A fixed interest rate home loan locks in your repayment, but it also locks in a set of costs that don't always appear in the headline comparison.
Application and Establishment Fees on Fixed Rate Products
Most lenders charge an upfront application fee when you take out a fixed rate home loan, typically between $300 and $600. Some lenders waive this during promotional periods, others bundle it into ongoing fees. The establishment fee, sometimes listed separately, can add another $200 to $400. These are sunk costs at the start of the loan, so if you're comparing a fixed rate against a variable rate with a lower or nil application fee, factor that difference into your first-year cost calculation.
Consider a borrower taking out a $500,000 fixed rate loan with a $600 application fee and a $400 establishment fee. That's $1,000 before the first repayment is made. Over a three-year fixed term, that cost averages out to around $28 per month. Not material on its own, but it stacks quickly when combined with other fixed rate conditions.
Break Costs and How They're Calculated
Break costs apply when you exit a fixed rate loan before the fixed term ends. The lender calculates the cost based on the difference between your fixed rate and the current wholesale rate the lender uses to fund loans. If wholesale rates have fallen since you fixed, you'll typically owe a break cost. If they've risen, some lenders credit you, but many don't.
The formula most lenders use is: (your rate minus current wholesale rate) multiplied by the remaining loan balance, multiplied by the remaining months in the fixed term, divided by twelve. A borrower with $450,000 remaining on a fixed rate of 5.5%, with 18 months left in the fixed term, could face a break cost of $15,000 to $20,000 if the lender's current wholesale rate sits at 3.5%. That's a real cost, not a penalty for bad behaviour. It reflects the fact that the lender has locked in funding at your original rate and can't recoup that margin if you leave early.
Break costs hit hardest when you sell, refinance to access equity, or need to consolidate debt. We regularly see borrowers who fixed for five years at a low rate during the pandemic, then needed to move or upsize two years later. The break cost in those scenarios sometimes exceeded $30,000, which wiped out any benefit from the lower rate.

Rate Lock Fees and Extension Charges
A rate lock fee applies when you want to secure a fixed rate before settlement, usually during construction or before an auction. Lenders charge between $750 and $1,500 to hold a rate for 90 days. If settlement delays and you need to extend the lock, expect another $300 to $600 per 30-day extension. Rate lock fees are non-refundable, even if the loan doesn't proceed.
This becomes relevant for buyers using construction loans or those negotiating extended settlement terms. A rate lock that rolls over three times can cost $2,500 before the loan even starts. If rates rise during that period, the lock fee might still deliver value. If rates fall, you've paid for a product you didn't need.
Ongoing Account Fees and Offset Restrictions
Most fixed rate home loans charge a monthly account fee between $10 and $15. Over a three-year fixed term, that's another $360 to $540. Some lenders bundle this into the comparison rate, others don't. Check the fine print.
Many lenders also restrict or exclude offset accounts on fixed rate products. If an offset account is available, it's often a partial offset or limited to a portion of the loan balance. Without a full offset, any surplus cash you hold in a transaction account earns interest at savings rates (currently around 1% to 2%) while your loan accrues interest at your fixed rate. That gap costs you every month. A borrower with $50,000 sitting in a non-offset account on a 5% fixed rate effectively loses around $2,500 per year in opportunity cost compared to a variable rate with a full linked offset.
Switching Fees and Refinancing Restrictions
Some lenders allow you to switch from fixed to variable during the fixed term, but they charge a switching fee of $300 to $500 on top of any applicable break costs. Others don't allow switching at all. If you're locked into a fixed rate and rates fall sharply, your only options are to wear the higher rate or pay the break cost to refinance.
Refinancing away from a fixed rate loan during the fixed term triggers the break cost as if you'd sold the property. That cost usually gets rolled into the new loan, but it still adds to your total debt. Borrowers who fixed at 2.5% during the low-rate period and then wanted to refinance to access equity or consolidate debt when rates hit 5% often faced no break cost because wholesale rates had risen. But those who fixed at 5% and wanted to refinance when rates later dropped found themselves paying thousands to exit.
Discharge Fees When You Sell or Pay Out the Loan
Every lender charges a discharge fee when you close the loan, whether at the end of the fixed term or earlier. This typically sits between $300 and $500. If you're selling the property or refinancing during the fixed term, the discharge fee applies on top of any break costs. For borrowers with multiple properties or investment loans, discharge fees compound quickly across several loans.
Discharge fees also apply if you pay out the loan early with a lump sum, even if you're not selling. Most fixed rate loans cap the amount you can pay down each year without triggering a break cost, usually between $10,000 and $30,000. Exceed that and you'll pay a break cost on the excess amount, plus the eventual discharge fee when the loan closes.
A fixed rate home loan suits borrowers who value repayment certainty and don't expect to move, upsize, or access equity during the fixed term. If your circumstances might shift, the cost structure needs to fit that risk.

Frequently Asked Questions
What fees do I pay upfront on a fixed rate home loan?
Most lenders charge an application fee between $300 and $600, plus an establishment fee of $200 to $400. Some lenders waive or bundle these during promotional periods, so check the total upfront cost before committing.
How much are break costs if I exit a fixed rate loan early?
Break costs depend on the difference between your fixed rate and the lender's current wholesale rate, multiplied by your remaining loan balance and the months left in the fixed term. If wholesale rates have fallen, break costs can reach $15,000 to $30,000 on a typical loan.
Do fixed rate home loans allow offset accounts?
Many fixed rate loans restrict or exclude offset accounts. Where available, offsets are often partial or capped, which reduces their value compared to a full offset on a variable rate loan.
What is a rate lock fee and when does it apply?
A rate lock fee secures a fixed rate before settlement, typically during construction or pre-auction. Lenders charge $750 to $1,500 for a 90-day lock, with extension fees of $300 to $600 per month if settlement delays.
Can I refinance during a fixed rate term?
You can refinance during a fixed term, but you'll pay any applicable break costs plus a discharge fee. If wholesale rates have fallen since you fixed, the break cost can be substantial and may outweigh the benefit of refinancing.
