Capital gains tax calculator

Enter what you paid, what you are selling for, and how long you held it.

How this is calculated
CGT has a lot of edge cases. Here is exactly what this calculator does and does not do.
- Discount
- 50% for individuals who held the asset more than 12 months. Companies (no discount) and super funds (33.3%) are not modelled.
- Order of operations
- Capital losses are applied to the gain first, then the 50% discount, which is the order the ATO requires.
- Cost base
- Purchase price plus the costs you enter. Brokerage, stamp duty, legal fees, and capital improvements all count. Anything you have already claimed as a deduction does not.
- Bracket creep
- The gain is taxed entirely at the rate you select. A large gain can push you into a higher bracket, so treat the result as a floor if the gain is a big share of your income.
