Key Information

  • Australian car loan rates typically range from 6-12% in 2026
  • Shorter loan terms mean higher payments but less total interest
  • A 20% deposit can help secure better rates
  • Balloon payments reduce regular payments but require a lump sum at the end

Pro Tips

  • Get pre-approved before visiting dealerships for stronger negotiating position
  • Compare secured vs unsecured car loans - secured often has lower rates
  • Factor in on-road costs (registration, stamp duty, insurance) beyond the price
  • Consider fortnightly payments to pay off faster without noticing

Avoid These Mistakes

  • Focusing only on monthly payment without considering total loan cost
  • Not factoring in running costs (fuel, insurance, servicing)
  • Accepting dealer finance without comparing bank/credit union rates
  • Choosing the longest term to minimize payments (costs much more overall)
