能否先求出EAR在算FV

NO.PZ2015120604000016

问题如下:

An investor invests $180,000  today . Assume the interest rate is 10% and the investment can coumpound daily. after 2 years, the value of the investment will be :

选项:

A.

$217,800.

B.

$198,928.

C.

$219,846.

解释:

C is correct.

N = 2 × 365 ;

I/Y = 10 / 365 ;

PMT = 0;

PV = -180,000;

CPT  FV = $219,846.47

先求出EAR=10.52%,然后根据N=2,I/Y=10.52,PV = -180,000;PMT=0,FV=219.864 与答案少许有出入

同学你好,

可以。只要保证N、I/Y、PMT(如有)这三者一致,怎么算都可以。

细微的差异来自于计算过程中的四舍五入。如果EAR使用完整的10.5155.7817....,最后答案就是一样的。这种差异可以忽略不计。
