Refinancing Savings: Original Examples, Corrected Calculations and a Five-Step Checklist

A lower rate can reduce repayments and interest for comparable borrowing, but refinancing only saves money when the actual costs and terms support it. Natloans’ article of 27 November 2024, modified 3 September 2025, uses six examples and a five-step checklist. The original figures are preserved below as source observations, followed by a recalculation with explicit assumptions. They are not current offers or actual customer outcomes.

How Much Could You Save? Worked Examples

The next two tables reproduce the original article’s figures, including its rounding and arithmetic problems. Do not use them as verified savings calculations. A move from 7.11% to 6.11% is one percentage point, and 6.61% to 6.11% is half a percentage point. The article compares 30-year totals but does not fully document the calculator or all assumptions. The corrected model below makes those assumptions explicit.

Original Scenario A: 7.11% to 6.11% — source figures, not verified calculations

Loan Amount	Monthly Saving	Total Saving Over 30 Years
$500,000	$330	$118,800
$750,000	$495	$178,200
$1,000,000	$661	$237,960

Original Scenario B: 6.61% to 6.11% — source figures, not verified calculations

Loan Amount	Monthly Saving	Total Saving Over 30 Years
$500,000	$165	$59,400
$750,000	$247	$89,010
$1,000,000	$331	$119,160

The source’s Scenario B $750,000 row states $247 per month and $89,010 over 30 years, but $247 × 360 = $88,920. The other source totals are simple multiples of rounded monthly figures and do not consistently reproduce an amortising-loan calculation. No evidence establishes these example rates were available to a particular borrower at publication or today.

Use the recalculated table and its assumptions for the mathematical illustration, then obtain a comparison using your actual remaining balance, remaining term, product fees and any switching costs. A nominal 30-year total is not a present-value valuation or a forecast that rates will stay unchanged for 30 years.

5 Steps to Organising Your Refinance

Natloans outlines the following five-step process in its published article. These steps are intended as a practical guide; individual circumstances will vary.

Step 1: Evaluate Your Current Loan

• Review your loan's interest rate, fees, and remaining balance.
• Check whether your current loan has exit fees or penalties for early repayment, as these costs can affect whether refinancing is worthwhile at a given point in time.

Step 2: Research the Market

• Compare current interest rates from different lenders.
• Use a mortgage calculator to model how different rates would affect your repayments.

Step 3: Consult a Mortgage Broker

• Brokers such as Natloans provide guidance and access to loan products across multiple lenders.
• A broker can help identify which lender and product best suits your financial goals.

Step 4: Organise Your Documents

• Gather proof of income, details of your expenses, and information about your current loan.
• Check that your credit score is in good standing, as this can improve your chances of approval and the rate you are offered.

Step 5: Apply and Transition

• Once approved, your new lender will generally handle paying out your existing loan.
• Review the new loan terms carefully before signing to ensure there are no unexpected fees or conditions.

What to Consider Before Refinancing

Refinancing is not automatically beneficial in every situation. Before proceeding, it is worth weighing several factors:

• Break costs and exit fees: Some loans — particularly fixed-rate loans — carry costs for early exit. These can offset rate savings, especially if you are early in the loan term.
• Upfront costs of the new loan: Application fees, valuation fees, and legal costs associated with the new loan should be factored into your calculation.
• Remaining term: compare the same remaining repayment term first. Restarting a 30-year term can lower monthly payments while increasing total interest. The length of the remaining term alone does not prove that switching is or is not worthwhile.
• Your financial position: Lenders will assess your income, expenses, credit history, and current property value. A change in any of these since your original loan was taken out can affect what rate and product you qualify for.
• Loan features: A lower rate is not the only consideration. Offset accounts, redraw facilities, and repayment flexibility may have value that should be weighed against a headline rate.

Confirm the current costs and conditions applicable to your specific loan with Natloans or your lender before making a final decision.

Why Work with a Mortgage Broker?

Natloans says it can help compare suitable products through its lender access and manage a refinance. This is not a promise of the lowest rate in the entire market or a guarantee of financial freedom. Ask which panel options were considered, what costs apply and why the proposed structure fits the goal.

