Useful next calculations
When to use this calculator
- Before accepting a pay change, bonus or contribution arrangement.
- When you want a simple take-home or conversion estimate before payroll or filing.
- When you need to convert between hourly, monthly and annual pay.
- When you want to compare two pay scenarios using the same assumptions.
A worked example
These are the example figures the calculator opens with.
| Input | Value |
|---|---|
| Capital Gain (A$) | A$50,000 |
| Holding Period | More than 12 months (50% CGT discount) |
| Other Taxable Income (A$) | A$0 |
| Residency | Australian Resident |
For those figures the calculator returns:
- Taxable gain (after discount): A$25,000.00
- CGT payable: A$1,020.00
- Effective CGT rate: 2.00%
- Net proceeds after tax: A$48,980.00
- Tax saved by 50% discount: A$4,500.00
How to read your results
Taxable Gain (after discount)
Review this figure alongside gross income and the local tax rules that apply to you. It is a planning estimate, not a filing result.
Net Proceeds After Tax
Review this figure alongside gross income and the local tax rules that apply to you. It is a planning estimate, not a filing result.
Tax Saved by 50% Discount

Method & assumptions
This calculator applies the 2026–27 Australian income tax brackets to determine capital gains tax liability. For Australian residents who have held an asset for more than 12 months, only 50% of the capital gain is included in assessable income — a concession introduced to reflect inflation and encourage long-term investment. The calculator determines CGT payable by finding the marginal tax on your combined income (other income plus taxable gain) and subtracting the tax attributable to other income alone, isolating the tax cost of the gain itself. Non-residents are assessed under a separate schedule with no tax-free threshold and no CGT discount.
Results are estimates only and do not constitute tax advice. Individual circumstances such as capital losses carried forward, small business CGT concessions, main residence exemptions, or prior-year losses can significantly alter the outcome. Consult a registered tax agent or the ATO website before lodging your return.
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.
- 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.
