Loan basics

Principal

Also known as: loan principal

The amount of loan balance you still owe, not including interest.

Principal is the unpaid balance of your mortgage. Each payment typically covers interest first, then reduces principal. Extra payments applied to principal can shorten the loan and reduce total interest paid over time.
