Formulas: Net loan = Loan Amount − Down Payment. Monthly rate r = Annual Rate ÷ 12 ÷ 100. Amortization months n = Amort. Years × 12. Balloon months k = Balloon Years × 12. Monthly Payment (P&I) = Net × r ÷ (1 − (1+r)^−n). Interest Only payment = Net × r. Balloon Balance = Net × (1+r)^k − PMT × ((1+r)^k − 1) ÷ r. Total interest = (PMT × k) + Balloon − Net.

How to Calculate a Balloon Loan Payment
A balloon loan is structured so that monthly payments are deliberately set lower than what would be required to fully pay off the loan. The payments are calculated based on a longer amortization schedule (typically 30 years), but the loan term itself is much shorter (typically 5–10 years). At the end of the term, the remaining outstanding balance — the balloon payment — becomes due in a single lump sum.
This structure is common in commercial real estate, bridge loans, and some residential mortgages. The lower monthly payments make it easier to qualify and improve cash flow, while the balloon payment is typically handled through refinancing, a property sale, or a lump-sum payoff when the term expires.
Balloon Loan Formula
Monthly Payment = Net Loan × r ÷ (1 − (1+r)^−n)
Balloon Balance = Net × (1+r)^k − PMT × ((1+r)^k − 1) ÷ r
Where: r = monthly rate (annual rate ÷ 12 ÷ 100) | n = total amortization months | k = balloon months
Example — $300,000 loan, 6% rate, 30-year amortization, 5-year balloon:
r = 6 ÷ 12 ÷ 100 = 0.005 | n = 360 | k = 60
Monthly payment = 300,000 × 0.005 ÷ (1 − 1.005^−360) = $1,798.65
Balloon balance = 300,000 × 1.005^60 − 1,798.65 × (1.005^60 − 1) ÷ 0.005 = $279,163
Example — $300,000 loan, 6% rate, 30-year amortization, 5-year balloon:
r = 6 ÷ 12 ÷ 100 = 0.005 | n = 360 | k = 60
Monthly payment = 300,000 × 0.005 ÷ (1 − 1.005^−360) = $1,798.65
Balloon balance = 300,000 × 1.005^60 − 1,798.65 × (1.005^60 − 1) ÷ 0.005 = $279,163
Common Balloon Loan Structures
| Structure | Monthly Payment Based On | Balloon Due | Common Use |
|---|---|---|---|
| 5/30 | 30-year amortization | Year 5 | Residential & commercial mortgages |
| 7/30 | 30-year amortization | Year 7 | Commercial real estate |
| 10/30 | 30-year amortization | Year 10 | Commercial loans, investor properties |
| 3/15 | 15-year amortization | Year 3 | Bridge loans, short-term financing |
| Interest Only | Monthly interest only | End of term | Hard money loans, fix-and-flip |
Balloon Loan vs. Traditional Mortgage
| Feature | Balloon Loan | Traditional 30-yr Mortgage |
|---|---|---|
| Monthly payment | Lower | Higher |
| Loan term | 5–10 years | 15–30 years |
| Final payment | Large lump sum | Normal monthly payment |
| Interest rate | Often slightly lower | Standard rate |
| Risk | Refinance/balloon risk | Lower risk |
| Best for | Short-term ownership, commercial | Long-term home ownership |
💡 Pro tip: Always have a clear exit strategy before taking a balloon loan. The three most common exits are: (1) Refinance — replace the balloon with a new long-term mortgage before the due date; (2) Sell — use property sale proceeds to pay the balloon; (3) Lump sum payoff — use accumulated savings or investment returns. Never assume you’ll automatically qualify to refinance — credit conditions and property values may change before your balloon is due.
Frequently Asked Questions
A balloon loan has monthly payments calculated on a long amortization schedule (typically 30 years) but requires the full remaining balance to be paid as a lump sum at the end of a shorter term (typically 5–10 years). This “balloon payment” is much larger than the regular monthly payments, hence the name.
Balloon Balance = Loan × (1+r)^k − Monthly Payment × ((1+r)^k − 1) ÷ r, where r is the monthly interest rate and k is the number of balloon periods. Essentially it’s the remaining loan balance after making k monthly payments on a loan with n total amortization periods.
A regular (fully amortizing) mortgage pays off completely through equal monthly payments by the end of the term. A balloon loan has the same monthly payment calculation but the balance doesn’t reach zero — instead it comes due as one large payment at the end of the shorter balloon term. Balloon loans have lower monthly payments but higher total risk.
Balloon loans work well when you plan to sell the property before the balloon is due, when you expect significantly higher income by the balloon date, for short-term commercial real estate investments, or when lower monthly payments are essential in the short term. They are most common in commercial real estate where the typical hold period is 5–7 years.
Options include: (1) Refinance the remaining balance into a new loan before the due date; (2) Sell the property and use proceeds to pay the balloon; (3) Negotiate an extension with the lender. Failure to pay results in default and potential foreclosure. Always plan your exit strategy before taking the loan, not when the balloon is approaching.
The notation X/Y means monthly payments are calculated on a Y-year amortization schedule, but the full remaining balance is due after X years. A 5/30 balloon has payments based on 30-year amortization with the balloon due at year 5. A 7/30 has the same but balloon due at year 7. The larger the gap between X and Y, the larger the balloon payment.
Monthly Payment = Loan × r ÷ (1 − (1+r)^−n), where r = annual rate ÷ 12 ÷ 100 and n = amortization months. This is identical to a standard mortgage payment formula — the balloon feature only changes when you pay off the remaining balance, not the monthly payment amount itself.
Balloon mortgages exist for residential homes but are far less common since the 2008 financial crisis. Qualified Mortgage (QM) rules generally restrict balloon loans in residential lending. They are allowed for some rural and small-creditor mortgages. Balloon mortgages are much more common in commercial real estate. Always check current regulations with a licensed mortgage professional.
For a $300,000 loan at 6% with 30-year amortization and 5-year balloon: the balloon payment is approximately $279,163 after 60 payments. For a 7-year balloon on the same loan: approximately $269,000. The longer the balloon term, the smaller the balloon payment (more principal is paid off), but the lower monthly payments remain the same.
An interest-only balloon loan requires only interest payments each month (monthly payment = loan × monthly rate). No principal is paid down, so the entire original loan amount becomes the balloon payment at the end of the term. These are common in hard money loans, bridge loans, and some commercial structures. Monthly payments are the lowest possible, but the balloon equals the full original loan amount.
