问题如下:
John receive a gift from his grandpa about $1.2 million. He plans to buy a house in five years later, which price is expected to be $250,000 at that time. How much should John deposit now if the stated annual rate is 3% and compounded monthly?
选项:
A.
$215,652
B.
$215,217
C.
$242,620
解释:
B is correct. Present value * (1+3%/12)12*5=$250,000, therefore, John should deposit $215,217 currently.
老师请问这题为什么stated annual rate不需要先转换为EAR再计算,而是直接除以12得到月度的利率?
