Balloon payment

A balloon payment is a single large lump sum due at the end of a loan term, on top of the regular instalments paid throughout the loan. The structure reduces the size of regular repayments by deferring a substantial portion of the principal to the final payment.

How balloon loans work

In a standard amortising loan, every repayment chips away at the principal until the balance reaches zero. In a balloon loan, the regular repayments only partially amortise the principal — the remaining balance falls due as a single payment at the end.

Example

A $40,000 car loan over five years at 7% interest:

• Standard amortising loan: ~$792 per month, no balloon
• Loan with $15,000 balloon: ~$510 per month, plus a $15,000 lump sum due at month 60

The borrower pays $282 less each month in exchange for the obligation to find $15,000 at the end.

Common uses

• Vehicle finance — balloon often set close to projected residual value to align with eventual resale
• Commercial property loans — balloons allow lower regular payments while assuming refinance or sale at term end
• Equipment finance — balloon matched to expected disposal value of the asset

Risks and considerations

• Refinance risk — at term end the borrower may need to refinance the balloon if cash is unavailable
• Negative equity risk — if the asset is worth less than the balloon, the borrower owes more than the asset is worth
• Total interest — paying down less principal during the term means more interest is charged overall
• Discipline required — borrowers must plan for the lump sum from the start, not be surprised by it at term end

Always model the full payment schedule, including the balloon, before accepting a loan with this structure.
