Switching to a lower rate and then dropping to the new minimum repayment hands most of the benefit back. Keeping your current repayment on the new loan is where the real saving is.

A lower rate is not the same as a saving

A switching calculator compares two repayments. What decides whether switching is actually worth it is the gap between those repayments and the cost of moving, and how long you stay in the new loan.

The costs fall into predictable categories, even though the amounts differ by lender and by state:

  • Discharge or exit administration on the loan you are leaving.
  • Application, settlement or establishment fees on the loan you are joining. Sometimes waived, sometimes not, and often the thing a cashback offer is quietly covering.
  • Valuation. Whether it is charged, and whether it is a full valuation or a desktop one, is lender policy.
  • Government registration and mortgage fees. Set by the state land titles office, not by the lender.
  • Break costs, if you are leaving a fixed rate. These are not a fixed penalty. They depend on the lender's funding position and the time left on the fixed term, and they can be large enough on their own to make switching uneconomic.

Ask for the break cost figure in writing before you decide anything. It is the one number in this list that can change the answer completely, and it is only valid on the day it is quoted.

The loan term reset that calculators hide

This is the single most common way a switch that looks like a saving is not one.

If you are eight years into a 30-year loan and you refinance to a new 30-year term, your repayment drops partly because of the lower rate and partly because you have stretched the remaining balance back over three decades. The monthly figure improves. The total interest over the life of the loan can still go up.

The comparison worth making is not old repayment against new repayment. It is total cost to the same end date. If you switch, you can usually ask for the new loan to be written over the remaining term rather than a fresh 30 years, which keeps the comparison honest.

Two things that can stop a switch outright

Not enough equity

Refinancing is a new loan application against a new valuation. If the valuation comes in lower than you expect and your remaining balance is above 80 per cent of it, you can be up for Lenders Mortgage Insurance again on the new loan, even though you paid it the first time. LMI is not transferable between lenders.

Serviceability, reassessed from scratch

A refinance is assessed the way a new purchase is. Your income, expenses and existing commitments are all reassessed under current policy, not the policy that applied when you first borrowed. If your circumstances have changed, or if lender policy has tightened since, the new lender can decline a loan that is smaller than the one you are already paying.

Why a lender's number will differ from this estimate

A calculator works from the rate you enter. A lender does not.

Lenders regulated by APRA must assess your ability to repay at an interest rate at least three percentage points above the rate you would actually pay, a buffer APRA confirmed on 28 May 2026. That alone is usually why an approval lands below the figure a repayment estimate suggests.

Since February 2026 there is a second constraint: lenders must keep new lending at a debt-to-income ratio of six times income or above to no more than 20 per cent of their new mortgage lending each quarter. It is a quota on the lender rather than a cap on you, but it can decide whether a particular lender wants the application at all.

Current as at 28 August 2026. Reviewed quarterly, or sooner if APRA changes its settings.

Now compare the two loans you are choosing between

The calculator above answers whether moving is worth it at all. This one answers the question that comes next: of the two offers in front of you, which is actually cheaper once the revert rate and the fees are counted.

They are different questions, and the second one catches people out more often, because the loan with the better headline rate is frequently not the cheaper loan.

Why the headline rate is the wrong thing to compare

The loan with the lowest advertised rate is frequently not the cheapest loan. Three things decide the answer, and only one of them is on the billboard.

  • What the rate reverts to, and when. An introductory rate applies for a fixed period. What matters far more is the rate you pay for the remaining twenty-eight years.
  • Ongoing fees. A $10 monthly fee is $3,600 over thirty years. That is often larger than the difference the intro rate makes.
  • Upfront costs. Application, valuation and settlement fees are paid once, but they are real money and they belong in the comparison.

The default figures above illustrate the trap deliberately. Loan A looks better on the headline: a lower intro rate for two years. Loan B has no intro rate, no upfront fee and no monthly fee, and over the full term it wins comfortably. Change the numbers to the two loans you are actually weighing up.

