What is HECS-HELP Repayment Calculator?
▾
Hey there! If you've ever looked at your Australian payslip and wondered why a chunk of your hard-earned money is vanishing under the label 'HELP' or 'HECS,' you are definitely not alone. HECS-HELP is the Australian government's way of letting you study now and pay later. It's an income-contingent loan, which is just a friendly way of saying you only start paying it back once you're earning a decent wage. Unlike a scary credit card or a standard bank loan, there is absolutely no commercial interest charged on this student debt. But here's the catch: it isn't completely free money. Every year on June 1st, your debt gets hit with indexation. This means the government adjusts your balance to keep up with the rising cost of living. If prices at the supermarket go up, your student debt goes up too. When your income crosses the magic line—which is $54,435 for the 2024-25 financial year—the tax office automatically starts taking a slice of your paycheck to pay it off. Why does this matter to your everyday life? Well, it directly affects how much cash actually lands in your bank account every pay cycle. If you're trying to save for a holiday, buy your first home, or just budget for weekly groceries, knowing exactly how much HECS will take out of your pay is a game-changer. Our calculator does the heavy lifting for you, so you can plan your financial life with confidence and avoid nasty surprises at tax time!

How to HECS-HELP Repayment Calculator
▾
- 1The tax office calculates your 'Repayment Income'—which is your normal salary plus extra perks like salary packaging (fringe benefits) and voluntary super contributions.
- 2If your total repayment income goes over the yearly minimum threshold ($54,435 for the 2024-25 year), you must start making repayments.
- 3The rate you pay applies to your entire income, starting at a gentle 1% and climbing up to 10% as your salary grows.
- 4Your employer usually takes this out of your regular pay automatically, as long as you ticked the 'Yes, I have a HELP debt' box on your tax declaration form.
- 5On June 1st each year, the government adjusts your remaining debt balance to match inflation so the loan keeps its real-world value.
- 6When you lodge your annual tax return, the ATO does the final math, matches what your boss withheld with what you actually owe, and updates your balance.
- 7You can check your current balance anytime by logging into your myGov account linked directly to the Australian Taxation Office (ATO).
Worked Examples
▾
Just crossed the starting line!
Meet Sarah, a retail supervisor earning $60,000. Because she is just over the $54,435 threshold, she sits in the 1% repayment bracket. The tax office will calculate her annual repayment as 1% of $60,000, which is $600. Her employer will deduct about $11.50 per week from her pay to cover this, meaning she won't face a surprise bill at tax time.
Stepping up the career ladder.
Dave is a designer making $85,000 a year. This salary puts him in the 4.5% repayment bracket. His annual compulsory repayment is $3,825 ($85,000 x 0.045). Over the course of the year, this works out to about $318.75 per month taken out of his paycheck to chip away at his $25,000 debt.
Reaching the top tax bracket.
Chloe is a project manager earning $162,000. Since she's above the top tier of $159,664, her repayment rate is 10%, which would mathematically equal $16,200. However, because her actual remaining debt is only $12,000, she will only pay the outstanding $12,000 balance plus any minor indexation, completely wiping out her debt in one go.
Why your debt grows even when you pay it.
Imagine you have a $30,000 debt. On June 1st, before your tax repayments are applied, the government indexes your debt. At a 4.7% indexation rate, your debt increases by $1,410. This means you need to make at least $1,410 in repayments over the year just to keep your balance from growing.
Real-World Applications
▾
Graduates landing their first professional job can use it to estimate their actual take-home pay and budget for rent, groceries, and savings.
Prospective homebuyers can check how much their HECS debt is lowering their monthly income to better estimate their mortgage borrowing power.
Employees considering a salary sacrifice deal (like a novated car lease) can check if the arrangement will accidentally push them into a higher HECS bracket.
Savvy savers can calculate whether making a voluntary lump-sum payment before June 1st is worth more than keeping their cash in a high-interest savings account.
Special Cases
▾
The 'Cliff Edge' Effect
For example, if you earn $62,850, your repayment rate is 1% ($628.50). But if you get a tiny $5 bonus and earn $62,855, your rate jumps to 2% on the whole amount, costing you $1,257.10! That $5 raise ended up costing you over $628 in extra repayments.
The Salary Sacrificing Trap
The ATO adds your reportable fringe benefits back to your income when calculating HECS. If you don't tell your payroll department to withhold extra tax, you might end up with an unexpected bill at tax time because your employer didn't hold back enough cash.
The June 1st Timing Gap
This means your debt is indexed on its old balance before your year's worth of hard-earned repayments are deducted. If you're planning to pay off the very last of your debt, doing it voluntarily before June 1st can save you hundreds in indexation fees.

Frequently Asked Questions
▾
What is the minimum I need to earn before I start paying back my HECS?
For the 2024-25 financial year, you don't have to pay back a single cent if your repayment income is under $54,435. Once you earn $54,435 or more, the tax office will automatically start asking for repayments. This starts at a gentle 1% of your total income and increases as your earnings grow.
Does my student debt have interest like a bank loan?
No, it doesn't charge commercial interest. Instead, it is adjusted for inflation (indexed) on June 1st every year to match the cost of living. This keeps the value of the loan in line with the economy, but it can still cause your balance to grow if inflation is high.
Can I pay off my HECS faster if I want to?
Absolutely! You can make voluntary payments through your myGov account using BPAY or credit card at any time. Just keep in mind that the old 5% bonus for voluntary payments is gone, so you're doing it purely to get rid of the debt and avoid yearly indexation.
How do I calculate my 'repayment income'?
It's not just your basic salary! The ATO calculates your repayment income by taking your taxable income and adding back things like salary packaging perks (fringe benefits), investment losses, and extra super contributions you made yourself. This total is what determines your repayment rate.
What happens to my debt if I move to another country?
You still have to pay it back! If you move overseas, you are required to report your worldwide income to the ATO. If your global earnings go over the repayment threshold, you'll need to make repayments just like you would if you were still living in Australia.
Common Mistakes to Avoid
▾
- !Forgetting to tick the 'HELP debt' box on your tax declaration when starting a new job, leading to a massive tax bill at the end of the year.
- !Thinking that salary sacrificing to reduce your taxable income will also lower your HECS repayments (it actually doesn't!).
- !Waiting for your weekly pay deductions to clear your balance before June 1st—they only get applied after you file your tax return.
- !Assuming the debt is completely interest-free and ignoring how fast inflation (indexation) can make the balance grow.
Pro Tip
If you are close to paying off your debt, try to make a voluntary repayment to clear the final balance before May 25th. This ensures the payment processes before June 1st, saving you from getting hit with indexation on a balance you're about to wipe out anyway!
Did you know?
Did you know that HECS-HELP repayments are calculated on your entire income, not just the amount above the threshold? This is different from regular Australian income tax, where you only pay higher tax rates on the portion of your income that falls into the higher brackets!
