Here's what affects how much you can borrow and how to get the strongest result for your situation.

How do lenders calculate borrowing capacity in Springfield and Ipswich, QLD?

Your borrowing capacity is determined by applying your net income against a serviceability buffer of approximately 8.7% as of June 2026. Lenders take your gross income, subtract tax and existing debt commitments, then test whether you can afford repayments at this higher assessment rate - around 3% above the actual loan rate you'll pay.

The calculation follows this basic structure:

• Gross income: salary, overtime, bonuses, rental income, or self-employed earnings
• Less tax and Medicare levy: calculated at your marginal tax rate
• Less existing commitments: credit cards, car loans, personal loans, HECS debt
• Less living expenses: either actual expenses or the HEM (Household Expenditure Measure)
• Remaining income tested: against the 8.7% serviceability buffer to determine maximum loan

The difference between lenders often comes down to how they treat each of these components - particularly living expenses and income assessment for casual, contract, or self-employed borrowers.

What factors affect how much you can borrow?

Your maximum borrowing capacity is shaped by multiple factors that lenders assess differently. Income is the starting point, but your existing debts, expenses, and deposit size all play a role in determining your final loan amount.

Income type and stability:

• PAYG salary: most straightforward - recent payslips plus employment letter
• Casual or contract income: typically averaged over 12-24 months
• Self-employed income: based on tax returns, with varying add-back policies
• Overtime and allowances: some lenders include 100%, others discount or exclude

Existing debt commitments:

• Credit card limits: assessed at 3-4% of the total limit, regardless of balance
• Car loans: monthly repayments reduce your available income
• HECS debt: reduces income by approximately 2-8% depending on your salary level
• Personal loans: monthly commitments subtracted from serviceability

Living expenses assessment:

• HEM benchmark: standardised living cost estimates by household size
• Actual expenses: some lenders use your real spending from bank statements
• Family size: more dependants mean higher assessed living costs

How does the APRA serviceability buffer work?

The APRA serviceability buffer is a 3% safety margin that lenders must add to your actual interest rate when testing your borrowing capacity. As of June 2026, with competitive variable rates from approximately 5.69% p.a., lenders assess your application at approximately 8.7% to confirm you can afford repayments even if rates rise.

This buffer affects every borrower the same way, but how lenders calculate your income and expenses varies significantly. Two lenders testing the same borrower at 8.7% can reach different conclusions about affordability based on their income assessment and expense policies.

How the buffer works in practice:

• Your actual rate: approximately 5.69% variable (competitive new loans)
• Assessment rate: approximately 8.7% (actual rate plus 3% buffer)
• Repayment test: lender confirms your income can service the higher assessment rate
• Maximum loan: the highest amount you can service at the buffered rate

The buffer is designed to protect borrowers and the financial system from rate rises, but it also means your borrowing capacity is lower than what you could theoretically afford at today's rates.

What deposit do you need and how does it affect borrowing capacity?

Your deposit size affects both your maximum purchase price and your borrowing capacity through lenders mortgage insurance (LMI) requirements. Most lenders require 20% deposit to avoid LMI, but options exist from 5% deposit with the right loan structure.

Deposit tiers and their impact:

• 5% deposit: First Home Guarantee removes LMI for eligible buyers up to $1,000,000
• 10% deposit: LMI applies but some lenders offer competitive rates
• 15% deposit: broader lender choice, lower LMI premiums
• 20% deposit: no LMI, access to all loan products and lenders

On a $700,000 home, a 5% deposit is $35,000, 10% is $70,000, and 20% is $140,000. The difference affects not just your upfront costs but which lenders will assess your application and at what terms.

Some lenders have different serviceability policies for high-LVR loans, meaning your borrowing capacity might be lower with a 5% deposit compared to 20%, even before considering LMI costs.

How do income types affect borrowing capacity?

Different income types receive different treatment from lenders, with PAYG salary income being the most straightforward and self-employed income requiring the most detailed assessment. Understanding how your income type is evaluated helps set realistic expectations for your borrowing capacity.

PAYG Employment Income

Permanent PAYG employment is assessed using recent payslips and an employment letter. Most lenders accept base salary plus regular overtime or allowances, though policies vary on how much overtime income is included and whether probationary periods affect the assessment.

Casual and Contract Income

Casual or contract workers typically need 12-24 months of consistent income history. Lenders average your earnings over this period, and some require confirmation that ongoing work is available. Agency nurses, casual teachers, and contract professionals fall into this category.

Self-Employed Income

Self-employed borrowers need at least two years of lodged tax returns, and lenders apply different add-back policies for depreciation, equipment purchases, and other business deductions. How aggressively lenders add back these deductions can significantly affect your assessed income and borrowing capacity.

