Useful next calculations
When to use this calculator
- Before buying, renting, refinancing, or reviewing a property investment.
- When you want to compare cash flow, yield, growth, and ownership costs side by side.
- When you need a fast estimate before speaking to an agent, lender, or adviser.
- When you are assessing whether a rental property still makes financial sense after a mortgage rate change.
- When you want to compare the total cost of renting against owning over a five- or ten-year horizon.
A realistic Australia planning example
Use these sample inputs as a quick scenario test, then change one variable at a time to compare outcomes.
Annual Gross Salary (A$)
A$80,000
Annual Voluntary Super Contributions (A$)
A$250 per month
Years of Saving
1 year
Marginal Tax Rate
19% ($18,201–$45,000)
After entering these figures, review total contributions, estimated release amount and tax saving vs regular savings together rather than in isolation — each metric tells a different part of the story. Then rerun the tool with one input adjusted to see which variable has the biggest effect on all three outputs before you settle on a plan.
How to read your results
Total Contributions
This is the headline outcome of the calculation, but it is most useful when read alongside the supporting metrics below it rather than in isolation. Try changing one input at a time and watching how this total moves to understand which driver has the biggest impact.
Estimated Release Amount
Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.
Tax Saving vs Regular Savings
Review this figure alongside gross income and the local tax rules that apply to you. It is a planning estimate, not a filing result or a recommendation to make a tax decision.
Extra vs Saving Outside Super
Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.
Contributions Tax Paid
Review this figure alongside gross income and the local tax rules that apply to you. It is a planning estimate, not a filing result or a recommendation to make a tax decision.
Method & assumptionsAuthoritative sources
This calculator estimates your potential benefit under the Australian First Home Super Saver (FHSS) Scheme for the 2024/25 financial year. It applies the ATO's 15% contributions tax to your voluntary contributions, caps annual eligible amounts at $15,000 and lifetime amounts at $50,000, and then estimates associated earnings at the ATO's approximate deemed rate of 4% per annum. The tax saving is calculated by comparing what you would have paid at your marginal rate versus the 15% super contributions tax.
Key caveats: the calculator uses a simplified 4% deemed earnings rate — the ATO uses the shortfall interest charge rate, which changes each quarter. Actual release amounts may differ slightly. A 30% withholding tax applies on release but a 30% tax offset cancels it out, so your effective tax on release is based on your marginal rate less the offset. Always verify your eligibility and release amount through myGov or a registered tax agent before making purchasing decisions.
Common mistakes
- !Using an assumption that is not supported by a current local quote, bill, statement or official source.
- !Treating a generic estimate as a lender, provider, payroll or tax authority decision.
- !Mixing monthly and annual inputs without converting them consistently.
- !Forgetting location-specific taxes, fees, eligibility rules or payroll deductions where they apply.
- !Testing only one scenario instead of checking how a cautious assumption changes the result.
What to do next
- Run a second scenario with a cautious assumption so you can see the downside clearly.
- Compare the result with the related calculators below before making a decision.
- Check current local rules, eligibility and provider terms before applying or committing money.
- Keep a record of the assumptions so you can update the estimate when a quote, bill or pay figure changes.
- Use the result to prepare better questions for a lender, provider, adviser or employer rather than treating it as a final answer.
