One of the first questions most buyers ask is simple:
How much can I borrow for a home loan?
Many also ask, “how much home loan can I get?” If you search “borrowing power Australia” online, you’ll see plenty of tools that promise quick estimates.
It sounds like it should have a simple answer. But in practice, borrowing capacity can vary significantly from one lender to another. Two lenders can look at the same income, the same expenses and the same deposit, yet reach different conclusions about how much they are prepared to lend.
That is why a borrowing power calculator is useful as a starting point, but not the final answer. You can also try a mortgage borrowing calculator or a borrowing capacity calculator to compare different scenarios, but treat the figures as guides only.
A calculator can help you estimate your position before you apply, but the real result depends on how a lender assesses your full situation, which a home loan borrowing power calculator cannot fully capture.
What lenders look at when calculating borrowing power (home loan borrowing capacity)
When assessing how much you may be able to borrow, lenders usually look at:
- income;
- living expenses;
- dependants;
- existing debts;
- credit card limits;
- deposit or equity;
- loan purpose;
- credit history;
- property type;
- repayment type;
- loan term;
- lender policy.
Your income matters, but it is not the only factor. A borrower with a high income and high commitments may be able to borrow less than someone with a lower income and fewer debts.
This is why “how much can I borrow?” is really a serviceability question. The lender wants to know whether the proposed loan appears affordable after allowing for your existing commitments and a buffer for potential interest rate changes.
Why borrowing power varies between lenders
Borrowing capacity is not fixed across the market.
Each lender applies its own credit policy, assessment rate, expense assumptions and treatment of income. Some lenders may be more flexible with overtime, bonuses, commissions, rental income or self-employed income. Others may take a more conservative approach.
Credit card limits are another common example. Even if your credit card balance is low or paid off each month, a lender may still assess the full limit as a potential debt commitment. Reducing unused limits can sometimes improve borrowing capacity.
This is a key reason your home loan borrowing capacity can look different from one bank to the next. A home loan borrowing power calculator can give you a useful guide, but it cannot fully replicate every lender’s policy.
Deposit and equity also matter
Borrowing power is not only about income and expenses. Your deposit or equity position also matters.
If you are buying a property, lenders will consider how much you are contributing and whether Lenders Mortgage Insurance may apply. First home buyers also need to allow for purchase costs, which may include stamp duty, legal costs, inspections, application fees and moving costs.
If you are refinancing, lenders will look at your current loan balance, estimated property value and available equity. Your refinance borrowing power may also depend on the purpose of the refinance, especially if you want to access additional funds.
Should you borrow the maximum available?
Not always.
A lender may approve a certain amount, but that does not mean it is the right amount for your lifestyle or plans. Your personal comfort level matters.
Before borrowing near your maximum capacity, consider:
- what repayments would look like if rates changed;
- whether your income is stable;
- future family or lifestyle plans;
- upcoming expenses;
- job or business risk;
- whether you want flexibility for investment or renovations;
- how much cash buffer you want to keep.
Good lending advice should help you understand not only what may be possible, but what may be sensible.
What to do next
A borrowing capacity calculator can help you get a starting estimate. The next step is to check whether the result is realistic for your situation. You can also compare results from a mortgage borrowing calculator to see how different assumptions affect estimates.
A broker can compare lender policies, identify potential issues and help you understand whether you are ready to apply now or should improve your position first. A mortgage broker borrowing capacity assessment can highlight which lenders may suit your goals and how to strengthen your application.

Q&A
Question: Is there a simple answer to “How much can I borrow for a home loan?”
Short answer: Not really. Online borrowing power calculators are a useful starting point, but they can’t capture your full situation or every lender’s policy. The amount you can borrow depends on how a specific lender assesses your income, expenses, debts, deposit/equity, and other details, so real outcomes can differ from the calculator estimate.
Question: Why might two lenders give me different borrowing amounts?
Short answer: Each lender applies its own credit policy and assumptions. Differences commonly include:
- Assessment rates and buffers used for interest rate changes
- How they treat overtime, bonuses, commissions, rental or self‑employed income
- Assumptions for living expenses and dependants
- How they count existing commitments (for example, assessing your full credit card limit even if you pay it off monthly) Because of these variations, the same profile can produce different borrowing capacities across lenders.
Question: What do lenders look at when calculating borrowing capacity?
Short answer: Typical factors include:
- Income
- Living expenses
- Dependants
- Existing debts
- Credit card limits
- Deposit or equity
- Loan purpose
- Credit history
- Property type
- Repayment type
- Loan term
- Lender policy A high income doesn’t guarantee a higher loan if you also have high commitments—serviceability (affordability after all commitments and buffers) is what counts.
Question: How do my deposit or equity and upfront costs affect what I can borrow?
Short answer: Deposit and equity influence both how much you can borrow and on what terms.
- Buying: Lenders look at your contribution and whether Lenders Mortgage Insurance may apply. First home buyers should also allow for purchase costs like stamp duty, legal fees, inspections, application fees, and moving costs.
- Refinancing: Lenders consider your current loan balance, estimated property value, and available equity. Your goals for refinancing (e.g., accessing extra funds) can also affect how much a lender is comfortable approving.
Question: Should I borrow the maximum available, and what should I do next?
Short answer: Not necessarily. An approval amount isn’t automatically the right amount for your lifestyle or risk tolerance. Before borrowing near your limit, consider:
- How repayments would look if rates rise
- Income stability and job/business risks
- Family or lifestyle plans and upcoming expenses
- Desire for flexibility (e.g., renovations, investments)
- The cash buffer you want to keep Next steps: Use a borrowing capacity calculator as a guide, then sense‑check the result. A broker can compare lender policies, flag issues, and assess whether you’re ready to apply or should strengthen your position first. Evolve Lending & Finance can help you understand what sits behind the number and identify the lending path that best fits your plans.
