How much can a new car depreciate within one year?

A new car can depreciate by approximately 20% to 30% within its first year of ownership. This rapid depreciation is primarily due to factors such as the transition from new to used status, market demand, and mileage accumulated. For example, if a car is purchased for $30,000, it could lose around $6,000 to $9,000 in value within that first year.
