The RBA's cash rate is at 4.10% following two rate hikes already in 2026 — and NAB announced on 15 May 2026 that it will increase variable home loan rates by 0.25%, effective immediately. If you're calculating repayments on a A$1,500,000 home loan right now, you're doing it in one of the most important rate environments for Australian borrowers in recent years. Here's what the numbers look like at current rates.
A$1,500,000 Home Loan Monthly Repayments — Current 2026 Rates
Based on the RBA cash rate of 4.10% and current lender pricing as of May 2026:
| Rate Scenario | Annual Rate | Monthly Repayment (30yr P&I) | Total Repaid over 30 Years | Total Interest Paid |
|---|---|---|---|---|
| Competitive lender (non-bank, low LVR) | 5.15% variable | A$8,190 | A$2,948,542 | A$1,448,542 |
| Big 4 bank (average variable) | 5.75% variable | A$8,754 | A$3,151,293 | A$1,651,293 |
| Higher rate scenario | 6.25% variable | A$9,236 | A$3,324,873 | A$1,824,873 |
| 25-year term (competitive lender) | 5.15% variable | A$8,900 | A$2,670,132 | A$1,170,132 |
The difference between the competitive lender rate (5.15%) and a higher big bank rate (5.75%) on a A$1,500,000 loan is A$6,758 per year — A$202,751 in total interest over 30 years. This is why comparing lenders matters enormously on a mortgage.
The RBA Rate Impact on Your A$1,500,000 Mortgage
The RBA has increased the cash rate twice in 2026 — reversing the three cuts of 2025. Each 0.25% increase in the cash rate adds approximately A$312/month to repayments on a variable A$1,500,000 loan. Here's how rate movements affect your monthly repayment:
| Cash Rate | Typical Variable Rate | Monthly Repayment | Change from Current |
|---|---|---|---|
| 3.85% (pre-2026 hikes) | 5.40% | A$8,423 | A$+233/month |
| 4.10% (current — May 2026) | 5.65% | A$8,659 | Current |
| 4.35% (one more hike) | 5.90% | A$8,897 | A$+239/month |
| 4.60% (two more hikes) | 6.15% | A$9,138 | A$+480/month |
What You Need to Borrow A$1,500,000 in Australia
Australian lenders assess home loan applications based on your income, existing debts, and living expenses — not just the property value. The standard serviceability rules:
Income requirement: Most lenders apply a debt-to-income ratio cap and a serviceability buffer. APRA requires lenders to assess your ability to repay at your actual rate plus 3%. For a A$1,500,000 loan at 5.65% variable, the assessment rate is 8.65% — meaning your income needs to support repayments of approximately A$11,694/month from a serviceability perspective.
LVR (Loan-to-Value Ratio): Borrowing A$1,500,000 requires knowing your property's value. If the property is worth A$1,875,000, an A$1,500,000 loan represents 80% LVR — the threshold below which Lenders Mortgage Insurance (LMI) is not required. Below 80% LVR also typically unlocks the best rates.
Deposit: A 20% deposit on a property worth A$1,875,000 is A$375,000. First home buyers can access the First Home Guarantee (previously FHLDS) with as little as 5% deposit and avoid LMI on eligible purchases up to value thresholds that vary by state.
Additional Costs on a A$1,500,000 Home Purchase
| Cost | Estimated Amount | Notes |
|---|---|---|
| Stamp duty (NSW, not first home buyer) | ~A$82,500 | Varies significantly by state — NT and ACT cheapest, NSW and VIC highest |
| Lenders Mortgage Insurance (if LVR >80%) | A$0 with 20% deposit | Can add A$10,000–A$50,000+ if LVR is above 80% |
| Conveyancing/legal fees | A$1,500–A$3,000 | Varies by state and complexity |
| Building and pest inspection | A$400–A$800 | Essential before exchange — not optional |
| Home and contents insurance (first year) | A$1,500–A$4,000 | Required by most lenders as a condition of the loan |
| Loan application/establishment fee | A$0–A$800 | Many competitive lenders now have no application fee |
| Total buying costs (estimate) | A$89,200–A$95,100 | In addition to your deposit |
Variable vs Fixed Rate — Which Makes Sense Now?
