The highlighted bar marks your actual exit price. Crypto is famously volatile: these scenarios show how much swings change your outcome.
Recovering principal isn't profit: the coloured slice is what you actually made after CGT.
This calculator works out the return on a crypto purchase from what you paid and what you sold for, and the capital gains tax at your marginal rate - with the 50% discount when you've held it over 12 months. The ATO treats crypto as a capital gains tax asset, so each sale or swap can create a gain or loss.
$5,000 of Bitcoin bought at $70,000 a coin and sold 6 months later at $91,600, on a 30% marginal tax rate.
The sale brings $6,543, a $1,543 gain (30.9%). Held under 12 months, there's no CGT discount, so tax at 30% is about $463 and $1,080 is left - 21.6% after tax.
The same purchase and sale price, but held for 18 months.
Held over 12 months, the 50% CGT discount halves the taxable gain, so tax is about $231 and $1,311 is left - 26.2% after tax.
