使用Java编写的贷款计算小程序,支持等额本金和等额本息方式,可列出详细的还款计划
totalPayedPrincipal = totalPayedPrincipal.add(payPrincipal);
BigDecimal interest = totalLoanMoney.subtract(totalPayedPrincipal).multiply(loanRateMonth).setScale(2, BigDecimal.ROUND_HALF_EVEN);
这里在算利息之前,先把totalPayedPrincipal加上了本月应还本金。导致在计算第一个月的利息时,totalPayedPrincipal不是0。因此还款计划的利息整体向后推了一个月。
累积已还本金 = 贷款本金/总还款月数*已还款月数
BigDecimal totalPayedPrincipal = payPrincipal.multiply(new BigDecimal(i));
