About this calculator
Queensland charges transfer duty on a home-concession scale for owner-occupiers that sits well below the general scale: 1% up to $350,000, then 3.5% to $540,000 and 4.5% to $1,000,000. On a $650,000 Brisbane home the home-concession duty is $15,100, against $22,275 at general rates — this calculator uses the home rates, because it assumes you are buying a place to live in.
First home buyers get Queensland's headline settings. For established homes, duty is zero up to $700,000 and the concession phases out by $800,000. For brand-new homes — and vacant land you build on — first home buyers pay no duty at any price for contracts from 1 May 2025. Tick both boxes above (first home buyer + brand-new home) and the duty line goes to $0 whatever the price.
How to use it
- Enter the property price and your deposit — the difference, plus any LMI, is the loan amount.
- Add the interest rate and loan term (30 years is the Australian standard).
- If you will keep savings in an offset account, enter the average balance — you will see the interest it saves and how much sooner the loan ends.
- Tick "first home buyer" if it applies: the stamp duty below then uses your state's first-home concessions.
- Read the monthly repayment, the stamp duty and the real payoff time with your offset.
The formula
M is the monthly repayment, P the loan amount, r the monthly rate and n the number of payments. An offset account does not change the repayment; it reduces the balance on which interest is charged, so more of each repayment becomes principal and the loan ends sooner. Stamp duty is charged by the state on the purchase price using that state's banded table.
Worked example
A $650,000 Brisbane home with a $130,000 deposit (20%) leaves a $520,000 loan — $3,117 a month at 6.00% over 30 years. Home-concession duty is $15,100; as a first home buyer it is $0, because $650,000 sits under the $700,000 threshold. If the same buyer chose a brand-new $950,000 townhouse instead, duty would still be $0 under the new-build exemption, while an upgrader would pay $28,600.
Frequently asked questions
How much is transfer duty on a $650,000 home in Queensland?
At home-concession rates: $3,500 on the first $350,000, plus 3.5% of the next $190,000 ($6,650), plus 4.5% of the remaining $110,000 ($4,950) — $15,100 in total. First home buyers pay nothing at this price; investors and upgraders who do not qualify for the home concession pay general rates of $22,275.
Are first-home new builds really duty-free at any price in Queensland?
Yes — for contracts entered from 1 May 2025, the Queensland government removed the value cap on the first home buyer concession for new homes and vacant land to build on. You still need to meet the usual conditions: first home, Australian citizen or permanent resident, and you must move in and live there (within 12 months for a new build, and build and move in within the set period for land).
What happens between $700,000 and $800,000 for first home buyers?
The concession for established homes tapers across that band: the closer to $800,000, the closer the duty gets to the full home-concession amount. This calculator phases the home-concession duty in linearly across the band, which closely tracks the official tapering deduction — check your exact figure with the QRO calculator before settlement.
Do I still get the Queensland First Home Buyer Grant?
The grant is separate from duty: Queensland has offered a grant for new homes (recently $30,000 for eligible contracts) with its own price caps. It does not change the duty in this calculator — treat it as a cash-back bonus on top if you qualify.
What formula does this home loan calculator — queensland calculator use?
M = P × r(1 + r)^n ÷ ((1 + r)^n − 1), interest charged on (balance − offset) M is the monthly repayment, P the loan amount, r the monthly rate and n the number of payments. An offset account does not change the repayment; it reduces the balance on which interest is charged, so more of each repayment becomes principal and the loan ends sooner. Stamp duty is charged by the state on the purchase price using that state's banded table. The worked example on this page applies the formula step by step with real numbers, so you can verify the result by hand.
