什么是年金终值系数
年金终值系数指固定的间隔时间相等的期间(如以年为单位)分期支付(存入)1元金额,经过若干年后按复利计算的累计本利之和。
年金终值系数公式如下:
年金终值系数(Future value of an annuity factor)=F/A=(F/A,i,n)
这里F/A=(F/A,i,n)代表年金终值系数,i代表利率,n代表年数。
年金终值系数公式的推导
该公式可由复利公式推导出来,推导过程如下:
第1年存入1元到第n年的本利和 = (1 + i)n − 1
第2年存入1元到第n年的本利和 = (1 + i)n − 2
……
第(n-1)年存入1元到第n年的本利和=(1+i)
第n年存入l元 = (1 + i)0
因此,各年本利和相加得:
An | i = (1 + i)n − 1 + (1 + i)n − 2…… + (1 + i) + 1 (1)
两边乘以(1+i),则
(1 + i)An | i = (1 + i)n + (1 + i)n − 1 + …… + (1 + i) (2)
(2)-(1)得iAn | i = (1 + i)n − 1,即
年金终值系数的应用实例
例:按年利率lO%计算5年的年金终值系数如下:
为了方便年金终值系数的运用,对不同年数不同利率分别计算出年金终值系数,列示成年金终值系数表。亦称“1元普通年金终值表”。运用年金终值系数求等额支付若干年后的年金终值就很方便。
例:每年存入银行100元,按年利率l0%复利计算,第5年后的本利和(用A表示)为多少?计算如