What this calculator assumes

  • The repayment during the intro period is amortised over the full term, not over the intro period. That is how these loans are written: you pay a lower rate on the same schedule, you do not pay the loan off faster.
  • At revert, the repayment is recalculated on the balance that remains, at the revert rate, over the remaining term.
  • Rates are assumed to hold for the whole term. A variable rate will not, so treat a thirty year total as a way of ranking two loans against each other rather than as a forecast.
  • Repayments are monthly and fees are not capitalised into the balance.

Not included: LMI, stamp duty, offset or redraw benefits, and cashback offers. A cashback is worth including in your own arithmetic as a reduction in upfront cost, but check what it is buying: a retention offer is often not the win it appears to be.

FAQs

Mortgage Switching Questions Answered

Learn how refinancing works, what costs to consider and how switching lenders may affect your repayments, borrowing power and long-term financial goals.

Many homeowners focus on interest rates alone, but refinancing is often about more than securing a lower rate.

A mortgage switch may be worthwhile if it reduces repayments, lowers interest costs, provides access to better loan features or supports future goals such as investing, debt consolidation or accessing equity. Even a small rate difference can result in significant savings over the life of a loan, particularly on larger loan balances.

The answer depends on your current interest rate, loan balance and remaining loan term.

Some homeowners discover only modest savings, while others find that refinancing could reduce interest costs by thousands of dollars over time. A mortgage switching calculator can provide a useful estimate, but the actual outcome depends on the loan products being compared and any associated refinancing costs.

Not necessarily.

A lower interest rate may reduce repayments, but loan features, flexibility and lender policy can be equally important. For example, some loans include offset accounts, more flexible repayment options or better policies for future borrowing.

The cheapest loan today is not always the most suitable loan for your long-term plans.

Refinancing may involve costs such as discharge fees, government registration fees and settlement expenses.

However, many lenders also offer refinance incentives or cashback promotions from time to time. The key question is not whether there are costs, but whether the potential savings outweigh those costs over the period you intend to keep the loan.

A refinance application may result in a credit enquiry being recorded on your credit file.

In most cases, a single refinance application has a limited impact. What lenders are generally more interested in is your overall credit history, repayment conduct and existing financial commitments.

Potentially, and this is one of the most common reasons homeowners refinance.

If your property has increased in value, you may have access to additional equity. Some borrowers use this equity for renovations, investment property purchases, debt consolidation or other financial goals.

A refinance can provide an opportunity to reassess your overall lending structure rather than simply changing lenders.

Lenders will assess your current financial position when reviewing a refinance application.

This can work in your favour if your income has increased, but it may also affect eligibility if your circumstances have changed. Different lenders assess income, overtime, bonuses, allowances and self-employed earnings differently, which is one reason refinance outcomes can vary significantly between lenders.

Not all lenders assess applications in the same way.

Two lenders may review the same borrower and reach different conclusions based on their policies, servicing calculations and approach to income assessment. We've seen situations where a borrower was declined by one lender but approved elsewhere because another lender viewed their income or financial position differently.

A decline from one lender does not automatically mean refinancing is no longer possible.

There is no universal answer.

For some homeowners, accessing equity can create opportunities such as investing, renovating or consolidating debt. For others, maintaining their existing structure may be more appropriate. The right strategy depends on your objectives, cash flow and future plans rather than simply how much equity is available.

Many homeowners only review their mortgage when interest rates rise, but that is not the only reason to reassess a loan.

Changes in income, property values, family circumstances, investment plans or lending policies can all create opportunities that did not exist when the loan was originally established. Even borrowers who are happy with their current lender often benefit from reviewing their options periodically.

Sometimes the biggest benefits of refinancing have nothing to do with the headline rate.

A different lender may offer better loan features, more flexible policies, stronger borrowing capacity, improved cash flow or a structure that better supports future property purchases. This is why experienced investors often look beyond the advertised rate when comparing refinance options.

Many experienced investors regularly review their lending structure because lender policies, borrowing capacity and loan features can change over time.

The goal is not to refinance for the sake of refinancing. Rather, it is to ensure the loan continues to support their broader property and investment strategy. In some cases, a simple loan review can identify opportunities that were not available when the original loan was established.
