How HECS/HELP Repayments Work in Australia

The Higher Education Contribution Scheme (HECS) and Higher Education Loan Program (HELP) provide income-contingent loans that Australian students use to defer the cost of their university education. Unlike commercial loans, HELP debts are repaid through the tax system based on your income level. The Australian Taxation Office applies a compulsory repayment percentage to your taxable income once it exceeds a minimum threshold. The repayment thresholds and rates are set by the government and adjusted annually for indexation. For the 2025-26 income year, the minimum repayment threshold is approximately $54,435, below which no compulsory repayment is required. Above this threshold, the repayment rate starts at 1% and increases progressively as income rises, reaching a maximum of 10% for the highest income earners.

One of the most important aspects of the HELP repayment system that many graduates overlook is that repayment rates are applied to the entire income above the threshold, not just the marginal amount above each bracket boundary. This means that crossing a threshold can result in a disproportionately large increase in your repayment amount. For example, if you earn $62,000 and your income increases to $63,000, pushing you into the next repayment bracket, the higher rate applies to your entire repayable income, not just the extra $1,000. This threshold effect can sometimes mean that a modest pay rise results in a noticeably larger HELP repayment, reducing the net benefit of the salary increase. Understanding this dynamic is crucial when negotiating a pay rise or considering a job change.

HELP debts are indexed annually to maintain their real value. The indexation rate is tied to the Consumer Price Index (CPI) or the Wage Price Index, whichever is lower. This means your debt balance grows each year by the indexation amount before any repayments are credited. For graduates with large HELP debts, the interaction between indexation, repayment rates, and salary growth determines how long it takes to fully repay the loan. This calculator helps you understand the specific impact of a pay rise on your HELP repayment, showing you the before and after comparison so you can plan your finances with full visibility of the change in your take-home pay.

The Threshold Effect on Pay Rises

When you receive a pay rise that pushes you into a higher HELP repayment bracket, the new rate applies to your entire repayable income, not just the amount above the new threshold. This can create a situation where a small pay increase results in a larger-than-expected increase in your HELP repayment. For instance, if you are earning just below a threshold and receive a $2,000 pay rise that moves you into the next bracket, your repayment could increase by more than $2,000 in some cases. While this does not mean you are worse off overall (the extra repayment reduces your debt faster), it does mean that the take-home benefit of the pay rise is smaller than you might expect. Being aware of these thresholds helps you understand the true value of a salary increase.
