Home Loan Comparison for Refinancing Cost Guide Australia

Short answer: Compare refinancing options using the same balance, remaining term, repayment type and feature assumptions. Include discharge, break, application, valuation, settlement and ongoing fees; estimate the monthly change, total cost and break-even time; and test whether extending the term or borrowing more erases the benefit. A lower advertised rate does not automatically mean a cheaper refinance.

What this refinancing cost guide compares

A home loan comparison for refinancing should answer a cost question before it answers a product question: after switching expenses, ongoing fees, term changes and usable features, does the proposed loan improve the household’s stated goal over the period it expects to keep the loan? Home Loans By Choice publishes a separate lender comparison guide; this cost guide narrows the decision to refinancing assumptions, break-even time and quote questions.

No generic article can determine personal suitability or approval. Use the worksheets below to prepare consistent inputs and questions, then confirm rates, comparison rates, fees, panel, commissions, licence details and recommendations in current credit documents.

Define the refinance goal first

Common goals include reducing repayments, reducing total interest, moving from fixed to variable, changing features, consolidating eligible debt, accessing equity, removing a borrower or guarantor, changing investment structure or improving service. These goals can conflict. A lower monthly repayment achieved by extending the term may increase total interest.

Write a primary goal, a maximum acceptable repayment, the remaining loan term you want to preserve, features you will use and a date by which savings must outweigh switching cost. This prevents a comparison from drifting toward the lender with the most attractive headline.

Build the current-loan baseline

Collect the current balance, interest rate, fixed or variable split, remaining term, repayment frequency, minimum repayment, annual or package fees, offset and redraw balances, fixed-rate expiry, discharge fee and any break-cost estimate. Ask the current lender whether it can offer a lower rate or different product without an external refinance.

Moneysmart’s switching home loans guidance recommends asking the current lender for a better deal, checking lender’s mortgage insurance, reviewing switching fees and keeping the new term clear. Its guidance notes that a longer term can increase total interest even when repayments fall.

Standardise every new-loan quote

If one quote resets a 19-year remaining loan to 30 years, compare it twice: once at 19 years and once at 30. The second scenario is a separate decision, not evidence that the loan is automatically cheaper.

Count every switching cost

Moneysmart lists possible costs such as fixed-rate break fees, discharge or termination fees, application fees, internal switching fees and possible stamp duty. Other transaction-specific costs can include valuation, settlement, legal or government charges and lender’s mortgage insurance. Obtain current figures for your situation.

Calculate:

1. total upfront and financed switching cost;
2. monthly repayment difference;
3. ongoing fee difference;
4. break-even months;
5. interest and fees over the intended holding period;
6. total cost over the remaining term.

A five-year holding-period comparison can be more relevant than a 30-year total if you expect to sell, refinance or restructure sooner, but disclose the horizon.

Use a calculator as a model, not a prediction

The Moneysmart mortgage switching calculator compares current and new loans, upfront fees, regular fees, savings and the time needed to recover switching costs. Its disclaimer says results are estimates and actual amounts can differ. Use lender documents and professional advice for the final decision.

Run at least three scenarios: current rate maintained for comparison, proposed rate, and a stress rate. For variable loans, do not project one rate for decades as certainty. Record the calculator date and every input.

Put a dollar and behaviour test on features

An offset account can reduce interest when meaningful savings stay in it. Redraw can support extra repayments but access rules differ. Split loans can manage rate exposure but add structure and break-cost questions. Cashback can reduce upfront cost while distracting from a higher rate or longer-term cost.

Ask:

• Will we actually maintain an offset balance?
• Is the offset complete or partial?
• Are there account or package fees?
• How quickly can redraw be accessed and can terms change?
• Can extra repayments be made without limit?
• What happens at the end of an introductory or fixed period?
• Does the feature remain available for this exact product and borrower type?

Compare approval and property policy

The lowest rate is irrelevant if the loan does not fit income evidence, employment type, expenses, credit history, loan purpose, property type, postcode, valuation or time frame. A refinance is a new credit application and can be declined or approved on different terms.

