prepayment

This term describes a financial transaction where the exchange of value occurs before the delivery of a product or the completion of a service. It carries a connotation of security for the seller and a commitment of trust or risk for the buyer, often appearing in formal commercial contracts or service agreements.

In the context of lending and mortgages, the word shifts toward a strategy of debt reduction. Here, it refers to an intentional acceleration of payment to minimize interest accrual over time, distinguishing it from the standard scheduled installment.
