Refinance Savings Calculator

Our free refinance savings calculator compares your current loan to a lower rate and shows your monthly saving, annual saving, and total interest saved over the remaining loan term, along with the break-even point after accounting for switching costs including discharge fees, application fees, break costs, and any cashback incentive.

Enter your current loan details, the rate you are considering, and your estimated switching costs to get a complete picture. Not sure what rate you could qualify for?

Important: Results are indicative only. The calculator compares two fixed interest rates over the same remaining loan term. It assumes a constant rate for the full term and does not account for changes in rate, additional fees charged over the life of the loan, LMI on refinancing, or changes to loan features. Break costs for fixed rate loans should be confirmed with your current lender as they vary significantly. Cashback offers from lenders are subject to eligibility conditions and may be clawed back if the loan is refinanced again within a specified period. Consult a Stanford Financial broker for a personalised assessment.

How Much Can Refinancing Save You?

The saving from refinancing comes entirely from the difference in interest rate. A lower rate means less interest is charged each day on your outstanding balance, which reduces both your monthly repayment and the total interest paid over the remaining loan term. Small rate differences compound significantly over long terms on large balances.

BalanceCurrent RateNew RateMonthly SavingBreak-even
$500,0007.00%6.00%~$311/mo~2.7 months
$500,0007.00%6.50%~$157/mo~5.4 months
$600,0007.20%6.20%~$385/mo~2.2 months
$600,0007.00%6.50%~$188/mo~4.5 months
$700,0007.50%6.50%~$432/mo~1.9 months
$800,0007.00%6.20%~$387/mo~2.2 months


Indicative only. Based on 25-year remaining term, $850 total switching costs. Monthly saving is the difference between minimum repayments at each rate. Break-even assumes switching costs divided by monthly saving. Use the calculator above for your exact figures.

On a $600,000 loan, moving from 7.00% to 6.20% saves approximately $387 per month. Over a 25-year remaining term, the total interest saved is approximately $116,000. After $850 in switching costs, the break-even point is around 2.2 months after which every month is pure saving.

What Are the Costs of Refinancing?

Refinancing is not free, but the costs are typically modest relative to the potential saving. The main costs to factor in are:

Cost ItemTypical RangeNotes
Discharge fee$150 – $500Charged by your current lender to formally close your loan and release the mortgage. Amount varies by lender.
Application / setup fee$0 – $600Some lenders charge an upfront fee for a new loan. Many competitive lenders charge nothing. Check the new lender’s PDS.
Break cost (fixed)$0 – $50,000+Only applies if you are exiting a fixed rate loan before the end of the fixed period. Can be very large. Get the exact figure from your lender before proceeding.
Legal / settlement$200 – $400Some lenders include this in their fee structure. Your broker will clarify what is included.
Cashback incentiveUp to $4,000+Many lenders offer cashback for refinancers, typically $2,000–$4,000. This offsets switching costs and can make the break-even point immediate. Subject to eligibility conditions.


For most borrowers on a variable rate loan, total switching costs fall in the $500–$1,500 range. At a monthly saving of $300–$400, that is a break-even period of 1.5–5 months — after which you are ahead. A cashback from the new lender can reduce net switching costs to zero or even make refinancing immediately profitable.

Break Costs on Fixed Rate Loans

If you are on a fixed rate loan, the break cost calculation is based on the difference between your contracted fixed rate and current wholesale rates for the remaining fixed term, applied to your outstanding balance. The formula is complex and the amount can be substantial potentially tens of thousands of dollars — if rates have fallen significantly since you fixed. Always request an exact break cost figure from your lender before signing anything with a new lender.

When Is It Worth Refinancing?

Refinancing is almost always worth considering if:

  • Your loan is more than 2 years old and you have not reviewed your rate in that period
  • You are on a variable rate and your current rate is more than 0.5% above the most competitive rates available for your LVR and loan size
  • Your financial situation has improved since you first took out the loan (higher income, lower debt, built equity) and you may qualify for better rates
  • You want to access equity in your property for renovations, investment, or another purpose
  • Your loan does not have features you now need — such as an offset account, redraw facility, or the ability to make unlimited extra repayments
  • You want to consolidate high-interest debt into a lower-rate home loan

When Refinancing May Not Be Worth It

  • You are in the final years of your loan — you are primarily repaying principal at this stage and the interest saving is smaller in absolute terms
  • You have a large fixed rate break cost that exceeds your projected savings during the remaining fixed period
  • Your LVR has risen above 80% due to falling property values and LMI would apply on the new loan. Use our LMI calculator to check this before proceeding
  • Your income situation has changed significantly and you may not qualify for the new loan on comparable terms

Loyalty tax is real. Research consistently shows that existing borrowers pay higher rates on average than new borrowers at the same lender. Lenders rely on inertia. A broker negotiating on your behalf, with a competing offer in hand, can often achieve a rate reduction from your current lender without switching at all, or identify a materially better product elsewhere. Either way, you win.

Frequently Asked Questions

How often can I refinance my home loan?

There is no legal limit on how often you can refinance. Practically, refinancing too frequently can affect your credit score (each application results in a credit enquiry), reset any cashback clawback periods, and incur switching costs repeatedly. Most financial professionals suggest reviewing your loan every 2–3 years. If your rate is materially uncompetitive, reviewing sooner is worth it regardless of when you last refinanced.

Yes, briefly. When you apply for a new home loan, the new lender performs a credit enquiry, which appears on your credit report and typically reduces your score by a small amount for a short period. Multiple applications in a short period (rate shopping) can have a more pronounced impact. A broker typically submits one application to the most suitable lender based on your profile, which is more efficient than applying to multiple lenders directly.

Most lenders require a property valuation as part of the refinancing process. This is typically arranged and paid for by the new lender at no cost to you, or included in the application fee. The valuation determines your current LVR, which affects the rate you are offered and whether LMI applies. In some cases, lenders accept an automated valuation (AVM) rather than a full physical inspection, which speeds up the process.

Yes, but LMI may apply if your LVR is above 80%. This adds a cost to refinancing that may erode or eliminate the benefit of the lower rate. Use our LMI calculator to check the LMI cost at your current property value and loan balance. Some lenders offer cashback that can offset LMI costs in specific scenarios a broker can assess this for your situation.

Refinancing typically takes 2–6 weeks from application to settlement. The main variables are the speed of the new lender’s credit assessment, valuation turnaround, and coordination with your existing lender for discharge. Refinancing is materially simpler than a new purchase — there is no contract deadline, no conveyancer managing a settlement workspace, and no simultaneous sale to coordinate. Your broker manages the process on your behalf.

Yes. If your property has increased in value since you purchased, or you have paid down a significant amount of principal, you may have equity you can access by refinancing to a higher loan amount. This is called a cash-out refinance or equity release. Common uses include home renovations, investment property deposits, debt consolidation, and other major expenses. The funds are typically paid into your nominated account at settlement. See our refinancing loans page for more detail on equity access.
