计算器的工作原理
COEkaki 加权溢价指数综合新加坡全部五个拥车证类别的配额溢价，以 2015 年第一轮投标结果为基准，将指数归一化为 100。
公式：
composite(round) = 0.35 × cat_A + 0.35 × cat_B + 0.1 × cat_C + 0.05 × cat_D + 0.15 × cat_E
index(round) = (composite(round) / composite(2015_round_1)) × 100指数为 180 表示，加权拥车证组合的价格是 2015 年初的 1.8 倍。每轮收到新的陆路交通管理局（LTA）数据后，指数都会重新计算。

此计算器未涵盖的项目
- 衡量价格水平，不衡量负担能力，未计入薪资、融资或GDP。
- 不区分每个类别内部的车辆细分市场。
- 选择2015年作为基期；更换基期会改变绝对数值，但不会改变相对变化。
- 这是历史指标，不是预测。
常见问题
- COEkaki 加权溢价指数衡量什么？
- 它将各类别溢价按固定权重组成的组合，与 2015 年 1 月第一轮的组合比较。页面显示持续维护的权重和基准。这不是整车价格、收入或负担能力指数。
- 为什么采用这些类别权重？
- 权重由编辑选择，并非测得的销售份额或估计的经济影响。更改权重会改变所比较的组合。我们没有为任何类别指定经验证的家庭决策影响程度。
- 可以在文章中引用该指数吗？
- 可以。请注明“COEkaki 加权溢价指数”，并链接至 coekaki.com/coe-index。计算方法公开，数值在每轮投标后重新计算。
- 这会预测未来价格吗？
- 不会。该指数是历史衡量指标，用于比较过去的溢价水平，并非预测。该指数和投标分析工具均未证明具备预测准确性。
