Combined income serviceability calculation for $80,000
Australian lenders assess a couple's borrowing capacity by combining both incomes and applying the Household Expenditure Measure (HEM) for a couple household. Here's how lenders calculate your maximum loan on a combined $80,000 income, assuming a roughly 55/45 income split ($44,000 and $36,000):
| Calculation step | Borrower 1 ($44,000) | Borrower 2 ($36,000) | Combined |
|---|---|---|---|
| Gross monthly income | $3,667 | $3,000 | $6,667 |
| Income tax + Medicare | −$451 | −$284 | −$735 |
| Net monthly take-home | $3,216 | $2,716 | $5,933 |
| HEM living expenses (couple) | Shared household benchmark | −$3,600 | |
| Uncommitted Monthly Income (UMI) | $2,333 | ||
| APRA assessment rate | 9.14% (6.14% variable + mandatory 3% buffer) | ||
| Maximum home loan (30yr) | $290,000 — monthly repayment $1,765 | ||
Note: HEM for a couple with no dependants in a capital city is approximately $3,600 per month. If you have children, lenders add approximately $800–$1,200 per child per month, which reduces borrowing capacity. If your actual declared expenses exceed HEM, lenders use your actual expenses — whichever is higher.
How lenders assess dual income applications
Joint home loan applications are assessed differently to single-income applications in several important ways:
- Both incomes are combined — lenders add both gross incomes together and calculate net income after tax for each borrower separately before combining.
- HEM is assessed at couple/household level — the HEM benchmark for two people is lower than two individual HEM figures combined, which is a significant advantage for couple borrowers.
- Both borrowers are jointly and severally liable — if one borrower cannot service the loan, the other is fully responsible for the entire repayment.
- Part-time or casual income — lenders may shade casual income by 20% and may require 12 months employment history. If one partner is on parental leave, lenders typically assess only the returning-to-work income.
- Parental leave — most lenders require evidence of returning to work and use pre-leave income. Westpac, CBA, and ANZ are generally more flexible here.
- Bonus and overtime — typically accepted at 50–80% of the most recent 2-year average if it appears consistently on payslips.
Repayment scenarios for $290,000 loan
Here's what monthly repayments look like on a $290,000 home loan across different interest rate scenarios and loan terms. The APRA stress test ensures you can handle rates 3% above current levels.
| Scenario | Interest rate | Monthly repayment | Annual repayment |
|---|---|---|---|
| Best variable rate (Virgin Money) | 5.19% | $1,591 | $19,092 |
| Competitive non-bank rate | 5.44% | $1,636 | $19,632 |
| Average variable (current) | 6.14% | $1,765 | $21,180 |
| Big 4 average | 6.19% | $1,774 | $21,288 |
| APRA stress test rate | 9.14% | $2,363 | $28,356 |
APRA stress test: Your lender must confirm you can afford repayments of $2,363/month at the 9.14% assessment rate. Your $80,000 combined income comfortably passes this test at the $290,000 loan size above.
Deposit and LMI on a $290,000 loan
To buy a $350,000 property with a $290,000 loan, here are your deposit options:
- 20% deposit ($60,000) — avoids Lenders Mortgage Insurance entirely. Ideal if you have savings or equity from a previous property.
- 10% deposit ($35,000) — LMI applies. Estimated LMI cost: $5,000–$8,000 (can be capitalised into the loan).
- 5% deposit with First Home Guarantee — if both borrowers are first home buyers and meet income caps ($200,000 combined), the government guarantees the remaining 15%, avoiding LMI entirely.
How to increase couple borrowing capacity
- Reduce or close credit card limits — lenders assess 3.8% of your total credit card limit as a monthly liability, regardless of balance. A $20,000 card limit reduces borrowing power by approximately $50,000–$60,000.
- Declare all income streams — rental income (at 80%), side business income (if 2+ years ABN history), overtime and bonuses can all be included. Many couples underestimate their combined assessable income.
- Pay down HECS-HELP debts — each partner's HECS repayment is treated as a monthly liability. Combined HECS of $80,000 can reduce couple borrowing power by $120,000–$160,000.
- Time any parental leave applications carefully — applying while one partner is on parental leave reduces assessable income significantly. If possible, apply after returning to work.
- Choose a lender that suits your income split — some lenders are more generous with high-split dual incomes (e.g., one partner on $120k, one on $30k). A broker can identify the best fit.
- Get a pre-approval — a formal pre-approval locks in your borrowing power and strengthens your position when making offers at auction.
Frequently asked questions
How much can a couple borrow on $80,000 combined income?
On a combined income of $80,000, a couple can typically borrow approximately $290,000. This assumes average HEM expenses of $3,600/month, no existing debts, and is calculated using the APRA 3% serviceability buffer at a 9.14% assessment rate over 30 years. The typical lender range is $250,000 to $330,000.
Is borrowing power higher for couples than singles with the same income?
Yes, in most cases. The key advantage is HEM — a couple's HEM benchmark ($3,600/month) is significantly lower than two individual HEM figures combined (which would total approximately $5,400/month). This means more of the combined income is counted as Uncommitted Monthly Income (UMI) available to service the mortgage, resulting in higher borrowing capacity per dollar of income.
Does it matter if the income split is unequal?
The combined total is what matters most, but a very unequal split can sometimes affect the outcome. This is because income tax is progressive — one high earner pays more tax than two lower earners with the same total income. For example, a $200k/$0 split pays more total tax than a $100k/$100k split, resulting in slightly lower borrowing power on the same combined income. The income split assumed on this page is approximately 55/45.
How do children affect couple borrowing power?
Significantly. Lenders add approximately $800–$1,200 per dependent child per month to the HEM benchmark. A couple with two children on $80,000 combined would see borrowing power reduced by approximately $30,000–$50,000 compared to a couple with no dependants. The exact impact varies by lender and income level.
Can one partner's income be excluded from the application?
Yes. If one partner has poor credit history or significant debts, it is sometimes better to apply as a single borrower using only one income. However, the single borrower would then qualify for a much smaller loan. A mortgage broker can model both scenarios and advise which approach gives the better outcome for your specific situation.
