HECS/HELP Repayment After Pay Rise Calculator Australia
See how a salary increase affects your HECS-HELP loan repayment in Australia. Enter your current salary, new salary, and HELP debt balance to calculate how the repayment rate changes, how much more you will repay annually, what your new fortnightly deduction looks like, and how many years it will take to clear your debt at the new rate. Understanding these changes helps you plan for the real take-home impact of a pay rise.
How HECS/HELP Repayments Work in Australia
The Higher Education Contribution Scheme (HECS) and Higher Education Loan Program (HELP) provide income-contingent loans that Australian students use to defer the cost of their university education. Unlike commercial loans, HELP debts are repaid through the tax system based on your income level. The Australian Taxation Office applies a compulsory repayment percentage to your taxable income once it exceeds a minimum threshold. The repayment thresholds and rates are set by the government and adjusted annually for indexation. For the 2025-26 income year, the minimum repayment threshold is approximately $54,435, below which no compulsory repayment is required. Above this threshold, the repayment rate starts at 1% and increases progressively as income rises, reaching a maximum of 10% for the highest income earners.
One of the most important aspects of the HELP repayment system that many graduates overlook is that repayment rates are applied to the entire income above the threshold, not just the marginal amount above each bracket boundary. This means that crossing a threshold can result in a disproportionately large increase in your repayment amount. For example, if you earn $62,000 and your income increases to $63,000, pushing you into the next repayment bracket, the higher rate applies to your entire repayable income, not just the extra $1,000. This threshold effect can sometimes mean that a modest pay rise results in a noticeably larger HELP repayment, reducing the net benefit of the salary increase. Understanding this dynamic is crucial when negotiating a pay rise or considering a job change.
HELP debts are indexed annually to maintain their real value. The indexation rate is tied to the Consumer Price Index (CPI) or the Wage Price Index, whichever is lower. This means your debt balance grows each year by the indexation amount before any repayments are credited. For graduates with large HELP debts, the interaction between indexation, repayment rates, and salary growth determines how long it takes to fully repay the loan. This calculator helps you understand the specific impact of a pay rise on your HELP repayment, showing you the before and after comparison so you can plan your finances with full visibility of the change in your take-home pay.
HECS/HELP Repayment Formulas
Repayment Rate: Based on HELP repayment income thresholds
Annual Repayment: Taxable Income × Repayment Rate ÷ 100
Extra per Year: New Annual Repayment − Current Annual Repayment
Fortnightly Deduction: Annual Repayment ÷ 26
Years to Repay: HELP Debt ÷ Annual Repayment
2025-26 HELP repayment thresholds (approximate):
- Below $54,435 = 0%
- $54,435 – $62,850 = 1%
- $62,851 – $66,620 = 2%
- $66,621 – $70,618 = 2.5%
- $70,619 – $74,855 = 3%
- $74,856 – $79,346 = 3.5%
- $79,347 – $84,107 = 4%
- $84,108 – $89,154 = 4.5%
- $89,155 – $94,503 = 5%
- $94,504 – $100,174 = 5.5%
- $100,175 – $106,185 = 6%
- $106,186 – $112,556 = 6.5%
- $112,557 – $119,309 = 7%
- $119,310 – $126,467 = 7.5%
- $126,468 – $134,056 = 8%
- $134,057 – $142,100 = 8.5%
- $142,101 – $150,626 = 9%
- $150,627 – $159,663 = 9.5%
- $159,664 and above = 10%
The Threshold Effect on Pay Rises
When you receive a pay rise that pushes you into a higher HELP repayment bracket, the new rate applies to your entire repayable income, not just the amount above the new threshold. This can create a situation where a small pay increase results in a larger-than-expected increase in your HELP repayment. For instance, if you are earning just below a threshold and receive a $2,000 pay rise that moves you into the next bracket, your repayment could increase by more than $2,000 in some cases. While this does not mean you are worse off overall (the extra repayment reduces your debt faster), it does mean that the take-home benefit of the pay rise is smaller than you might expect. Being aware of these thresholds helps you understand the true value of a salary increase.
Example Calculation
Salary Increase from $85,000 to $95,000, HELP Debt $30,000
- Current Rate at $85,000 = 4.5% → Annual Repayment = $3,825
- New Rate at $95,000 = 5% → Annual Repayment = $4,750
- Extra per Year = $4,750 − $3,825 = $925
- New Fortnightly Deduction = $4,750 ÷ 26 = $182.69
- Years to Repay at New Rate = $30,000 ÷ $4,750 = 6.3 years
Frequently Asked Questions
How does a pay rise affect my HECS/HELP repayment?
A pay rise can increase your HELP repayment in two ways. First, your income is higher, so even at the same repayment rate you would pay more. Second, the higher income may push you into a higher repayment bracket, increasing the percentage applied to your entire income. The repayment rate applies to your total repayable income, not just the amount above each threshold, so crossing a threshold can result in a noticeable jump in your repayment amount.
What is the minimum HELP repayment threshold for 2025-26?
The minimum HELP repayment threshold for the 2025-26 income year is approximately $54,435. If your HELP repayment income is below this amount, no compulsory repayment is required. Once your income exceeds this threshold, the compulsory repayment rate starts at 1% of your total income and increases progressively through various brackets up to a maximum of 10% for incomes above approximately $159,664.
Is my HELP repayment deducted from each pay or at tax time?
HELP repayments are typically withheld from each pay by your employer through the PAYG withholding system. When you notify your employer that you have a HELP debt (by ticking the relevant box on your TFN declaration), they increase your tax withholding to cover the expected HELP repayment. The actual repayment is then calculated when you lodge your tax return. If too much was withheld, you receive a refund; if too little, you may owe additional money.
Does HELP debt indexation affect how long it takes to repay?
Yes, HELP debts are indexed annually on 1 June based on the Consumer Price Index (CPI) or the Wage Price Index, whichever is lower. This indexation increases your debt balance, which means your repayments need to outpace indexation for your debt to decrease. In years with high inflation, indexation can add thousands of dollars to large HELP debts, potentially extending the time to full repayment. This calculator provides an estimate based on current balances without factoring in future indexation.
Can I make voluntary HELP repayments to pay off my debt faster?
Yes, you can make voluntary repayments to the ATO at any time to reduce your HELP debt faster. Voluntary repayments are in addition to the compulsory repayments deducted through the tax system. While there is no longer a discount for voluntary repayments (the 5% discount was removed in 2017), making extra payments reduces your debt balance, which in turn reduces future indexation charges and can significantly shorten the time to full repayment.
