It is important to note that the definition of "total loss" varies among insurance companies and jurisdictions. In most cases, a car is considered a total loss if the cost to repair it after an accident exceeds a certain percentage of its actual cash value (ACV). The ACV is determined based on factors such as the car's make, model, age, condition, and mileage. If the estimated repair cost exceeds the threshold set by the insurance company (typically between 65% and 75% of the ACV), the vehicle will be declared a total loss.
