How a Balloon Mortgage Works
Monthly Payments
You make monthly payments calculated as if the loan amortizes over the full term (e.g., 30 years). These payments are lower than a short-term loan.
Principal Reduction
Each payment reduces your principal slightly, but because the payment is based on a long term, most of each payment goes toward interest early on.
Balloon Payoff
At the end of the balloon term, the remaining balance is due as a single lump-sum payment. You must pay it off, refinance, or sell the property.
How the Balloon Mortgage Payoff Calculator Works
A balloon mortgage requires monthly payments based on a long amortization schedule (typically 30 years), but the full remaining balance must be paid off as a lump sum at the end of a shorter balloon term (commonly 5 or 7 years). This calculator shows your monthly payment, remaining balance at the balloon date, and total interest paid before the balloon is due.
Balloon Mortgage Formulas
Key Risks of Balloon Mortgages
Refinance Risk
If interest rates rise before your balloon is due, your refinance rate may be higher than your original rate, increasing your monthly payment. You may also face new closing costs.
Property Value Risk
If your property value declines, you may owe more than the property is worth at balloon time, making it difficult to refinance or sell without bringing cash to closing.
Liquidity Risk
You must have a plan to pay the balloon — refinance, sell, or have the cash ready. Without a plan, you risk default and foreclosure at the balloon date.
Frequently Asked Questions
What is a balloon mortgage?
A balloon mortgage is a short-term loan where you make monthly payments based on a long amortization schedule (typically 30 years), but the remaining balance must be paid as a single lump sum at the end of the balloon term, usually 5, 7, or 10 years. The monthly payments are lower than a standard short-term loan, but the large balloon payment is due at the end.
What happens when the balloon payment is due?
When the balloon payment is due, you must pay the remaining balance in full. Most borrowers do this by refinancing into a new loan, selling the property, or paying from savings. If you cannot pay the balloon, you risk default and foreclosure.
How is the monthly payment calculated on a balloon mortgage?
The monthly payment is calculated using the standard amortization formula based on the full amortization term (e.g., 30 years), not the balloon term. This means your monthly payment is the same as it would be on a 30-year fixed mortgage, even though the loan is due much sooner.
What is the difference between a balloon mortgage and an ARM?
A balloon mortgage has a fixed rate and a fixed monthly payment, but the entire remaining balance is due at the balloon date. An ARM (adjustable-rate mortgage) adjusts the interest rate periodically, which changes your monthly payment, but does not require a lump-sum payoff. Both carry rate risk, but balloon mortgages also carry refinance risk.
Who typically uses balloon mortgages?
Balloon mortgages are commonly used by real estate investors and developers who plan to sell or refinance the property before the balloon is due. They benefit from the lower monthly payments during the balloon period and expect to pay off the loan from sale proceeds or a new loan at the balloon date.
