Fortunately, depreciation does not continue at this rate, but it is still faster for new cars than for old ones. On average, a new car will lose as much as 19 percent of its value in its first year of ownership. That means that your $20,000 new car will be worth about $16,200 after just one year. With each successive year, the rate of depreciation decreases significantly. Check out the car depreciation chart to see how a new car may decrease in value over the first five years.

In 2014, used cars averaged a 12.1 percent rate of depreciation â which is to say, the average used car was worth 12.1 percent less in 2014 than it was in 2013. Black Book expects the rate of depreciation to climb to 14.5 percent in 2015.
