According to the Australian Prudential Regulation Authority’s (APRA) first-quarter 2026 data, total housing lending across Australia has surpassed $2.3 trillion, and around 68% of loan products come with a redraw facility. At the same time, the Reserve Bank of Australia’s (RBA) April 2026 monetary policy statement shows the cash rate held steady at 4.35%, with mortgage rates ranging between 6.15% and 7.80%. Against this backdrop, the redraw facility has become one of the core tools borrowers use to optimise cash flow and cut interest costs.
Redraw — the ability to withdraw extra repayments — lets borrowers access any amount paid above the minimum monthly repayment at any time. Unlike an offset account, redraw acts directly on the loan principal: interest is calculated on the remaining principal rather than on an account balance. Drawing on the latest 2026 policies, industry reports and real-world case studies, this article provides a complete reference covering how the mechanism works, tax implications, LMI links, fixed-rate restrictions and more.
How Redraw Works: Mechanism and Calculation Logic
The core mechanism of redraw is that when borrowers park extra repayments in the loan account, the principal falls and interest is recalculated on the remaining balance. For example, on a $500,000 loan at 6.50% with monthly repayments of $3,160, an extra $1,000 repaid each month reduces the principal to around $488,000 after a year, saving roughly $54 in monthly interest. Withdrawing extra repayments is done through the bank’s platform or an application and is usually credited instantly, though some institutions impose a minimum withdrawal amount (such as $500).
The calculation follows the simple interest formula: interest = remaining principal × annual rate ÷ 365 × days. Redraw does not create a separate account, and the interest saving shows up directly on the monthly statement. According to Canstar’s 2025 home loan report, borrowers who use redraw save an average of $1,200–$2,400 in interest per year, depending on the amount of extra repayments and the rate.
Note that withdrawing extra repayments can trigger fees. In 2026, among the big four banks, Commonwealth Bank charges a $30 fee per redraw, while Westpac, NAB and ANZ waive it on some products. Non-bank lenders such as ING and Macquarie usually charge nothing, but it is worth confirming the product terms.
Redraw vs Offset: Key Differences and How to Choose
Redraw and offset accounts are often discussed together, but the mechanisms are entirely different. Redraw directly reduces the loan principal, and interest is calculated on the remaining principal; an offset account is a separate deposit account whose balance is offset against the principal for interest purposes, without reducing the principal itself. According to Mozo’s 2025 comparison research, the average annual fee for an offset account is $395, while redraw usually has no annual fee — though withdrawals may be charged.
The right choice depends on your cash-flow needs. For frequent depositors and withdrawers, offset is more flexible: money is available at any time, no application is needed, and the available limit is untouched. For savers with a clear goal, redraw is better: extra repayments are locked into the loan, curbing spending impulses while cutting interest. In 2026, a RateCity survey found that 62% of borrowers choose redraw, mainly because it avoids additional account management fees.
On the tax side, redraw affects interest deductibility on investment loans. Under the Australian Taxation Office’s (ATO) 2025 guidance, if funds withdrawn via redraw are used for non-investment purposes (such as buying a car or travel), the interest on the corresponding portion is not deductible. Moving money in and out of an offset account does not change the loan principal, so it does not affect deductibility. Investment property borrowers should generally prefer an offset account to keep their interest deductions maximised.
Redraw Restrictions on Fixed-Rate Loans and How to Work Around Them
On fixed-rate loans, redraw is usually restricted. In 2026, average fixed rates range from 5.95% (1-year) to 6.40% (3-year), but most institutions cap extra repayments during the fixed term, typically at $5,000–$10,000 per year. Anything above that can trigger break costs — compensation the bank charges because the borrower has reduced the principal early.
For example, NAB’s 2026 fixed-rate products allow $10,000 of extra repayments per year, with break costs charged on anything above that for the remainder of the fixed term. Westpac bans redraw entirely during the fixed period, allowing it only once the term ends. Workarounds include: choosing a split loan, fixing part of the amount and leaving part variable, so the variable portion keeps the redraw facility. According to Finder’s 2025 data, 72% of split-loan borrowers use redraw to reduce principal once their fixed term ends.
In addition, once the fixed term ends, borrowers can withdraw accumulated extra repayments in one go — though the bank may adjust the rate. In 2026, ANZ allows a redraw balance to roll automatically into the variable principal when a fixed rate converts to variable, with no extra fee.
Redraw and LMI: How It Affects Mortgage Insurance Costs
The link between Lenders Mortgage Insurance (LMI) and redraw is often overlooked. LMI is a necessary cost when the loan-to-value ratio (LVR) exceeds 80%, usually 1%–4% of the loan amount. Because redraw reduces the principal, LVR falls and a borrower may move out of LMI territory. For example, on a $600,000 loan with an initial LVR of 90%, the LMI premium is about $18,000. If redraw reduces the principal to $540,000, the LVR falls to 81% — LMI still applies, but the premium may be lower.
In 2026, QBE’s LMI report shows that for every 5 percentage points LVR falls, LMI premiums drop by an average of 25%–35%. Note, however, that LMI is usually paid as a one-off and a lower principal after redraw does not trigger a refund. On a new loan application, if you plan to repay quickly, choosing a lower LVR can save LMI — for example, a 20% deposit plus 5% in extra repayments brings LVR to 75% and avoids LMI altogether.
