What is Superannuation Guarantee Calculator?
▾
Imagine future you sitting on a sunny beach, sipping a flat white, and not worrying about a single bill. That dream is fueled by your superannuation (or "super"), which is Australia’s clever way of helping you save for retirement while you work. Think of the Superannuation Guarantee (SG) as a mandatory savings plan where your boss has to chip in extra money on top of your regular paycheck. It’s not taken out of your pocket; it’s an extra bonus paid directly into your retirement nest egg. But how much should actually be landing in your account? The government sets a specific percentage of your "Ordinary Time Earnings" (your base pay, plus certain bonuses and allowances) that employers must pay. This rate is climbing steadily towards a goal of 12% by 2025. Because these contributions are taxed at a super-low rate of just 15% inside your fund—much lower than your personal income tax rate—it's one of the most tax-friendly ways to build serious wealth over time. That's where this calculator comes in. Whether you're a casual retail worker checking your payslip, a freelancer figuring out your own retirement plan, or a small business owner trying to keep your books straight, we make the math simple. By typing in your earnings, you can instantly see exactly what your employer owes you, how much tax will be taken out by your fund, and the actual amount that gets tucked away for your future. It's your ultimate tool for making sure you aren't leaving money on the table.

Formula
▾
SG Contribution = OTE × SG Rate; Concessional Tax = SG Contribution × 0.15; Net Super Added = SG Contribution − Concessional TaxVariable Legend
▾
| Symbol | Name | Unit | Description |
|---|---|---|---|
| OTE | Ordinary Time Earnings | — | Your base wage, regular bonuses, and allowances. This is the foundation used to calculate your super, and it excludes overtime. |
| SG% | Super Guarantee Rate | — | The official percentage of your OTE that your employer must pay. This rate is climbing to 11.5% for 2024-25 and hits 12% in 2025. |
| CT | Contributions Tax | — | The flat 15% tax rate that your super fund automatically deducts from all pre-tax contributions as soon as they land in your account. |
| CC Cap | Concessional Contributions Cap | — | The annual speed limit for pre-tax super contributions. Going over this limit (set at $30,000 for 2024-25) means paying extra personal income tax. |
How to Superannuation Guarantee Calculator
▾
- 1Find your Ordinary Time Earnings (OTE) for the quarter. This includes your base wage, regular commissions, and shift allowances, but leaves out overtime pay.
- 2Identify the official SG rate for the current financial year (for example, 11.5% for the 2024-25 financial year).
- 3Multiply your quarterly OTE by the SG rate to calculate the exact super dollar amount your employer is required to pay.
- 4Note the quarterly payment deadlines (October 28, January 28, April 28, and July 28) to ensure your employer pays your super on time.
- 5Account for the flat 15% contributions tax that your super fund automatically deducts from pre-tax contributions.
- 6Make sure your total pre-tax contributions (including employer SG and any personal salary sacrifice) don't exceed the annual cap.
- 7Check if you qualify for the government's LISTO refund if your annual income is $37,000 or less, which gives you back your contributions tax.
Worked Examples
▾
This contribution is well below the $30,000 concessional cap for the year.
Sarah's employer is legally required to pay $9,775 into her super fund over the course of the year. Once it lands, the fund deducts the standard 15% tax ($1,466.25). This leaves a clean $8,308.75 to be invested and grow for her future retirement.
The $700 excess will be taxed at Dave's higher personal marginal tax rate.
Dave's employer pays $20,700 in mandatory super. Dave also chooses to salary sacrifice $10,000 to boost his savings. This brings his total pre-tax contributions to $30,700, which slightly exceeds the annual $30,000 cap. He'll get a minor tax adjustment from the ATO for the $700 overage.
The LISTO scheme completely offsets the contributions tax for Chloe.
Chloe's employer pays $3,220 into her super. Usually, 15% tax ($483) would be taken out. However, because Chloe earns under $37,000, the government's LISTO scheme refunds the full $483 back into her super account, meaning her retirement savings grow entirely tax-free.
Marcus uses this to check his quarterly super statements.
Marcus wants to make sure his boss is doing the right thing. For his $8,000 in quarterly earnings, his employer must deposit exactly $920 into his super fund by the quarterly cut-off date. If the boss pays late, they face steep government penalties.
Real-World Applications

