问题如下:
What is the monthly payment on a 15-year mortgage where the rate is 5% with monthly compounding and the amount borrowed is USD 100,000?
选项:
解释:
The monthly payment, X, satisfies
X/(0.05/12)×[1-1/(1+0.05/12)^(12×15)]=100,000
Solving
this gives X equal to USD 790.79.
用计算器第三行计算:
N=180,I/Y=0.4167,FV=100,000,PV=0,求PMT
最终出来的结果与答案相差较大,不能用上面的思路么?
