A fixed rate home loan locks your interest rate for a set period, typically between one and five years. This means your repayments remain the same regardless of what happens to the broader market during that time.
For property owners in Mandurah, where many households balance coastal lifestyle costs with mortgage commitments, this certainty can make budgeting considerably more predictable. When you know exactly what you'll pay each fortnight or month, you can plan for other expenses without worrying about sudden increases in your home loan repayments.
Rate Lock Protection During Your Fixed Period
When you fix your interest rate, the lender guarantees that rate for the duration of your fixed term. If variable rates rise by half a percentage point in that time, your repayments don't change. If they rise by two percentage points, you're still protected.
Consider a borrower who secured a fixed interest rate home loan when rates sat lower than they do currently. Their rate remains unchanged while those on variable products have seen their repayments increase multiple times. For a loan amount of $500,000, even a one percentage point difference translates to around $280 more per month in repayments.
The protection works one way only. If variable rates fall during your fixed period, you continue paying the agreed fixed rate. This is the trade you make for certainty.
Additional Repayment Restrictions
Most fixed rate home loan products limit how much extra you can pay off each year. This cap typically ranges from $10,000 to $30,000 annually, depending on the lender and product.
If you exceed this limit, the lender will charge break costs. These fees compensate the lender for the interest they lose when you repay more than expected. In our experience, borrowers who plan to make substantial additional repayments often benefit from either a variable rate or a split loan that combines both features.
Some lenders allow unlimited additional repayments on their fixed products, though these loans often carry slightly higher interest rates to compensate for that flexibility. The loan structure you choose should match how you actually use your money, not how you hope to use it.
Limited Access to Redraw and Offset Features
Fixed rate products rarely include an offset account. When an offset is available on a fixed loan, it typically offsets only a portion of your balance or comes with restrictions on how the account operates.
A linked offset on a variable rate allows every dollar in the account to reduce the interest you pay. On a fixed product, you're paying a set rate regardless of your savings balance. This difference matters significantly for borrowers who maintain substantial savings alongside their mortgage.
Redraw facilities on fixed loans, when available, often have processing times of several days and may include fees. You can't access your extra repayments with the same speed as you would on a variable product with full redraw rights.

Break Costs When You Exit Early
Break costs apply when you pay out your fixed rate loan before the term ends. This includes refinancing to another lender, selling your property, or paying a lump sum that exceeds your annual limit.
The calculation compares the interest rate you're paying with the current wholesale rate the lender can achieve for the remaining fixed period. When current rates sit below your fixed rate, break costs can be substantial. When current rates are higher, break costs may be minimal or even zero.
As an example, a borrower in Halls Head with three years remaining on a fixed term at a rate significantly higher than current wholesale rates might face break costs of $15,000 or more on a $400,000 loan. The same borrower with one year remaining might face $3,000. The calculation depends on rate movements and time, not just your loan amount.
Some lenders will waive break costs if you refinance to another product with them rather than moving to a different lender. Others reduce or waive fees for specific circumstances like relationship breakdown or relocation for work. These provisions vary between lenders and aren't guaranteed.
Portability Limitations During the Fixed Period
Most fixed rate products don't allow you to transfer the loan to a new property without breaking the fixed term. If you sell and purchase during your fixed period, you'll typically face the break costs mentioned above.
A portable loan allows you to take your existing loan to a new property. This feature is more common on variable products. When it exists on a fixed product, conditions usually apply around timing, loan amount changes, and property valuation.
For borrowers in Mandurah's growing coastal estates, where upgrading to a larger property within a few years is common, this limitation deserves attention. If you're likely to move before your fixed term expires, factor potential break costs into your decision or consider a shorter fixed period.
The Fixed Rate Expiry Decision
When your fixed term ends, your loan typically reverts to the lender's standard variable rate unless you take action. This reversion rate often sits higher than the current variable rates offered to new borrowers, sometimes by 0.5 to 1 percentage point or more.
Several months before your fixed rate expiry, you'll need to decide whether to fix again, switch to a variable product, or refinance to a different lender. Lenders typically allow you to lock in a new rate up to 90 days before your current fixed term ends, protecting you from rate movements during that transition period.
Rates at expiry may differ substantially from when you first fixed. A borrower who fixed three years ago likely secured a significantly lower rate than what's currently available. Their decision at expiry involves comparing today's fixed and variable options, not trying to replicate what they had previously.

Frequently Asked Questions
Can I make extra repayments on a fixed rate home loan?
Most fixed rate products allow extra repayments up to a set limit, typically between $10,000 and $30,000 per year. If you exceed this amount, the lender will charge break costs to compensate for lost interest.
What happens when my fixed rate term ends?
Your loan automatically reverts to the lender's standard variable rate, which is often higher than rates offered to new borrowers. You can choose to fix again, switch to a variable product, or refinance, typically within 90 days before your term expires.
Do fixed rate home loans include offset accounts?
Most fixed rate products don't include offset accounts. When an offset is available on a fixed loan, it usually offsets only a portion of your balance or comes with restrictions on how the account operates.
How are break costs calculated on a fixed rate loan?
Break costs compare your fixed interest rate with the current wholesale rate the lender can achieve for your remaining fixed period. The calculation depends on how much rates have moved and how much time remains on your fixed term.
Can I transfer my fixed rate loan to a new property?
Most fixed rate products don't allow portability without breaking the term and incurring costs. Some lenders offer portable fixed loans, but conditions typically apply around timing, loan amount changes, and property valuation.
