How Superannuation Works

Superannuation (or "super") is Australia's compulsory retirement savings system. Your employer is legally required to pay a percentage of your ordinary earnings into a super fund on your behalf. As of 2026, the Super Guarantee (SG) rate is 12% of your ordinary time earnings.

This money is invested by the super fund and grows over your working life. You generally cannot access your super until you reach your preservation age (currently between 55 and 60, depending on your date of birth) and retire. The system ensures that all working Australians build a nest egg for retirement.

Grows via compound returns

The Power of Compound Growth

Compound growth means you earn returns not just on your original contributions, but also on the returns that have already accumulated. Over decades, this creates an exponential growth effect often called the "snowball effect."

Starting early makes an enormous difference. Even small contributions in your teens and twenties can grow substantially by retirement age because they have more time to compound. Someone who starts saving at 18 will have significantly more at retirement than someone who starts at 30, even if the late starter contributes more each year.

Super Balance Growth (7% average annual return)

Age 25 (start at 18)$45,000

Age 35$135,000

Age 45$310,000

Age 60 (retirement)$600,000+

Choosing a Super Fund

You generally have the right to choose which super fund your employer pays into. Key factors to consider include fees, investment performance, insurance options, and the fund's investment options (e.g., growth, balanced, conservative).

Fees might seem small (e.g., 0.5% vs 1.5% per year), but over a 40-year career the difference can amount to tens of thousands of dollars. Always compare the total fees and long-term performance before choosing or switching funds.

Types of Investment Options

Growth: Higher risk, higher potential returns (mostly shares). Suits younger members.
Balanced: A mix of shares, property, and bonds. Moderate risk and return.
Conservative: Lower risk, lower returns (mostly bonds and cash). Suits those nearing retirement.
Ethical/Sustainable: Invests in companies meeting environmental, social, and governance (ESG) criteria.

Worked Examples

1

Calculating employer super contributions

Liam earns $55,000 per year. How much super does his employer contribute annually at the 12% SG rate?

Step 1: Identify the SG rate: 12%

Step 2: Calculate: $55,000 x 0.12 = $6,600

Answer: Liam's employer contributes $6,600 per year to his super fund.

Impact of starting early

Person A starts contributing $5,000/year to super at age 20. Person B starts contributing $5,000/year at age 30. At a 7% annual return, compare their balances at age 60.

Person A (40 years): $5,000/year at 7% for 40 years = approximately $998,000

Person B (30 years): $5,000/year at 7% for 30 years = approximately $472,000

Answer: Person A has over $500,000 more, despite only contributing an extra $50,000 ($5,000 x 10 extra years). The difference is due to compound growth.

3

Comparing fund fees

Fund A charges 0.5% annual fees and Fund B charges 1.5% annual fees. On a $100,000 balance earning 7% gross return, what is the net balance after 20 years for each?

Fund A (6.5% net): $100,000 at 6.5% for 20 years = approximately $352,000

Fund B (5.5% net): $100,000 at 5.5% for 20 years = approximately $292,000

Answer: The 1% fee difference costs approximately $60,000 over 20 years. Fees matter significantly over time.
