Comprehensive Guide to Calculating Your Home Loan Borrowing Power
Understanding your home loan borrowing power is crucial when planning to purchase property. This comprehensive guide will explain how lenders calculate your borrowing capacity, what factors influence it, and how you can improve your chances of securing a favorable home loan.
What is Borrowing Power?
Borrowing power, also known as borrowing capacity, refers to the maximum amount a lender is willing to loan you based on your financial situation. It’s determined by assessing your income, expenses, existing debts, and other financial commitments against the lender’s risk criteria.
Key Factors Affecting Borrowing Power
- Income: Your regular salary, bonuses, rental income, and other revenue streams
- Expenses: Living costs, existing loan repayments, and financial commitments
- Interest Rates: Current market rates and potential rate increases
- Loan Term: The length of time over which you’ll repay the loan
- Credit History: Your credit score and repayment history
Why Borrowing Power Matters
- Helps you understand your budget for property purchases
- Prevents over-committing to unaffordable loans
- Allows for better financial planning and goal setting
- Increases your negotiating power with lenders
- Helps you compare different loan products effectively
How Lenders Calculate Borrowing Power
Most lenders use a combination of the following methods to determine your borrowing capacity:
1. Debt-to-Income Ratio (DTI)
This is the percentage of your gross monthly income that goes toward paying debts. Most lenders prefer a DTI below 43%, though some may accept up to 50% for well-qualified borrowers.
Formula: (Total Monthly Debt Payments / Gross Monthly Income) × 100
2. Loan-to-Income Ratio (LTI)
This measures the size of your loan compared to your income. A lower LTI generally indicates lower risk to the lender.
Formula: (Loan Amount / Annual Income) × 100
3. Serviceability Assessment
Lenders evaluate whether you can comfortably service the loan by:
- Applying a buffer (usually 2-3%) to the current interest rate
- Using the Higher of Actual Expenses or Household Expenditure Measure (HEM)
- Considering your employment stability and income type
- Assessing your savings history and deposit amount

How to Improve Your Borrowing Power
1. Increase Your Income
- Negotiate a raise or promotion at your current job
- Take on additional part-time work or freelance projects
- Develop passive income streams (rental properties, investments)
- Consider changing careers to a higher-paying field
2. Reduce Your Expenses
- Create and stick to a strict budget
- Cut unnecessary subscriptions and memberships
- Reduce discretionary spending (dining out, entertainment)
- Refinance existing debts to lower interest rates
- Consider downsizing your current living situation
3. Improve Your Credit Score
- Pay all bills and loan repayments on time
- Reduce credit card limits and avoid maxing out cards
- Limit applications for new credit
- Check your credit report for errors and dispute inaccuracies
- Maintain long-standing credit accounts
- Use different types of credit responsibly (credit cards, personal loans)
4. Save a Larger Deposit
A larger deposit not only reduces the amount you need to borrow but also:
- Improves your loan-to-value ratio (LVR)
- May help you avoid Lenders Mortgage Insurance (LMI)
- Demonstrates financial discipline to lenders
- Can help you secure better interest rates
| Deposit Amount | Property Value | LVR | LMI Required | Estimated Borrowing Power |
|---|---|---|---|---|
| $20,000 (5%) | $400,000 | 95% | Yes | $380,000 |
| $40,000 (10%) | $400,000 | 90% | Yes | $360,000 |
| $80,000 (20%) | $400,000 | 80% | No | $420,000 |
| $100,000 (25%) | $400,000 | 75% | No | $450,000 |
Common Mistakes to Avoid
- Overestimating your borrowing power: Just because a lender approves you for a certain amount doesn’t mean you should borrow that much. Consider your personal comfort level with repayments.
- Ignoring rate rises: Many borrowers don’t account for potential interest rate increases. Always stress-test your budget with higher rates.
- Forgetting about additional costs: Remember to budget for stamp duty, legal fees, building inspections, moving costs, and potential renovations.
- Changing jobs before applying: Lenders prefer stable employment history. Changing jobs shortly before applying for a loan can reduce your borrowing power.
- Making large purchases before settlement: Taking on new debts (like a car loan) between approval and settlement can jeopardize your loan.
- Not shopping around: Different lenders have different criteria. Always compare multiple options to find the best deal.
Government Schemes That Can Help
Several government initiatives can help first-home buyers and others enter the property market:
First Home Loan Deposit Scheme (FHLDS)
Allows eligible first-home buyers to purchase a home with a deposit as low as 5% without paying Lenders Mortgage Insurance (LMI). The government acts as guarantor for up to 15% of the property’s value.
Eligibility:
- Australian citizens (not permanent residents)
- Minimum age of 18 years
- Taxable income up to $125,000 for individuals or $200,000 for couples
- First home buyers (or haven’t owned property in Australia in last 10 years)
More information: National Housing Finance and Investment Corporation
First Home Super Saver Scheme (FHSSS)
Allows you to save money for your first home inside your superannuation fund, where it’s taxed at a lower rate. You can then withdraw these contributions (plus earnings) to put toward your home deposit.
Key Features:
- Maximum releasable amount of $50,000 per person
- Maximum annual contribution of $15,000
- Contributions must be within existing super contribution caps
- Must live in the property for at least 6 months within the first year

Advanced Strategies for Maximizing Borrowing Power
1. Debt Consolidation
Combining multiple debts into a single loan with a lower interest rate can:
- Reduce your monthly repayments
- Improve your debt-to-income ratio
- Simplify your financial management
- Potentially improve your credit score
2. Using a Guarantor
A family member (usually a parent) can act as guarantor using their property as security. This can:
- Allow you to borrow 100% (or more) of the property value
- Help you avoid Lenders Mortgage Insurance
- Potentially secure better interest rates
- Increase your borrowing power significantly
Risks: The guarantor’s property is at risk if you default on the loan.
3. Interest-Only Loans
For a limited period (usually 1-5 years), you only pay the interest on the loan. This can:
- Lower your initial repayments
- Increase your borrowing power in the short term
- Free up cash for investments or renovations
Considerations: After the interest-only period, repayments will increase significantly as you start paying both principal and interest.
4. Offset Accounts
An offset account is a transaction account linked to your home loan. The balance in this account is offset against your loan balance, reducing the interest you pay. Benefits include:
- Reduces the interest charged on your loan
- Can help you pay off your loan faster
- Provides flexibility to access your savings
- May improve your borrowing power by reducing interest costs
The Impact of Interest Rates on Borrowing Power
Interest rates have a significant impact on how much you can borrow. Even small changes can make a big difference in your borrowing power and repayments.
| Interest Rate | Borrowing Power | Monthly Repayment | Total Interest Paid |
|---|---|---|---|
| 3.00% | $650,000 | $2,775 | $339,000 |
| 4.00% | $580,000 | $2,775 | $457,000 |
| 5.00% | $520,000 | $2,775 | $563,000 |
| 6.00% | $470,000 | $2,775 | $659,000 |
| 7.00% | $430,000 | $2,775 | $745,000 |
As you can see, a 1% increase in interest rates can reduce your borrowing power by approximately 10-15% while keeping the same monthly repayment amount.
Working with Mortgage Brokers
A good mortgage broker can be invaluable when trying to maximize your borrowing power. They can:
- Access loans from multiple lenders, including those not available to the public
- Help you understand complex loan features and structures
