How much can you
borrow?
Estimate your home loan borrowing capacity in Australia — using your real income, expenses, debts, and credit card limits, assessed the way lenders do with APRA's 3.0 percentage point buffer. Free, no signup.
Quick answer: A single applicant with $95,000 gross income, $2,500/month in assessed expenses could borrow an estimated $445,758 over 30 years. That's assessed at 9.2% (your 6.2% rate plus APRA's 3.0pp buffer) against a monthly surplus of $3,651. At the actual 6.2% rate you'd repay about $2,730/month. This is an indicative estimate, not a loan offer, pre-approval, or financial advice.

Borrowing capacity in Australia is a serviceability test, not a multiple of your salary. The calculator starts with your gross income, converts it to after-tax income using the ATO 2025-26 brackets (income tax, the Medicare levy, the low-income tax offset, and compulsory HECS repayments if you have a study debt), and divides by twelve to get your net monthly income.
From that it subtracts your assessed living expenses, your existing loan repayments, and a margin against your credit card limits (about 3.8% of the limit per month, whether or not you carry a balance). What's left is your monthly surplus — the amount available to service a new mortgage repayment.
The APRA buffer does the heavy lifting
The surplus isn't assessed at your actual interest rate. Since 2021, APRA has required lenders to test serviceability at the product rate plus a 3.0 percentage point buffer — so a 6.2% loan is assessed at 9.2%. The maximum loan is then the present value of your surplus repaid over the loan term at that buffered rate. This is why your borrowing capacity is meaningfully lower than what your income alone might suggest, and why a small change in expenses or card limits moves the number so much.
What this calculator doesn't model
This is a serviceability estimate, not the deposit side. It doesn't check your loan-to-value ratio, deposit, or Lenders Mortgage Insurance — your real purchase price is capped by whichever is lower, capacity or deposit. It uses the expenses you enter rather than running a lender's exact HEM table, and it doesn't shade overtime, bonus, or rental income the way individual lenders do. Treat the result as an indicative mid-range figure, not a loan offer, pre-approval, or financial advice.
How to use this calculator
- Choose whether you're applying as a single applicant or jointly. For a joint application, enter both gross (before-tax) annual incomes — lenders assess your combined serviceability.
- Tick the HECS-HELP box for anyone with a study debt. Compulsory HECS repayments are withheld from pay above ~$54,435, which lowers the net income available to service a loan.
- Enter your monthly living expenses honestly. Lenders apply the Household Expenditure Measure (HEM) as a floor, so understating spending won't lift your real capacity — it just makes this estimate less accurate.
- Add your existing monthly debt repayments (car loans, personal loans, other mortgages) and your total credit card limits. Lenders assess about 3.8% of card limits per month as a commitment, even on cards paid off in full.
- Set the interest rate for the loan you're considering — early-2026 owner-occupier variable rates sit around 6.0% to 6.5%. The calculator automatically assesses you at this rate plus APRA's 3.0 percentage point buffer.
- Read your estimated maximum borrowing capacity, the monthly repayment you'd actually pay at the product rate, and your assessed monthly surplus. Then model the deposit side with the LMI and Stamp Duty calculators.
❓ Frequently Asked Questions
How much can I borrow for a home loan in Australia?
Your borrowing capacity is set by serviceability, not just income. Lenders take your after-tax income, subtract your living expenses, existing debt repayments, and a margin against your credit card limits, then check whether the surplus can cover the new loan repayment assessed at your interest rate plus APRA's 3.0 percentage point buffer. As a rough guide in early 2026, a single applicant on $95,000 with no debts can typically borrow around $440,000 to $480,000, and a couple on a combined $160,000 around $800,000 to $900,000 — but the exact figure swings heavily with your expenses, dependents, HECS debt, and credit card limits. This calculator estimates it from your real numbers.
What is the APRA serviceability buffer?
Since October 2021, APRA has required Australian lenders to assess every new mortgage at an interest rate at least 3.0 percentage points above the actual product rate. So if your loan rate is 6.2%, the bank tests whether you could still afford the repayments at 9.2%. The buffer exists to make sure borrowers can cope if rates rise. It is the single biggest reason your borrowing capacity is lower than a simple repayment calculation suggests — this tool applies the full 3.0pp buffer to the assessment.
How do living expenses affect my borrowing capacity?
Heavily. Lenders don't just take your word for your spending — they apply the Household Expenditure Measure (HEM), a benchmark of minimum reasonable living costs that scales with your income, location, and number of dependents. If your declared expenses are below the HEM floor for your household, the lender uses the higher HEM figure. Every $500/month of assessed expenses reduces a 30-year borrowing capacity by roughly $60,000 to $70,000. Cutting discretionary spending in the months before you apply genuinely lifts how much you can borrow.
Do credit card limits reduce how much I can borrow?
Yes — and it's the limit, not the balance, that counts. Lenders assess roughly 3.8% of your total credit card limits as a monthly commitment, even if you pay the card off in full each month and owe nothing. A $20,000 combined card limit is assessed as about $760/month of commitment, which can cut your borrowing capacity by $80,000 or more. Reducing or cancelling unused card limits before you apply is one of the fastest ways to lift your capacity.
How does HECS-HELP debt affect borrowing capacity?
A HECS-HELP debt reduces your net (after-tax) income because compulsory repayments are withheld from your pay once you earn above the threshold (around $54,435 for 2025-26), at 1% to 10% of income depending on how much you earn. Lenders treat that repayment as a reduction in serviceable income. On a $90,000 salary, an outstanding HECS debt can lower your borrowing capacity by $30,000 to $50,000. Note: from 1 June 2025 the government changed how some lenders treat HECS for serviceability — many now disregard it if the debt will be cleared within 12 months. This calculator includes the HECS repayment in net income when you tick the box.
Is borrowing capacity the same as a pre-approval?
No. Borrowing capacity is an estimate of the maximum a lender might lend based on your income and commitments. A pre-approval (conditional approval) is a lender's formal indication, after reviewing your documents and credit file, that they're willing to lend up to a stated amount subject to conditions — but it's still not a guarantee, and it doesn't account for the property valuation. This calculator gives you a capacity estimate to plan with; it is not a loan offer, pre-approval, or financial advice.
Does this include my deposit, LVR, or LMI?
No — this tool estimates serviceability (how much repayment your income can support), not the deposit side. Your actual purchase price is the lower of your borrowing capacity and what your deposit allows at the lender's maximum loan-to-value ratio (LVR). If you borrow more than 80% of the property value, you'll usually pay Lenders Mortgage Insurance (LMI). Use the Richify LMI Calculator and Stamp Duty Calculator to model the deposit and upfront-cost side alongside this capacity estimate.
Why do different banks give me different borrowing limits?
Because each lender uses its own HEM benchmark, its own assessment of overtime and bonus income (many shade casual or variable income to 80%), its own treatment of HECS and childcare, and its own floor rate. Two lenders can differ by $100,000+ on the same applicant. The figure here uses standard, conservative assumptions (full HEM-style expenses you enter, the 3.0pp APRA buffer, 3.8% of card limits) to give a realistic mid-range estimate — a broker can tell you which specific lenders assess your situation most generously.
Is Richify available in Australia, and what does it cost?
