Borrowing Power Calculator
A quick estimate of how much you could borrow for a home loan — assessed at a stressed rate, the way a lender would. It’s arithmetic on the figures you enter, not advice on what you should borrow or an offer of finance.
Estimated borrowing power
$559,268
Based on $4,500/mo left over, assessed at 9.0% over 30 years.
Lenders test your repayments at a rate about 3% above the actual rate (APRA’s serviceability buffer), so we do too. That is why this figure is lower than a simple “repayment” sum would suggest.
This is a general estimate on the figures you enter — not credit assistance, not credit advice, and not an offer or pre-approval. It uses a simplified serviceability model and does not account for your full circumstances, lender-specific policy, deposit, LMI, or how a lender assesses different income types. What you can actually borrow will differ. Speak with an ACL-authorised mortgage broker before making any decision.
Common questions
- How is borrowing power calculated?
- We take your take-home income, subtract living expenses and existing repayments, and work out the largest loan that surplus could repay over your chosen term — assessed at your interest rate plus a 3% buffer, the way lenders test serviceability.
- Why is the number lower than I expected?
- Because lenders (and this tool) assess your repayments at about 3 percentage points above the actual rate — APRA’s serviceability buffer. It is a deliberately conservative test of whether you could still pay if rates rose.
- Is this a pre-approval or credit advice?
- No. It is a general estimate on the figures you enter, not credit assistance, an offer, or a pre-approval. Your actual borrowing capacity depends on your full circumstances and each lender’s policy. Speak with an ACL-authorised mortgage broker.
