Enter your property price, deposit, and interest rate to instantly see your estimated repayments — monthly, fortnightly, or weekly. The calculator covers both Australian and New Zealand purchases with all country-specific costs built in: stamp duty, LMI, legal fees, building and pest inspections. Results update in real time as you type.
Stamp duty (transfer duty) is typically the largest single upfront cost when buying property in Australia. Rates follow a progressive bracket schedule set by each state, and first home buyers qualify for full exemptions or concessional rates in most states:
Select your state in the calculator and enable the First Home Buyer toggle to see your exact stamp duty figure and how much you save versus the standard rate.
Beyond stamp duty concessions, several government schemes reduce the cash you need upfront:
LMI is required when your deposit is less than 20% of the purchase price (LVR above 80%). It protects the lender — not you — if you default on the loan. Premiums are a percentage of the loan amount and rise steeply above 90% LVR; they can typically be capitalised into the loan balance. This calculator estimates LMI using published Helia / QBE indicative rates — actual premiums vary by lender and insurer.
APRA requires lenders to check whether you could still service your mortgage if interest rates rose by 3 percentage points. If you apply for a loan at 6.00%, the bank must verify you can afford repayments at 9.00%. The Rate Stress Test card in this calculator shows your projected repayment at +1%, +2%, and +3% above your entered rate — letting you model the APRA scenario and understand your buffer before you apply.
With a Principal & Interest loan, each repayment reduces both the interest and the principal — the loan is fully repaid at the end of the term. With an Interest Only loan, repayments cover only the interest; the principal is unchanged and must be repaid or refinanced when the IO period ends. IO loans have lower short-term repayments but significantly higher total interest over the life of the loan.
New Zealand has no stamp duty, keeping upfront costs lower than in Australia. Budget for legal fees (~$2,000), a LIM report from your council (~$350), a building inspection (~$700), and a registered valuation (~$750). The RBNZ imposes LVR restrictions — most owner-occupier borrowers need at least 20% deposit. The First Home Loan scheme allows eligible buyers to borrow with as little as 5% deposit if household income is under $95,000 (single) or $150,000 (joint) and the property falls within regional price caps.
Repayments use the standard amortization formula: P × r(1+r)ⁿ / ((1+r)ⁿ − 1) where P is the loan principal, r is the periodic interest rate (annual rate ÷ repayment frequency), and n is the total number of repayments. A $600,000 loan at 6.00% P&I over 30 years gives monthly repayments of approximately $3,597.
Your total cash required = deposit + stamp duty + legal fees (~$1,800) + building inspection (~$500) + pest inspection (~$300) + LMI (if LVR > 80%). The Upfront Costs section of the calculator shows a full breakdown — fees & outlays subtotal, your deposit, and the total cash required in one figure.
Yes. Usable equity is 80% of your existing property's current value minus any outstanding mortgage. Enable the Investor Equity toggle in the calculator, enter your property value and remaining mortgage balance, and the calculator shows exactly how much equity is available to use as your deposit on a new purchase.
