Saving for a house deposit takes more than putting money aside each payday. The best bank to save for house deposit in Australia depends on your balance, savings habits, interest rate and ability to meet bonus interest conditions.
This guide compares savings accounts using information from official bank websites. It also explains how bonus interest affects your savings timeline, how the First Home Super Saver Scheme may reduce your tax, and how to protect your deposit while preparing to buy.
Best Banks To Save House Deposit In Australia
The following comparison uses published information from the banks’ official websites, checked on 24 October 2026. Rates are variable and may change, so confirm the applicable rate before opening an account.
| Bank and Account | Published Interest Rate | Best For | Important Conditions |
| CommBank GoalSaver | 5.25% p.a. with bonus interest | Building a deposit through regular saving | Deposit during the month and finish with a higher balance than at the start, subject to the account’s terms. |
| NAB Reward Saver | 5.25% p.a. with bonus interest | Savers who can avoid withdrawals | Make at least one deposit during the month and make no withdrawals. |
| Westpac Life | 5.25% p.a. with bonus interest | People who save consistently each month | Deposit during the month and increase your balance by month-end. An eligible transaction account is also required. |
| NAB iSaver | 5.50% p.a. introductory rate | Eligible new customers seeking an introductory offer | The published rate applies for four months to eligible new customers who have not held an iSaver in the previous 12 months. The standard rate applies afterwards. |
| CommBank NetBank Saver | 5.50% p.a. introductory rate | Eligible new customers who want temporary higher interest | The introductory rate applies for five months to eligible new customers. The standard variable rate applies afterwards. |
Rates shown are annual rates published by the relevant banks. Introductory and bonus rates have different eligibility rules. Confirm the current rate, qualifying balance and applicable terms directly with each bank before deciding.
Which Bank Is Best For Your Savings Style?
- Best for regular saving: CommBank GoalSaver suits you if you can grow your balance each month and want a dedicated savings goal. Its bonus conditions reward consistent contributions.
- Best for avoiding withdrawals: NAB Reward Saver may suit you if you keep your deposit separate from everyday spending. However, an unexpected withdrawal can cost you the bonus for that month.
- Best for steady monthly growth: Westpac Life rewards eligible customers whose balances increase each month. Its linked transaction account requirement is worth considering.
- Best for a short-term boost: NAB iSaver and CommBank NetBank Saver advertise introductory rates. Compare their post-offer rates before choosing either account.
There is no universal winner for every saver. A slightly lower ongoing rate can outperform a higher headline rate if you regularly miss the qualifying conditions.
Key Takeaways
| Key Area | What You Need to Know |
| Choosing a bank | Compare ongoing interest rates, eligibility rules, fees and withdrawal conditions rather than headline rates alone. |
| Bonus interest | Some accounts require monthly deposits, balance growth or limited withdrawals, so missing a condition can reduce your earnings. |
| Deposit target | Your required deposit depends on the property price, lender criteria and whether you qualify for a low-deposit scheme. |
| First Home Super Saver Scheme | Eligible first-home buyers may save through superannuation and benefit from concessional tax treatment. |
| Tax and purchase costs | Budget for stamp duty, conveyancing, inspections and other expenses alongside your deposit. |
| Deposit protection | Eligible deposits held with authorised Australian banks are generally covered up to $250,000 per account holder, per institution, under the Financial Claims Scheme. |
| Best strategy | Match your account to your savings habits, automate contributions and review the total cost of buying, not just the deposit. |
How To Compare High-Interest Savings Accounts
A savings account should support your deposit timeline, not complicate it. Therefore, look beyond the advertised percentage before transferring your money.
Compare The Ongoing Rate
The high-interest savings accounts market includes products with introductory, bonus and standard variable rates. Each structure affects how much interest you actually receive.
An introductory rate usually lasts for a set period. After that, your earnings depend on the standard rate and any continuing conditions.
A bonus rate depends on meeting specified requirements. These may include monthly deposits, balance growth or restrictions on withdrawals.
The standard rate is especially important if your savings routine changes. It determines what you earn when you fail to qualify for a bonus.
Check Fees And Account Requirements
Before opening an account, review these features:
- Monthly account fees: Fees reduce your effective return, particularly when your balance is still small.
