根据您的年龄、预期寿命、储蓄率、预计支出、税率、通货膨胀、当前储蓄、投资回报和养老金收入计算您距离退休还有多少年。可视化您的收入来源和资本如何随时间变化,以规划通往财务独立的道路。
根据您的财务参数计算您距离退休还有多长时间。
退休规划是财务健康的重要方面。了解积累足够财富以舒适退休所需的时间,能够帮助个人做出关于储蓄、消费和投资的明智决策。此退休计算器通过考虑当前年龄、预期寿命、储蓄率、预期支出、税率、通货膨胀、当前储蓄、预期投资回报以及养老金等额外收入来源,估算您可以退休的年数。
该计算涉及逐年预测您的财务状况,考虑到贡献、投资增长、支出、税收和通货膨胀。
税后年净储蓄:
总年支出:
调整通货膨胀后的利率:
从 ( n = 0 )(当前年份)开始,直到 ( A + n \geq L ):
退休前:
在退休前的每一年 ( n ):
更新储蓄:
退休后:
一旦退休,您停止储蓄并开始提取:
更新储蓄:
退休条件:
如果在年份 ( n ) 时满足以下条件,则可以退休:
其中
终止条件:
如果 ( A + n \geq L ),则在预期寿命内无法退休。

退休的概念经历了几个世纪的发展。在过去,大家庭通常会支持年长成员。随着工业化的进程,养老金和社会保障制度的出现为退休人员提供了保障。20世纪末个人计算机的兴起使退休计算器的开发成为可能,赋予个人掌控退休规划的能力。如今,复杂的工具结合了复杂的财务模型,帮助用户做出明智的决策。
以下是各编程语言中展示退休计算的代码示例。
1// 将以下内容放入Excel单元格:

3// A1:当前年龄(A)
4// A2:预期寿命(L)
5// A3:每月储蓄金额(S_m)
6// A4:每月支出金额(E_m)
7// A5:税率(T)
8// A6:通货膨胀率(I)
9// A7:当前储蓄(C)
10// A8:利率(R)
11// A9:年养老金收入(P)
12// A10:希望遗留的遗产(H)

14// 年净储蓄(S_a):
15// 在单元格B1:
16// =12 * A3 * (1 - A5)
17
18// 年支出(E_a):
19// 在单元格B2:
20// =12 * A4

22// 实际利率(R_real):
23// 在单元格B3:
24// =((1 + A8)/(1 + A6)) - 1
25
26// 初始化变量:
27// 在单元格B4:
28// =A7 // 起始储蓄
29
30// 设置一个表格以迭代年份:
31// 年份在A列,从0开始
32// 储蓄在B列,使用公式计算:

34// B5:
35// =IF(A5 + A$1 >= A$2, "", IF(B4 * (1 + B$3 * (1 - A$5)) + B$1 >= (A$2 - (A$1 + A5)) * (B$2 - A$9 * (1 - A$5)) + A$10, "退休", B4 * (1 + B$3 * (1 - A$5)) + B$1))
