16.计算报酬率再看看我们在本章开头所讨论的TMCC证券:
a.基于24099美元的价格,TMCC所付的借款利率是多少?
b.在2020年3月28日,该证券的价格是38260美元。如果一个投资者在发行之初以24099
美元买得,并在这一天卖出,那么她所赚取的年报酬率是多少?
c.如果一个投资者在2020年3月28日买入该证券,并一直持有至到期,那么她所赚取的年
报酬率是多少?

Solvingforrweget:
r=(FV/PV)1/f-1
a.PV=$100.000/(1+r)30=$24.099
r=($100,000/$24.O99)1/30-1=.0486or4.86%
b.PV=$38.260/(I+r)12=S24.099
r=($38,260/S24.099)1712-1=.0393or3.93%
c.PV=$100,000/(I+r)18=$38,260
r=(S100,000/$38"260)""-1=.0548or5.48%
17.计算现值假定你仍然希望拥有一辆价值170000美元的法拉利(见第9题)。如果你相
信你的共同基金可以达到12%的年报酬率,而且你想在9年后,当你满30岁时购买这辆汽车,
那么,现在你必须投资多少钱?
TofindthePVofalumpsum.weuse:
PV=FV/(l+z/
PV=S170.000/(1.12)9=$61.303.70
18.计算终值你刚将第一笔4000美元存入你的个人退休金账户。假定你可以赚取11%的报
酬,而且不再追加任何存款,那么,45年后你的账户将有多少钱?如果你在10年后才存进
这笔钱呢?(这个建议是一项投资策略吗?)
TofindtheFVofalumpsum.weuse:
FV=PV(1+r)f
FV=$4,000(1.11)45=$438,120.97
FV=$4,000(1.11)35=$154.299.40

20.计算期数你预计将在2年后毕业时收到10000美元。你计划以10%的利率将这笔钱再投
资,直到你拥有
75000美元。请问,从现在开始,你还要等多长时间?

58.计算年金值你在考虑购买一辆新车,你既可以租这辆车,也可能用一笔3年期贷款购买
它。你想买的这辆车价值32000美元。经纪商有一项特别的租赁安排,你今天付99美元,
并在接下来的3年中每个月支付450美元。如果你购买这辆车,你将要在接下来的3年中以7%
的APR按月还款。你相信你能在3年后以23000美元的价格把这辆车卖出去。你是应该购买
这辆车,还是应该租赁?要想使购买和租赁没有什么区别,你在3年后转卖这辆车的价格应
该是多少?
答案:租赁付款的PV=14672.91美元购买的PV=13345.18美元保本点转卖价格=21363.01美元

66.计算年金付款额这是一个典型的退休问题。使用时间线可以帮助你了解这个问题。今天,
你的朋友正在庆祝她的35岁生日。她想开始为她预期在65岁退休而储蓄。她希望在退休后的20
年间,每年生日时都能从储蓄账户中提取105000美元。第1次提款将在她66岁生日时。你的朋
友想把钱放在当地的信用合作社,年利率是7%。她想在每次生日时都存入一笔等额的钱,作为
她的退休基金。
a.如果她从36岁生日开始存款,一直到65岁(最后一笔存款的时间是65岁生日),那么,她每
年必须存入多少钱,才能实现她的退休计划?
b.假定你的朋友刚继承了一大笔遗产。她决定不再每年存入等额的钱,而要在35岁生日时存入
一大笔钱,以实现她的退休计划。她应该存入多少钱?
c.假定你朋友的老板愿意每年贡献1500美元到这个储蓄账户中,当做公司分红计划的一部分。
此外,你的朋友预期在她55岁生日时,可从一家家庭基金领到150000美元,她也将把这笔钱存
入退休金账户中。现在,她每年应该存入多少钱,才能满足她退休时所需要的提款?

19.修正内部收益率法SlowRide公司采用以下现金流资料来评估某个项目:
(金额单位:美元)
年份现金流
0-16000
16100
27800
38400
(续)
年份现金流
46500
5-5100
公司所有项目采用10%的利率,运用全部三种方法计算项目的修正内部收益率。

22.现金流量直觉一个项目的初始成本为I,必要报酬率为R,每年支付C,共N年。
a.用I和N来表示C,使得项目的回收期正好等于它的年限。
b.用I、N和R来表示C,使得在NPV决策法则下,这是个有利可图的项目。
C.用I、N和R来表示C,使得项目的成本效益比率等于2。
a.Tohaveapaybackequaltotheproject'slife,givenCisaconstantcashflowforNyears:

b.TohaveapositiveNPV.I<C(PV7FA^«.y).Thus.C>I/(PVIFA^®
c.Benefits=C(PVIFAR%@=2xcosts=21
C=2I/(PVIFA^.y)
26.内部收益率法的问题某项目的现金流情况如下:
(金额单位:美元)
年份现金流
058000
1-34000
2-45000
该项目的内部收益率是多少?如果要求回报率为12%,公司应接受该项目吗?该项目的净现
值是多少?如果要求回报率为0%,该项目的净现值是多少?如果要求回报率为24%,该项目
的净现值是多少?这之间有什么关系?回答问题时,不妨绘制NPV图。
