The bank caclulates loan interest as "simple" interest -- for every payment period, multiply the current outstanding principal by the current interest rate to determine the interest payment.
银行用“简单”利息的方法计算贷款利息-在每个还款期间,用当前未还清的本金乘以当前利率,从而计算出应付的利息。
By contrast, rules are only executed when the conditions for that rule are exactly matched as a result of other system processing (for example, applying payment against an outstanding balance).
与之相对,只有在其他系统处理(例如,为未清偿余款提供支付)导致准确匹配相应规则的条件时,该规则才会执行。
For every down-payment, after all, there is a balance outstanding.
毕竟每一种首付款,都意味着还存在未付清的款项。
