一般APR是指单利,APY是将单利滚存以后的结果。两者的关系是:

APY=(1+APR / N) ^ N -1

显然,APY要比APR高一些,所以国外商业银行更喜欢用APY来忽悠储户。

书上有道题:
A bank quote  certificate of deposit (CD) yields both as annual percentage rates(APR),without compounding and as annual percentage yields(APY) that include the effects of monthly compounding.A $100,000 CD will pay $110,471.31 at the end of the year.Calculate the APR and APY the bank is quoting.
答案:
For APR,PV=100,000;FV=-110,471.31MT=0;N=12,算出APR=10%
For APY,APY=(110,471.31/100,000)-1=10.471%
这里我不明白,为什么APY是直接算出来的,我和答案的算法刚好相反,是我把题目理解错了么?各位大侠帮忙回答一下,谢谢了!
