Fixed rate home loans lock your interest rate for a set period, typically one to five years. Some lenders offer longer terms up to 10 years. Your repayments stay the same regardless of market movements during this period.
This certainty comes with trade-offs. Fixed rates often start higher than variable rates. You sacrifice flexibility for predictability. Understanding these dynamics helps you choose the right structure for your situation.
How Fixed Rate Home Loans Work
Your lender sets your interest rate when you settle the loan or when your fixed period begins. This rate cannot change until the fixed term expires. Your principal and interest repayments remain constant throughout this period.
Most fixed rate terms run from one to five years. Longer terms typically carry higher rates. A five-year fixed loan usually costs more than a three-year fixed loan at the time of approval, subject to lender assessment.
When your fixed period ends, your loan typically reverts to the lender's standard variable rate unless you negotiate a new fixed term.
Fixed Rate Benefits
Payment certainty is the primary advantage. You know exactly what you will pay each month. This makes budgeting straightforward and removes interest rate anxiety.
Fixed rates protect you from rate rises during your term. If variable rates increase significantly after you fix, you continue paying your locked rate. This may reduce your repayments compared to variable loans, depending on your circumstances and market movements.
Rate protection works best when you fix at relatively low rates before increases occur.

Fixed Rate Limitations
Reduced flexibility is the main drawback. Most fixed rate loans restrict extra repayments. Some lenders allow additional payments up to $10,000 or $20,000 annually, but these limits vary significantly.
Offset accounts are rarely available with fixed rates. When offered, they typically provide partial offset only. This removes a key tax-efficient savings strategy available with variable loans.
Redraw facilities are usually unavailable or severely restricted during fixed periods.
Break Costs Explained
Breaking your fixed rate before the term expires may trigger break costs. These apply when you:
- Exit the loan early
- Make large prepayments beyond allowed limits
- Switch to a different product or rate type
- Sell the property
Break costs protect lenders from interest rate risk. If market rates have fallen since you fixed, the lender faces a loss when your fixed term ends early. They pass this cost to you.
Calculating break costs is complex. Each lender uses different formulas. The calculation typically compares your fixed rate to current wholesale rates for the remaining term. Larger gaps create higher break costs.
Break costs can reach tens of thousands on large loans when rate gaps are significant.
Rate Lock Options
Some lenders offer rate lock facilities. This secures your fixed rate from application to settlement, protecting you from rate rises during the approval process.
Rate lock fees typically range from 0.15% to 0.50% of your loan amount. On a $600,000 loan, this costs $900 to $3,000. Some lenders waive these fees or include them in other costs.
Rate locks usually last 90 days. Extended settlements may require renewal and additional fees. The fee is non-refundable if you do not proceed with the loan.
Fixed vs Variable: Making the Choice
Fixed rates suit borrowers who prioritise payment certainty over flexibility. Variable rates suit those who want to make extra repayments, use offset accounts, or may sell within a few years.
Your loan size affects this decision. Break costs hit larger loans harder. A $300,000 loan faces different constraints than an $800,000 loan when considering early exit scenarios.
Time horizons matter. If you plan to sell or refinance within two years, fixed rate restrictions may outweigh benefits.
Current Market Considerations
Fixed rates typically start higher than variable rates to compensate lenders for interest rate risk. The gap between fixed and variable rates reflects market expectations about future rate movements.
A 0.5% gap on a $500,000 loan adds roughly $200 to your monthly repayments initially. Whether this premium is worthwhile depends on your circumstances and risk tolerance.

Split Loan Alternative
Split loans combine fixed and variable portions. You might fix 60% of your loan and keep 40% variable. This provides partial payment certainty while maintaining some flexibility for extra repayments and offset accounts.
Split ratios are flexible. Some borrowers fix small portions for basic payment security while keeping most of their loan variable. Others fix larger portions during uncertain rate environments.
Professional Assessment
Your mortgage broker can model different scenarios across multiple lenders. Interest rate structures, break cost formulas, and flexibility features vary significantly between lenders.
LVR, loan purpose, and employment type all influence which lenders offer the most competitive fixed rates for your situation. LVR limits vary by lender and are subject to individual assessment.
