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.
Owner costs drop over time. Our ownership costs compare the expense of keeping a new car for one, three, five, and eight years. Most people keep their new vehicles for five or eight years. But the high depreciation costs in the first year help explain why new cars are so expensive to own, so we break that out, as well.ales tax also adds to the cost of the car the first year. Cars cost less to own every year after that. For example, the average model in our study costs almost twice as much to own the first year as it does the second year.
