How to use these calculators.

These calculators provide quick, reliable estimates for Melbourne mortgage scenarios. The math behind each is based on standard Australian lending formulas, current Victorian stamp duty brackets, and conservative LMI rate bands.

They're built for two purposes: sanity-checking your assumptions before you go house hunting or refinance, and modelling scenarios when you're comparing options. The repayment and borrowing power calculators are typically the first stop; the stamp duty and LMI calculators help you understand the full upfront cost of a purchase.

Mortgage Repayment Calculator

The most-used calculator on most broker websites — for good reason. Knowing what your monthly (or fortnightly, or weekly) repayments will be is the foundation of every other decision. Adjust the loan amount, interest rate, and term to model different scenarios. Try switching from monthly to fortnightly repayments to see how the small structural change makes a meaningful difference over the life of the loan.

Borrowing Power Calculator

Estimates how much you could likely borrow based on your gross income, existing debts, and dependents. It applies a conservative buffer (lenders typically assess borrowing capacity at a rate 3% above current rates, per APRA guidance) and standard living expense benchmarks. The output is indicative — actual lender decisions vary, and we strongly recommend you don't make purchase commitments based on calculator output alone.

Stamp Duty Calculator (Victoria)

Victorian stamp duty (formally "land transfer duty") is one of the biggest upfront costs of a property purchase, often $20,000-$60,000+ for typical Melbourne homes. The calculator applies current VIC brackets and handles four buyer types: owner-occupier (PPR), first home buyer (with exemption and concession bands), investor, and foreign purchaser (with 8% surcharge).

LMI (Lenders Mortgage Insurance) Calculator

When borrowing more than 80% of a property's value, lenders typically require LMI to protect themselves. The premium is paid by you, often capitalised into the loan. Our calculator uses indicative LMI rate bands across LVR levels (80%, 85%, 90%, 95%+) and includes an investor surcharge approximation. Actual premiums vary by lender.

Refinance Savings Calculator

Calculates the difference between your current repayments and what they'd be at a lower rate, then projects that saving across the remaining loan term. A useful sanity-check before going through a refinance application — though the calculator can't account for exit fees, application fees, or loan structure improvements beyond the rate.

Extra Repayments Calculator

Sometimes the most surprising calculator. Even $200-$500 a month in extra repayments can shave 5-7 years off a 30-year loan and save tens of thousands in interest. This calculator shows the time saved and interest saved for any extra repayment amount.

Melbourne Context

Why Melbourne mortgage math is different.

Mortgage calculators built for the broader Australian market don't always reflect Melbourne realities. Victorian stamp duty brackets differ from NSW or Queensland. The median Melbourne home price (currently around $940,000 for houses, $580,000 for units) places most borrowers into specific LMI bands and stamp duty brackets.

Our calculators are tuned for these specifics. The stamp duty calculator uses VIC brackets, not generic ones. The borrowing power calculator uses the 2024-25 Australian tax brackets. The LMI bands reflect typical insurer pricing rather than a single-rate approximation.

That said — calculators are guides, not commitments. Actual lender assessments factor in your full circumstances, lender-specific policies (some lenders are more generous on certain income types; others have stricter LVR limits in certain postcodes), and the property itself (some Melbourne apartments are difficult to finance regardless of borrower strength). For the real numbers, book a consultation.
