Common questions

How is HELP debt indexed?
HELP debt is indexed to CPI on 1 June each year. This means your debt grows with inflation. Voluntary repayments made before 1 June reduce the balance that gets indexed.
When do I have to start repaying HELP?
Compulsory repayments begin when your repayment income exceeds the minimum threshold (currently $54,435 for 2025-26). The repayment rate starts at 1% and rises to 10% at higher incomes.
Should I pay off HELP or invest?
HELP is the cheapest debt you'll ever have — it only grows with CPI, not interest. If you can earn more than CPI plus a margin investing, investing may win. But paying off HELP gives certainty and improved cash flow.
