让我们考虑以下示例
Example: Invest $2,000 now, receive 3 yearly payments of $100 each, plus $2,500 in the 3rd year. Use 10% Interest Rate.
Let us work year by year (remembering to subtract what you pay out):
Now: PV = -$2,000
Year 1: PV = $100 / 1.10 = $90.91
Year 2: PV = $100 / 1.102 = $82.64
Year 3: PV = $100 / 1.103 = $75.13
Year 3 (final payment): PV = $2,500 / 1.103 = $1,878.29
Adding those up gets: NPV = -$2,000 + $90.91 + $82.64 + $75.13 + $1,878.29 = $126.97
Looks like a good investment.
我试图在excel中计算相同
10%
100
100
100
2500
-2000
=NPV(A1,A2,A3,A4,A5)+A6
得到了（43.78），为什么？请帮帮我
答案 0 :(得分：1)
你需要净化你的最后一年 - 100 + 2500
NPV函数假设每个单元格值是在其本年末收到的货币。
假设您在最后100美元付款后每年获得2500美元。
试试这个：
100
100
2600
NPV（.10,100,100,2600）-2000 = ~126.97
