Property Calculators

Property & Real Estate Calculators

Buying property means answering several different questions at once: what a lender will advance, what the government takes at settlement, and whether the numbers still work once you own the place. These nine calculators split that up into separate, checkable pieces. Everything runs in your browser, so the figures you type, your income, your deposit, what you paid, stay on your device.

What You Can Borrow, and What It Costs

The mortgage calculator turns a loan amount, rate, and term into a monthly repayment, a total interest figure, and a full amortisation schedule, so you can see how little of an early payment touches the principal. Canadian buyers should use the Canada mortgage calculator instead: Canadian fixed mortgages compound semi-annually rather than monthly by law, which makes a posted rate behave differently from the same number elsewhere, and it also handles CMHC insurance tiers. Working the other direction, the home affordability calculator starts from your income, existing debts, and deposit, and applies debt-to-income limits to estimate the purchase price you can carry.

The Tax Due at Settlement

Transfer duty is the cost buyers most often leave out, and it varies enormously by jurisdiction. The UK Stamp Duty (SDLT) calculator applies the slice bands used in England and Northern Ireland, where each portion of the price is taxed at its own rate rather than the whole amount at one. The Australia stamp duty calculator covers every state and territory, each with its own schedule, and accounts for first home buyer concessions and foreign purchaser surcharges.

Judging an Investment

The rental yield calculator separates gross yield from net, which is the distinction that decides whether a property earns anything: gross ignores rates, insurance, management fees, and vacancy, and net does not. The rent vs. buy calculator compares the two paths over time, weighing the opportunity cost of a deposit against capital growth and ownership costs, since buying is not automatically the cheaper option over a short horizon. For a development rather than a purchase, the Australia dual occupancy calculator models build costs, expected end value, and profit for duplex and dual occupancy projects, calculating stamp duty by state as part of the feasibility.

Reading Listings in Local Units

Korean property listings are quoted in pyeong rather than square metres, and the conversion is not a round number. The Korea pyeong calculator converts in both directions so you can compare a Korean listing with one priced per square metre.
