Your Estimated Borrowing Power
Comprehensive Guide: How Much Can I Borrow with Commonwealth Bank (CBA)?
When considering a home loan with Commonwealth Bank (CBA), one of the most important questions is “How much can I borrow?” This comprehensive guide will walk you through everything you need to know about CBA’s borrowing calculator, the factors that influence your borrowing power, and how to maximize your home loan potential.
Understanding CBA’s Borrowing Calculator
The Commonwealth Bank borrowing power calculator is a sophisticated tool designed to give you an estimate of how much you might be able to borrow for a home loan. This calculator takes into account multiple financial factors to provide a personalized estimate that aligns with CBA’s lending criteria.
Key features of CBA’s calculator include:
- Income assessment (primary and secondary sources)
- Expenses and financial commitments analysis
- Loan term and interest rate considerations
- Dependents and living situation factors
- Existing debt and loan repayments
Factors That Affect Your Borrowing Power with CBA
Several key factors influence how much Commonwealth Bank will lend you:
- Income: Your primary income is the foundation of your borrowing power. CBA typically considers:
- Base salary (PAYG employees)
- Overtime and bonuses (usually averaged over 1-2 years)
- Commission income (often assessed at 80% of the amount)
- Rental income (typically assessed at 80% of the rental amount)
- Investment income (dividends, interest, etc.)
- Expenses: CBA uses the HEM (Household Expenditure Measure) benchmark but also considers your declared living expenses. They’ll look at:
- Groceries and household items
- Utilities (electricity, gas, water)
- Insurance premiums
- Transportation costs
- Entertainment and leisure
- Childcare and education expenses
- Existing Debts: All current financial commitments reduce your borrowing power:
- Credit card limits (even if not fully utilized)
- Personal loans
- Car loans
- Other home loans
- Buy Now Pay Later commitments
- Loan Details:
- Loan term (typically 25-30 years for owner-occupiers)
- Interest rate (current CBA rates or your negotiated rate)
- Loan type (principal & interest vs. interest-only)
- Loan purpose (owner-occupied vs. investment)
- Personal Circumstances:
- Number of dependents
- Marital status
- Employment stability
- Credit history
How CBA Calculates Your Borrowing Power
Commonwealth Bank uses a serviceability assessment to determine how much you can borrow. This assessment follows these general steps:
- Income Assessment: CBA calculates your net income after tax and other deductions. They typically use:
- 80% of overtime and bonus income
- 80% of rental income
- 100% of base salary for PAYG employees
- Average of last 2 years’ income for self-employed borrowers
- Expense Calculation: CBA applies either:
- The HEM benchmark (which varies based on your income and family size), or
- Your declared living expenses (whichever is higher)
- Debt Assessment: All existing debts are factored in at their minimum repayment amounts, with buffer rates applied (typically 3% above the current rate for variable loans).
- Buffer Application: CBA applies an assessment rate (currently around 3% above the loan’s interest rate) to ensure you can afford repayments if rates rise.
- Net Surplus Calculation: Your net income minus expenses and debt repayments determines your borrowing capacity.
| Loan Type | Actual Rate | Assessment Rate | Buffer |
|---|---|---|---|
| Owner Occupied P&I | 6.25% | 9.25% | 3.00% |
| Investment P&I | 6.75% | 9.75% | 3.00% |
| Owner Occupied IO | 6.50% | 9.50% | 3.00% |
| Investment IO | 7.00% | 10.00% | 3.00% |

Common Mistakes to Avoid When Using CBA’s Calculator
While the CBA borrowing calculator is a powerful tool, many people make these common mistakes:
- Underestimating expenses: Many applicants underreport their living expenses, which can lead to an overestimation of borrowing power that won’t hold up in the actual application.
- Forgetting about buffers: The calculator might show results based on current rates, but CBA applies a 3% buffer in their actual assessment.
- Ignoring future changes: Failing to account for upcoming life changes (like having a baby or career changes) that could affect your financial situation.
- Not considering all debts: Forgetting to include all credit cards, personal loans, or buy-now-pay-later commitments.
- Assuming pre-approval is final: Pre-approval amounts can change when you find a specific property and submit a full application.
- Not shopping around: Relying solely on CBA’s calculator without comparing with other lenders’ assessments.
CBA’s Borrowing Power vs. Other Major Banks
Different banks have different lending criteria, which can result in varying borrowing power assessments. Here’s how CBA generally compares to other major Australian lenders:
| Lender | Estimated Borrowing Power | Assessment Rate Buffer | HEM Usage | Living Expense Treatment |
|---|---|---|---|---|
| Commonwealth Bank | $720,000 – $780,000 | 3.00% | Yes (but considers declared expenses) | Uses higher of HEM or declared |
| ANZ | $700,000 – $760,000 | 3.00% | Yes | Uses HEM for most applicants |
| NAB | $750,000 – $810,000 | 2.50% | Yes (but more flexible) | Case-by-case assessment |
| Westpac | $680,000 – $740,000 | 3.00% | Yes (strict) | Uses HEM for most applicants |
| Macquarie | $780,000 – $850,000 | 2.50% | No (uses declared expenses) | More flexible assessment |
Note: These are approximate comparisons and actual borrowing power can vary significantly based on individual circumstances. The assessment rate buffer has been a particular focus of APRA (Australian Prudential Regulation Authority) regulations in recent years.
The Role of LVR in CBA’s Borrowing Calculations
Loan-to-Value Ratio (LVR) is a crucial factor in CBA’s lending decisions. LVR is calculated as:
(Loan Amount / Property Value) × 100 = LVR%
CBA’s LVR policies generally work as follows:
- Up to 80% LVR: No Lenders Mortgage Insurance (LMI) required. You’ll typically get the best interest rates in this range.
- 80.01% to 90% LVR: LMI required. CBA will arrange this through their preferred provider (Genworth or QBE). The premium is a one-off cost that can be capitalized into the loan.
- 90.01% to 95% LVR: Higher LMI premiums apply. CBA offers some products in this range, particularly for first home buyers with strong income.
- Above 95% LVR: Generally not available through CBA, though some exceptions exist for guarantor loans.
Your LVR affects both your borrowing power and the interest rate you’ll pay. Lower LVR loans typically come with better rates and more favorable terms.
How CBA’s Calculator Differs from a Full Assessment
It’s important to understand that CBA’s online borrowing calculator provides an estimate, while the actual assessment is more comprehensive:
| Factor | Online Calculator | Full Assessment |
|---|---|---|
| Income verification | Self-declared | Requires payslips, tax returns, etc. |
| Expense verification | Self-declared or HEM | Bank statements analyzed (3-6 months) |
| Credit history | Not considered | Full credit report check |
| Employment stability | Not considered | Employment history verified |
| Property details | Not required | Property valuation conducted |
| Interest rate buffer | May not be applied | Always applied (currently 3%) |
| Living expenses | Simple declaration | Detailed analysis of spending habits |
The full assessment process with CBA typically takes 5-10 business days and involves:
- Initial application and document submission
- Credit check and preliminary assessment
- Property valuation (if applying for a specific property)
- Final credit assessment and approval
- Formal loan offer (subject to conditions)
Special Considerations for Different Borrower Types

- May have lower assessed living expenses if currently renting with roommates
Self-Employed Borrowers
- Typically need 2 years of financial statements
- Income is usually averaged over 2 years
- May need to provide additional documentation like BAS statements
- Often assessed more conservatively than PAYG employees
