2026 Budget CGT CalculatorUpdated
The 2026 budget proposes the biggest change to capital gains tax in a generation. Compare the current rules with the proposed ones on an asset you already own — pre-2027 growth keeps the 50% discount, post-2027 growth moves to an indexed cost base with a 30% minimum rate.

You have a surplus to invest — does it end up worth more in your own name or inside a company? Weigh the tax on the way in, the growth, the capital gains treatment and the franked distribution on the way out, side by side.

- What is my family's spending budget?
- Do I have any surplus to invest?
- How will my assets grow by retirement age?
- Will I have enough to retire on?

Common questions
Are these calculators free to use?
Yes — free, no sign-up, no login. They run entirely in your browser and recalculate instantly as you change the inputs.
How accurate are the figures?
They are general estimates based on the assumptions you enter — simplified models that don't account for your personal circumstances. They're built for a clear first read of a decision, and the full picture is a conversation with the firm.
What happens when I leave my email?
We email you a summary of the figures you modelled, and send the same summary to M G Arthur & Associates so Manu or the team can pick up the conversation from your numbers — no obligation. We keep your email address and which calculator you used; the figures themselves aren't stored.
