How This Calculator Works
Enter your current super balance, total monthly contributions (employer Super Guarantee plus any salary sacrifice or personal contributions), the return you expect, and years to retirement. The calculator compounds the balance monthly and shows the projected balance and how much is investment growth.
The Formula
Future Value with Regular Contributions
P = starting amount, PMT = monthly contribution, r = monthly rate (annual ÷ 12), n = number of months
Worked Example
A $50,000 balance plus $800 a month for 20 years at 7% grows to about $618,678 — with roughly $376,678 of that being investment growth. Australian super is built on the Super Guarantee (your employer contributes a legislated percentage of your wages into super), which you can boost with salary sacrifice or personal contributions. Super is concessionally taxed — contributions and earnings are generally taxed at 15% (lower than most marginal rates), which is why it compounds efficiently over a working life. This projection is before fees, insurance premiums, and tax nuances.
Key Insight
Superannuation is the backbone of retirement saving in Australia, and a few features shape how it grows. Contributions come from the compulsory employer Super Guarantee (a set percentage of your ordinary earnings, legislated to rise over time) plus voluntary contributions — salary sacrifice (pre-tax, within the concessional cap) and after-tax personal contributions. The tax treatment is the key advantage: concessional contributions and fund earnings are generally taxed at just 15%, well below most workers' marginal rates, so money compounds faster inside super than in a normal taxable account — and in the retirement (pension) phase, earnings can become tax-free. Caveats this simple projection omits: the 15% contributions tax (so enter net-of-tax contributions, or expect the real figure to be a bit lower), the concessional contributions cap (exceeding it triggers extra tax), and fund fees and any insurance premiums deducted from your balance (these compound against you, so a low-fee fund matters a lot over decades). Practical levers: consolidate multiple super accounts to avoid paying duplicate fees, check your fund's investment option and fees, and consider salary sacrifice if it's tax-effective for you. The biggest driver of the final balance is time and consistent contributions — small differences in fees or contribution rate compound into large differences over a 20–40 year horizon, which is why engaging with your super early matters. Use this as a planning estimate, and check your fund and the ATO for the contributions caps, tax, and fees specific to your situation.

Frequently Asked Questions
How is superannuation growth calculated?
Your starting balance and each monthly contribution compound at the expected return (annual rate ÷ 12 per month). $50,000 plus $800/month for 20 years at 7% grows to about $618,678, with roughly $376,678 of that being investment growth — before fees and tax nuances.
What contributions go into super?
The compulsory employer Super Guarantee (a legislated percentage of your earnings) plus any voluntary contributions you make — salary sacrifice (pre-tax) or after-tax personal contributions. Enter your total monthly contributions; for accuracy, use the amount landing in super after the 15% contributions tax on concessional amounts.
Why is super taxed concessionally?
To encourage retirement saving. Concessional contributions and fund earnings are generally taxed at just 15% — below most workers' marginal tax rates — so money compounds faster inside super than in a normal taxable account. In the retirement pension phase, earnings can become tax-free, adding to the benefit.
What does this projection leave out?
The 15% contributions tax, the concessional contributions cap (exceeding it incurs extra tax), and fund fees and insurance premiums deducted from your balance. Fees in particular compound against you over decades, so a low-fee fund matters — check your fund and the ATO for the specifics that apply to you.
How can I grow my super faster?
Consolidate multiple accounts to avoid duplicate fees, choose a low-fee fund and an appropriate investment option, and consider salary sacrifice if it's tax-effective. The biggest levers are time and consistent contributions — engaging early, since small differences in fees and contribution rate compound hugely over a working life.
When is this calculator unreliable?
Less reliable when investment returns variable (default growth fund 7-9% long-term avg with substantial drawdowns 30%+ historical), when contribution caps changing periodically, when Division 293 tax 30% concessional for income >$250K, when Transfer Balance Cap $1.92M 2024-25 limits retirement phase, when preservation age 60+ varies birth year, when salary sacrifice vs after-tax mix differs, or when Government Co-Contribution / LISTO low-income substantial benefits not modeled.
