Super Caps Tool
Maximize your retirement wealth by navigating Australia's super contribution caps. Calculate your tax savings and ensure you stay within the 2024-2025 ATO limits.

"Your current strategy saves you $750 in immediate income tax this financial year. By salary sacrificing $5,000, you're effectively keeping money that would have otherwise gone to the ATO."
In the Australian superannuation system, contributions are broadly divided into two categories: Concessional and Non-Concessional. Understanding the distinction between these two is the single most important factor in optimizing your retirement strategy. **Concessional contributions** are 'before-tax' amounts, including your employer's compulsory SG payments and any salary sacrifice you arrange. These are taxed at a flat 15% within the fund, which for most Australians is significantly lower than their marginal income tax rate. This provides an immediate tax saving and allows more of your money to start compounding immediately. **Non-concessional contributions**, on the other hand, are made from 'after-tax' money—income that has already been taxed at your marginal rate. While there is no immediate tax deduction for these, they allow you to move larger sums of wealth into the low-tax environment of a super fund (where earnings are capped at 15%). In 2024-2025, balancing these two types of contributions requires careful tracking against annual caps to avoid punitive excess contribution taxes. This tool helps you visualize how much of each type you are contributing and identifies the potential tax savings generated by your concessional strategy.
The estimator uses the 2024-2025 ATO thresholds to calculate your contribution health. For **Concessional Contributions**, the general cap is $30,000 per year. The tool calculates your employer's mandatory contribution (11.5% of salary) and subtracts it from this cap to show your remaining 'Salary Sacrifice' headroom. The tax saving formula is: *(Marginal Tax Rate - 15%) * Concessional Amount*. This represents the literal 'Cash in Pocket' value of contributing to super vs taking the money as salary. For **Non-Concessional Contributions**, the annual cap is currently $120,000. The tool tracks your input against this limit and accounts for the 'Bring-Forward' rule (where you can contribute up to 3 years' worth of caps at once if your super balance is under $1.66 million). The logic emphasizes the 'Gross-to-Net' transition, ensuring users understand that non-concessional money is already 'clean' of income tax, whereas concessional money will attract a 15% entry tax within the fund. By modeling these side-by-side, the tool provides a clear 'Contribution Map' for the current financial year.
If your total super balance is under $500,000, you can 'Carry Forward' unused portions of your concessional cap from the last five years. This is a massive opportunity for those who have had career breaks or low-income years. An expert tip is to use a large concessional contribution in a year where you have a capital gain (e.g., from selling shares) to offset the high tax bill.
If your combined income and concessional contributions exceed $250,000, your concessional tax rate jumps from 15% to 30%. While this reduces the benefit, it is still usually lower than the 47% top marginal rate. However, at this level, non-concessional contributions often become more attractive for long-term wealth transfer due to the lack of entry tax.
Your ability to make non-concessional contributions is tied to your TSB as of June 30th of the previous year. If your balance exceeds $1.9 million (the Transfer Balance Cap for 2024-25), your non-concessional cap drops to zero. Always check your TSB in MyGov before making large post-tax contributions to avoid heavy penalties.
Before starting a salary sacrifice, ask your payroll for your projected employer super total for the year. Many people forget that their 11.5% SG counts towards the $30,000 concessional cap. If you earn $200,000, your employer already puts in $23,000, leaving you only $7,000 of 'tax-deductible' headroom.
Instead of a lump sum, automate a $200-$500 monthly salary sacrifice. Because this is taken out *before* tax, you might only see a $130 reduction in your take-home pay, while your super grows by the full $200. This is the most painless way to hit your caps consistently.
If your partner has a much lower super balance or is out of the workforce, you can 'split' up to 85% of your concessional contributions into their account. This helps balance your retirement wealth as a couple, which is vital for staying under the individual Transfer Balance Caps later in life.
Mark received a $20,000 performance bonus. Instead of taking it as cash (and losing ~$7,500 to tax), he directed the entire amount as a concessional contribution to his super. Because he was under his cap, the tax was only $3,000 (15%). He effectively started his investment journey with $4,500 more than if he had taken the cash.
Sarah inherited $150,000. She used the 'Non-Concessional Bring-Forward' rule to contribute $120,000 into her super in a single day. While she didn't get a tax deduction, all the dividends and growth on that $120k are now taxed at just 15% inside the fund, rather than her personal 37% rate.
James accidentally over-contributed to his concessional cap by $5,000 because he didn't factor in his employer's SG. The ATO taxed the excess $5,000 at his marginal rate (45%) plus an interest charge. He now uses this estimator every July to set his payroll sacrifice exactly to the remaining headroom.