Investment and Rental Income

Rental income is typically assessed at 75-80% of the gross amount to account for vacancy and maintenance costs. Dividend income and other investment returns may require longer income history and conservative assessment rates.

What reduces your borrowing capacity?

Several factors can reduce your maximum borrowing capacity, and understanding these helps identify areas where you might be able to improve your position before applying. Some are within your control to change, while others require the right lender choice to manage effectively.

Debt commitments that reduce capacity:

• Credit card limits: assessed at full limit regardless of balance - consider reducing limits before applying
• Buy-now-pay-later accounts: some lenders include these in serviceability calculations
• Car loans and personal loans: monthly commitments directly reduce available income
• HECS debt: reduces net income based on your salary level

Income factors that can limit capacity:

• Irregular income: casual, seasonal, or commission-based earnings receive conservative treatment
• New employment: probationary periods can delay applications or require alternative lenders
• Declining income: recent pay cuts or reduced hours affect assessment
• Complex income structures: multiple income sources require more detailed documentation

Application factors:

• Credit history: past defaults, late payments, or multiple credit enquiries
• High living expenses: luxury spending can reduce serviceability under actual expense assessment
• Dependants: larger families have higher assessed living costs

How do different lenders assess borrowing capacity?

Every lender uses the same 3% serviceability buffer, but their income assessment and expense policies vary significantly. This is where mortgage broker comparison delivers the most value - identifying which lenders will give you the strongest borrowing capacity for your specific situation.

Key differences between lenders:

• Living expense assessment: HEM vs actual expenses can shift results by $30,000+ for high earners
• Overtime and allowance inclusion: some lenders include 100%, others discount or exclude entirely
• Self-employed add-backs: aggressive vs conservative treatment of business deductions
• Credit card assessment: 3% vs 4% of limits makes a meaningful difference
• Rental income treatment: 75% vs 80% assessment affects investor borrowing capacity

Specialist vs major bank differences:

• Income documentation: some non-bank lenders accept alternative income evidence
• Employment history: varying requirements for job tenure and probationary periods
• Credit history tolerance: some lenders work with borrowers who have credit issues
• Deposit source flexibility: different policies on gifted deposits or non-genuine savings

The right lender choice for your income type and situation can increase your borrowing capacity by $50,000 or more compared to approaching a lender whose policies don't suit your profile.

How to maximise your borrowing capacity

Several strategies can improve your borrowing capacity before you apply, and getting broker advice helps identify which changes will have the biggest impact for your situation. Some improvements can be made quickly, while others require longer-term planning.

Step 1: Get a broker assessment

Contact a mortgage broker to understand your current borrowing capacity and identify which lenders suit your income and deposit position. This shows you what's achievable now and what improvements would have the biggest impact.

Step 2: Reduce unnecessary debt commitments

Pay down or close credit cards you don't use, as lenders assess the full limit regardless of balance. Consider paying out car loans or personal loans if you have available funds, as this immediately improves your monthly serviceability.

Step 3: Stabilise and document your income

Maintain consistent employment and income for at least three months before applying. Gather all required documentation early, including payslips, employment letters, and tax returns for self-employed borrowers.

Step 4: Manage your expenses appropriately

If a lender uses actual expense assessment, review your bank statements and reduce discretionary spending in the 3-6 months before application. Avoid large one-off expenses that might skew your spending pattern.

Step 5: Build genuine savings

Demonstrate a savings pattern over 3-6 months, even if you're using gifted funds for part of your deposit. Regular savings show financial discipline and improve your application strength.

Step 6: Time your application strategically

Apply when your income is stable, your credit file is clean, and your savings position is strongest. Avoid applying immediately after job changes, large expenses, or credit enquiries.

Frequently Asked Questions

How much can I borrow with a $100,000 salary in Springfield and Ipswich?

Your borrowing capacity depends on your existing debts, living expenses, deposit size, and lender choice - not just your salary. A mortgage broker assessment gives you an accurate figure based on your complete financial situation.

Do all lenders give the same borrowing capacity?

No - lenders assess income and expenses differently, which can create borrowing capacity differences of $50,000 or more. How they treat your specific income type, existing debts, and living expenses varies significantly between institutions.

Can I borrow more by using actual expenses instead of HEM?

It depends on your spending patterns. High earners with modest lifestyles often benefit from actual expense assessment, while those with high discretionary spending may get better results with HEM benchmark figures.

HECS reduces your net income by approximately 2-8% depending on your salary level. The exact impact on borrowing capacity depends on your total debt position and the lender's assessment policies.

Should I pay off debt before applying for a home loan?

Generally yes - paying off credit cards, car loans, and personal loans immediately improves your serviceability. However, maintaining enough cash for deposit and costs is equally important, so get advice on the right balance for your situation.
