How Superannuation Grows Over Time
Your superannuation balance at retirement depends on four main factors: your starting balance, ongoing contributions (employer SG + any salary sacrifice), investment returns, and fees. Compound growth means even small changes made early have a massive impact decades later.
Super Guarantee Rate
The super guarantee rate for 2025–26 is 12% of your ordinary time earnings. Your employer must contribute this amount into your super fund on top of your salary. This rate reached its long-planned 12% target from 1 July 2025.
Contributions Tax
Concessional contributions (employer SG and salary sacrifice) are taxed at 15% inside super, rather than your marginal tax rate. This is what makes salary sacrifice into super so tax-effective for most workers. The concessional contributions cap is $30,000 per year for 2025–26.
