Understanding Your Superannuation

Superannuation is Australia's compulsory retirement savings system. Your employer contributes a minimum of 12% (the Super Guarantee rate for 2025-26) of your ordinary time earnings into a super fund on your behalf. You can boost your retirement savings through salary sacrifice (pre-tax contributions) and after-tax contributions. This calculator helps you understand how your super will grow over time and the tax implications of different contribution strategies.

Key thresholds to be aware of: the concessional contribution cap is $30,000 per year, the non-concessional cap is $120,000 per year, and Division 293 tax applies when your income plus super contributions exceeds $250,000. If your total super balance is below $500,000, you may be able to use unused caps from the previous 5 years through the carry-forward rule.

Frequently Asked Questions

How is the Super Guarantee (SG) rate calculated?

The SG rate for 2025-26 is 12% of your ordinary time earnings. Your employer must contribute this amount to your super fund. The SG is capped at the Maximum Super Contribution Base of $62,500 per quarter ($250,000 per year).

What is Division 293 tax?

Division 293 is an additional 15% tax on concessional super contributions for high-income earners. It applies when your income plus concessional contributions exceeds $250,000. Even with Div 293, super contributions are typically taxed at a lower rate than your marginal tax rate.

What are carry-forward contributions?

If your total super balance is below $500,000, you can carry forward unused concessional contribution caps from the previous 5 financial years. This allows you to make larger concessional contributions in a single year without exceeding the cap.

How does salary sacrifice into super work?

Salary sacrifice is an arrangement where you agree with your employer to redirect part of your pre-tax salary into super. These contributions are taxed at 15% in your super fund instead of your marginal tax rate, which can provide significant tax savings.

What is the ASFA Retirement Standard?

The Association of Superannuation Funds of Australia (ASFA) publishes the Retirement Standard, which benchmarks the annual budget needed to fund a comfortable or modest standard of living in retirement. For a single person, comfortable retirement requires about $52,085 per year.
