ESTIMATE
Illustrative estimates as of 3 November 2026, not financial advice or a loan offer. Base rate 6.49% = Canstar’s average owner-occupier variable rate (principal & interest) after the September 2026 RBA rise, before lenders pass on the 3 November rise (about 6.74% once passed on in full); RBA cash rate 4.85%, next decision 2:30pm AEDT on Tuesday 8 December 2026. Your lender’s rate, fees and assessment will differ.
A $1,500,000 home loan costs about $9,471 per month (30 years) or $10,119 (25 years) at the 6.49% average owner-occupier variable rate. The bank, however, checks that you could pay $12,602 a month — the repayment at 9.49% once APRA’s 3-point serviceability buffer is added.

Plug in your own price and deposit
The live mortgage repayment calculator handles any property price, deposit, rate and term, monthly or fortnightly.
The Reserve Bank has lifted the cash rate five times in 2026, from 3.60% to 4.85%, most recently on 3 November. The big four passed the September rise on in full from 9 October, and Canstar estimated the average owner-occupier variable rate at 6.49% once they caught up; if the November rise is passed on in full, that average becomes about 6.74%. Sharper lenders still advertise from 5.89% and the average across every advertised product is higher at 6.75%. On $1,500,000, each 0.25-point step moves the 30-year repayment by about $248 a month, and the gap between the cheapest and the average rate is worth $584 a month.
A large home loan. At $1.5m you are firmly in jumbo territory. Most buyers need two incomes, a 20%+ deposit ($375,000 on a $1,875,000 price) and a clean credit file. LMI premium tables from insurers typically stop at $1 million, so above that many lenders cap the loan-to-value ratio or price LMI case by case. A 0.25-point rate rise alone adds $248 a month.
25 vs 30 years: total interest on $1,500,000
The term is a trade-off between monthly comfort and lifetime cost. At 6.49% a 30-year term costs $648 a month less than 25 years, but total interest climbs from $1,535,621 to $1,909,617 — an extra $373,996. A 20-year term would cost $1,056 a month more than 25 years and save another $353,677.

Monthly vs fortnightly vs weekly repayments on $1,500,000
Fortnightly pay cycles make fortnightly repayments popular in Australia. If you choose a true fortnightly repayment the lender works out $4,369 — the 30-year loan simply split into 26 smaller payments a year — and it saves only a little interest. The trick is paying half the monthly amount, $4,736, every fortnight: 26 halves equal 13 monthly payments a year, so the loan is gone in about 24 years 2 months instead of 30 years and you save about $439,163 of interest. Paying a quarter of the monthly amount ($2,368) weekly works almost the same: about 24 years 1 month and $441,014 saved.

Principal & interest vs interest-only on $1.5m
Interest-only (IO) periods of up to five years are mainly used by investors and by owner-occupiers managing a temporary squeeze, such as parental leave. At 6.49% the IO repayment on $1,500,000 is $8,113 a month, $1,359 less than principal and interest. The catch: after five years you still owe all $1,500,000, and the loan has only 25 years left to clear it, so the repayment jumps to $10,119 — $2,006 a month more than during the IO period, and $648 more than if you had paid P&I from day one. Over the life of the loan you pay about $112,754 extra interest, before any IO rate premium (RBA data show investor interest-only loans priced roughly 0.2 points above P&I in August 2026).
How an offset account changes a $1.5m loan
An offset account is a transaction account linked to the loan: the balance is subtracted before interest is charged, so $50,000 of savings against $1,500,000 means you pay interest on $1,450,000 — while the repayment stays at $9,471, and the extra goes straight off the principal. Because the saving equals your loan rate and is not taxed, it is worth more than a savings account paying 6.49% before tax to anyone who pays income tax.

Balance held constant for the whole loan; in practice it rises and falls with your pay cycle. Offset loans often carry a package fee or a slightly higher rate — see offset accounts explained.
Deposit, LMI and the 5% Deposit Scheme
With a 20% deposit — $375,000 on a $1,875,000 home — no lenders mortgage insurance applies. Borrow more than 80% of the value and the lender passes on an LMI premium, which is usually added to the loan. The table uses one lender’s indicative premium table (full-doc, May 2026); your quote will differ, and most states also charge stamp duty on the premium.

