Property Purchase Calculator
Calculate your deposit, deposit percentage, loan amount and Loan-to-Value Ratio (LVR) for an Australian property purchase, and estimate the other buying costs you will need on top of the deposit — conveyancing, inspections, lender fees and more — all in one place.

Stamp duty rates, government fees, grants and first-home buyer concessions are set by each state and territory government and change regularly. Do not rely on any third-party stamp duty calculator without verifying with your state's revenue office or a licensed conveyancer.
How to Use This Calculator
- 1Enter the Property Purchase Price — the amount you expect to pay for the property.
- 2Enter either a Deposit Percentage or a Deposit Amount. The calculator keeps the two in sync, so updating one updates the other.
- 3Click Calculate to see your deposit amount, deposit percentage, estimated loan amount and Loan-to-Value Ratio (LVR), plus an LVR gauge showing whether Lenders Mortgage Insurance (LMI) is likely.
- 4Review the Estimated Other Buying Costs allowances (conveyancing, inspections, bank fees and more). These are editable estimates to help you budget for the costs beyond your deposit — they are not official government fees.
- 5Use the Stamp Duty Calculator separately to estimate transfer duty, because stamp duty varies by state and buyer type and is not included here.
What the Results Mean
This calculator shows how your deposit and purchase price combine into your loan amount and Loan-to-Value Ratio. It does not assess whether you will be approved — that is a separate lender assessment.
- Deposit amount & deposit %
- How much cash you are putting in upfront, and what share of the purchase price that represents. Most Australian lenders want at least 5–20% as a genuine deposit.
- Estimated loan amount
- The purchase price minus your deposit — the amount you would borrow. Note that your lender will assess your borrowing capacity separately and may lend less.
- Loan-to-Value Ratio (LVR)
- Your loan amount divided by the property value, shown as a percentage. It is the single most important number for LMI: an LVR above 80% usually means LMI applies.
- LVR gauge
- A colour-coded guide: green at or below 80% (standard lending), amber above 80% (LMI may apply), red above 90% (higher risk, LMI likely). Lender policies vary — this is a guide, not an approval.
- Other buying costs & total before stamp duty
- Your editable allowances added together. They help you see the cash you need on top of the deposit, but they are estimates — confirm actual costs with your conveyancer and lender.
Four Realistic Buyer Scenarios
Example 1 — $750,000 with a 20% deposit
An established home buyer puts down a 20% deposit on a $750,000 property.
- Purchase price$750,000
- Deposit$150,000 (20%)
- Estimated loan$600,000
- LVR80.00%
- LMI likely?No (typically)
At an LVR of 80% most lenders do not require LMI, making this the most common target deposit for buyers trying to avoid it.
Example 2 — $900,000 with a 10% deposit
A buyer purchasing a $900,000 home with a 10% deposit.
- Purchase price$900,000
- Deposit$90,000 (10%)
- Estimated loan$810,000
- LVR90.00%
- LMI likely?Yes (typically)
With a 90% LVR, LMI usually applies and adds to the cost of the loan — often capitalised into the loan balance or paid upfront.
Example 3 — First home buyer, $700,000, 5% deposit
A first home buyer purchases a $700,000 home with only a 5% deposit.
- Purchase price$700,000
- Deposit$35,000 (5%)
- Estimated loan$665,000
- LVR95.00%
- LMI likely?Yes (typically)
A 5% deposit is possible for some eligible buyers, but LMI is usually required. Some first home buyers may access a government guarantee that lets them buy with a smaller deposit and avoid LMI — check eligibility with your state revenue office and lender.
Example 4 — Investor, $800,000, 20% deposit
An investor buying an $800,000 investment property with a 20% deposit.
- Purchase price$800,000
- Deposit$160,000 (20%)
- Estimated loan$640,000
- LVR80.00%
- First-home concession?No (investor)
Investors are not eligible for first-home buyer concessions. Many lenders also require a larger deposit for investment loans (often 10–20%), and some states apply additional land tax or surcharges to investment property.
Common Mistakes to Avoid
- Confusing the deposit with the full funds needed. You also need to cover stamp duty, legal and inspection costs, and usually a buffer — these sit on top of the deposit.
- Assuming an 80% LVR is always "safe". Lender policies, the property type and your situation all affect whether LMI is required and the rate you are offered.
- Forgetting that your borrowing capacity may be lower than the estimated loan. Lenders apply their own serviceability tests to income, expenses and existing debts.
- Treating the buying-cost allowances as quotes. They are editable estimates; actual conveyancing, inspection and bank fees vary by provider, state and property.
- Leaving stamp duty out of your budget. Transfer duty can be tens of thousands of dollars and is usually payable at or before settlement — estimate it with the Stamp Duty Calculator.
- Underestimating the buffer. Lenders and advisers often suggest keeping 3–6 months of expenses in reserve so a rate rise or a gap in income does not put the loan at risk.
