你每個月必須支付500美元,來償還助學貸款,還需要支付四年,假設貸款利率為9%APR(
每月計息一次)。現在你考慮今天要多還100美元(也就是在必須支付金額之外,再多還100
美元),此後每次還款時還是償還500美元,直到清償完畢,請問最後一期的償還金額為多
少?今天多還的100美元,其有效報酬率為多少?
答案是:
(1)
(500/0.0075)(1-1/(1.0075^48))=20092.39
20092.39-100=19992.39
(500/0.0075)(1-1/(1.0075^48))-(x/(1.0075^48))=19992.39
x=143.14
500-143.14=356.86
(2) You earn a 9% APR (the rate on the loan).
可以幫忙講解嗎?!
