Estimate what a car loan with a balloon payment costs each week, fortnight or month, how much is left owing at the end of the term, and what the balloon does to total interest. Set the balloon to 0% to see the same loan without one. Then talk to us about a real, lender-checked figure.

The comparison table uses your amount, deposit, rate and term above and recalculates as you change them. Estimate only — not a quote or an offer of finance. Actual repayments depend on the lender’s rate, fees, charges and assessment. Interest is applied monthly; weekly and fortnightly figures are the monthly repayment converted pro rata.
What a balloon payment does to a car loan
A balloon (sometimes called a residual) is a lump sum that is deferred to the end of the loan instead of being repaid in the regular instalments. Because the instalments only have to clear the amount financed minus the balloon, they are lower. The balloon itself is still owed on the final day, and because the balance of the loan stays higher for longer, more interest is charged over the term. That is the whole trade-off: lower repayments now, more interest overall, and a lump sum to deal with at the end. The concept, and when it does and does not make sense, is explained in more depth in balloon payment car loans explained; this page is the numbers.
How to read the results
- Repayment: the regular instalment at the frequency you selected. The weekly and fortnightly figures are the monthly repayment converted pro rata, which is how most lenders quote them.
- Balloon owing at end of term: the lump sum you will need to pay out, refinance, or clear by selling or trading the car. It is the percentage you selected applied to the amount financed (loan amount less deposit).
- Total interest: interest charged over the whole term, including the interest attributable to carrying the balloon.
- Total repayments incl. balloon: every instalment plus the balloon. Compare this line, not the repayment, when deciding whether a balloon is worth it.
- Comparison table: the same loan at 0%, 20%, 30% and 40% balloons, plus whatever you selected. It recalculates when you change any input.
Choosing a balloon percentage
For an ordinary consumer car loan, the balloon is a figure you and the lender agree on. Lenders cap it, typically by term and by the car's age, because they want the car to be worth more than the balloon when the loan ends. A sensible starting point is to estimate what the car will realistically be worth at the end of the term and keep the balloon comfortably below that, so you are not left owing more than the car will fetch.
A note on ATO residual guidance. The Australian Taxation Office publishes minimum residual value guidance for certain leasing arrangements, including novated leases. That guidance applies to those tax structures; it does not set or require a balloon on an ordinary car loan, and the percentage you select in this calculator is not an ATO figure. If you are looking at a novated lease, the residual rules and end-of-term options are covered in novated lease residual value, and the structural comparison is in chattel mortgage vs novated lease.
A worked example
On the calculator's default settings (a $40,000 loan, no deposit, 8.5% p.a., five years), the loan without a balloon costs about $821 a month. With a 30% balloon it costs about $659 a month, roughly $161 a month less, but $12,000 is still owing at the end and total interest is around $2,330 higher over the five years (about $11,570 against $9,240). Move the balloon slider to see how the gap changes; the comparison table shows all four settings at once.
What happens at the end of the term
- Pay it out from savings and keep the car.
- Refinance the balloon into a new loan. Whether that is available, and at what rate, depends on the lender's assessment at the time, the car's age and your circumstances. See refinancing a car loan.
- Sell or trade the car and use the proceeds to clear the balloon. If the car is worth less than the balloon, you pay the difference.
What the calculator does not include
Establishment fees, monthly account fees, early payout costs, insurance, on-road costs and any dealer or broker charges. It applies a single interest rate for the whole term and assumes repayments are made on time. Lenders quote a comparison rate that includes certain fees; the rate you enter here is the interest rate only. It is an estimate, not a quote or an offer of finance.

Balloon payment calculator FAQs
How is a balloon payment calculated?
It is a percentage of the amount financed. On a $40,000 loan with no deposit, a 30% balloon is $12,000. The regular repayments are then calculated on the loan with that $12,000 deferred to the final day, and interest is charged on the full balance throughout.
Does a balloon reduce the interest rate?
No. It reduces the regular repayment, not the rate. Because more of the loan is outstanding for longer, total interest over the term is higher than for the same loan without a balloon.
What is the maximum balloon on a car loan?
It depends on the lender, the loan term and the age of the car. Lenders set caps so that the car is expected to be worth more than the balloon at the end of the term. A broker can tell you the maximum a specific lender will allow before you apply.
Is a balloon the same as a residual?
The words are often used interchangeably. In practice "residual" is more common with leases, where the figure may be governed by the lease rules and, for novated leases, by ATO guidance. On an ordinary car loan the balloon is simply an agreed deferred amount.
Can I pay the balloon early?
Often, but the loan contract sets the terms. Some loans allow extra repayments toward the balloon without penalty; others apply early payout costs. Check before you sign.
Is this calculator a quote?
No. It is an estimate based on the figures you enter. Your actual repayment depends on the lender's rate, fees and assessment of your application.
