Fixed rate investment loans lock in your interest rate for a set period, typically one to five years. Most fixed rate investment loan products allow extra repayments up to a capped amount each year, usually between $10,000 and $30,000 depending on the lender, but exceeding that cap triggers break costs.
Why Extra Repayments on Investment Loans Work Differently
Most property investors structure their investment loans to maximise tax deductions, which means paying interest only or keeping principal repayments to the minimum required. Extra repayments reduce the loan balance, which reduces the interest you can claim as a deduction. That said, some investors in Eagleby choose to pay down their investment loan faster if they are planning to convert the property to an owner-occupied home later, or if they want to reduce overall debt ahead of purchasing another property.
When you fix your rate, the lender hedges that rate by locking in funding at a wholesale cost. If you repay more than the agreed amount, the lender may be left with funding it cannot use, and it passes that cost to you as a break fee. This is why fixed rate products come with annual extra repayment caps.
Annual Extra Repayment Limits on Fixed Rate Products
Fixed rate investment loans typically allow between $10,000 and $30,000 in extra repayments per year without penalty. Some lenders calculate this as a percentage of the original loan balance, while others use a flat dollar cap. The cap resets each year during the fixed period.
If you repay above the cap, you will be charged a break cost. This cost is calculated based on the difference between the rate you fixed at and the current wholesale rate your lender can access. If rates have risen since you fixed, the break cost is usually zero or minimal. If rates have fallen, the break cost can be substantial.

How Break Costs Are Calculated
Break costs are not a flat fee. They depend on how much you are repaying above the cap, how much time remains on your fixed term, and the movement in wholesale interest rates since you locked in. Lenders use an economic cost calculation that compares what they are losing by allowing you to exit the fixed arrangement early.
Consider an investor who fixed a loan of $400,000 at 5.2% for three years. After 18 months, they decide to sell the property and repay the full loan. At the time of the sale, rates have dropped and the lender can only reinvest that money at 4.5%. The lender calculates the economic loss over the remaining 18 months and charges that amount as a break cost. In this scenario, the break cost could be $4,000 to $6,000 depending on the lender's formula.
If rates had increased instead, the lender can reinvest the repaid funds at a higher rate than the original fixed rate, so there is no economic loss and no break cost.
Split Loan Structures for Flexibility
Splitting your investment loan between fixed and variable portions gives you access to both rate certainty and repayment flexibility. A common split is 50% fixed and 50% variable, but the ratio can be adjusted to suit your borrowing strategy.
The variable portion allows unlimited extra repayments without penalty, and you can redraw those funds later if needed. The fixed portion protects you from rate rises during that period. For investors in Eagleby who expect irregular income from bonuses or business distributions, a split structure means you can put extra funds toward the loan without triggering break costs, while still holding a portion of the debt at a fixed rate.
When Fixed Rates Make Sense for Investors
Fixed rates suit investors who want certainty over their holding costs, particularly if rental income only just covers the loan repayment. Locking in your rate means you know exactly what your repayment will be for the fixed period, which makes budgeting and cash flow forecasting more predictable.
Eagleby has a rental vacancy rate that fluctuates with the broader Logan region. During periods of higher vacancy, having a fixed rate means your repayment will not increase even if the Reserve Bank raises rates. That certainty can be the difference between holding the property through a vacant period or being forced to sell.
Fixed rates are less suited to investors who plan to sell within the fixed period, or who expect to make large lump sum repayments from business income or other asset sales. In those cases, a variable rate or split structure offers more flexibility.
What Happens When Your Fixed Rate Expires
When your fixed term ends, your loan automatically reverts to the lender's standard variable rate unless you take action. Standard variable rates are typically higher than discounted variable rates, so this is the time to refinance your investment loan or negotiate a new rate with your current lender.
Most lenders allow you to refix, switch to a discounted variable rate, or move to another lender without penalty once the fixed term has ended. This is also the time to reassess whether you want to maintain interest-only repayments or switch to principal and interest, depending on your tax position and portfolio strategy.
If you are holding multiple properties, the end of a fixed term is an opportunity to restructure your loans and potentially release equity for your next purchase. Speak to a mortgage broker in Eagleby before your fixed term expires so you have time to compare investment loan options and lock in a new rate before reverting to a higher standard variable rate.
Interest-Only Fixed Rates and Repayment Flexibility
Many investment loans are structured as interest-only for the first one to five years, and this can be combined with a fixed rate. During the interest-only period, your required repayment only covers the interest charged each month, which maximises your tax deductions and keeps your cash flow flexible.
Even on an interest-only fixed rate loan, you can usually make extra repayments up to the annual cap. Those extra repayments reduce the principal balance, which means less interest is charged. However, because the loan is interest-only, you may not be required to continue making those higher repayments, and some lenders allow redraws on interest-only investment loans if the loan structure permits it.
Not all lenders allow redraw on interest-only investment loans, and some distinguish between repayments made voluntarily and those required under the loan contract. Check your loan terms before assuming you can access extra repayments later.
Refinancing Before the Fixed Term Ends
If you want to refinance your investment loan before the fixed term expires, you will need to break the fixed rate contract, and break costs will apply if the economic cost calculation results in a loss for the lender. Some investors choose to refinance mid-term if they can access a significantly lower rate or better loan features elsewhere, but this only makes financial sense if the interest savings over the remaining loan term exceed the break cost.
Calculate the break cost with your current lender before making a decision. Most lenders will provide a break cost estimate over the phone or via online banking. Compare that figure against the interest rate reduction and any other benefits the new loan offers, such as a lower interest rate, offset account access, or higher borrowing capacity for your next purchase.

Frequently Asked Questions
Can I make extra repayments on a fixed rate investment loan?
Yes, most fixed rate investment loans allow extra repayments up to an annual cap, usually between $10,000 and $30,000. Exceeding the cap triggers break costs, which depend on interest rate movements and the time remaining on your fixed term.
What are break costs on a fixed investment loan?
Break costs are charged when you repay more than the allowed annual limit or refinance before the fixed term ends. The cost is calculated based on the lender's economic loss, which depends on how much rates have moved since you fixed your loan.
Should I fix my investment loan or keep it variable?
Fixed rates suit investors who want repayment certainty and expect to hold the property without making large extra repayments. Variable rates or split structures offer more flexibility if you plan to pay down the loan faster or refinance during the loan term.
What happens when my fixed rate investment loan expires?
Your loan automatically reverts to the lender's standard variable rate, which is typically higher than discounted variable rates. You can refinance, refix, or negotiate a new rate without penalty once the fixed term ends.
Can I split my investment loan between fixed and variable?
Yes, splitting your loan allows you to lock in part of your debt at a fixed rate while keeping the rest variable for flexible extra repayments. A common split is 50/50, but the ratio can be adjusted to suit your strategy.
