## 利率的影响因素
1. 社会平均利润率的高低
2. 资金市场供求对比状况
3. 借出资金的用途和使用方式
4. 借出资金期限的长短
5. 政府宏观调控政策
6. 经济周期所处阶段
## 公式总结
### 单利与复利
**单利计算公式**$It=P×i×t$
It 为利息P 为本金i 为年利率t 为时间(年)。
**复利计算公式**$F=P×(1+i)^n$
F 为终值P 为现值i 为年利率n 为计息期数。
### 名义利率与有效利率
**计息周期利率公式**$i=mr$
r 为名义利率m 为每年计息次数。
**年有效利率公式**$i=(1+r/m)^m1$
i为年有效利率。
### 终值与现值
**一次支付终值公式**$F=P×(1+i)^n$
也可表示为:$F=P×(F/P,i,n)$
**一次支付现值公式**
$$
P=\frac{F}{(1+i)^n}
$$
也可表示为:$P=F×(P/F,i,n)$
### 年金的终值与现值
**年金终值公式**
$$
F = A \times \frac{(1+i)^n - 1}{i}
$$
也可表示为:$F=A×(F/A,i,n)$​。
**年金现值公式**
$$
P = A \times \frac{(1+i)^n - 1}{i(1+i)^n}
$$
也可表示为:$P = A \times (P/A, i, n)$。
### 偿债基金
$$
A=F×\frac{i}{(1+i)^n1}
$$
A 为年金F 为终值i 为年利率n 为计息期数。
### 资金回收
$$
A=P×\frac{i×(1+i)^n}{(1+i)^n-1}
$$
A 为年金P 为现值i 为年利率n 为计息期数。
