GAP Insurance Need Calculator

When a financed or leased car is totaled, your standard auto insurance pays the actual cash value (ACV) — not what you owe. If the loan balance exceeds ACV (you're 'upside down'), you owe the difference out of pocket. GAP (Guaranteed Asset Protection) insurance covers this gap. Required by most leases; often unnecessary on short-term, high-down-payment loans.

When You Need GAP

(1) Low/no down payment (<10%). (2) Loan term 60-84 months. (3) Vehicle with high depreciation (luxury, EV, high-end SUV). (4) Negative equity rolled into the loan from prior trade. (5) Any lease (most leases require GAP). If you put 20%+ down on a 36-month loan with a Toyota/Honda, skip GAP — you'll rarely be upside down.

Where to Buy

Dealer GAP: $600-$1,000 one-time. Most expensive, financed into loan (so you pay interest on the GAP fee). Avoid. Auto insurer GAP: $20-$60/year added to your auto policy. Best value if your insurer offers it. Credit union GAP: $200-$500 one-time from your loan lender. Good middle option.

What GAP Actually Pays After a Total Loss — and What It Does Not

GAP is narrower than most buyers assume, and knowing the boundary prevents an expensive surprise. It pays the difference between your insurer's actual cash value settlement and the outstanding loan or lease payoff at the moment of the loss. It does not pay your collision or comprehensive deductible unless the contract specifically includes deductible coverage, and it does not pay missed payments, late fees, negative equity rolled in from a previous vehicle beyond a stated cap, extended warranties or aftermarket add-ons financed alongside the car. It also pays nothing at all unless the vehicle is declared a total loss or stolen and unrecovered, so ordinary repairable damage is outside it entirely. Critically, GAP is secondary: it only functions if you carry comprehensive and collision cover, and a lapse in the primary policy can void the GAP claim at the moment you need it. The CFPB explains the product and the questions to ask a dealer at consumerfinance.gov. Read the contract for the deductible clause and the negative-equity cap before deciding, because those two lines decide whether the payout closes your gap or leaves part of it.

Leased vs Financed: Why the Answer Differs

The calculation above changes shape depending on how you took the car. On a lease, GAP-equivalent cover is usually built into the contract by the leasing company, and the lease agreement will say so in the insurance or casualty section — buying a separate policy on top duplicates cover you already pay for. Check the lease before buying anything. On a finance deal the risk is yours and it peaks early: a new vehicle drops sharply in the first year while the loan is still front-loaded with interest, so the gap is widest in roughly the first two years and then closes as principal payments overtake depreciation. Three factors widen it — a small or zero down payment, a term stretched past sixty months, and negative equity rolled in from a trade-in. Once your payoff falls below the vehicle's market value, GAP can no longer pay anything, which is the point to cancel and claim the unearned premium refund. Run this calculator again after any large payment or a refinance rather than assuming the original decision still holds. Updated 2026-09-15.

When to Cancel

Cancel GAP once you've crossed the break-even point where ACV exceeds loan balance — typically year 3-4 on a 6-year loan with normal depreciation. Most GAP is refundable pro-rata. Calculate annually; many people overpay by carrying GAP for the full loan term when the gap closed 2 years in.
