Top Tips to Understand Fixed Rate Loan Fees and Costs

A fixed rate home loan can cost you more than the rate suggests, and the biggest cost only shows up if your plans change. Ambulance officers deal with roster changes, transfers and overtime swings, so the real question is whether you can live with the lock-in.

This article covers the fees that matter, how break costs work, and how a split can limit your exposure.

What Fees and Costs Come With a Fixed Rate Home Loan?

A fixed interest rate home loan can carry the same upfront and ongoing fees as a variable loan, plus break costs if you leave early and limits on extra repayments. Compare the full cost, not just the headline rate.

Break costs are the big one. Other items to ask about before you apply for a home loan include application or settlement fees, annual or package fees, and any discharge fee when the loan closes. These vary by lender, so get them in writing. The comparison rate is a useful guide because it factors in fees and charges, though it will not show you a break cost.

How Break Costs Work on a Fixed Rate Loan

A break cost is charged when you repay a fixed loan early, for example by selling or refinancing, and it recovers the lender's funding loss. If rates have risen, break costs are usually zero.

The lender locked in funding for your whole fixed term. The longer the remaining fixed period and the larger the gap between rates, the higher the potential break cost.

That means there is no standard figure. Break costs vary with the loan balance, how far wholesale rates have fallen and the time left on the fixed term. They can be zero or run to thousands of dollars. Ask your lender for a written estimate before you make any decision that would end the fixed period.

Why Extra Repayments Can Cost You on a Fixed Rate

Most fixed loans limit how much extra you can repay each year, and going over the cap can trigger break costs. Your lender's cap is in your contract.

This matters for shift workers. Overtime, back pay and penalty rate payments arrive in lumps, and the instinct is to throw them at the loan. On a fixed loan, that lump sum may hit the cap.

Offset accounts are also restricted. Many fixed loans have no offset account, or only a partial one. If you plan to park savings in a linked offset to cut interest, check whether the fixed portion allows it.

Fixed or Variable? How the Trade-Off Plays Out for Rostered Workers

A fixed rate gives you stable repayments, while a variable rate gives you flexibility. Fixing suits you if certainty matters more than being able to repay faster or move quickly.

The cost of certainty is lock-in. If you might sell, relocate for a station transfer, or refinance during the term, break costs are a real risk. The cost of flexibility is that repayments on a variable rate can rise when the interest rate moves.

Your loan term, repayment type and loan amount affect borrowing capacity and repayments, so run your numbers through our borrowing capacity calculator before choosing.

Split Rate Loans: Fix Part of Your Loan and Keep the Rest Flexible

A split loan fixes one portion of your borrowing and leaves the rest variable. It limits your break cost exposure and keeps room for extra repayments, although you only get certainty on the fixed part.

Consider an ambulance officer borrowing $500,000 over 30 years. For illustration only, we use an example rate of 6.75% p.a. on principal and interest for both portions, so the comparison is like for like.

• Whole loan at 6.75%: about $3,243 a month.
• Fixed portion of $300,000 at 6.75%: about $1,946 a month.
• Variable portion of $200,000 at 6.75%: about $1,297 a month.

The variable rate will not stay at the example rate, so the variable repayment could move up or down. Your actual repayments will depend on your lender, deposit size and rate. Use a calculator when calculating home loan repayments for your own numbers.

Now the outcome. Two years in, the officer receives a lump sum of back pay. Paying it into the $200,000 variable portion, ideally with an offset account attached, reduces interest without touching the fixed portion's repayment cap. The fixed $300,000 keeps its certain repayment. The trade-off is that the fixed portion stays locked, so if the officer sold during the term, break costs could still apply to that $300,000.

What Happens When Your Fixed Rate Ends?

When a fixed term ends, your loan usually reverts to a variable rate, which may be higher than rates you could get elsewhere. You can usually switch or refinance at that point without break costs, because the fixed period has finished.

The key is to act before expiry, not after. Our fixed rate expiry calculator shows what your repayments may look like once the term ends. If your rate has rolled over already, a loan health check can show whether another lender may suit you, and home loan refinancing explains the process and costs of switching.

Interest Only Periods and Fixed Rates: A Cost to Check

An interest only period lowers your repayments for a set time, but you do not reduce the loan balance during it. Principal and interest repayments after that period are higher because you repay the same balance over a shorter remaining term.

If your fixed term and interest only period do not line up, you could face a repayment jump at the same time as a rate change. Our interest only loans page covers when this structure is used and its risks. Map both end dates before you sign.
