什么是年金现值系数

　　一定期间内每期期末等额的系列收付款项的现值之和，叫后付年金现值。后付年金现值的符号为 $P V A n$ ，后付年金现值的计算公式为：

$PVA_n=A\sum_{t=1}^n\frac{1}{(1+i)^t}$

　　式中， $\sum_{t=1}^n\frac{1}{(1+i)^t}$ 叫年金现值系数，或年金贴现系数。年金现值系数可简写为 $P V I F A i, n$ 或 $A D F i, n$ 。

年金现值系数的推

　　计算普通年金现值的一般公式为：

$P=A\frac{1}{(1+i)^1}+A\frac{1}{(1+i)^2}+\cdots+A\frac{1}{(1+i)^{n-1}}+A\frac{1}{(1+i)^n}$ ，(1)

　　等式两边同乘(1+i)

$P\times {(1+i)}=A\frac{1}{(1+i)^0}+A\frac{1}{(1+i)^1}+\cdots+A\frac{1}{(1+i)^{n-2}}+A\frac{1}{(1+i)^{n-1}}$ ，(2)

　　(2)式减(1)式

　　 $P\times (1+i)-P=A-A\frac{1}{(1+i)^n}$ ，

∴年金现值系数公式 $P/A=(P/A,i,n)=\sum_{t=1}^n\frac{1}{(1+i)^t}=\frac{1}{i} -\frac{1}{i(1+i)^n}$

∵ $(1+i)\sum_{t=1}^n\frac{1}{(1+i)^t}=\sum_{t=1}^n\frac{1}{(1+i)^{t-1}}=1+\sum_{t=1}^n\frac{1}{(1+i)^t}-\frac{1}{(1+i)^n}$

∴ $i\sum_{t=1}^n\frac{1}{(1+i)^t}=1-\frac{1}{(1+i)^n}$

∴ $P/A=(P/A,i,n)=\sum_{t=1}^n\frac{1}{(1+i)^t}=\frac{1}{i} -\frac{1}{i(1+i)^n}$

年金现值系数的值

　　有关年金现值系数值，可通过年金现值系数表查得。

　　例如，现在存入一笔钱，准备在以后5年中每年末得到100元，如果利息率为10%，现在应存入多少钱？在本例中，通过“年金现值系数”查表可得，

　　年金现值系数公式

　　 $P/A=(P/A,0.1,5)=3.790=\frac{1}{0.1} -\frac{1}{0.1\times(1+0.1)^5}$

　　 $P V I F A 10%,5 = 3.790$ ，则：

　　 $\sum_{t=1}^n\frac{1}{(1+i)^t}$ 　　

　　 $PVA_5=A\cdot PVIFA_{10%,5}$

　　 $=100\times 3.790$

　　=379
