Negative Amortization
A loan condition where the principal balance increases over time because periodic payments are less than the interest due.
Negative Amortization
Negative amortization, also known as "NegAm" or deferred interest, occurs when the payment structure of a loan allows for payments that are insufficient to cover the periodic interest charges, resulting in an increasing principal balance over time.
Core Mechanics
The fundamental process involves:
- Monthly payments lower than required interest
- Unpaid interest being added to the principal
- compound interest working against the borrower
- Growing loan balance despite regular payments
Common Applications
Mortgage Products
Negative amortization is most frequently associated with:
- adjustable rate mortgage loans
- Payment option ARMs
- graduated payment mortgage structures
These products often start with artificially low payments that increase over time, potentially creating payment shock for borrowers.
Risks and Considerations

- Difficulty refinancing
- Extended repayment periods
For Lenders

Alternative Structures
More conventional loan structures include:
- fixed rate mortgage
- Standard ARMs
- bi-weekly mortgage payments
