Home Deposit Calculator
Work out the house deposit needed at your chosen loan-to-value ratio, plus the upfront costs you enter, with the savings gap and every step of the arithmetic.
Stamp duty, legal, inspections and other costs you enter yourself. The stamp duty calculator can estimate the duty component.
How long it takes to save
Blank leaves the deposit figure exactly as it is above; fill these in to see the time to reach it.
Zero treats the balance as cash set aside.
Enter the property price and target LVR to see the deposit needed.
Summary
Enter the property price and target LVR to see the deposit and the working behind it.
Working
- loan = property price × target LVR
- deposit = property price − loan
- cash needed = deposit + the upfront costs you entered
- time to reach it: the savings engine runs monthly deposits on what you have saved, and the first year boundary at or above the cash needed is reported
- save per month: the closed-form deposit that reaches the cash needed over each timeframe, rounded up to the next cent
Assumptions
- LVR is measured against the price you enter. Lenders assess against their own valuation, which can be lower.
- Upfront costs are your figures; nothing is estimated for you on this route.
- The savings projection assumes deposits are made in full every month, at the end of the month, at a constant rate, with no withdrawals.
Limitations
- Lenders mortgage insurance, guarantor arrangements, first-home schemes and lender-specific LVR caps are not modelled.
- Property prices move, so the cash needed on the day is not the cash needed today.
- Result accuracy class A: deterministic arithmetic on the figures you enter.
Common questions
How much deposit do I need to buy a house in Australia?
The deposit follows from the property price and the loan-to-value ratio you are borrowing at: the loan is the price times the LVR, and the deposit is the remainder. This calculator works it out for the LVR you choose and also lays out the same price at each of the LVR bands lenders commonly reference, so you can see how the deposit moves band by band. It then adds the upfront costs you enter to give the total cash needed.
Is the deposit the only cash I need at settlement?
No. Transfer duty, conveyancing, inspections, loan fees and any lenders mortgage insurance are payable on top, which is why this calculator reports total cash needed as deposit plus the costs you enter. It does not source those costs for you. The property buying costs calculator prices duty from the published rates for your state and lets you add the rest.
How long will it take to save a house deposit?
Enter what you have saved so far, what you save each month and the interest your savings earn, and the calculator projects the balance forward until it reaches the deposit plus costs, reporting the amount still to save. The projection compounds the interest rate you enter on the growing balance rather than assuming a flat rate of accumulation. It makes no allowance for changes in the property price while you save.
What deposit avoids lenders mortgage insurance?
Lenders generally require LMI above a threshold loan-to-value ratio, and both the threshold and the premium are set by each lender and insurer rather than by statute, so this calculator does not assert one. What it shows is the deposit and loan implied by each common LVR band on your price. Check the ratio itself in the LVR calculator and ask your lender for their threshold and premium.
Does a bigger deposit reduce my repayments?
A larger deposit means a smaller loan, and a smaller loan carries a lower repayment and less total interest at the same rate and term. This calculator reports the loan amount for each deposit and LVR band; to price the repayment and lifetime interest on that loan amount, run it through the mortgage repayment calculator. A lower LVR may also affect the rate a lender offers, which is a matter for the lender rather than this calculation.
