FAQ

How is my compulsory HECS-HELP repayment calculated?

Since the 2025–26 income year, HELP repayments are calculated on a marginal basis: nothing is owed below the minimum threshold, then set rates apply only to the portion of your income above it, with a cap so your total repayment never exceeds 10% of your income. This replaced the older system, which applied a single rate to your entire income once a threshold was crossed. This calculator uses recent indicative thresholds, so always check ato.gov.au for the current year's figures.

What is indexation, and why does my debt grow?

HECS-HELP debt is indexed each year, generally in line with either inflation or wage growth (whichever is lower, under rules introduced in 2023). This means your remaining balance can increase even while you're making repayments, especially early on when your debt is large.

Does making voluntary repayments help?

Yes. Voluntary repayments reduce your debt directly, which means less of it is exposed to indexation the following year. This calculator lets you add a voluntary amount per year to see the effect on your payoff timeline.
