if you owe $32,000 but the insurance pays out only $24,000 for a totaled car, you still owe the lender $8,000 — out of pocket while you have no car. GAP closes this gap.
GAP is most valuable in the first 1-3 years of ownership when most vehicles depreciate 30-50% but the loan balance reduces only ~20-30%. New cars typically lose 20% of value the moment they leave the lot. Source: Insurance Information Institute (iii.org). Last updated: May 2026.
When GAP Insurance Pays Off
You probably need GAP if (1) you put less than 20% down on a new car, (2) your loan term is 60+ months, (3) you're financing a depreciation-prone vehicle (luxury cars, certain SUVs, electric vehicles with rapid tech obsolescence), (4) you're rolling negative equity from a trade-in into the new loan, or (5) your monthly mileage is significantly above average (high mileage accelerates depreciation).
You probably DON'T need GAP if you put 20%+ down, your loan is 48 months or less, or you're buying used (where the steep first-year depreciation has already happened).
Where to Buy GAP Insurance
| Source | Typical Cost | Notes |
|---|---|---|
| Auto insurer (Allstate, GEICO, Progressive) | $30-$60/year | Cheapest; add to existing auto policy |
| Credit union | $200-$400 one-time | One-time fee, covers full loan term |
| Dealer F&I | $500-$900 one-time | Most expensive; rolled into loan |
Almost NEVER buy GAP from the dealer — they mark up 3-5x retail. Buy from your auto insurer first, credit union second.
GAP vs New Car Replacement Insurance
GAP fills the loan-vs-ACV gap up to the loan amount. New Car Replacement (offered by Travelers, Allstate, others) pays for a brand-new equivalent vehicle if your car is totaled within the first 2-3 years. More generous than GAP but only available on newer-model cars and adds $50-$100/year. Some buyers carry both; many find one is enough.
Gap Insurance Payoff Calculator — How to Cross-Check Against the Dealer's Quote
Dealer-financed GAP is the #1 overpriced auto add-on in the U.S. — per a Consumer Financial Protection Bureau (CFPB) blog on GAP products, finance offices routinely charge $700-$900 for GAP that an auto insurer would add for $30-$60/year ($150-$300 over the typical 5-year loan). Use this calculator to compute your actual loan-vs-ACV gap, then refuse the dealer's offer in writing if it's more than 2× your insurer's quoted rate. Two protective tactics: (1) before signing the F&I paperwork, call your auto insurer to confirm they offer GAP and lock the price in writing; (2) if the dealer makes GAP a "loan condition", that may be illegal in your state — the CFPB recommends getting any conditioning offer documented in writing for later complaint. Cancel dealer GAP within the cooling-off period (typically 30 days in most states) for a full refund if you bought under pressure.
