Should I Pay Off My HECS Debt Early?
Wondering whether to pay off your HECS debt early? We break down indexation, borrowing power, and opportunity cost so you can decide.

HECS debt has a way of sitting in the back of your mind. You see the balance in myGov, feel vaguely guilty about it, and wonder whether you should just throw money at it until it disappears. We get it. But here is the thing: HECS is almost certainly the most forgiving debt you will ever have. No interest, no monthly bills, no debt collector.
So should you pay off HECS early? The honest answer is: it depends. It depends on your other debts, your goals, and what else you could do with the money. This guide walks through every angle so you can make a call that actually suits your situation. It is general information only, not advice.
🎯 The essential: HECS/HELP is the most forgiving debt most Australians have: no interest, only inflation indexation; income-contingent repayments (lose your job, pay nothing); and it dies with you. That makes it the LOWEST priority debt to clear. Pay off early mainly if you are about to apply for a home loan, your balance is tiny, or debt genuinely stresses you. Clear high-interest debt and build an emergency fund first. If you do pay, do it before 1 June.
First, how does HECS/HELP actually work?
HECS (Higher Education Contribution Scheme) is the old name; the official name today is HELP (Higher Education Loan Program). Most Australians still say HECS, and both mean the same thing day to day. The short version:
- The debt sits with the ATO. There are no monthly bills and no lender chasing you.
- No interest is charged. Instead the balance is indexed to inflation once a year (more below).
- Compulsory repayments start once your income crosses the threshold. The threshold and rates change yearly, so check the ATO for current figures.
- From 2025-26, a marginal system applies. You now repay a percentage of income above the threshold, like tax brackets, rather than a percentage of your whole income. That eased the burden for people near the threshold.
- Repayments are collected through the tax system. Your employer withholds extra via PAYG and the ATO reconciles it when you lodge.
What is HECS indexation (and why it matters)?
Instead of interest, the government adjusts your balance each year to keep pace with inflation. This is indexation, applied on 1 June to your outstanding balance. Since 2023 law changes, indexation is capped at the lower of CPI or the Wage Price Index (WPI), and that change was applied retrospectively to partially undo the large 2023 spike. Recent indexation has been around 3%.
The practical upshot: HECS is not a credit card charging 20%, or a personal loan at 10%. In most years indexation sits well below what you would earn in a high-interest savings account or pay on a mortgage. So the maths on rushing to clear it is far less compelling than for almost any other debt.
The core trade-off
HECS/HELP is unlike normal debt in three important ways:
- No interest, only indexation. The cost of carrying it is low.
- Income-contingent repayments. Lose your job or drop below the threshold, and you pay nothing. The safety net is built in.
- The debt dies with you. It is not passed to your estate, partner, or family.
These features make HECS the lowest priority debt to clear in most situations. So the real question is not “should I pay off HECS?” but what else could I do with that money? That is the opportunity cost, and it is the part that actually matters. If your mortgage rate, savings rate, or expected investment return beats the indexation rate, your money is probably working harder elsewhere.
When paying off HECS early CAN make sense
- You are about to apply for a home loan. This is the strongest practical reason. Lenders count your compulsory HECS repayments as an expense, which lowers your borrowing power. Clearing it before you apply can meaningfully lift how much a lender offers.
- You are close to the finish line. If the balance is a few thousand dollars, the peace of being fully debt-free may outweigh the small opportunity cost.
- The emotional peace factor. Some people just sleep better with no debt. If HECS causes real stress and your other priorities are sorted, that is a valid reason.
When paying off HECS early usually does NOT make sense
- You have high-interest debt. Credit cards at 20%+, personal loans, car loans: these cost far more than HECS. Clear them first, always. Our debt payoff guide helps you choose an order.
- You have no emergency fund. Keep three to six months of expenses in savings before any voluntary repayment. Without a buffer, one setback sends you borrowing at a much higher rate.
- Your offset or savings rate beats indexation. A dollar in your mortgage offset saves you your mortgage rate, which is almost certainly higher than HECS indexation. The offset wins.
- You are a long-term investor. Over long horizons, diversified returns have typically outpaced low indexation. Past returns are not guaranteed, but the maths often favours investing when indexation is low.
- You are on a low or variable income. The income-contingent safety net has real value: repayments pause automatically if your income drops.
The voluntary repayment timing trick
If you have decided to make a voluntary repayment, one timing detail is worth knowing. Indexation is applied on 1 June to your outstanding balance, so a voluntary payment made before 1 June reduces the balance that gets indexed. Even paying a few days early can save a small but real amount.
One catch: compulsory repayments withheld by your employer through PAYG are only credited to your HELP account after you lodge your tax return. So there can be a gap between what has been withheld and what the ATO has applied. Check your current balance in myGov before timing any voluntary payment.
Pay off early vs keep the debt
| Consideration | Pay off early | Keep it (invest/offset) |
|---|---|---|
| Best for | Home loan applicants, small balance, debt-averse | High-interest debt cleared, emergency fund set, long-term investors |
| Opportunity cost | Low if rates are low | Money can work harder when indexation is low |
| Emotional benefit | High for the debt-averse | Lower, but financially rational |
| Flexibility | Money is gone once paid | You keep liquidity |
Not sure where to start? Work through this in order:
- Clear high-interest debt first. It costs far more than HECS indexation.
- Build an emergency fund of three to six months of expenses.
- Buying a home soon? Paying down HECS can lift your borrowing power before you apply.
- Small balance? Paying it off may be worth the peace of mind.
- Otherwise, compare the rates. Put indexation next to your mortgage, savings, or expected investment return, and send the money where it works hardest.
- Check the ATO for current thresholds and indexation rates before deciding.

❓ Frequently asked questions
Does HECS/HELP debt have interest?
+
No. HECS/HELP debt does not charge interest. Instead, the balance is indexed each year on 1 June to keep pace with inflation, capped at the lower of CPI or WPI since the 2023 law changes. This makes it very different from a credit card or personal loan, where interest compounds and grows quickly.
Does HECS affect my home loan borrowing power?
+
Yes. Lenders factor your compulsory HECS repayments into their serviceability assessment as a regular expense. That reduces the income they consider available for mortgage repayments, which lowers your borrowing power. Paying down or clearing your HECS balance before applying for a home loan can meaningfully increase how much a lender will offer you.
What happens to my HECS debt if I die?
+
HECS/HELP debt dies with you. It is not passed on to your estate, your partner, or your family. This is one of the features that makes it fundamentally different from almost every other form of debt, and it is worth factoring into your thinking when you weigh up whether to pay it off early.
When is the best time to make a voluntary HECS repayment?
+
Before 1 June each year. Indexation is applied to your outstanding balance on 1 June, so making a voluntary payment before that date reduces the amount that gets indexed. Even a payment a few days before 1 June can save you money. Check your current balance via myGov before timing any payment.
Should I pay off HECS or invest instead?
+
It depends on the numbers and your goals. If the HECS indexation rate is lower than your mortgage interest rate, savings rate, or expected investment return, your money may work harder elsewhere. But if you are about to buy a home, or your balance is small, paying it off can make real sense. There is no universal right answer. Run the comparison with your actual numbers.
What changed with HECS repayments in 2025-26?
+
From 2025-26, Australia moved to a marginal repayment system for HECS/HELP. Under the old system, once your income crossed the threshold, you repaid a percentage of your entire income. Under the new system, you only repay a percentage of income above the threshold, similar to how income tax brackets work. This reduced the repayment burden for people near the threshold. Check the ATO website for current thresholds and rates.
