Car Finance Calculator
Work out your monthly car repayment, with or without a balloon payment.
Everything is worked out on your device. Nothing you type is sent or stored.
How it works
The calculator subtracts your deposit from the price, then works out the instalment that pays off the loan over the term, leaving the balloon to be paid at the end. Interest is charged monthly on the balance.
A balloon makes the monthly payment smaller, but the balance stays higher for longer, so you pay more interest in total. Compare the two totals before choosing one.

Questions
What is a balloon payment?
A lump sum, set as a percentage of the car’s price, that you pay at the end of the loan. It lowers your monthly instalment, but you pay more interest overall and still owe the balloon when the term ends.
What interest rate will I get?
Vehicle finance is usually priced relative to prime, which is 10.75% as of 23 September 2026. Your rate depends on your credit record, deposit and the car, so use the rate in your quote.
Does this include insurance and fees?
No. Lenders add a monthly service fee and initiation fee, and comprehensive insurance is required on financed cars. Add these to get your real monthly cost.
Is this financial advice?
No. It’s an estimate to help you compare options. Your lender’s quote is the figure to rely on.
