Everything You Need to Know About Fixed Rate Loan Terms

How Long Should You Fix Your Home Loan Rate?

Most lenders offer fixed rate terms from one to five years, with some extending to ten. The right term depends on how long you want protection from rate rises and how likely you are to refinance, sell or pay down extra before the fixed period ends.

A borrower purchasing in Hawthorne with a $700,000 loan might lock in for three years to cover the period they expect rates to stay elevated, then revert to variable once the market stabilises. That same borrower might avoid a five-year fix if they're planning to renovate and refinance within four years, since breaking early would trigger exit costs.

Shorter fixed terms give you less time locked in but also less protection if rates keep climbing. Longer terms lock in your rate for extended certainty but reduce your ability to respond if your circumstances shift or if variable rates fall sharply.

What Happens When Your Fixed Rate Term Ends

Your loan reverts to the lender's standard variable rate unless you arrange to refix or refinance beforehand. Standard variable rates are typically higher than the discounted variable rates advertised to new customers, which can mean a sharp jump in repayments.

In our experience, borrowers often underestimate how much their repayments will increase at reversion. A loan that was costing $3,800 a month on a fixed rate might jump to $4,400 or more if the standard variable rate sits 1.5 percentage points above the original fixed rate. That difference compounds if you're also facing higher living costs or reduced household income at the time of reversion.

Planning ahead means reviewing your loan at least three to six months before the fixed term expires. You can negotiate a new fixed rate with your current lender, switch to a discounted variable product, or refinance to a new lender with a lower ongoing rate. Waiting until after reversion removes most of your negotiating position.

Fixed Rate Break Costs and Why They Matter

Break costs apply when you exit a fixed rate loan early by refinancing, selling or making a large lump sum repayment beyond any annual allowance. The lender calculates the cost based on the difference between your fixed rate and the current wholesale rate for the remaining term, adjusted for the outstanding loan balance.

Consider a borrower in Hawthorne who fixed $600,000 at 5.8% for five years when wholesale rates were also elevated. Two years later, wholesale rates have dropped to 4.5%. The lender is now funding that loan at a lower cost but still receiving the higher fixed rate, so if the borrower exits early, the lender charges a fee to recover the lost income. That fee could be $15,000 or more depending on how far rates have moved and how much time remains on the fixed term.

Break costs are not charged as a penalty for bad behaviour. They reflect the actual economic loss to the lender. If wholesale rates have risen since you fixed, the break cost may be zero or even result in a small credit, though lenders rarely pass that credit on in full.

Can You Make Extra Repayments During a Fixed Rate Term

Most lenders allow extra repayments up to a set limit during a fixed rate period, typically $10,000 to $30,000 per year depending on the loan product. Repayments above that threshold may trigger break costs even if you're not refinancing or selling.

A borrower with a $650,000 fixed rate loan and an annual $20,000 extra repayment allowance could pay down $20,000 each year without penalty. If they receive an inheritance or bonus and want to pay off $80,000 in one go, the amount above $20,000 would likely attract break costs unless the lender's wholesale funding rate has risen since the loan was fixed.

Some fixed rate products allow no extra repayments at all. If paying down your loan ahead of schedule is a priority, a split rate structure with part fixed and part variable gives you the option to direct lump sums to the variable portion without restriction.

Should You Split Your Loan Between Fixed and Variable

A split loan divides your borrowing between a fixed portion and a variable portion, usually in a ratio like 50/50 or 70/30. You get partial protection from rate rises on the fixed portion while keeping flexibility on the variable portion for extra repayments and access to features like an offset account.

In a scenario where a Hawthorne buyer borrows $750,000, they might fix $500,000 for three years and leave $250,000 on variable. The fixed portion locks in certainty for the bulk of the loan, while the variable portion allows them to park savings in offset and make unlimited additional repayments as their income allows. If they need to refinance or sell within the fixed term, the break cost applies only to the $500,000 fixed portion, not the entire loan.

The downside is that managing two loan accounts can mean two sets of fees and slightly more admin. Some lenders also apply different interest rate discounts to split loans compared to single-product loans, so the effective rate on each portion may not match the headline advertised rate.

How to Choose the Right Fixed Rate Term for Your Situation

Start with how long you expect to keep the loan in its current form. If you're likely to sell, refinance, or make large lump sum payments within two years, a long fixed term exposes you to unnecessary break cost risk. If you want sustained protection and have no plans to move or restructure, a longer term may suit.

Location and property type also matter. Hawthorne sits close to the CBD and the riverfront precincts along Lytton Road and Hawthorne Road, and properties in this area often attract buyers with stable, longer-term intentions. That profile lends itself to three- or five-year fixed terms more comfortably than locations with higher turnover or where buyers are more likely to upsize quickly.

Your income stability and repayment buffer also influence the decision. A fixed rate provides certainty, but it removes your ability to benefit from rate cuts. If you're in a position to absorb rate increases and prefer the option to refinance or pay down the loan quickly, variable or split structures may be more suitable. If your income is less predictable or you're at the edge of your borrowing capacity, locking in a rate removes one major source of repayment risk.