5% Deposit Scheme: a 5% deposit would mean a $1,578,947 purchase, above every First Home Guarantee price cap (the highest is $1.5 million), so the scheme cannot be used here. See LMI explained and the First Home Guarantee 2026 rules.
What income do you need for a $1,500,000 mortgage?
Australian lenders do not use a fixed income multiple. They test whether you could still pay at the assessment rate — the loan rate plus APRA’s 3-point serviceability buffer, 9.49% here — after your declared living expenses (or the Household Expenditure Measure, if higher), other debts and credit-card limits. At 9.49% the 30-year repayment on $1,500,000 would be $12,602 a month, $3,131 more than you would actually pay today.
30% rule of thumb: keeping the real repayment ($9,471) under 30% of gross pay needs about $378,800 a year — a single earner on that salary takes home about $19,577 a month in 2026-27, so the repayment is 48% of take-home. A couple on $189,400 each takes home $22,413 together (42%).
APRA debt-to-income limit: since 1 February 2026 banks may write only 20% of new owner-occupier loans at a DTI of 6 or more. $1,500,000 ÷ 6 = $250,000 of gross income before this loan alone becomes “high DTI”.
Check LMI before you rush. At 90% LVR the indicative LMI premium on this loan is quoted case by case. Saving to 85% LVR, using a guarantor or qualifying for the 5% Deposit Scheme can remove or cut that cost.
Compare comparison rates. Australian lenders must show a comparison rate (based on a $150,000 loan over 25 years) that folds in most fees. Use it to compare, but remember it understates fees on large loans less than on small ones.
Haggle with your existing lender. Lenders often price new customers below existing ones. On $1.5m, getting from 6.49% to 5.99% saves about $488 a month — ask for a rate review before refinancing, then compare with the 5.89% lowest variable rate on the market.
Pay fortnightly, not “fortnightly equivalent”. Paying half the monthly amount every fortnight makes 26 half-payments a year — one extra month annually. On this loan that clears it 5 years 10 months sooner and saves about $439,163 interest at 6.49%.
Park savings in an offset. Every dollar in an offset account saves interest at your loan rate, tax-free. $50,000 sitting in an offset against $1.5m saves about $268,724 of interest over the loan and finishes it 2 years 4 months early.
FAQ
What are the repayments on a $1,500,000 home loan?
At the 6.49% average owner-occupier variable rate (Canstar, after the September 2026 RBA rise, before lenders pass on the November rise) a $1,500,000 principal-and-interest loan costs about $9,471 a month over 30 years or $10,119 over 25 years. Fortnightly over 30 years it is $4,369; weekly $2,184.
How much income do I need for a $1.5m home loan?
As a rule of thumb, keeping the $9,471 monthly repayment to 30% of gross income needs about $378,800 a year. Banks assess at 9.49% (the rate plus APRA’s 3-point buffer), where the repayment would be $12,602 a month, and subtract your living costs and other debts. To stay below a debt-to-income ratio of 6 you would need at least $250,000 of gross income if this is your only debt.
How much interest will I pay on $1,500,000?
About $1,909,617 over 30 years or $1,535,621 over 25 years at 6.49%, if the rate never changed. Paying half the monthly repayment every fortnight cuts the 30-year interest by about $439,163.
What are interest-only repayments on $1,500,000?
$8,113 a month at 6.49%. If you take 5 years interest-only on a 30-year loan, repayments then jump to $10,119 for the remaining 25 years, and total interest rises to about $2,022,371 versus $1,909,617 on principal and interest. Lenders usually charge a higher rate for interest-only.
How much is LMI on a $1.5m loan?
Indicative LMI tables usually stop at $1 million, so lenders quote LMI on a $1,500,000 loan case by case and may cap the loan-to-value ratio. With a 20% deposit ($375,000) no LMI applies.
Can I use the 5% Deposit Scheme for a $1.5m loan?
A $1,500,000 loan with a 5% deposit means a $1,578,947 price, above every First Home Guarantee cap (the highest is $1.5 million in Sydney and listed NSW regional centres), so the scheme would not apply.
RBA cash rate target 4.85%: raised 0.25 points on 3 November 2026, effective 4 November (the Monetary Policy Board voted 6–3). It was the fifth rise of 2026, after February, March, May and September. The Board’s next decision is at 2:30pm AEDT on Tuesday 8 December 2026.
Average owner-occupier variable rate (P&I) 6.49%: Canstar estimate once the September rise was passed on (29 September 2026), in line with RBA Table F6 — new owner-occupier variable loans averaged 6.23% in August 2026, before the rise. Canstar’s average advertised rate across its whole database was 6.75% (13 October 2026) and the lowest variable rate was 5.89% (20 October 2026). As of 3 November no big-four bank had announced how it would pass on the November rise; passed on in full, it lifts the average to about 6.74%.
Fixed rates: big-four 1–2 year fixed rates ranged from 6.49% (ANZ) to 6.81% (NAB 2-year) in October 2026; the lowest fixed rate on Canstar was 5.79% (1-year).
APRA serviceability buffer: 3 percentage points above the loan rate (kept unchanged in APRA’s May 2026 review). From 1 February 2026 no more than 20% of a bank’s new owner-occupier lending (and separately investor lending) may be at a debt-to-income ratio of 6 or more.
LMI: indicative full-doc premiums from one lender’s table published by Home Loan Experts (updated 18 May 2026); insurers price individually and state stamp duty on the premium may apply (none in NSW).
5% Deposit Scheme (First Home Guarantee): Housing Australia rules from 1 October 2025 — unlimited places, no income caps; Darwin cap raised to $750,000 from 1 July 2026.
Repayments use standard amortisation (monthly, fortnightly or weekly compounding to match the payment) with the rate held constant for the whole term; real loans calculate interest daily and rates change.
