How this estimate is calculated

Base salary is assessed at 100%; overtime, bonus, commission, rental and other income at 80% — standard lender shading.
Tax uses the current ATO resident individual tax scale, the Low Income Tax Offset, and the Medicare Levy.
HECS-HELP compulsory repayments are calculated from current ATO thresholds when applicable.
Living expenses are assessed at the higher of your declared figure and a modelled HEM benchmark.
Credit and store cards are assessed at 3.8% of the limit per month, regardless of balance.
The new loan repayment is assessed at your rate plus the APRA serviceability buffer, not the actual rate you'd pay today.

This estimate is generated from the details you provided and general industry assumptions, including a modelled approximation of the Household Expenditure Measure (not the licensed lender dataset). Actual results will vary by lender — speak with a credit representative before making financial decisions.

Why this matters

Refinancing can reduce your interest payments, lower your monthly repayment, and help you pay your loan off sooner. Most clients refinancing save around 0.5%–0.7% on rate, which often means $150–$250+ per month back in their pocket. This data is derived from Finder, Money.com.au and PEXA refinance data across average Australian loan sizes.
