When Will My HELP/HECS Debt Be Fully Repaid?
HELP debt does not have a fixed term like a mortgage — it grows each year through indexation and shrinks through compulsory income-based repayments. Enter your balance and income below to see a year-by-year projection of when yours will reach zero.
How Repayment Works Over Time
Each financial year, two things happen to your HELP balance. First, it is indexed on 1 June by the lower of CPI or wage price index, increasing the balance proportionally. Second, a compulsory repayment is calculated as a percentage of your taxable income — once your income exceeds the minimum repayment threshold — and collected by the ATO, either through payroll withholding or when you lodge your tax return.
Your balance will reduce each year only if your compulsory repayment exceeds the indexation added. For lower incomes, particularly those close to the threshold, indexation can chew through a meaningful portion of any repayment the ATO collects, extending the timeline substantially.
- Indexation date: 1 June each year — your balance grows before your repayment lands.
- Repayment rate: A percentage of your total taxable income, increasing progressively as income rises.
- Minimum threshold (2025–26): $54,435 — below this, no compulsory repayments are required.
- Wage growth: If your income rises each year, your repayment rate can increase, shortening the timeline.
What Affects How Long It Takes
Starting Balance
A larger balance takes longer to clear, and means more indexation is applied in dollar terms each year. Someone with $60,000 in HELP debt does not simply take twice as long as someone with $30,000 — the indexation compounds on a larger number, making early income-earning years particularly important.
Income Level and Growth
Repayment rates range from 1% to 10% of taxable income depending on earnings. At $70,000 income you are repaying around 2.5% ($1,750/year). At $120,000 you are repaying 7% ($8,400/year). A career-stage income increase can meaningfully accelerate payoff.
Indexation Rate
The HELP indexation rate has varied from as low as 0.6% (2021) to as high as 4.0% (2024). For the five years from 2021 to 2025, the average was approximately 3.0%. If indexation stays below your annual repayment amount, your balance trends downward each year. If they are close to equal, progress can feel imperceptibly slow.
Mint's Fresh Take
A lot of people assume HELP debt will just "take care of itself" over time. For low-to-mid incomes it often does not — if indexation is around 3–4% and your repayment rate is 1–2%, you are barely treading water. Running this calculation before making financial plans (like buying a property) is genuinely worthwhile.

Repayment Timeline Projection
Understanding Why Payoff Can Take Longer Than Expected
Many people are surprised when they run this calculator. A $30,000 HELP balance at $75,000 income can take 7–10 years to clear because early in the timeline, each year's repayment (around 3–4% of income) only modestly exceeds indexation of 3%. Later in the sequence, as income grows and the balance shrinks, momentum picks up and the final years clear quickly.
Three scenarios that extend payoff time:
- Income close to the threshold: Just above $54,435, only 1% of income ($545/year) is collected — far below a typical 3% indexation rate on a typical balance.
- Career breaks or part-time work: Years of no compulsory repayment still attract indexation.
- High indexation years: The 2024 rate of 4.0% added $1,200 to a $30,000 balance in one year, effectively wiping out one full year of repayments for someone on a median income.
What About Voluntary Repayments?
The ATO allows voluntary lump-sum or regular voluntary payments directly to your HELP balance at any time. These reduce the indexed principal immediately and can meaningfully shorten the timeline if made before 1 June when indexation is applied. However, unlike high-interest debt, voluntary HELP payments need to be weighed against what else you could do with that cash — see our companion article on whether early payoff actually makes sense for you.
Historical HELP Indexation Rates
The table below shows recent official HELP indexation rates. Since November 2024 legislation, the rate is capped at the lower of CPI or the Wage Price Index, which is why the 2025 rate (3.2%) is lower than it would otherwise have been.
| Year | Indexation Rate | Notes |
|---|---|---|
| 2020 | 1.8% | Pre-reform rate |
| 2021 | 0.6% | Pandemic low |
| 2022 | 3.9% | Inflation rise |
| 2023 | 3.2% | Revised down from 7.1% |
| 2024 | 4.0% | Revised down from 4.7% |
| 2025 | 3.2% | Lower of CPI or WPI applies |
Five-year average (2021–2025): 3.0% — used as the default assumption in the calculator above.
Mint Takeaway
- HELP debt does not have a fixed repayment date — it depends entirely on your income and indexation each year.
- For lower incomes, indexation can outpace compulsory repayments for several years.
- Income growth has the biggest impact on timeline — climbing into a higher repayment band cuts years off the projection.
- Voluntary prepayments before 1 June can reduce the amount indexed, particularly when you are near the end of repayment.
- The 5-year average HELP indexation rate (2021–2025) was approximately 3.0% — a reasonable planning assumption, but actual rates vary.
