Monthly Fixed Installment

California Association of Realtors

Updated 10-31-2026

Monthly Fixed Installment

That portion of the total monthly payment that is applied toward principal and interest. When a mortgage negatively amortizes, the monthly fixed installment does not include any amount for principal reduction and doesn't cover all of the interest. The loan balance therefore increases instead of decreasing.
