计算说明

提前还款改变的是尚未发生的利息。已经付过的利息不会退回。一次性还清时，需要准备的现金是剩余本金加上违约金。

缩短年限尽量维持原来的月供，让期限变短；减少月供则把剩余期限留住，把每月压力降下来。等额本金在缩短年限时，按原来的每月本金继续归还。

公式

剩余本金取自原还款计划。缩短年限时保持等额本息月供不变，反推新期数；减少月供时保持剩余期数不变，重算月供。

使用时注意

违约金 = 本次提前归还本金 × 违约金比例。比例填 0 表示合同没有违约金。
少付利息没有做折现，只是名义差额。

常见问题

缩短年限和减少月供哪个省利息？

同样的提前还款金额，缩短年限通常省下更多名义利息，因为剩余本金被更高的月供更快消化。减少月供则优先改善每月现金流。

已还期数怎么填？

按实际已扣款的期数填。填 12 表示原计划已经走完 12 期，从第 13 期的剩余本金开始试算。

违约金从哪里扣？

本工具把它视为额外现金支出，不把它加进贷款本金。页面上的「扣除违约金后的利息差额」用来看这笔支出能不能被少付的利息盖住。