- Linked transaction accounts: Some savings products require another account, which may have separate fees or eligibility rules.
- Minimum and maximum balances: Certain products restrict the balance eligible for their highest rate.
- Access to funds: Withdrawal rules matter when you need to pay a deposit, settlement costs or an unexpected expense.
- Interest payment timing: Most savings accounts calculate interest daily and pay it monthly, but you should confirm the product’s terms.
The Australian Government’s Moneysmart savings account guide explains how to compare rates, fees, balance requirements and bonus conditions.
Consider How You Actually Save
The best account depends on your financial habits as much as its interest rate.
If you receive regular wages, an account rewarding monthly balance growth may fit your routine. However, it may be unsuitable if you regularly move money between accounts.
Alternatively, an account without monthly bonus requirements may offer more flexibility. That can help if your income varies or you need occasional access to your savings.
How Bonus Interest Can Delay Your Deposit
Bonus interest can make a meaningful difference to your savings. However, complicated conditions can also reduce your earnings when you miss a requirement.
Consider a saver who has accumulated $40,000 and adds $1,500 monthly. Their account offers a total rate of 5.25% p.a. when bonus conditions are met.
If the saver qualifies every month, their interest can compound as the balance grows. If they miss a qualifying month, the bank may pay only the much lower standard rate.
Example Of Missing Bonus Interest
Assume the account has a 0.10% p.a. standard rate and a 5.15% p.a. bonus component. These rates match the published structure of CommBank GoalSaver.
On a $40,000 balance, a simplified annual comparison looks like this:
| Interest Scenario | Approximate Interest Over One Year |
| Total rate of 5.25% p.a. | $2,100 |
| Standard rate of 0.10% p.a. | $40 |
| Difference | $2,060 |
These figures assume a constant $40,000 balance and unchanged rates for the entire year. Actual earnings depend on daily balances, deposits and the number of qualifying months.
One missed month will not normally erase an entire year’s interest. Nevertheless, repeated failures can significantly reduce your return.
How To Avoid Losing Bonus Interest
- Automate your deposits: Schedule a transfer after payday so you do not forget a monthly contribution.
- Read the withdrawal rules: Some accounts remove bonus eligibility after any withdrawal, even when you later replace the money.
- Check the calendar: Banking days, weekends and public holidays can affect when transactions count.
- Review your statements: Confirm that the bank applied the expected rate after each qualifying period.
Most importantly, do not leave yourself without emergency cash just to protect a bonus. Keep an accessible emergency fund separate from the money you need for your property purchase.
How Much Interest Can You Earn While Saving?
The interest you earn depends on your starting balance, regular contributions, rate and saving period. Even small differences in interest can add up when you save consistently.
Consider a buyer targeting a $900,000 property and saving towards a 20% deposit. The target deposit is $180,000, excluding purchase costs.
Suppose they start with $30,000 and save $2,000 monthly. For illustration, assume a constant 5% annual interest rate, monthly contributions and monthly compounding.
| Saving Period | Approximate Savings Balance |
| Starting balance | $30,000 |
| After 1 year | $56,900 |
| After 3 years | $115,900 |
| After 5 years | $181,800 |
These are estimates, not bank quotes. Actual results will differ as rates change and interest compounds under each account’s terms.
The example shows why your savings rate matters. However, your monthly contributions remain the main driver of progress.
Compare Two Interest Rates
Suppose you save $2,000 monthly for five years, starting with $30,000. A higher rate may help you reach your target sooner.
A rate of 5% could produce approximately $181,800. At 4%, the balance would be approximately $175,000, assuming the same contribution schedule and calculation method.
The difference is about $6,800 over five years. That could cover part of your conveyancing, inspections or other purchase expenses.
However, rates will rarely remain unchanged for five years. Treat these figures as illustrations rather than forecasts.
First Home Super Saver Scheme And Tax Savings
A bank account is not the only way to build your deposit. Eligible first-home buyers may also use the First Home Super Saver Scheme (FHSS).
The scheme allows eligible voluntary super contributions to be released for an eligible first-home purchase. Depending on your income and contribution type, this may offer tax advantages compared with saving entirely from after-tax income.
How The FHSS Scheme Works
The scheme allows eligible voluntary contributions of up to $15,000 per financial year, with a $50,000 maximum across all years.
