Free Property Calculators Every Brisbane Home Seller Should Use
Most sellers do not run the numbers until they are already committed. These eight free tools take under five minutes each and tell you exactly where you stand before you sign anything.
Most Brisbane homeowners spend more time choosing kitchen tiles than modelling the financial outcome of their sale. The numbers are not complicated, but they are often surprising, and it is much better to find out what they look like before you sign an agency agreement than after.
All of the calculators below are on the tools page, free, require no login, and take under five minutes each. Running through all of them before you meet with an agent gives you an informed baseline for every conversation you will have about your sale.
Start with an indicative value
Before you can model anything else, you need a working number for what your property might achieve. The instant valuation tool generates a model-based estimate using recent comparable sales data. Treat it as a starting point, not a final number. Automated valuations miss the things that matter most at an individual property level: land configuration, the quality of a renovation, aspect, and how comparable sales were actually selected. But it is a useful anchor for your modelling, and it takes thirty seconds.
For a more grounded starting position, the appraisal reality check is worth running once you have spoken to two or three agents. You feed in each quoted price range, test them against recent evidence, and the tool flags which estimates look credible and which look inflated. Agent quoting practices vary considerably across Brisbane's inner east, and having a structured way to compare them is useful before you commit to anyone.
Model your net position before anything else
The most important number for any seller is not the sale price. It is what lands in your account after commission, marketing, conveyancing, and any CGT liability. The selling cost calculator gives you a clean breakdown: agent commission at your expected percentage, a realistic marketing allowance, conveyancing costs, and styling. It is a fast way to test what a 2.2% versus a 2.5% commission structure actually costs on your specific sale price. The difference on a $1.3 million sale is $3,900 and worth knowing before you start negotiating.
For a more complete picture, the net proceeds deep dive goes further. It takes the same selling costs and layers in your outstanding mortgage balance, any fixed-rate break costs if applicable, pro-rata council rates and water charges at settlement, and CGT where relevant. The output is formatted like a settlement statement. Running it before you list means no surprises when your solicitor sends through the actual figures. For a detailed look at what goes into selling costs, the full cost of selling guide breaks down every line item.
The equity calculator answers the related question: what equity am I actually holding, and how much would I be taking to my next purchase? If you are buying again, this number feeds directly into your deposit strategy and borrowing position on the next property.
Capital gains: run this early
CGT is the number that most sellers think about last but should think about first. Whether your main residence exemption applies, whether you are inside the 50% discount window, and whether settling in this financial year versus next would cost or save you money can all affect your net position by tens of thousands of dollars.
The capital gains tax calculator walks through the main residence exemption and the 50% CGT discount using your own purchase price and anticipated sale price. Once you have a CGT estimate, the CGT-optimised sale timing tool lets you compare settling in this financial year against next. You enter a projected income for both years and it shows you the difference. For investment property sellers with other income to consider, this is worth running with your accountant alongside it. The detailed Brisbane CGT guide covers the rules behind the exemptions if you want the full picture.
The full cost of moving
If you are selling and buying, the selling costs calculator only tells you half the story. The stamp duty calculator gives you the Queensland transfer duty figure on your next purchase, including any first home buyer concessions if they apply. It is a frequently underestimated cost: transfer duty on a $1.1 million purchase in Queensland is around $38,000, and on a $1.5 million purchase it is closer to $61,000.
The whole-of-move maths tool pulls it all together. You enter your current property, your expected purchase price, your moving costs, and an estimate of lost rental income during the transition. The output is an end-to-end net cash position after the move. It is the calculation most people never run, and it regularly changes how sellers think about their upgrade or downsizing budget.
If timing is tight and you are considering buying before you sell, the bridging and relocation finance calculator shows three scenarios side by side: buy first with bridging finance, sell first and rent while you search, or try to settle simultaneously. The differences in total cost between scenarios can be significant depending on how long you expect to carry two properties.
During your campaign
Once your property is on the market, one calculator is worth keeping open: the holding costs tool. It calculates the real weekly cost of being on the market, combining mortgage interest, council rates, insurance, ongoing styling costs, and the opportunity cost of the equity you are not yet deploying. In Brisbane's inner east, the difference between a three-week campaign and a seven-week one regularly represents $8,000 to $15,000 in holding costs on a typical home. It is a useful number to have in front of you when you are weighing whether to accept an offer or hold out for another inspection round.
All of them in one place
The calculators page has all of these tools plus others covering mortgage repayments, borrowing power, investment yield, negative gearing, and more. They are free, no login required, and most take under five minutes. The best time to run them is before you book any agent appraisals, so you are working from your own informed baseline rather than relying on numbers provided by people with an interest in your decision.
