Every asset comparison you've ever seen is misleading. They ignore leverage, ongoing cash hunger, tax, and costs. This one doesn't. Plug in your starting cash, choose the assets to compare, and see what each path actually returns on your money.
| Asset | Cash deployed | Cash returned (after CGT) | Net profit | Cash-on-cash multiple | Annualised return |

The leverage problem: A "6% property return" sounds lower than a "9% share return" — but property is bought with 5x leverage (20% deposit). Your cash in a $1M property at 6% growth doesn't grow at 6% — it grows much faster because you put in $200k and got the upside on $1M. The asset return is not the cash return.
The cash-hunger problem: Property typically needs ongoing top-ups during the negative gearing years (interest > rent). That's more of your cash flowing into the asset each year. Shares and ETFs pay you positive dividends. If you don't count the top-ups, property's leverage looks free. It isn't.
The honest comparison: For each asset, this calculator tracks:
Tax modelling: Property and shares/ETFs get the 50% CGT discount on capital gains held >12 months. Dividends are taxed at your marginal rate (less franking credits for ASX shares). Bond interest is taxed annually at full marginal. Crypto follows share rules. After 1 July 2027, proposed Budget 2026 rules apply indexation + 30% minimum tax — this calc uses current rules.
What this calculator deliberately doesn't model:
Use this for: Honest like-for-like comparison of where to put a lump sum. The defaults are defensible (long-run averages, current rates) but assumption sensitivity is real — change the numbers, see how robust your conclusion is. If property only wins at 7% growth but not 5%, both are plausible assumptions and you should hold that uncertainty.
