Know the tax before you sell, not after
A what-if calculator for Australian CGT (Capital Gains Tax) with a per-parcel FIFO (First In, First Out) breakdown, the 50% discount threshold marked, and a sell-today versus wait comparison.
The problem
You are considering a sale. Some parcels have passed twelve months and some have not, the discount only applies to some of the gain, and the actual tax depends on your marginal rate. Working that out by hand is where most people give up and just sell.
How it works
- 1
Pick the share and the quantity
Choose a holding, enter how many shares you want to sell and at what price.
- 2
Read the parcel breakdown
Each parcel is shown separately and colour-coded — which ones qualify for the 50% discount, and which are approaching the twelve-month threshold.
- 3
Compare selling now against waiting
See how long until every parcel qualifies and what the difference is worth, with the full calculation shown so you can check it.
Why it matters
The 50% CGT discount turns on a single date, so the same sale can have materially different after-tax outcomes a fortnight apart. Seeing that before you sell is the whole point — and the step-by-step working is shown because a tax number you cannot verify is one you should not act on.
