题目:what is the future value of an annuity that pays $100 per year at the beginning of each of the next three years, commencing today, if the cash flows can be invested at an annual rate of 10%?
答案:N=3,I/Y=10 PMT=-100,则CPT后FV=$364.10
但是我按计算器如果是这个条件N=3,I/Y=10,PMT=-100,PV=0,则CPT后FV=$671.5610
我一直不太明白什么时候需要加上PV=0或者FV=0或者PMT=0的条件来按计算器,也不知道加上与不加上为何区别那么大?anyboy can help me ?great thx! |
