Carefully built.
Every calculator is cross-checked against the ATO and tested at the boundaries that matter. A calculation that disagrees with the source is worse than none.

Statutory rates come from named sources. Other assumptions – return rates and inflation – are visible and adjustable.
No affiliate links or recommended lenders, brokers, funds, or ETFs. No sponsored products or commercial partnerships.
Built for adults checking their own numbers. No dark patterns or artificial urgency. Read the assumption, change it, and see what moves.
