问题如下:
Mary has a separate account for her annual savings which has a stated annual rate of 3% and compounding quarterly. At the end of each year, she transfers unequal cash flows into this account. Year 1: $500, Year 2: $800, Year 4: $300, Year 5: $500. How much will Mary save for her account at the end of year 5?
选项:
A.$2246.81
B.$2247.65
C.$2281.00
解释:
B is correct.
CF0=0,CF1=500,CF2=800,CF3=0,CF4=300,CF5=500,I=3.03,CPT NPV=1935.84,然后复利到第五年即为2247.65
但这道题不需要这么做,因为要求的是FV,而不是(N)PV,按照答案解析的方法做就可以。
提问:为什么I是3.03
