我现在想跟银行贷款银行答应给我百分80的生意贷款分30年期限归还。我想问下我能不能提前把贷款全部付清是不是也可以。
就是说我用20年就想把钱给还清了。这样我会省点利息的钱？

this is often allowed

need to check whether bank charge your early repayment fee or not

要看你 Mortgage 的类型及条款，track mortgage 和 offset mortgage 是肯定可以随时多还，也可以随时提前还清的。

Was it a business mortgage? Best way to find out is talking to your bank manager. Business loan/mortgage is more tailored made towards individuals so you can also negotiate.
