For redraw vs offset, choose an offset for regular spending access and consider redraw when a cheaper loan suits money you can leave repaid. If your home could become a rental, consider the tax effect before paying spare cash into the loan.
Redraw and Offset at a Glance
An offset holds a separate deposit, while extra repayments reduce your loan debt and may become available through redraw. Both reduce interest, but your right to use the money comes from different account terms.
| Decision factor | Offset account | Redraw facility |
|---|---|---|
| Where spare cash sits | In a separate deposit account linked to the loan | Repaid into the loan, reducing the debt |
| Interest effect | A 100% offset reduces the balance charged interest by the eligible deposit balance | Extra repayments reduce the outstanding balance charged interest |
| Access | Transaction access under the deposit account terms | Access to the available amount under the loan’s redraw terms |
| Later private spending | Withdrawing your own savings does not itself create a new loan | A redraw is a new borrowing whose use affects interest deductibility |
The Moneysmart offset guide explains the account structure and costs. A loan can have both features, so you can hold spending money separately while making extra repayments.
Compare Interest Savings With Product Costs
Compare total interest and fees using the cash balance you expect to retain, rather than your balance on payday.
In this simplified example, the starting loan is $500,000 and the rate is 6% a year. Ignore scheduled principal repayments and fees initially. Hold the spare cash for a full year.
| Setup | Loan debt | Offset deposit | Balance charged interest | Annual interest |
|---|---|---|---|---|
| No spare cash applied | $500,000 | $0 | $500,000 | $30,000 |
| $30,000 in a 100% offset | $500,000 | $30,000 | $470,000 | $28,200 |
| $30,000 extra repayment | $470,000 | $0 | $470,000 | $28,200 |
At the same rate, both save $1,800. Now suppose the offset loan costs 6.10% plus a $300 annual fee, while the redraw loan remains at 6% with no annual fee. These are assumed prices, not lender quotes.
With the same $30,000 buffer, the offset costs $28,970 in annual interest and fees. The redraw option costs $28,200, a $770 difference. The offset still saves interest against leaving cash unused, but costs more than applying that cash to the cheaper loan.
If spending reduces the average offset balance to $10,000, the saving at 6% is about $600 a year. Use daily balances for a closer estimate. Add monthly account charges and package fees, but count each fee once. A rate premium applies to the balance charged interest, not just the spare cash.
Understand Access and Lender Conditions
Redraw access depends on the available balance and your lender’s rules. It does not necessarily equal all the extra repayments you have ever made.
CommBank’s redraw information says available redraw can reduce over the loan term. Switching to a fixed-rate loan removes access during the fixed period. The bank lists no redraw fee on eligible loans.
Its redraw guide distinguishes access methods. Branch withdrawals have a $1,000 minimum, while electronic withdrawals have no minimum. Joint borrowers’ signing arrangements affect which channels they can use. A transfer into the loan can take up to one business day to become available for redraw, or longer from another bank.
Other lenders set different limits. IMB’s online redraw instructions specify a $500 minimum. These examples show why a blanket claim that redraw always takes days, or always has the same minimum, is unreliable.
To redraw from an eligible ANZ home loan, select the loan in ANZ Internet Banking and choose Redraw loan under Account actions. Check your available redraw and select a linked ANZ account to receive the funds. ANZ’s redraw instructions show how to review and confirm the transfer.
For everyday access, CommBank’s Everyday Offset supports debit-card, branch and online transactions. A separate deposit still has account conditions and transaction limits. Do not treat it as unrestricted access in every circumstance. Confirm the offset is linked to the intended loan and whether it offsets 100% of the eligible balance.
Check Tax Purpose Before Moving Money
A redraw is a new borrowing for tax purposes, so the use of the redrawn money affects whether its interest is deductible. The property securing the loan does not decide the answer by itself.
The ATO’s Taxation Ruling TR 2000/2 explains this treatment. Redrawing an investment loan for private spending creates a private-purpose portion. Interest on that portion is not deductible, and mixed-purpose debt needs apportionment.
Consider an illustrative home-to-rental move. You owe $500,000 on a loan used only to buy your home and have $50,000 of savings. You later rent the home out and use the $50,000 for your next private home.
- If you first repay $50,000 and later redraw it for the new home, the debt returns to $500,000. The $50,000 redraw has a private purpose, even though the original property is now rented.
- If you keep your own $50,000 in a genuine separate offset and withdraw it, the original loan debt stays $500,000. Spending those savings does not itself create a private-purpose redraw.
An offset does not make existing private debt deductible or repair earlier mixed borrowing. Deductions still depend on the loan’s use and the property’s income-producing use. The ATO’s rental-property interest guidance explains private-use apportionment. Before moving money, ask your tax adviser to assess the loan history and planned spending, using your statements and purchase records.
Choose for Your Cash Habits and Future Plans
Use an offset for money you regularly spend, provided its access and total cost fit your needs. Salary and bill payments can pass through the account while the remaining balance reduces interest.
For a buffer you rarely touch, redraw can suit a cheaper loan when its withdrawal rules meet your needs. Keep enough separately accessible cash for urgent expenses if the redraw process cannot deliver it in time. The redraw home-loan guide covers the facility in more detail.
If you plan to keep your home as a rental, discuss the future use of the cash with your tax adviser before making extra repayments. An offset can keep your savings separate from the debt, while the advice determines the deduction outcome.
Before changing the setup, obtain the rate for each eligible loan and its account or package charges. Confirm withdrawal limits and processing times, joint-signing requirements and what happens to access when the loan changes. Then compare costs against your actual spending pattern and the average buffer you can maintain.
