Money basics (Australian)

The vocabulary: APR, APY, AER, interest, inflation and the rest.

Australia does not use APR as its main disclosure. Lenders quote an interest rate alongside a comparison rate, which folds in most fees — but is calculated on a standardised example loan rather than on the amount you are borrowing. Knowing the difference between the two figures is what stops a low headline rate from misleading you.

What this section covers

  • What each advertised percentage actually includes
  • Where a headline rate misleads
  • How compounding changes a return
  • Working out the cost of a specific deal

Written for Australia. Terminology, protection limits and regulators differ between markets, so a guide from another country will not transfer cleanly.

    Answer

    What Is a Comparison Rate?

    Australian lenders must publish a comparison rate alongside the interest rate. It folds in fees — but it is calculated on a standard example, not on your loan.
