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.

Frequently Asked Questions
What does GAP insurance cover?
GAP insurance pays the difference between your auto loan balance and the insurance payout (ACV) if your car is totaled or stolen. It does NOT cover repairs, mechanical breakdowns, deductibles, or rental cars. It's specifically a loan-protection product.
How much does GAP insurance cost?
Through your auto insurer (cheapest): $20-$60 per year added to your auto policy. From a credit union: $200-$400 one-time, covers loan term. From the dealer: $500-$900 rolled into the loan. Dealer GAP is 3-5x more expensive than auto-insurer GAP \u2014 never buy at the dealer.
How long should I keep GAP insurance?
Until your loan balance equals or falls below the vehicle's ACV (you're no longer 'upside down'). For a typical new-car loan with 10% down and 60-month term, that's around month 24-30. Cancel GAP once you reach positive equity \u2014 there's no value in continuing to pay.
Can I get GAP insurance after buying the car?
Yes from most auto insurers, generally within the first 1-3 years of ownership. Some insurers limit GAP enrollment to specific timeframes after purchase. The earlier you add it, the more value you get because the depreciation gap is widest in years 1-2.
Does GAP cover negative equity from trade-in?
Depends on the policy. Many GAP policies have a cap on the maximum gap they'll pay (often 125% of MSRP or vehicle ACV). If you rolled $5K of negative equity from your trade-in into the new loan, and now total the car early, GAP might not cover the full underwater amount. Read the cap carefully.
Is GAP insurance required for an auto loan?
Some lenders require GAP for high-LTV loans (low down payment + long term). It's not legally required, but it can be a loan condition. Always check loan documents and shop GAP through your insurer if required \u2014 never accept the dealer's offer at face value.
Gap insurance payoff calculator \u2014 how do I cancel dealer GAP if I already signed?
Most states give a 30-day cooling-off period for dealer GAP, and the loan paperwork itself usually specifies a cancellation procedure. To cancel: (1) request the cancellation form from the dealer's F&I office in writing; (2) submit it to the lender directly with proof of an alternative GAP policy if your lender required GAP; (3) demand a pro-rated refund. The unused premium is paid to the loan balance, not to you, which still reduces your monthly payment over time.
What if my insurance payout plus GAP still doesn't cover my loan?
Read your GAP policy cap carefully. Many GAP policies cap at 125% of vehicle ACV or MSRP \u2014 if you rolled significant negative trade-in equity into the loan or financed dealer add-ons (extended warranty, paint protection), the cap may not cover the full underwater amount. You'll owe the lender the residual. Two preventive moves: keep down payments \u2265 20%, and refuse to roll negative equity into a new loan.
