The repayment of principal from scheduled mortgage payments that exceed the interest due. The scheduled payment is the payment the borrower is obliged to make under the note. The scheduled payment less the interest equals amortization. The loan balance declines by the amount of the amortization, plus the amount of any extra payment. If such payment is less than the interest due, the balance rises, which is negative amortization.

On an FRM, the fully amortizing payment is calculated at the outset and does not change over the life of the loan.
