汽车每年折旧多少？How fast do cars depreciate?
没有统一的官方数字。常听到的经验说法是新车第一年贬值较多（约 15–25%），之后每年约 10–15%，但这只是粗略的经验值，并非权威统计；默认的 20% 和 15% 也只是示例值。品牌、车型、里程、车况和市场年份差异很大，请参考当地二手车行情调整折旧率。There is no official figure. A commonly quoted rule of thumb is a bigger drop in the first year (about 15–25%) and roughly 10–15% a year after that, but this is a rough guide, not an authoritative statistic, and the default 20% and 15% are example values only. Brand, model, mileage, condition and market year vary widely, so adjust the rates to local used-car prices.
计算方法是什么？What method is used?
余额递减法：每年的折旧 = 年初价值 × 折旧率，第一年使用单独的折旧率，因此价值逐年下降但不会降到 0。Declining balance: each year's depreciation = start-of-year value × rate, with a separate first-year rate, so the value falls every year but never reaches zero.
