If your financed vehicle were totaled today, would standard insurance actually cover what you still owe? This calculator shows the potential financial gap GAP insurance is designed to cover.
Gap Amount = Vehicle Loan Balance - Estimated Actual Cash Value
Example
$28,000 remaining loan balance, $22,000 estimated actual cash value:
Gap Amount = 28,000 - 22,000 = $6,000
Why This Gap Exists
Standard auto insurance only pays out a totaled vehicle's actual cash value - its depreciated market value at the time of loss, not the original purchase price or remaining loan balance. Since vehicles typically depreciate faster than most loans amortize in the early years of ownership, especially with a small down payment or a long loan term, this creates a real gap between what you'd receive from insurance and what you still owe the lender.
Who Typically Needs This Coverage
GAP insurance is most commonly recommended for buyers who financed with less than 20% down payment or a loan term longer than 60 months - both factors that widen and prolong the window during which loan balance exceeds actual vehicle value, making this coverage gap a genuine financial risk rather than a hypothetical one.
