How Much Can You Borrow on a $100k Salary in Australia?
One of the most common questions buyers ask when planning to purchase property is:
“How much can I borrow on my salary?”
While every lender calculates borrowing capacity slightly differently, your income is one of the biggest factors in determining how much a bank may be willing to lend.
This guide explains how borrowing capacity works and gives realistic examples based on different income levels.
How Banks Calculate Borrowing Capacity
When lenders assess a home loan application, they don’t look at income alone. They evaluate your entire financial situation.
Key factors include:
• Your income
• Your living expenses
• Existing debts
• Credit card limits
• Number of dependents
• Interest rate buffers used by the lender

Borrowing on a $100k Salary (Single Income)
A borrower earning around $100,000 per year may be able to borrow roughly:
$450,000 – $650,000
This range depends on:
• Living expenses
• Existing debts
• Credit card limits
• Interest rates
• Lender policies
For example:
Income: $100k
Deposit: $80k
Potential purchase price: around $530k – $730k
However, these figures vary significantly depending on individual circumstances.
Borrowing on a $150k Household Income
For a couple earning a combined income of $150,000, borrowing capacity may increase significantly.
Typical borrowing ranges may be around:
$700,000 – $900,000
Again, this depends on debts, spending habits, and lender policies.
Couples may also qualify for certain government programs designed to assist buyers entering the property market.

Borrowing on a $200k Household Income
Households earning $200,000 combined income may be able to borrow approximately:
$950,000 – $1,200,000
However, lenders will still carefully review expenses and financial commitments before approving a loan.
How Debts Affect Borrowing Capacity
Existing financial commitments can reduce borrowing capacity.
Common examples include:
• Car loans
• Personal loans
• Credit cards
• Buy Now Pay Later services
• HECS / HELP debts
Even unused credit card limits can affect borrowing power because lenders assess the maximum available limit, not just the current balance.
