贷款利息计算
贷款利息是指贷款人向借款人借款时所产生的费用,通常以百分比表示。贷款利息的计算方法为:利息 = 本金 × 利率 × 时间。
贷款利息计算示例
以贷款本金为 40 万元、年利率为 4.3%、贷款期限为 3 年的贷款为例,其利息计算如下:
利息 = 400,000 元 × 4.3% × 3 年 = 55,200 元
月供计算
月供是借款人在贷款期限内每月需要偿还的本金和利息之和。月供的计算方法为:月供 = 本金 × [利率 × (1 + 利率)^贷款期限] / [(1 + 利率)^贷款期限 - 1]。
月供计算示例
以上例贷款,其月供计算如下:
月供 = 400,000 元 × [0.043 × (1 + 0.043)^3] / [(1 + 0.043)^3 - 1] = 12,335.45 元
