Talk to an accountant →General information only, current for the 2025-26 financial year. This estimate uses the new marginal HELP repayment system and applies your repayment to your stated balance only. It ignores changes to your income across the year, future indexation rate movements, the Medicare levy and any other study or training loan rules, and is not personal tax advice.

A Few Things This Calculator Assumes
How is my repayment worked out for 2025-26?
From 1 July 2025 the system changed. Instead of one rate applied to your whole income, the first $67,000 of repayment income is repayment-free. You then repay 15% of the part of your income between $67,001 and $125,000, plus 17% of anything above $125,000. So someone on $80,000 repays 15% of $13,000, which is $1,950, not 15% of the full $80,000.
What is "repayment income"?
It is more than just your salary. The ATO adds your taxable income, total net investment losses, reportable fringe benefits, reportable super contributions and any exempt foreign income. For a quick estimate your gross salary is usually close, but if you salary sacrifice or have an investment property, your repayment income can be higher than you expect.
What about indexation?
HELP debts do not charge interest, but the balance is indexed on 1 June each year to keep pace with inflation. Indexation was 3.2% in 2025. Because indexation now applies after compulsory repayments are credited, paying a voluntary lump sum before 1 June can reduce the amount that gets indexed. Our timeline uses an indicative 3.2% so you can see the effect.
Is a voluntary repayment worth it?
It depends on your indexation rate versus what that money could earn elsewhere, and your cash flow. There is no longer a bonus for paying early, so it is purely a numbers and certainty call. This is exactly the kind of trade-off we run through with clients before each 1 June.
