问题如下:
An investor purchased an annuity many years ago. The first payment of the annuity is to be received today. Assume the payment of the annuity is $5,000 constanly , the period the payment is 20 years. and the discount rate is 12%, calculate the today' value of the annuity:
选项:
A.$37,347.
B.$403,493.
C.$41,829.
解释:
C is correct.
Under the BGN mode.
N = 20; PMT = -5,000; I/Y =12; FV = 0; CPT PV = 41,828.89.
这道题说的是今天收到第一笔PMT,而这个年金的时间是20年,那么这道题中的今天指的是0时点还是1时点?这个表述很让人迷惑
我也可以理解为0时点就收到了第一笔5000元,然后用后付年金的功能计算的时候N就不是20,而应该是21不是吗?不然解释不通啊?
