How this calculator works
Estimate a taxable capital gain after costs, losses and the eligible 50% individual discount. Inputs are validated, passed to the versioned Australia engine, and recalculated immediately whenever a field changes.
Formula
Net gain = proceeds − cost base − selling costs − capital losses; eligible discount applies after losses.
Worked example
A qualifying resident asset held at least 12 months may receive a 50% discount.
Edge cases and assumptions
Tax residency, eligibility dates, exemptions, family circumstances and documentation can change the result. The result card calls out material assumptions and unknown components are not silently changed to zero.
