How Long Does It Take to Pay Off HECS Debt?

How long it takes to pay off HECS debt depends almost entirely on your salary. As of 2026, a typical $30,000 balance takes roughly 6–9 years to clear on an $80,000–$90,000 income through compulsory repayments alone, while incomes under $67,000 make no repayments at all — meaning the debt can outlast your career if your earnings stay low.

What decides how long you'll be repaying

Three variables set your payoff timeline, and only one of them is really in your control.

Your repayment income. Compulsory repayments are calculated on repayment income (taxable income plus reportable fringe benefits, reportable super contributions and a few other add-backs). Under the marginal system that applies from 2025–26, you pay nothing below $67,000, approximately 15 per cent of income between $67,000 and about $125,000, and approximately 17 per cent of the portion above that. Every pay rise shortens your timeline twice over — it increases the repayment and it outpaces indexation.

Indexation. Each 1 June the ATO indexes your outstanding balance. Since the 2023–24 reforms, the rate is the lower of CPI and the wage price index, which has kept recent indexation in the range of roughly 3–4 per cent. Indexation is the headwind your repayments must beat: if your annual repayment is smaller than the indexation added, your balance grows despite repaying.

Your starting balance. The 20 per cent HELP debt reduction legislated in 2025 cut most balances substantially, which pulled years off many timelines. Check your current balance through myGov before estimating anything — it may be lower than you think.

Annual repayments by salary (2025–26 settings)

These are approximate annual compulsory repayments under the marginal system as of 2026. Your employer withholds an estimate each pay cycle, but the true amount is settled at tax time.

The jump between $70,000 and $90,000 is the important story: an extra $20,000 of salary multiplies your repayment nearly eight-fold, because the marginal design concentrates repayments on income above the threshold.

Payoff timelines for a $30,000 debt

The table below models a $30,000 starting balance with indexation assumed at approximately 3 per cent a year and salary held constant — a deliberately conservative simplification, since most people's incomes rise. Treat these as order-of-magnitude estimates, not predictions.

The non-linearity is stark. Around the high-$70,000s your repayment only just covers indexation, so the balance barely moves. Once you clear roughly $85,000–$90,000, each extra dollar of salary attacks the principal directly and the timeline collapses quickly. This is why the average time to repay a HELP debt in Australia sits somewhere around a decade: it blends fast-repaying high earners with low earners repaying nothing.

Does the debt ever expire?

No. HELP debt has no time limit and no age limit. It does not expire after 25 years, it follows you if you move overseas (you must keep reporting worldwide income to the ATO), and repayments continue from any repayment income you earn in retirement, though most retirees fall under the threshold. The only events that end a HELP debt without repayment are death — the remaining balance is cancelled, not passed to your estate's beneficiaries — and rare cases of remitted debt. The Australian Government's Study Assist guidance on paying back your loan covers these rules in detail.

Practically, this means a low income does not create a debt problem the way an unpaid bank loan would. No interest compounds, no collector calls, and nothing is repossessed. The cost of a slow timeline is indexation and the borrowing-power drag on future loan applications — real costs, but bounded ones.

How to pay off HECS faster (and whether you should)

Voluntary repayments. You can pay any amount directly to the ATO at any time. The classic tactic is paying before 1 June so the payment lands before indexation is applied. On a $30,000 balance with 3 per cent indexation, a well-timed $5,000 voluntary payment saves about $150 of that year's indexation and every subsequent year's compounding on it.

Watch the final year. The strongest mathematical case for voluntary repayment is when your balance is small and your compulsory repayment would overshoot it. Clearing the last $1,000–$2,000 yourself stops another year of withholding and gets the over-withheld amount back into your pay sooner.

But mind the opportunity cost. HECS is interest-free and indexed at the lower of CPI and wages, so it is almost always the cheapest debt you hold. Money used for voluntary repayments typically earns more offsetting a 6 per cent mortgage, or even in a high-interest savings account when indexation runs near 3 per cent. Rushing to zero is a psychological win more often than a financial one.

Run both scenarios — compulsory-only versus compulsory-plus-voluntary — through the calculator and compare the payoff years side by side before committing spare cash.

Worked example: Priya's timeline

Priya graduates with $28,000 of HELP debt and starts on $72,000. Year one, her repayment is roughly $750 — less than indexation, so her balance creeps up slightly. By year three she is on $88,000, repaying about $3,150 a year, and the balance finally starts falling. At year five she is promoted to $105,000, repaying roughly $5,700 a year, and the remaining balance clears in about four more years. Total time: approximately nine years, with more than 80 per cent of the debt repaid in the second half. That back-loaded shape is typical — early-career years barely dent the balance, and the real repayment happens once salary growth kicks in.

Contrast Priya with her classmate Tom, who graduates with the same $28,000 but moves into a community-sector role that plateaus around $68,000. His repayment hovers near $150 a year — nowhere near 3 per cent indexation on the balance — so after nine years he owes more than he started with, despite never missing a repayment. Tom is not doing anything wrong, and nothing bad happens to him: no default, no interest, no mark on his credit file. But his example shows why "how long will it take" has no single answer. The same degree, the same debt and the same repayment rules produce a nine-year payoff for one person and an indefinite one for another, purely on the shape of the salary curve. If your projected income sits near the threshold, plan around the borrowing-power and indexation costs of a long-lived balance rather than around a payoff date that may never arrive.

What speeds timelines up — and what quietly stretches them

A few real-world factors move payoff dates more than most people expect, in both directions.

Salary growth is the great accelerator. The static-salary tables above are conservative on purpose. If your income grows even 4 per cent a year, a timeline modelled at 14 years on a flat $85,000 typically compresses to 8–10 years, because each rise pushes more income into the 15 per cent band. Graduates in fields with steep early pay curves — engineering, law, tech, medicine — routinely halve the naive estimate.

Career breaks quietly add years. Parental leave, part-time years, further study or a stint below the threshold pause repayments entirely while indexation keeps running. Two years out of the workforce mid-timeline does not add two years to the payoff date — it adds two years plus the compounding on two rounds of indexation nobody repaid.

Adding new study restarts the clock. A postgraduate course on FEE-HELP tops up the same consolidated balance the compulsory repayment works against. Your repayment does not increase — it is set by income, not balance — so a $20,000 masters simply bolts extra years onto the end of the schedule.

Fringe benefits and investment income count. Repayment income includes reportable fringe benefits, net investment losses and reportable super contributions. Salary packaging can push your repayment income above your cash salary, raising repayments and shortening the timeline — sometimes to the surprise of hospital and charity workers who package heavily.

The final-year overshoot. In your last year, employer withholding keeps running as if the debt were still large, and the excess only comes back as a refund after you lodge. Once your balance drops below one year's repayment, you can notify your employer to stop the HELP withholding component — a small admin step that returns cash to your pay months earlier.

The bottom line

Expect roughly 6 to 9 years to pay off a typical HECS debt on a solid graduate salary trajectory, far longer if your income hovers near the $67,000 threshold, and as little as 2–3 years on six figures. The debt never expires, but it also never charges interest. Check your real balance on myGov, model your own salary path, and let the numbers — not anxiety — decide whether to speed things up.
