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.
The next year, the car would be worth 80 percent of that two-year, $12,000 value, or $9,600. The first year tends to be the steepest drop. In fact, the moment a new car is driven off of the lot, depreciation sets in immediately.