You may make eligible contributions through salary sacrifice or personal voluntary contributions. The amount available for release depends on the contribution type and the scheme’s rules.
For eligible concessional contributions, the super fund generally applies 15% contributions tax. Your assessable released amount also benefits from a 30% tax offset when calculating the relevant tax treatment.
This may make the scheme attractive if your marginal income tax rate exceeds the contributions tax rate. However, the outcome depends on your circumstances.
Example Of Potential Tax Savings
Suppose you earn $100,000 annually and salary-sacrifice $10,000 into super for a future first-home purchase.
For illustration, assume a 30% marginal income tax rate plus a 2% Medicare levy. Your marginal rate is therefore 32%, before considering other circumstances.
| Calculation | Approximate Amount |
| Gross salary-sacrifice contribution | $10,000 |
| Contributions tax at 15% | $1,500 |
| Contribution remaining in super | $8,500 |
| Income tax and Medicare levy potentially avoided before release tax | $3,200 |
The $3,200 figure represents the initial difference between the assumed marginal tax rate and zero tax on that salary amount. It is not the final tax saving from using FHSS.
The eventual outcome depends on the FHSS release calculation, associated earnings, the 30% tax offset and your tax position. You should compare the full outcome against ordinary savings before choosing a strategy.
Important FHSS Conditions
The FHSS scheme is not a regular bank account. You must satisfy eligibility and release requirements before accessing the money.
- First-home eligibility: You generally must meet the scheme’s first-home ownership rules, although a financial hardship exception may apply.
- Contribution limits: Eligible voluntary contributions are capped at $15,000 annually and $50,000 across all years.
- Release timing: Request an FHSS determination before ownership transfers to you, and follow the ATO’s release process.
- Occupancy requirements: You must genuinely intend to live in the property and satisfy the scheme’s occupancy rules.
- Super fund rules: Check your fund’s processes, fees and insurance implications before making contributions.
The FHSS scheme can complement a bank savings account. However, it should not replace money you need for immediate access or emergency expenses.
How Much Deposit Do You Need?
Your deposit target depends on the property price, lender requirements and any government scheme you qualify for. A 20% deposit is a common goal because it can help you avoid lenders mortgage insurance (LMI).
LMI generally protects the lender if you cannot repay the loan. It does not protect you against losing your home or being unable to make repayments.
Some lenders may accept a smaller deposit, subject to their policies and your financial position. Eligible buyers may also qualify for government-backed deposit schemes.

Deposit Examples For Different Property Prices
| Property Price | 5% Deposit | 10% Deposit | 20% Deposit |
| $800,000 | $40,000 | $80,000 | $160,000 |
| $900,000 | $45,000 | $90,000 | $180,000 |
These figures cover the deposit only. You will need additional funds for applicable purchase costs and any other lender requirements.
A smaller deposit may mean a larger loan and higher repayments. It can also lead to LMI unless an exemption or eligible scheme applies.
Budget For Costs Beyond Your Deposit
Your savings goal should include more than the amount paid towards the purchase price.
- Stamp duty: State and territory duties vary according to the property, price and buyer eligibility. First-home buyer concessions may reduce the amount payable.
- Conveyancing and legal fees: You will usually need professional help to review contracts and complete the transfer.
- Building and pest inspections: These inspections can identify problems before you commit to the property.
- Loan establishment costs: Some lenders charge application, valuation or settlement fees, so review the applicable fee schedule.
- Moving and immediate repairs: You may need funds for removalists, essential appliances or urgent maintenance after settlement.
Should You Use A Term Deposit Instead?
A term deposit locks your money away for an agreed period at a specified interest rate. It can suit savers who know when they will need their funds and want more certainty.
However, accessing the money early may require notice or reduce the interest you receive. This matters when a property opportunity arises unexpectedly.
A high-interest savings account usually offers easier access. Its variable rate can rise or fall, but you can often move funds without breaking a fixed term.
You could divide your savings between both options. Keep the amount needed for near-term expenses accessible, and consider a term deposit only for money you can leave untouched.
Compare the maturity date with your expected purchase date. You should not risk delaying settlement because your savings remain locked away.
What Does The RBA Cash Rate Mean For Your Savings?
