What Is a Fixed Rate Mortgage?
A fixed rate mortgage is a home loan where the interest rate remains the same for a set period, typically between 6 months and 5 years. This fixed rate period protects you from fluctuations in the market, making it easier to plan and budget your repayments.

Benefits of Fixed Rate Mortgages
- Enhanced Stability: Certainty in Repayments
Fixed repayments make budgeting easier, helping you plan your finances without surprises. Know exactly how much you’ll pay each month with a fixed home loan interest rate. - Protection from Rising Interest Rates
If interest rates increase during your fixed term, your repayments stay the same – giving you peace of mind. - Ideal for Fixed Incomes
A great option for borrowers with steady but limited income, such as first home buyers or retirees. - Helps with Long-Term Planning
Enjoy no surprises due to market volatility. You can confidently plan savings, renovations, or investments without factoring in interest rate fluctuations.
At TAG, we help clients assess whether a fixed rate aligns with their current and future plans. If you’re unsure, our expert advice can guide you toward a more tailored structure.
How Long Should You Fix Your Mortgage For?
The fixed term typically ranges from 6 months to 5 years. Choosing the right term depends on your financial goals and how long you intend to stay in the property.
- Longer Terms = Stability, but Less Flexibility
Locking in for 3-5 years means stable repayments but could see you miss out if rates drop. - Shorter Terms = More Flexibility, Less Certainty
A 16 month–2 year fixed term may offer more adaptability but expose you sooner to rate changes. - Early Repayment Fees
Breaking a fixed rate early can incur break fees, so it’s important to consider how likely your circumstances are to change.
At TAG, we help clients forecast future life events, such as growing families or refinancing opportunities so they can make the right call on the fixed period length.
Fixed vs Floating Interest Rates
When deciding between fixed and floating, it’s not just about the rate; it’s about how the structure supports your broader financial strategy. A 2-year fixed rate might give you a balance between stability and flexibility, while a 5-year fixed rate might offer better security during uncertain economic conditions.
| Feature | Fixed Rate | Floating Rate |
| Interest Rate Stability | Locked for the set term | Can go up or down anytime |
| Repayment Flexibility | Limited (fees for extra payments) | High (can make extra payments) |
| Predictability | High | Low |
| Adaptability | Lower | Higher |
Some clients choose a split loan structure, blending fixed and floating to balance certainty and flexibility. We often recommend this at TAG when clients want to hedge their bets in a changing rate environment.
Understanding Early Repayment Fees
An early repayment limit applies to all home loans with a fixed-term interest rate. Exiting a fixed-rate mortgage early, whether through refinancing, selling, or making lump sum payments, can trigger early repayment charges.
- These fees are based on market interest rate movements and how much time remains on your fixed term.
- They can be significant, so it’s important to plan ahead before locking in your rate.
At TAG, part of our job is helping you weigh whether flexibility is worth more than stability at any given time and structuring your loan accordingly.
Comparing Home Loan Rates
Don’t be lured by headline rates alone. It’s important to look at:
- Total loan cost (including fees)
- Fixed term length and break fees
- Loan features like offset accounts or redraw
- Refinancing flexibility
Need help comparing options? TAG mortgage brokers give you a personalised snapshot of what structure works best based on your income, goals, and borrowing power; not just today, but long-term.
Using Fixed Rate Mortgage Calculators
Fixed mortgage calculators are a great starting point to:
- Estimate monthly repayments
- Compare fixed vs floating structures
- Assess total loan cost over the fixed term
However, no calculator can account for future plans, potential interest rate cuts, or the impact of early break costs. That’s where tailored advice from TAG makes a real difference.

A fixed rate mortgage can provide the comfort of knowing exactly what you’ll repay each month. This repayment type is ideal for budgeting, planning, and avoiding stress from market fluctuations. But it also requires careful consideration of your life plans, risk appetite, and flexibility needs.

FAQs
What is a fixed rate mortgage?
A fixed rate mortgage is a home loan where the interest rate remains constant for a predetermined period, typically 6 months–5 years.
What happens at the end of a fixed rate term?
When your fixed rate term ends, your loan usually reverts to your lender’s standard rate or floating interest rate. This could mean:
- Higher or lower repayments depending on market interest rates
- Opportunity to re-fix, refinance or restructure
- You may be eligible for package discounts or a special interest rate on your existing lending
This is a key time to do a mortgage review with your TAG adviser.
Is a fixed-rate mortgage good in a rising interest rate market?
Yes. A fixed rate can shield you from rate hikes, protecting your monthly repayments and providing stability.
Can I make extra repayments on a fixed-rate loan?
Some lenders allow limited extra repayments, but many impose restrictions or fees. TAG can help you understand the fine print and recommend flexible options if needed.
What’s the difference between fixed and floating rates?
Fixed rates stay the same for a set period; floating rates can go up or down based on the market. The best choice depends on your goals, cash flow, and risk tolerance.
What Are the Risks of a Fixed Rate Mortgage?
- Early repayment charges: Paying off your loan balance before the end of your fixed term could mean fees apply
- Less flexibility for additional payments
