What are the repayments on a $30,000 car loan?

Australian secured car loan rates are typically 5-9% for new cars with good credit and 7-12% for used cars. Unsecured personal loans used for cars run 7-18%. A $30,000 loan at 7% over 5 years costs about $594/month (~$5,614 total interest). Shortening to 3 years raises the repayment to ~$926/month but cuts interest to ~$3,338. Fortnightly repayments (half monthly, 26 times/year) save a small amount over the life of the loan. Source: ASIC MoneySmart; RBA Retail Deposit and Lending rates.

Worked example. $40,000 car, $5,000 trade-in, $35,000 financed at 8% over 5 years: repayment ~$710/month total interest ~$7,570. Add a 30% balloon ($12,000 due at end of term): regular repayments drop to ~$563/month but you still owe the $12,000 balloon, so total interest over the whole loan rises to ~$9,780 — the balloon trades lower repayments for higher total cost.
