Definition
The principal is the sum you actually borrow, before any interest. Each repayment on an amortising loan clears a slice of principal plus the interest due, so the principal falls to zero by the end of the term.
Why it matters
Interest is charged on the outstanding principal, so paying it down — or borrowing less of it — directly cuts cost. The total you repay minus the principal is the cost of credit. See amortising vs interest-only.
