When an accident causes extensive or costly damage to your vehicle, it is possible your vehicle will be declared a total loss.
Insurance companies' total loss procedures may differ but normally they take into consideration business experience, state laws and regulations. In general, your vehicle is considered a total loss when the cost to return the vehicle to pre-accident condition would be as much, or more, than the actual cash value of the car.
There are a few variations, but typically if the cost of repairing the vehicle, plus its salvage value, plus rental reimbursement expense during repair equals or exceeds its actual cash value, it is not economically feasible to repair the vehicle will be found to be a total loss.
Many claims adjusters will find a vehicle to be totaled when the repair cost, plus the salvage value (money the insurer would recoup when selling the vehicle through a licensed salvage vendor) exceeds the vehicle's actual cash value, or if state regulations warrant the car to be totaled out.
