每月还款计划
OpenStax：贷款摊销：https://openstax.org/books/principles-finance-2e/pages/8-3-loan-amortization 介绍了定期还款如何减少贷款余额。月利率为r、还款次数为n时，还款额=本金×r/(1−(1+r)^−n)；利率为零时，用本金除以n。
每个月会先根据期初余额计入利息，再应用定期还款额和额外还款额。最后一笔还款额不会超过应付金额。金额按完整精度计算，并显示到小数点后两位。
日期和额外本金还款
第一笔计划还款为第1笔。之后的还款安排在每月同一天；必要时会调整到当月月底。日期假设每月还款未中断。
CFPB：提前还款罚金：https://www.consumerfinance.gov/ask-cfpb/what-is-a-prepayment-penalty-en-1957/ 说明了提前还款时贷款条款为何重要。本模型不包括罚金、托管账户和抵押贷款重摊。
使用方法
- 输入剩余房贷本金、利率和期限。
- 添加每月、每年或一次性的额外还款，并选择首次还款日期。
- 查看新的还清日期，并打开还款摊销表。

常见问题
每年的额外还款何时发生？
额外还款发生在第12、24、36次还款，以及之后每个12的倍数次还款。一次性还款则使用你输入的还款次数。
额外还款会降低我的常规还款额吗？
计算会保持常规本金和利息还款额不变，并缩短还款期限。不考虑重新摊销房贷。
如果我的房贷有提前还款违约金怎么办？
此估算不会扣除违约金。在依据节省额作出决定前，请查看贷款条款，以及贷款服务机构如何处理额外本金还款。
