问题如下:
You plan to set a saving account for 7 years which annual discount rate is 4% and compounded annually. Each year $500 cash is transferred into this account. What is the difference of account present value between transferring the cash at the beginning and at the end of each year?
选项:
A.$500.00
B.$120.04
C.$115.42
解释:
B is correct. If the cash is transferred at the beginning, set the calculator in the BGN mode and input data: N=7, I/Y=4, PMT=500, FV=0, then PV=-3121.07. If the cash is transferred at the end, set the calculator in the END mode and input data: N=7, I/Y=4, PMT=500, FV=0, then PV=-3001.03. Therefore, the difference between the two methods is 3121.07-3001.03=$120.04.
老師您好,想請教兩個問題,1.是否只要題目無給出FV數值,FV 就按照“0”處理?就算給了PMT,每年存錢,最終FV也都是“0”?
2.題目要求計算 每年 ordinary annuity 與annuity due的差距,即是7年中,每年的差距其實都一樣?每年供$500不管供款幾年,兩者都差$120.04?謝謝。
