Understand how principal works in amortizing loans, how payments reduce principal, and why principal reduction accelerates over time.
The principal is the foundational amount of money that you borrow from a lender. When you take out a $20,000 loan, your starting principal balance is $20,000.
In standard amortizing loans, each monthly payment is divided into interest and principal reduction. In early months, interest makes up a large portion; later on, principal reduction accelerates.
