What is a “Negative Amortization”?
In finance, negative amortization, also known as NegAmMort, is an amortization method in which the borrower pays back less than the full amount of interest owed to the lender each month. The shorted amount is then added to the total amount owed to the lender. Such a practice would have to be agreed upon before shorting the payment so as to avoid default on payment. Also known as deferred interest or Graduated Payment Mortgage (GPM).
Negative Amortization occurs when the monthly payments do not cover all the interest owed. The interest that is not paid in the monthly payment is added to the loan balance. This means that even after making many payments, you could owe more than you did at the beginning of the loan. Negative amortization can occur when an ARM has a payment cap that results in monthly payments that are not high enough to cover the interest due or when the minimum payments are set at an amount lower than the amount you owe in interest.