The RBA cash rate influences borrowing costs and can affect banks’ savings rates. However, banks do not have to change savings rates by the same amount as the Reserve Bank.
When the cash rate rises, banks may increase savings rates to attract deposits. Some may change introductory offers or bonus components instead of increasing every account’s standard rate.
When rates fall, your savings account may earn less even if you keep the same balance. Therefore, review your account regularly rather than assuming today’s rate will last.
The Reserve Bank of Australia publishes monetary policy decisions and explains changes to the cash rate. Check its official announcements when reviewing your savings strategy.
Protect Your Deposit While You Save
Your deposit may represent years of disciplined saving. Protecting it is therefore as important as earning a competitive return.
The Australian Government’s Financial Claims Scheme generally protects eligible Australian-dollar deposits up to $250,000 per account holder, per authorised institution. The limit applies to your combined eligible deposits with that institution, including accounts under different trading names.
If your savings exceed $250,000, check how the guarantee applies across your accounts and banking institutions. Do not assume separate brand names mean separate protection limits.
Also, keep your deposit separate from speculative investments if you expect to buy soon. Shares and cryptocurrency can fall sharply when you need the money.
Choosing The Right Savings Strategy
The best account combines a competitive rate with conditions you can reliably meet. Start by setting a realistic deposit target and estimating when you want to buy.
Then compare ongoing rates, bonus rules, access requirements and introductory offers. Calculate your expected return using your likely balance and contribution schedule, rather than relying on the advertised maximum.
If you qualify, consider whether FHSS contributions could improve your after-tax savings. At the same time, keep enough accessible money for emergencies and upcoming purchase costs.
Finally, review your account at least every few months. If rates change or your circumstances shift, another product may better support your goal.
Saving for a property is a long-term financial decision. A simple strategy you can maintain consistently is often more useful than chasing a headline rate with complicated conditions.
Final Thoughts
Choosing the best bank to save for house deposit in Australia involves more than finding the highest advertised rate. You need an account that rewards your saving habits, gives you suitable access to your money and supports your target purchase date.
Compare ongoing rates alongside introductory offers, bonus conditions and fees. Consider the FHSS scheme if you qualify, and include purchase costs in your savings goal.
Most importantly, build a strategy you can maintain. Regular contributions, careful budgeting and periodic rate reviews can help you grow your deposit while protecting the money you have already saved.
Frequently Asked Questions
Which Bank Has The Best Savings Account For A House Deposit In Australia?
The best bank depends on your balance and saving habits. CommBank GoalSaver, NAB Reward Saver and Westpac Life advertise competitive bonus rates, while introductory accounts may offer higher temporary returns. Compare current rates and conditions before choosing.
Is It Better To Save For A Deposit In A Savings Account Or Super?
A savings account offers accessible funds and straightforward interest earnings. The FHSS scheme may offer tax advantages for eligible first-home buyers, but withdrawals follow specific rules. Some buyers benefit from using both approaches.
Can I Buy A House With A 5% Deposit?
Yes, some lenders accept a 5% deposit, subject to their lending criteria. Eligible buyers may also access government-backed deposit schemes. However, a smaller deposit can increase your borrowing costs and may require LMI.
How Much Should I Save For A $900,000 House?
A 5% deposit is $45,000, a 10% deposit is $90,000, and a 20% deposit is $180,000. You should also budget for stamp duty, legal fees, inspections and other purchase expenses.
Do I Pay Tax On Interest Earned In A Savings Account?
Generally, interest earned on a personal savings account is assessable income. Your bank may report the interest to the ATO, and you must include taxable interest in your tax return. Your final tax depends on your circumstances.
Can I Withdraw Money From A Bonus Interest Account?
Usually, yes, but the withdrawal may affect your bonus interest eligibility. Some accounts require you to make no withdrawals during the qualifying month. Read your bank’s terms before moving money.
Is A Term Deposit Better Than A High-Interest Savings Account?
A term deposit may suit you if you can leave your money untouched for a fixed period. A savings account generally offers more flexibility when your purchase date is uncertain. Compare rates, access rules and early withdrawal conditions.
Should I Keep My House Deposit In One Bank?
One account can make tracking your savings easier. However, you should consider the Financial Claims Scheme limit if your eligible deposits exceed $250,000 at one institution. Review your bank’s protection status and account conditions.
