How the monthly payment is calculated
The monthly principal and interest is an amortizing loan: each payment covers the interest due plus a slice of the balance, so the balance falls over time. Add property tax, insurance and maintenance for the true monthly cost (PITI).
Sydney housing facts
Sydney has some of the highest prices in the world (median near A$1.3m) and buyers pay stamp duty on purchase rather than an annual property tax. Australian mortgage rates follow the RBA cash rate. With rents also high, many Sydneysiders stay renting longer.
FAQ
How is the monthly mortgage payment calculated?
It is an amortizing loan: payment = loan × r(1+r)^n / ((1+r)^n − 1), where r is the monthly rate and n the number of months. Add tax, insurance and maintenance for the full monthly cost.
What does the rent-vs-buy break-even mean?
It is the number of years you would need to stay before buying costs less than renting, on the assumptions you entered. Stay longer and buying usually wins; move sooner and renting usually wins.
