可能最简单的是先换算成实际年利率:
link:- 实际年利率-计算
所以,计算8%的日复利作为月利率,m
。
i = 0.08
n = 365
r = (1 + i/n)^n - 1 = 0.0832776 = 8.32776 % effective annual interest
m = ((r + 1)^(1/12)) - 1 = 0.0066882 = 0.66882 % monthly interest
equivalent to APR compounded monthly = 12 * m = 8.02584 %
而按6个月计算8%的复利作为月利率,m
:
i = 0.08
n = 2
r = (1 + i/n)^n - 1 = 0.0816 = 8.16 % effective annual interest
m = ((r + 1)^(1/12)) - 1 = 0.0065582 = 0.65582 % monthly interest
equivalent to APR compounded monthly = 12 * m = 7.86984 %
一步到位:
m = ((1 + i/n)^n)^(1/12) - 1
```。
