Lending & Interest

What Is Principal?

The original loan amount or the remaining balance you owe, separate from interest.

Definition

Principal is the actual money borrowed, before interest. On a $300,000 mortgage, your principal starts at $300,000 and decreases each month as you make payments. Each loan payment splits between principal (which reduces what you owe) and interest (which goes to the lender). Early in the loan, most of your payment is interest; later, most goes to principal. Paying extra toward principal reduces your total interest and shortens the loan.

Example

Month 1 of a 30-year, $300,000 loan at 6.5%: monthly payment $1,896, of which $1,625 is interest and only $271 is principal.