Everyday employees checking their quarterly super statements to make sure their boss is paying the correct legislated amount.
Small business owners running payroll to ensure they are calculating super obligations accurately on base wages and not overtime.
Savvy savers figuring out how much extra 'salary sacrifice' they can add without busting through their annual tax-free cap.
Freelancers and contractors calculating how much they should voluntarily chip in to keep their retirement savings on track.
People planning a big life change, like going part-time, who want to see how it affects their long-term retirement nest egg.
Special Cases
▾
Young Workers Under 18
If you are under 18 years old, there is a small catch to getting super. You must work more than 30 hours in a single calendar week to qualify for employer super contributions. Keep a close eye on your weekly rosters to see if you hit this threshold!
High Earners and the Maximum Base
If you are a high-flyer earning a very high salary, your employer's super obligation actually tops out. The government sets a quarterly limit called the Maximum Contribution Base. Any earnings above this limit (which is $65,070 per quarter for 2024-25) do not require employer super payments.
Contractors and ABN Holders
Think contractors never get super? Think again! If you hire a contractor primarily for their personal labor and skills, the ATO often treats them as an employee for super purposes. This is a massive legal trap for small business owners who forget to pay super to their regular freelancers.
Late Payment Penalties
If an employer misses the quarterly deadline by even a single day, they lose their tax deduction for those super payments. Instead, they must pay the Superannuation Guarantee Charge (SGC) to the ATO, which includes interest and admin fees, making late payments incredibly expensive.
Stapled Super Funds
To prevent you from having multiple super accounts eating away your money with fees, the government introduced 'stapled' funds. When you start a new job, your boss must pay into your existing active super fund unless you specifically tell them otherwise.

Frequently Asked Questions
▾
What on earth is LISTO and how does it help me?
Think of LISTO as a friendly high-five from the government for low-income earners. If you earn $37,000 or less, the government doesn't want your retirement savings eaten up by taxes. They will actually refund the 15% tax paid on your super contributions, up to a maximum of $500. This money goes straight back into your super account, giving your balance a neat little boost without you lifting a finger.
I earn a lot of money. Will I get hit with extra super tax?
Yes, if you are a high earner, you might run into what the ATO calls Division 293 tax. If your combined income and super contributions go over $250,000 a year, your super contributions tax rate doubles from 15% to 30%. The government does this to make sure high earners don't get an unfair tax advantage compared to everyone else. It's still generally cheaper than your top personal tax rate, but it's definitely something to budget for.
How do I actually calculate my super guarantee amount?
Calculating your super is actually quite simple once you know your Ordinary Time Earnings (OTE). You just take your OTE—which is your base pay plus regular bonuses—and multiply it by the current SG rate, like 11.5%. For example, if you earn $1,000 in a normal week, your employer needs to chip in $115 into your super fund. Just remember to leave out any overtime hours, as those don't count toward your super!
What happens if my boss pays my super late or not at all?
Employers face really strict rules when it comes to paying your super on time. If they miss the quarterly deadline, they have to pay a penalty called the Superannuation Guarantee Charge to the ATO. This charge is much more expensive than the original super payment because it includes interest and administration fees. Plus, the late payment is no longer tax-deductible for the business, which is a massive headache for them.
Can I claim a tax deduction for my employer's super payments?
Unfortunately, you can't claim a tax deduction for the super contributions your boss makes on your behalf. Since that money comes directly from your employer's pocket, they are the ones who get to claim the tax deduction. However, if you choose to make voluntary personal contributions from your own bank account, you can absolutely claim a tax deduction for those. Just make sure you submit the correct paperwork to your super fund before tax time!

Common Mistakes to Avoid
▾
- !Including overtime hours in your super calculations. Super is only paid on your Ordinary Time Earnings, so leave those extra overtime hours out.
- !Forgetting that your boss's mandatory super payments count towards your annual concessional contribution cap, which can trigger an unexpected tax bill if you salary sacrifice too much.
- !Missing the strict quarterly payment deadlines, which forces business owners to pay non-deductible penalties and interest to the ATO.
- !Assuming that anyone with an ABN is automatically exempt from super, which can lead to hefty back-payment claims from regular contractors.
Pro Tip
Log into your myGov account once a year to verify that the super payments listed on your payslips have actually landed in your super fund. It takes five minutes but ensures you don't lose out on years of compounding investment growth.
Did you know?
