实现降本目的英语怎么说

"To reduce the principal" is a phrase that is used to describe the purpose of taking action to decrease the amount of money that is owed on a loan or other financial obligation. This phrase is often used in financial contexts, such as in discussions about repaying a mortgage or paying off credit card debt.
The phrase "to reduce the principal" comes from the concept of a "principal," which refers to the original amount of money that was borrowed or invested. When a person takes out a loan, for example, the principal is the amount of money that they borrow from the lender. As the borrower makes payments on the loan, the principal is gradually paid off, and the amount of the loan decreases.
Here are a few examples of how the phrase "to reduce the principal" might be used in English:
"I'm trying to pay off my mortgage as quickly as possible, so I'm making extra payments each month to reduce the principal." (我正在尽快偿还我的抵押贷款，所以我每个月都会多支付一些钱来减少本金。)
"The bank offered me a loan modification that would lower my monthly payments, but it would also extend the length of the loan and increase the total amount of interest I pay. I decided to decline the modification and stick with my original payment plan, even though it means I'll have to pay more each month. My goal is to reduce the principal as quickly as I can." (银行给我提供了一个贷款修改方案，可以降低我的月供，但也会延长贷款期限并增加我支付的总利息。我决定拒绝修改方案，并继续使用我原来的还款计划，即使这意味着我每个月要支付更多的钱。我的目标是尽快减少本金。)
"I just received a bonus at work, and I'm planning to use some of the money to reduce the principal on my car loan. That way, I can save money on interest and pay off the loan more quickly." (我刚在工作中获得奖金，打算拿出一些钱来减少我的汽车贷款的本金。这样，我就可以节省利息，并且更快地偿还贷款。)