With two RBA rate hikes already in 2026 and markets uncertain about whether further increases are coming, the variable vs fixed decision is particularly important. Variable rate advantages: typically lower than fixed at most major lenders currently, full offset account access, extra repayments allowed without penalty, and you benefit immediately if rates fall. Fixed rate advantages: certainty over repayments for 1–5 years, protection against further rate rises, and easier household budgeting.
Many Australian borrowers opt for a split loan — fixing a portion (say 50%) for certainty while keeping the remainder variable for flexibility and offset account access. This is not a compromise — for many borrowers it's genuinely the optimal structure given rate uncertainty.
💡 Use an offset account — it's one of the most powerful features of an Australian mortgage. Money sitting in your offset account reduces the loan balance on which interest is calculated. A$50,000 in an offset account against a A$500,000 loan means you only pay interest on A$450,000. The interest saving is equivalent to earning your mortgage rate on those savings, tax-free. On a 5.65% loan, that's effectively a guaranteed 5.65% return on your offset funds.
Should I Use a Mortgage Broker?
For most Australian borrowers, yes. A good mortgage broker has access to 30–40 lenders, runs your application once and presents multiple offers, is typically paid by the lender (not you), and can often negotiate rates you wouldn't get by approaching a bank directly. ASIC-licensed brokers have a legal duty to act in your best interest. The lender that advertises the lowest rate is not always the right choice — consider features (offset, redraw, extra repayments), fees, and serviceability assessment criteria, which vary by lender.

At a competitive variable rate of 5.15% over 30 years, A$1,500,000 repayments are approximately A$8,190/month. At the big bank average of 5.75%, repayments rise to approximately A$8,754/month. At the APRA serviceability buffer rate of 8.65% (your actual rate + 3%), which lenders use to assess affordability, the assessed repayment is A$11,694/month.

As of May 2026, the RBA cash rate is 4.10%, following two increases of 0.25% each in February and March 2026. This reversed the three cuts delivered in 2025. NAB announced it would increase variable home loan rates by 0.25% effective 15 May 2026. Markets are pricing in the possibility of one further increase later in 2026, though the RBA's May 2026 meeting will be watched closely for guidance.
The minimum deposit for most standard home loans is 5% with Lenders Mortgage Insurance (LMI). To avoid LMI, you need a 20% deposit (80% LVR). First home buyers may access the First Home Guarantee with 5% deposit and avoid LMI on eligible properties. Some lenders accept 10% deposits with LMI. The 20% threshold is significant — below it, LMI can add A$10,000–A$50,000+ to your costs depending on the loan amount.
Lenders apply a serviceability buffer of 3% above your actual rate (APRA requirement). At 5.65% variable, the assessment rate is 8.65%. Monthly repayments at 8.65% on A$1,500,000 over 30 years are approximately A$11,694. Most lenders require that total debt repayments don't exceed 30–35% of gross income. This implies a minimum gross income of approximately A$438,507/year, though individual lender policies vary and other debts affect this calculation.
With two RBA rate hikes already in 2026, some borrowers are considering fixing to protect against further increases. Fixed rates at major lenders are currently 5.8–6.4% for 2-year terms — often higher than variable rates. Fixing locks you in and removes offset account access for most fixed rate products. If rates fall further, you miss the benefit. The split loan approach — fixing a portion while keeping the rest variable — is popular precisely because it hedges against both scenarios.
LMI is insurance the borrower pays (but which protects the lender) when the LVR exceeds 80%. For A$1,500,000 at 90% LVR (meaning the property is worth approximately A$1,666,666 and you have a 10% deposit), LMI can cost A$22,500–A$37,500 depending on the lender. LMI can be added to the loan amount (capitalised) which reduces the upfront cash needed but increases total interest paid. Saving a 20% deposit avoids this cost entirely.
