Report Abuse. Hello, Yes, 'biannual' means twice a year. It is biennial (note the spelling is ONE letter different!!!) that means every two years. You can also use the term semi-annual for twice a year. Now I was ready to tell you different and then I looked it up in this source: http://www.bartleby.com/68/34/834.html. This is always a great source for many language questions: www.bartleby.com --I was using the 'usage' section for this question.
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.
Over the first five years of its life the average new car will depreciate 65 percent in value according to Kelly Blue Book. That means if you purchase the average $20,000 new car today, it will be worth around $7,000 when you go to sell it five years from now.
