Is super calculated on gross or net pay?
In Australia, super is generally calculated from ordinary time earnings, which is much closer to gross pay before tax than net take-home pay. Use this premium calculator to estimate super based on your pay, tax assumptions, overtime exclusions, and the current super guarantee rate.

Expert guide: is super calculated on gross or net pay?
If you are trying to work out how much superannuation should be paid into your retirement fund, one of the most common questions is whether super is calculated on gross pay or net pay. The short answer for most Australian employees is this: super is generally calculated on ordinary time earnings, which is much closer to gross pay before tax than net pay after tax. In practical terms, employers do not normally look at your take-home amount when calculating compulsory super. They look at the earnings that count as ordinary time earnings, then apply the super guarantee rate.
This distinction matters because gross and net pay can be very different. Gross pay is the amount you earn before tax and other deductions are taken out. Net pay is what lands in your bank account after income tax, Medicare levy adjustments, salary sacrifice, and other deductions. If an employee incorrectly assumes super is based on net pay, they may underestimate what should be contributed. On the other hand, if they assume every dollar of gross pay counts, they may overestimate super where overtime or some payments are excluded.
The simple rule
For most employees, super is not calculated on net pay. It is usually calculated on earnings before tax, but not always on every single part of gross pay. The legal concept used by the Australian Taxation Office is ordinary time earnings, often shortened to OTE. OTE usually includes salary and wages for ordinary hours of work, commissions, shift loadings, paid leave, and many allowances. Overtime payments can be excluded if they genuinely relate to overtime hours.
What is the difference between gross pay, net pay, and ordinary time earnings?
To answer the question properly, it helps to define the three terms clearly.
- Gross pay: your earnings before tax and deductions are withheld.
- Net pay: the amount left after tax and deductions, sometimes called take-home pay.
- Ordinary time earnings: the earnings base generally used to calculate compulsory employer super contributions.
Ordinary time earnings often overlap with gross pay, but they are not identical in every case. For example, if your gross pay includes a block of overtime, your employer may not owe super on that overtime component. This is why payroll teams, accountants, and HR managers talk about OTE rather than gross pay or net pay alone.
Why net pay is the wrong base for super
Net pay is affected by tax rates, HELP or HECS repayments, salary packaging, and other personal deductions. None of those factors should usually determine the minimum compulsory super your employer pays. If super were based on net pay, two workers on the same salary but with different tax profiles could receive different compulsory super amounts, which is not how the system is designed to work. Super is intended to be tied to eligible earnings, not to after-tax cash flow.
How super is usually calculated
The standard method is straightforward:
- Identify the employee’s ordinary time earnings for the pay period.
- Apply the relevant super guarantee percentage.
- Pay that amount into the employee’s nominated super fund by the required due date.
For the 2024-25 financial year, the super guarantee rate is 11.5%. From 1 July 2025, it is scheduled to be 12%. If an employee has $2,000 in ordinary time earnings for a fortnight, an 11.5% super contribution would be $230. If the same employee takes home only $1,520 after tax and deductions, the super calculation is still based on the eligible pre-tax earnings, not the $1,520 banked amount.
| Financial period | Super guarantee rate | Example OTE | Example super amount |
|---|---|---|---|
| 1 Jul 2023 to 30 Jun 2024 | 11.0% | $2,000 | $220 |
| 1 Jul 2024 to 30 Jun 2025 | 11.5% | $2,000 | $230 |
| From 1 Jul 2025 | 12.0% | $2,000 | $240 |
Payments that are often included in ordinary time earnings
Many workers are surprised to learn that OTE can include more than just base salary. Common inclusions can be:
- Ordinary hourly wages or salary
- Annual leave, sick leave, and public holiday pay
- Shift loading related to ordinary hours
- Commissions
- Bonuses that relate to ordinary hours or performance
- Some allowances, depending on their nature
This is why reading a payslip can be tricky. A payslip may show a single gross figure, but payroll software may classify components differently for super purposes. If you are checking your employer’s calculations, ask for a breakdown of which earnings components were treated as OTE.
Payments that may be excluded from super calculations
Not every payment that appears in gross wages is necessarily included in compulsory super calculations. One of the most discussed exclusions is overtime. If a payment is genuinely for overtime hours, it is often excluded from ordinary time earnings. Some reimbursements and certain one-off non-OTE items may also be treated differently.
That means this statement is usually the most accurate one:
Real statistics and limits you should know
Super calculations do not happen in a vacuum. The contribution environment changes over time, and contribution caps matter for tax outcomes. Two numbers that regularly affect planning are the super guarantee rate and the concessional contributions cap.
| Statistic | Current figure | Why it matters |
|---|---|---|
| Super guarantee rate for 2024-25 | 11.5% | Minimum employer contribution rate on eligible earnings |
| Scheduled rate from 1 Jul 2025 | 12.0% | Raises minimum employer contribution amounts |
| Concessional contributions cap | $30,000 per year | Relevant if employer super plus salary sacrifice approaches tax-advantaged limits |
| Super guarantee quarterly due dates | 4 times per year | Helps employees monitor whether contributions are arriving on time |
Examples that make the gross versus net question easier
Example 1: Salaried employee with no overtime
Priya earns $6,500 gross per month. After PAYG withholding, her net pay is $4,965. If her entire salary is ordinary time earnings, her employer calculates super on the $6,500 figure, not on $4,965. At 11.5%, the monthly super contribution would be $747.50.
Example 2: Worker with overtime
Marcus earns $2,400 gross for the fortnight, but $300 of that amount is clearly identified as overtime. If the overtime is excluded from OTE, his super is calculated on $2,100 rather than the full $2,400. At 11.5%, his super would be $241.50. It is still not based on his net take-home pay.
Example 3: Employee only knows net pay
Sophia knows she received $1,800 in net weekly pay but is unsure of her gross. To estimate super, she first needs to estimate pre-tax pay. If her effective tax rate is about 25%, a rough gross estimate would be $2,400. If all of that is OTE, estimated super at 11.5% would be $276 for the week. This is why calculators like the one above ask whether the amount entered is gross or net.
Common mistakes people make
- Assuming super is calculated on net pay after tax
- Assuming all gross pay automatically attracts super
- Ignoring overtime exclusions
- Not checking whether bonuses, commissions, or leave payments were included
- Confusing salary sacrifice with compulsory employer super
- Reviewing bank deposits instead of payslip classifications
What employees should check on their payslip and super account
If you want to verify whether your super has been calculated correctly, start with the source documents. Compare your payslip categories to the contribution posted to your super fund. Remember that payments may not appear in the fund immediately because employers have quarterly due dates, although many pay more frequently through payroll software.
- Check your gross earnings for the pay period.
- Identify any overtime or non-OTE amounts.
- Confirm the super guarantee rate in effect for that period.
- Calculate the expected contribution on OTE.
- Compare that estimate with what your super fund receives.
What employers and payroll teams need to remember
For employers, the question is not simply gross or net. The compliance question is whether the correct earnings base has been used under superannuation law and ATO guidance. Using net pay as a base would generally be incorrect. Using total gross without checking overtime or excluded categories can also create errors. Payroll processes should clearly distinguish ordinary earnings from excluded earnings and should update contribution rates as the legislated super guarantee increases.

Final answer
So, is super calculated on gross or net pay? In almost all everyday discussions, the best answer is gross-type earnings before tax, not net pay. The more legally precise answer is that compulsory super is generally calculated on ordinary time earnings. That means the right figure is usually close to gross pay, but it may exclude overtime and certain other payments. If you are checking a payslip or planning your retirement contributions, use ordinary time earnings as your benchmark, not your take-home pay.
