解释:
为什么不能用18000*(1+10%)^(365*2/365) =21780
隐含意思是10%是daily compounded interest rate,不对吗?

同学你好,我不太理解你写的(1+10%)^(365*2/365)是什么意思。
但是若没有特殊说明,题目给的收益率一般都是年化收益率,所以此题中10%是年化收益率。
其实按照解释上面的方法来看是很直观的,也很好理解的。
因为这道题干写的是coumpound daily,所以
N=2*365,代表一共2年*365天=730天;
I/Y=10/365,代表把10%的年收益率转换成(10/365)的日收益率;
PMT=0;
PV=-180,000;
CPT FV=$219,846.47.

1+10%)^(365*2/365)代表知道一年的利率,求两年的收益,这样理解不对吗

这样理解是不对的哦,因为是复利计息,不是单利计息呢。

哦哦