Real-world case: Sydney buyer Mr Zhang borrowed $800,000 at 85% LVR, with an LMI premium of $24,000. He made extra repayments of $2,000 a month and, after 18 months, his LVR fell to 79% — but the LMI had already been paid and could not be refunded. Had he put down a 25% deposit from the start, he would have saved the $24,000 LMI. Recommendation: high-LVR borrowers should use redraw to bring LVR down, while weighing the one-off LMI cost.
Comparing Major Institutions’ 2026 Redraw Policies
The big four banks differ markedly in their 2026 redraw policies. Commonwealth Bank offers free redraw, but each withdrawal has a $500 minimum and must be done through NetBank. Westpac allows unlimited free withdrawals, but only on variable-rate loans. NAB imposes no cap on extra repayments but restricts them to $10,000 per year during a fixed term. ANZ offers real-time redraw, but withdrawals above $50,000 require manual review.
Among non-bank lenders, ING’s redraw is completely free with no minimum withdrawal. Macquarie allows instant withdrawal via its mobile app, but extra repayments only take effect once they reach $1,000. In Canstar’s 2026 product ratings, ING and Macquarie earned an “excellent” rating for their redraw facilities, thanks to zero fees and flexibility.
Differentiated policies: some institutions set an “available proportion” on the redraw balance. Bankwest, for instance, requires extra repayments to stay in the account for at least 30 days before they can be withdrawn. Suncorp charges a 0.5% annual fee on redraw balances above $100,000. Borrowers should read the Product Disclosure Statement (PDS) carefully to avoid hidden costs.
Tax Implications of Redraw: Investment vs Owner-Occupied Properties
For investment loans, redraw is tax-complicated. Under the ATO’s 2025 tax ruling (TR 2025/1), if redrawn funds are used for investment purposes (such as buying another property), the interest is fully deductible. If used for personal spending, the interest on the withdrawn portion is not deductible. Owner-occupied loans have no tax implications, because the interest on a home loan is not deductible.
Real-world case: Ms Li has a $600,000 investment loan at 6.50%. She makes extra repayments of $2,000 a month, building a redraw balance of $24,000 after a year. She withdraws $20,000 to renovate her owner-occupied home. The ATO rules that the interest attributable to that $20,000 is not deductible. At 6.50%, that means losing $1,300 in deductions each year. Recommendation: investment borrowers should use redrawn funds strictly for investment, or use an offset account to avoid the problem.
Record-keeping: borrowers should keep records of redraw withdrawals, including dates, amounts and purposes. The ATO accepts bank statements as evidence. In 2026, H&R Block tax experts noted that around 15% of investors face tax adjustments because of improper redraw withdrawals.
Redraw in Practice and Common Misconceptions
How to do it: 1. Log in to the bank’s platform and check the redraw balance on the loan account. 2. Confirm the withdrawal does not exceed the balance. 3. Choose the receiving account (usually the linked transaction account). 4. Confirm any fees. 5. Funds usually arrive within 1–2 business days. Common misconceptions include: treating the redraw balance as cash reserves (it must actually be applied for); ignoring fixed-rate restrictions; and thinking redraw affects your credit score (it does not).
Misconception 1: The redraw balance counts as savings. In fact, redraw is a reduction in loan principal; once withdrawn, the principal rises again and interest resumes. One borrower had a $50,000 redraw balance; after withdrawing it, the loan principal increased, and while the monthly repayment may stay the same, the interest increases.
Misconception 2: Redraw suits every borrower. For people with weak self-control who frequently dip into funds, offset is better. According to a 2025 ME Bank survey, 23% of redraw users had increased their debt after withdrawing on impulse.
Misconception 3: Redraw and offset produce the same returns. Take a $500,000 loan at 6.50% with $1,000 in extra repayments each month: redraw saves the same interest as offset (about $54/month), but an offset account’s $395 annual fee can eat into the benefit. The key to choosing: decide on account fees and how often you deposit and withdraw.
FAQ
Q1: Which is cheaper — redraw or offset?
A: If the account has no annual fee, the interest savings are identical. But offset accounts usually charge an annual fee (averaging $395/year), while redraw may charge a withdrawal fee (such as CBA’s $30 each time). For frequent depositors and withdrawers, offset is more flexible; for savers with a clear goal, redraw is better. In 2026, RateCity data shows 70% of borrowers choose redraw to save on account fees.
Q2: Can I use redraw on a fixed-rate loan?
A: Yes, but with restrictions. Most institutions cap extra repayments per year (e.g., $5,000–$10,000), and going above that may trigger break costs. NAB, for example, allows $10,000 of extra repayments per year. Consider a split loan — fix part of the amount and leave part variable, so the variable portion keeps the redraw facility.
Q3: Does withdrawing via redraw affect tax?
A: It depends on the purpose. If the funds are used for investment, the interest is deductible; if used for personal spending, it is not. The ATO’s 2025 ruling makes this clear. Investment borrowers are advised to use an offset account to avoid tax complications. Keep withdrawal records (date, amount, purpose) in case of audit.
Q4: Can I withdraw the redraw balance at any time?
A: Usually yes, but you need to apply through the bank’s platform. Some institutions set a minimum withdrawal (such as $500) or a waiting period (such as 30 days for extra repayments). After withdrawal, the loan principal rises and interest resumes. Confirm the product terms to avoid surprise fees.
Q5: How does redraw affect LMI?
A: Redraw reduces the principal, so LVR falls — but LMI is usually paid once and is not refunded. On a new application, if you plan to repay quickly, you can choose a lower LVR (such as 75%) to avoid LMI. In 2026, QBE’s LMI report showed that for every 5% fall in LVR, premiums drop by 25%–35%.
