A calculator is one input. A portfolio is a hundred.
Every tool here uses the same engine that runs inside Stackhold — the same DTI logic, the same LVR caps, the same rent-period defaults. So the numbers you see in a calculator are exactly the numbers you'll see in your portfolio model when you save the scenario.
That matters because real property decisions don't break down into single calculations. The right answer for "should I buy this?" depends on how it changes your DTI, your portfolio LVR, your overall cashflow, and your next-buy timeline — all at once. Stackhold runs every one of these calculators, simultaneously, across every property you own.
Use the standalone tools to scratch a quick itch. Open the full app when you want the answer to actually mean something.
