How to Use the Australia HECS / HELP Calculator
The Australia HECS/HELP Calculator computes your compulsory HECS-HELP repayment for 2025–26 based on your repayment income. Repayments are triggered at a minimum income threshold and increase progressively as a percentage of income until the debt is fully repaid.
Enter your total repayment income (salary, business income, and other income including investment income and fringe benefits). The calculator shows your minimum repayment rate, annual compulsory repayment, and estimates how many years until your debt is repaid at your current income.
A critical nuance is indexation: your HECS-HELP debt is indexed to CPI each year on 1 June. In 2023, indexation hit 7.1%, adding thousands to many debts. Although the government has capped future indexation to the lower of CPI and wages growth, high-inflation periods can significantly increase your debt before your income triggers repayments.

Frequently Asked Questions
What is the HECS-HELP repayment threshold for 2025–26?
The minimum repayment income threshold is $54,435 for 2025–26. Below this, no repayments are required regardless of your debt. Above this, repayment rates range from 1% to 10% of your income depending on how high your income is.
Does HECS affect my take-home pay?
Yes. Your employer withholds your estimated HECS repayment from your pay if you've indicated a HECS debt on your Tax File Number Declaration. The ATO recalculates the exact amount when you lodge your tax return. If you've been withheld too much or too little, you'll get a refund or owe the difference.
Is HECS interest-free?
HECS-HELP doesn't charge interest, but is indexed to CPI on 1 June each year. Indexation increases your debt in line with inflation. In recent years: 2023 indexation was 7.1%, 2024 was 4.7%, and 2025 is expected around 2.5%. The government has committed to capping future indexation at whichever is lower: CPI or wages growth.
Should I make voluntary HECS repayments?
Voluntary repayments reduce your debt immediately, avoiding future indexation on that amount. However, there's no interest to save — just indexation. If inflation is low (below your potential investment return), investing extra money may outperform voluntary HECS repayments. This is a personal finance decision based on your circumstances.
What happens to HECS debt if I leave Australia?
Your HECS debt follows you. Since 2017, Australians living overseas with HECS debt must make repayments based on their worldwide income if their income exceeds the minimum repayment threshold. Failing to report overseas income and pay can result in compounding debt. You report via the overseas income declaration process.
