Everything you need to analyse
Aussie property

Five purpose-built calculators in one app — all free, all instant, no spreadsheets required.

Mortgage Calculator

Calculate repayments for principal & interest or interest-only loans. See a full amortisation schedule, compare extra repayments, and visualise how much interest you'll pay over the life of your loan.

P&I & IO loans

Rental Yield Calculator

Instantly calculate gross and net rental yield for any property. Factor in vacancy rates, annual expenses, and mortgage costs to see true net weekly cashflow — and find your break-even rent.
