Include base salary, regular overtime and allowances. Exclude bonuses unless guaranteed.
Lenders typically count about 80% of rental and investment income.
Using a household benchmark estimate ($2,260/mo) based on your income and dependants — drag to override.
Car loans, personal loans, HECS/HELP. Not your current home loan (if refinancing).

Get It Checked FreeLenders don't assess you at today's rate — they add a 3% serviceability buffer to make sure you'd cope with rises. That's why your real borrowing power is lower than a simple repayment calculation suggests.
Different lenders treat income, expenses and existing debts differently, so your true maximum varies by tens of thousands between lenders. The calculator gives you the ballpark; a broker finds the lender where your ceiling is highest.
How much can I borrow for a house?
As a rough guide, lenders let you borrow the amount your after-tax income can service at the current rate plus a 3% buffer, after living expenses and existing repayments. For many double-income Perth households that's 5–6 times gross income — but it varies significantly by lender.
Why do lenders quote me different amounts?
Because their rules differ: how they count overtime, rental income, bonuses and expenses varies. The same application can support $80,000–$120,000 more with one lender than another. That spread is precisely why a 25-lender comparison matters.
