Does HECS-HELP charge interest?

No. HECS-HELP does not charge interest. Instead, your debt is indexed to inflation (CPI) on 1 June each year. Since 2023, the government has capped indexation at the lower of CPI or the Wage Price Index, preventing spikes like the 7.1% indexation in 2023.

Should I voluntarily pay off HECS faster?

Generally no. Since HECS only charges inflation indexation (typically 2-4%), your money almost always earns more invested elsewhere (e.g., shares at 7-10%, or even a savings account at 4.5%). The exception might be if you have a very large debt and indexation is unusually high.

What happens to HECS if I go overseas?

Since 2017, Australians living overseas must lodge a tax return and make HECS repayments if their worldwide income exceeds the threshold. You report your overseas income to the ATO each year. Failure to lodge can result in penalties.

Does HECS affect my borrowing power for a home loan?

Yes. Lenders include your HECS repayment as a liability in their serviceability calculations. A $30,000 HECS debt might reduce your borrowing power by $30,000-$50,000 depending on the lender. However, it doesn't affect your credit score.

Got a HECS-HELP debt? You're not alone — over 3 million Australians owe a combined $78+ billion in student debt. HECS-HELP repayments are income-contingent: you only start paying when your income exceeds the minimum repayment threshold. This calculator shows you exactly how much is deducted from your pay, when your debt will be cleared, and whether making voluntary repayments makes financial sense.

Real-World Examples

Graduate Starting Career

Mia has $28,000 in HECS debt and starts a job earning $65,000/year. She expects 3% annual pay rises.

At $65,000, Mia's compulsory repayment is 2% = $1,300/year (~$50/fortnight). With 3% annual pay rises and CPI indexation of ~3%, her HECS will be paid off in approximately 12-14 years without voluntary repayments.

High Earner Fast Payoff

James earns $130,000 and has $45,000 in HECS debt remaining.

At $130,000, James pays 7.5% = $9,750/year. At this rate, his HECS is paid off in under 5 years. There's no benefit to making voluntary repayments — his money is better invested elsewhere.