Do not cancel the current loan, make a non-refundable commitment or rely on expected cash-out until formal approval, valuation, documents and settlement requirements are understood.

Understand the broker’s comparison

Ask which lenders are on the broker’s panel, which were considered, why the recommended option meets the goal, what alternatives were rejected, and how the broker and business are paid. ASIC’s Regulatory Guide 273 explains the best-interests obligations applicable to mortgage brokers and relevant Australian credit licensees.

Home Loans By Choice says it compares options across a lender panel. Confirm the current panel, Australian Credit Licence or credit representative details, commissions, ownership, conflicts and complaints process from the credit guide and recommendation documents. Do not infer those regulated details from an article.

Use a refinance comparison matrix

Treat cash-out as a separate borrowing decision

Adding renovation, vehicle, investment or debt-consolidation funds increases the balance and can extend the time spent paying for the expense. Compare the refinance both with and without cash-out. For debt consolidation, check whether lower repayments result from securing short-term debt against the home and stretching repayment over many years.

Moneysmart warns that refinancing or consolidation can cost more when rates or fees are higher and advises comparing all costs. Obtain legal, tax or financial advice where the purpose requires it.

Compare staying, repricing and switching

Your options may include staying unchanged, negotiating a rate reduction, switching products with the current lender, or refinancing externally. An internal change can avoid some costs but may not produce the best structure. An external refinance can improve price or features but introduces application, valuation, documentation and settlement work.

Put all four pathways in the same matrix. A retention offer should be compared by ongoing rate and features, not just convenience.

Common refinancing comparison mistakes

• Comparing advertised rates with different assumptions.
• Extending the term without showing total interest.
• Ignoring break, discharge, application and ongoing fees.
• Counting cashback as recurring savings.
• Assuming the property valuation will match expectation.
• Choosing features the household will not use.
• Applying to multiple lenders without a strategy.
• Using a calculator result as approval or prediction.
• Failing to ask the current lender for a better deal.

Prepare the evidence before requesting options

A useful comparison depends on accurate inputs. Gather the latest loan statement, current rate and expiry details, remaining term, repayment frequency, offset or redraw balance, package fees and any fixed-rate break information. Add recent income evidence, liabilities, living expenses and the property’s current use. If the refinance includes cash-out, document the amount and purpose separately.

Also note changes since the original loan: employment, household size, credit commitments, property condition, tenancy or expected retirement. A lender’s policy can make a seemingly attractive product unavailable or unsuitable for the actual scenario. Providing complete information early reduces the risk that a comparison is built around assumptions that fail later.

Stress-test the preferred option

Do not evaluate only the repayment shown at today’s quoted rate. Model a higher-rate case, a temporary income reduction and the loss of any introductory discount. Check whether the household could still meet repayments and essential costs. If the answer depends on using every dollar in an offset account, record that behaviour assumption explicitly.

For fixed rates, compare the certainty gained with break restrictions and the treatment of extra repayments. For variable rates, test how quickly a rate rise changes monthly cash flow. For split loans, confirm how fees, offsets and redraw apply to each portion. These scenarios do not predict the future; they show whether the structure remains workable when conditions change.

Keep a written decision record

Before proceeding, save the final comparison, credit proposal or recommendation, fee disclosures and the reasons the selected loan matches the stated objective. Note alternatives that were considered and why they were rejected. Confirm whether a broker receives commissions, whether lender choices come from a panel and whether any ownership or referral relationship exists. Review the final loan documents against that record before signing.

Refinancing comparison questions

How much lower should the new rate be?

There is no universal threshold. The balance, term, fees, features and holding period decide whether the difference outweighs cost.

Should I restart a 30-year term?

Only as a deliberate affordability decision after comparing total cost with your remaining term. Lower repayments can mean more interest.

Is cashback a reason to refinance?

Compare it against rate, fees, term and restrictions. A one-time amount can be outweighed by ongoing cost.

Will refinancing require a valuation?

Often a lender assesses the property, but method and requirement vary. Do not assume the resulting value.

Does a broker compare every lender?

Not necessarily. Ask about the panel and which lenders were considered for your scenario.
