Neg Am Mortgage Calculator

Managing finances can be a daunting task, especially when it comes to mortgages. For those considering or currently holding a negative amortization (Neg Am) mortgage, understanding the financial implications is crucial. To simplify this process, a Neg Am Mortgage Calculator proves to be an invaluable tool.


The formula used to calculate the monthly payment for a negative amortization mortgage is derived from the standard mortgage formula. It incorporates the loan amount, interest rate, and loan term to determine the monthly payment. The formula takes into account the negative amortization feature, which allows for a minimum payment that may not cover the full interest due, resulting in the remaining interest being added to the loan balance.

How to Use:

  1. Enter the loan amount, interest rate, and loan term in the respective fields.
  2. Click on the “Calculate” button.
  3. The calculator will compute the monthly payment based on the provided information.


Let’s consider a scenario where the loan amount is $200,000, the interest rate is 5% per annum, and the loan term is 30 years. Upon calculation, the monthly payment would be approximately $1,073.64.


  1. What is a Neg Am mortgage?
    • A Neg Am mortgage is a type of mortgage where the minimum payment may not cover the full interest due, resulting in the unpaid interest being added to the loan balance.
  2. How does negative amortization affect my loan balance?
    • Negative amortization causes your loan balance to increase over time, as the unpaid interest is added to the principal amount.
  3. Is negative amortization common?
    • Negative amortization mortgages were more prevalent before the 2008 financial crisis but have become less common since then.
  4. Are Neg Am mortgages risky?
    • Yes, Neg Am mortgages can be considered risky due to the potential for increasing loan balances and higher future payments.
  5. Can I make larger payments to avoid negative amortization?
    • Making larger payments can help reduce negative amortization and mitigate its effects on your loan balance.
  6. Are Neg Am mortgages suitable for everyone?
    • Neg Am mortgages are typically more suitable for borrowers who have irregular income streams or those who anticipate higher future earnings.
  7. How does the interest rate affect negative amortization?
    • A higher interest rate can accelerate negative amortization, as more interest accrues on the outstanding balance.
  8. What happens if I reach the negative amortization limit?
    • Once you reach the negative amortization limit, your loan may be recast, resulting in higher monthly payments to amortize the outstanding balance.
  9. Can I refinance a Neg Am mortgage?
    • Refinancing a Neg Am mortgage may be an option to obtain a more favorable loan structure or to mitigate the effects of negative amortization.
  10. How do I determine if a Neg Am mortgage is right for me?
