If you’re dreaming about buying a home in Toowoomba, Brisbane, or anywhere across Australia, one question probably keeps popping up: “How much can I actually borrow?”
That’s where borrowing capacity or borrowing power comes in.
Simply put, it’s the maximum amount a lender is willing to loan you for a home. But it’s more than just a number—it’s a reflection of your financial health, lifestyle, and long-term goals. Understanding it can make your property journey smoother, smarter, and far less stressful.
Why Borrowing Capacity Matters
Your borrowing capacity sets the stage for every decision in your property journey. It determines:
- What you can comfortably afford to buy
- How much deposit you need
- Whether you qualify for certain loans or avoid Lenders Mortgage Insurance
- How comfortable your mortgage repayments will be, now and in the future
Knowing your borrowing power before you start house hunting prevents wasted time, dashed hopes, and stressful situations where you have to back out of a purchase. Imagine falling in love with a property only to find your loan doesn’t cover it. Avoid that nightmare by understanding your financial ceiling upfront.
What Determines Your Borrowing Power?
Lenders don’t just glance at your salary and say yes. They examine your entire financial picture—income, debts, expenses, and lifestyle. Here’s what they typically consider:
- Income: This includes your salary, bonuses, rental income, investment returns, and any other regular sources of money.
- Debts and financial commitments: Credit card limits (yes, even if unused), personal loans, car loans, HECS-HELP debt, and existing mortgages.
- Living expenses: Groceries, utilities, school fees, entertainment, and other regular costs. Lenders often use a Household Expenditure Measure, which can be higher than what you personally track.
- Interest rate buffers: Even if today’s rate is 6-6.5%, lenders often assess your repayments at 2–3% higher to ensure you can handle potential rises.
- Employment stability: Full-time permanent work often gets more weight than casual, contract, or self-employed income, but non-traditional earners can still achieve strong results with the right documentation.
Understanding these factors helps you see why your borrowing capacity might be lower than expected—and why lenders err on the side of caution.
Practical Borrowing Capacity Example
To make this tangible, consider a homebuyer in Toowoomba earning $90,000 annually with a car loan and a credit card.
| Income & Commitments | Amount |
| Annual salary | $90,000 |
| Monthly gross income | $7,500 |
| Car loan repayment | $300/month |
| Credit card limit ($10,000) | $300/month (3% of limit) |
| Estimated living expenses | $2,200/month |
After accounting for tax, existing commitments, living expenses, and applying a lender’s assessment rate (around 8.5-9%), this borrower’s potential loan amount might be:
$380,000 to $430,000.
However, this assumes no HECS-HELP debt. Also, actual capacity varies between lenders, with some offering $50,000+ more or less.

How Lenders Calculate Borrowing Capacity
Most lenders follow similar principles, but their assessments can differ. A typical calculation includes:
- Starting with gross income
- Subtracting living expenses and existing debt repayments
- Adding an interest rate buffer
- Calculating monthly repayment capacity
- Converting this into a maximum loan amount
Different lenders weigh these factors differently. One might approve $650,000; another might cap at $550,000, even with identical financial information. That’s why working with experienced mortgage brokers like ours is valuable—they know which lenders match your profile best.
Using Borrowing Capacity Calculators
Online calculators are a popular first step, but they’re only rough guides. They can’t capture:
- Non-traditional income streams
- Regional property nuances
- Complex debt structures
Tips for using calculators effectively:
- Be honest about your expenses
- Try multiple calculators from different lenders
- Treat results as estimates, not guarantees
A mortgage broker provides the most accurate picture, combining multiple lenders’ criteria and insider knowledge unavailable in generic tools.
Ways to Increase Your Borrowing Capacity
Your borrowing power isn’t set in stone. You can improve it with strategic moves:
- Reduce or remove credit card limits: Lenders consider the limit, not the balance. High unused limits can reduce borrowing capacity unnecessarily.
- Consolidate debts carefully: Fewer monthly obligations improve calculations, though interest costs must be considered.
- Increase income: Through salary negotiations, side work, or including a partner’s income.
- Maintain clear financial records: Especially for self-employed borrowers; two years of well-documented income shows stability.
- Trim discretionary spending before applying: Bank statements show habits; excessive cash withdrawals, gambling, or entertainment can raise lender concerns.
- Check your credit report: Correct errors and avoid recent multiple applications to strengthen your borrowing power.
These steps not only increase the number lenders see but also signal financial discipline, which matters just as much.
Borrowing Capacity and Toowoomba Buyers
Toowoomba offers a unique property landscape. Compared to Brisbane, homes are more affordable, so your borrowing power stretches further. Lifestyle migration, infrastructure investment, and strong rental demand have strengthened the market.
Regional nuances to consider:
- Some lenders apply slightly different serviceability criteria for regional properties
- Investment property borrowing is assessed differently; rental income is discounted at 70-80% for vacancy and maintenance
- Our expert Toowoomba Mortgage Broker can help identify which lenders favour regional properties
Understanding your borrowing capacity in this market allows you to act decisively when the right property appears.
Common Borrowing Capacity Myths
- Higher income equals higher borrowing: Not always. Higher income can increase living expenses, and lenders become cautious with large loans.
- One bank’s rejection means all will reject: Lender criteria vary widely; a no for one could be a yes for another.
- Calculators include deposits: They don’t. Your total property budget is borrowing capacity plus deposit plus transaction costs.
Dispelling these myths keeps your expectations realistic and your property journey stress-free.
Strategic Borrowing: Don’t Max Out
Just because a lender approves a maximum loan doesn’t mean you should borrow it. Life throws curveballs—rate rises, career changes, and family expenses can impact repayments. You may borrow below your maximum to maintain flexibility and comfort.
Next Steps for Homebuyers

- Define a realistic property budget considering deposit and borrowing capacity
- Compare lenders to see how their criteria affect your borrowing power
- Consult a mortgage broker to navigate multiple lenders, optimise your application, and negotiate favourable terms
- Regularly review your capacity as income grows, debts reduce, or circumstances change
