Australian Loan Calculators

Consumer credit in Australia is regulated under the National Consumer Credit Protection (NCCP) Act 2009, which imposes responsible lending obligations on all credit licensees. Lenders must assess whether a loan is 'not unsuitable' for the borrower, meaning it must meet the borrower's requirements and objectives, and not create substantial hardship. While these obligations were subject to proposed reforms under the 2020 Credit Legislation Amendment Bill, responsible lending remains a key regulatory pillar.

One of the most important consumer protection measures in Australian lending is the mandatory comparison rate. Since 2003, all advertised loan rates must be accompanied by a comparison rate, an annualised figure that incorporates the interest rate plus most fees and charges, expressed as a single percentage. This allows borrowers to compare the true cost of different loans without being misled by low headline rates paired with high establishment or monthly fees. Comparison rates are typically calculated on a $150,000 loan over 25 years for mortgages and $30,000 over 5 years for personal loans.

Australian household debt-to-income ratios rank among the highest in the world at approximately 187% according to RBA data, largely driven by mortgage debt in the context of high property prices. Personal loan rates range from approximately 10–14% per annum for creditworthy borrowers, while car loan rates on new vehicles typically sit between 7–10%.
