Loan that uses smaller scheduled payments during the term and leaves a large remaining balance due at maturity.
A balloon loan is a loan whose regular payments do not fully repay the balance by maturity, leaving a large final amount due as a Balloon Payment.
Balloon loans matter because they can lower near-term debt service while increasing back-end refinancing risk. That tradeoff can be useful when a borrower expects an asset sale, project completion, or refinancing window before maturity.
Balloon loans are often priced with payments based on a longer amortization period than the actual contractual maturity.
That gap is what leaves a remaining principal balance due at maturity.
| Feature | Balloon loan | Fully amortizing loan | Bullet loan |
| — | — | — | — |
| Principal during the term | Partially repaid | Fully repaid by maturity | Often mostly deferred |
| Final maturity obligation | Large remaining balance | No special final balance | Most or all principal |
| Refinance dependence | Often material | Usually lower | Often high |
A borrower finances equipment with a seven-year legal maturity but monthly payments calculated on a fifteen-year amortization schedule. The monthly payment stays lower than under a true seven-year amortizing structure, but a sizable unpaid balance remains at year seven.
That unpaid balance is what makes the loan a balloon loan.
A Bullet Loan usually leaves nearly all principal until maturity. A balloon loan often repays some principal along the way before the final payment comes due.
An Interest-Only Loan defers principal during the interest-only period. A balloon loan is defined by the unpaid balance left at maturity, not by whether periodic payments cover only interest.
Balloon Payment: The maturity payment that defines the structure.
Bullet Loan: A more extreme maturity-focused repayment design.
Interest-Only Loan: Can produce a balloon-style end balance if principal is still outstanding.
Amortizing Loan: A loan that steadily reduces principal instead of leaving a large end balance.
Balloon Mortgage: The mortgage-specific version of the same loan design.
