Glossary · The loan itself
In short
Unpaid principal is the portion of your original loan amount that you still owe, excluding any accumulated interest. This is the balance on which interest is calculated.
Each loan payment you make is split between interest and principal. Early in the loan term, more goes to interest; later, more reduces the unpaid principal. Understanding this amortization schedule helps you track your actual debt reduction over the loan's life.
