问题如下:
A.J. plans to pay his child's tuition fee for four years starting 15 years from now. He estimates the fees is $22,000 per year. If the saving account interestt rate is 5.5% annually, and A.J. will make payments at the end of each year, how much would A.J. put aside?
选项:
A.$3,441.23
B.$3,800.07
C.$4,009.08
解释:
B is correct.
Step 1: N = 4, FV = 0, I/Y = 5.5, PMT = 22,000, CPT PV = -77,113.30
Step 2: PV =0, N = 14, I/Y = 5.5, FV = 77,113.30, CPT PMT =-$3,800.07
可以解释一下为什么第二次的折现n=14吗?按照题目说的后付年金的pv算出来不应该就是15年年初的折现值,那第二次折现的n为什么不是15呢?二次折现的题目遇到这个n这个问题都会比较难判断,可以稍微梳理一下规则吗?
