FIRE(财务独立,提前退休)运动在近年来逐渐兴起。虽然有很多FIRE计算器可以帮助你计算出你提前退休需要多长时间,但我们很好奇地理位置对这些计算的影响。阅读我们下面的探索(或者直接跳转到FIRE计算器)。
我们能够收集到互联网上的公开数据集,并将它们拉入Metabase以帮助我们找到答案。
按国家退休所需年数 — y轴显示这些国家的平均公民达到财务自由的年数。气泡大小表示预计的净资产(单位:美元)。
观察结果
- 根据最新的个人储蓄率统计数据,东亚国家如日本和韩国的人们能够最快达到财务自由(日本为14年,韩国为25年)。这两个国家拥有最高的储蓄率。
- 尽管北美人的平均收入在世界上名列前茅,但北美人达到财务自由所需的时间最长(加拿大为55年,美国为65年)。
- 尽管一些国家为其公民提供了更好的养老金计划(尤其是在北欧和澳大利亚),但我们没有发现退休年数与养老金计划质量之间的任何相关性(养老金指数值越高越好)。我们原本认为,拥有更好养老金计划国家的居民储蓄率会较低(这里的想法是,由于他们可以依赖养老金,他们可以承受更高的消费率),但数据并不支持这一假设。
退休年数与养老金指数值。退休年数和养老金指数值之间没有相关性。
计算您提前退休所需的时间
上述计算基于国家平均水平。要更快地实现财务自由,您应该努力超过平均水平。这个计算器可以帮助您估计您达到财务自由所需的时间。
