Principal & Interest

P&I

A loan repayment that pays down both the loan balance and interest each month.

Principal and Interest is the standard home loan repayment structure where each instalment pays a portion of interest plus a portion of the principal (loan balance). Early in the loan most of the payment is interest; later most of it is principal. P&I is contrasted with Interest-Only loans where the principal is not reduced for the IO period.