Natloans states that its team of brokers is available to guide borrowers through the refinancing process — whether the goal is securing a lower interest rate, consolidating debt, or restructuring loan terms. Specific product availability, lender access, and any applicable broker fees should be confirmed directly with Natloans.

Frequently Asked Questions

What documents will I need to gather for a refinance application?

According to the Natloans article published 27 November 2024, you should gather proof of income, details of your expenses, and information about your current loan. You should also check that your credit score is in good standing before applying, as this can improve your chances of approval. Confirm the full document requirements with your broker or lender, as these can vary. Source: natloans.com.au

Are the savings figures in the examples guaranteed?

No. The source tables include rounding and an arithmetic inconsistency. The separate corrected table uses a stated hypothetical model; actual savings depend on rates, balances, term, fees, features and eligibility. Neither table is a customer outcome or a loan offer.

How current are the interest rates used in the examples?

The rates 7.11%, 6.61% and 6.11% are numbers used in the 2024 source. Their availability at publication or now has not been verified. Obtain a dated product quote and full fee and repayment information.

Does refinancing always make financial sense?

Not necessarily. Exit fees, break costs on fixed-rate loans, and the upfront costs of a new loan can reduce or eliminate the benefit of a lower rate, particularly if you are near the end of your loan term or if the rate difference is small. A broker can help you calculate whether the net benefit justifies switching.

What happens to my existing loan when I refinance?

The refinance lender generally pays out the existing loan at settlement after required documents, security and conditions are satisfied. Approval alone does not mean the old loan has already closed. Confirm the payout amount, settlement, discharge and closure of old facilities.

Can I use a mortgage calculator to estimate savings before speaking to a broker?

Yes. The Natloans article recommends using a mortgage calculator to model how different interest rates would affect your repayments as part of your initial market research. This can help you form a clearer picture before a formal broker consultation.

Is refinancing only useful for getting a lower rate?

While a lower interest rate is a common reason to refinance, the Natloans article also mentions debt consolidation as a potential goal. Other reasons borrowers refinance can include accessing equity, changing loan features, or switching from a variable to a fixed rate (or vice versa). Discuss your specific goals with a broker to identify the most suitable approach.

How should I use the figures and policy references in this article?

Recalculated illustration with explicit assumptions

This editorial calculation uses the same opening balance for both loans, 30 years with 360 monthly payments at month-end, principal and interest, a monthly rate equal to the annual rate divided by 12, and constant rates throughout. It excludes fees, refinancing costs, offset funds, extra repayments, changing rates and daily-interest differences. Monthly values are rounded only for display; 30-year differences use unrounded payments.

Scenario	Balance	Rates	Old monthly payment	New monthly payment	Monthly difference	360-payment difference
A	$500,000	7.11% → 6.11%	$3,363.53	$3,033.20	$330.33	$118,917.94
A	$750,000	7.11% → 6.11%	$5,045.30	$4,549.81	$495.49	$178,376.91
A	$1,000,000	7.11% → 6.11%	$6,727.06	$6,066.41	$660.66	$237,835.88
B	$500,000	6.61% → 6.11%	$3,196.60	$3,033.20	$163.39	$58,821.48
B	$750,000	6.61% → 6.11%	$4,794.90	$4,549.81	$245.09	$88,232.22
B	$1,000,000	6.61% → 6.11%	$6,393.19	$6,066.41	$326.79	$117,642.96

These comparisons use an equal term, so both modelled loans finish at the same time with no remaining principal. For a shorter holding period or unequal terms, compare the outstanding loan balances as well as payments and fees. Do not interpret a lower payment alone as the net saving.

Check the net result before switching

ASIC Moneysmart’s switching guidance, checked 15 October 2026, recommends asking the current lender for a better deal, comparing remaining terms and allowing for switching costs. Include any fixed break cost, discharge and new-loan charges, mortgage registration, valuation and possible LMI. Separate one-off costs from ongoing account or package fees and any conditional cashback.

If consolidating other debts, compare their current payoff dates with the proposed schedule. Extending short debts over a mortgage term can increase interest and put the home at risk if unsecured debt becomes secured. A longer term is not mandatory; compare alternatives with repayment discipline. Borrower approval, a broker recommendation and a positive modelled saving are different findings.
