What is a comparison rate in home loans, and should you pay attention to it? Yes. A comparison rate combines the advertised interest rate with certain standard fees and charges. It gives you a clearer view of the potential cost of a house loan. Think of the interest rate as the price in the shop window. The comparison rate is closer to the price at the checkout. It is not a perfect measure, but it can help you spot a home loan that looks cheap until the fees arrive. Before choosing between CommBank, NAB, Westpac, ANZ, Macquarie, ING or another lender, it pays to compare both numbers.
What Is a Comparison Rate in Home Loans?
A comparison rate is a single percentage that combines a loan’s interest rate with most of its standard fees and charges. It is designed to make home loan comparison easier. Instead of checking the advertised rate and then hunting through pages of fees, you receive one percentage that gives you a broader view of the loan’s cost.
For example, a lender may advertise a home loan interest rate of 5.80% p.a. and a comparison rate of 6.05% p.a. The difference may reflect application fees, establishment costs, ongoing account fees and other standard charges. The Australian Securities and Investments Commission explains that comparison rates include the interest rate and most fees and charges. Their purpose is to show the cost of a credit product more clearly and make different loans easier to compare.
What Does a Comparison Rate in Home Loans Tell You?
A comparison rate tells you that the lowest advertised mortgage rate may not always lead to the lowest overall cost. If the comparison rate is close to the interest rate, the home loan may have relatively few standard fees. If there is a large gap between the two rates, the loan may carry higher upfront or ongoing costs. That gap is a prompt to investigate. It is not automatic proof that the loan is poor value.
A mortgage with a higher fee may include a useful feature, such as an offset account, that could save the right borrower far more than the fee. Another loan may have a wonderfully low rate but lack the flexibility you need.
In my view, the comparison rate is best treated as an early warning system. It tells you where to look, but it should not make the whole decision for you.
Why Is the Comparison Rate in Home Loans Usually Higher?
A home loan interest rate measures the interest charged on the money you borrow. It does not normally show the full range of standard loan fees. A comparison rate adds eligible fees and charges to that interest cost. That is why it will often be higher than the advertised interest rate. If the interest rate and comparison rate are almost identical, there may be few standard fees included. If the comparison rate is noticeably higher, ask the lender or mortgage broker what is creating the difference.
Comparison Rate Versus Interest Rate: What Is the Difference?
The difference is simple but important. The interest rate is the percentage a bank or lender charges on your outstanding home loan balance. It affects your regular mortgage repayments and the amount of interest you may pay over time.
The comparison rate includes that interest rate plus most standard fees and charges associated with the loan. It tries to express those combined costs as one annual percentage.
Imagine two home loans.
Loan A has an interest rate of 5.75% and a comparison rate of 6.10%. Loan B has an interest rate of 5.85% and a comparison rate of 5.92%.
In this scenario Loan A wins the attention contest because its advertised interest rate is lower. Loan B, however, may have lower standard fees and could be cheaper under the comparison-rate assumptions.
That is the slightly frustrating part of mortgage shopping: the smallest headline number does not always reveal the best deal.
What Is Included in a Home Loan Comparison Rate?
A home loan comparison rate generally includes the advertised interest rate and most standard fees that apply to the loan. These can include an application or establishment fee charged when the mortgage begins. They can also include lender settlement fees, monthly or annual account-keeping fees and certain discharge fees.
The exact costs included will depend on the loan. Always review the lender’s fee schedule, product disclosure material and loan documents before applying.
NAB’s comparison-rate guide confirms that a comparison rate can include application, settlement, ongoing account-keeping and discharge fees.
What Is Not Included in a Home Loan Comparison Rate?
A comparison rate does not include every possible mortgage cost. Government charges such as stamp duty and mortgage registration fees are generally excluded. Lenders mortgage insurance may also be excluded, along with fees triggered only in certain situations.
These conditional costs can include late-payment charges, some redraw fees and early repayment costs. The savings created by an offset account, redraw facility, fee waiver or package benefit are not reflected either. This matters because loan features can change the value you receive.
A borrower who keeps substantial savings in an offset account may reduce their interest costs. Another borrower may value unlimited extra repayments or free redraw. Those benefits may make a home loan more suitable even when its comparison rate is slightly higher.
CommBank’s explanation similarly notes that government charges, optional-feature costs, conditional fees and savings from interest-offset arrangements may not be included.
How Is a Comparison Rate in Home Loans Calculated?
Australian lenders use a regulated formula when calculating and advertising comparison rates for eligible consumer credit products.
For home loans, the displayed comparison rate is commonly calculated using a secured loan of $150,000 over a 25-year term.
This standard example gives borrowers a consistent starting point. However, it may look nothing like your actual mortgage.
If you borrow $700,000 over 30 years, your fees are spread across a much larger loan and a longer period. Your real cost may therefore differ from the advertised comparison rate.
Is a Comparison Rate in Home Loans Based on Your Actual Loan?
No. The advertised comparison rate is not a personalised quote.
It is based on the standard loan amount and term shown in the lender’s comparison-rate warning. Your actual loan amount, repayment type, loan term, interest rate, fees and features may be different.
This is one of the most important points to understand. A comparison rate is a guide, not a forecast of your exact borrowing cost.
Why Does the $150,000 Comparison Rate Example Matter?
Fixed fees have a stronger effect on a small loan than on a large one. Imagine a home loan with a $300 annual fee. That fee represents a greater share of a $150,000 mortgage than a $750,000 mortgage. As a result, the standard comparison rate may make some fees appear more influential than they would be on your actual loan.
The opposite can also happen. A feature that could save you money on a larger mortgage may not be captured at all. That is why it is wise to use both a home loan comparison rate and a mortgage repayment calculator.
Is the Lowest Comparison Rate Always the Best Home Loan?
Not necessarily. A low comparison rate can help you identify competitive home loans, but it only compares certain costs. It does not measure service, approval speed, borrowing capacity, loan flexibility or whether the lender’s credit policy suits you. It also does not place a dollar value on features that may be useful to you.
A first home buyer may want a simple house loan with low fees. A property investor may value an offset account and interest-only options. A self-employed borrower may need a lender that understands alternative income documents. The “best home loan” is not always the mortgage with the lowest interest rate or comparison rate. It is the loan that offers suitable features and a competitive total cost for your circumstances.
How Do You Compare Home Loan Rates Properly?
Start by comparing loans with the same purpose, repayment type and fixed or variable structure. An owner-occupier principal-and-interest home loan should not be compared directly with an investment or interest-only mortgage. They are priced and assessed differently.
Next, check both the interest rate and comparison rate. A large gap deserves a closer look, while a small gap may suggest lower standard fees.
Then consider the actual amount you plan to borrow. Use a mortgage calculator to estimate repayments for your loan size and preferred term rather than relying only on the standard $150,000 example.
Finally, review the features. Ask whether the home loan offers an offset account, redraw, extra repayments, a split-loan option or repayment flexibility. Check whether these features carry extra fees.
What Should You Ask Before Choosing a Mortgage?
Ask for the total upfront fees, ongoing fees and estimated repayments for your actual loan amount.
You should also ask whether the advertised rate is temporary, introductory or subject to conditions. Find out what happens when a fixed rate ends and whether the loan could revert to a higher variable rate.
If you plan to refinance, sell or repay the mortgage early, ask about discharge, switching and fixed-rate break costs.
One direct question can be especially useful: “What will this home loan cost me in dollars over the period I expect to keep it?”
That answer often feels far more real than a row of percentages.
What Does a Big Gap Between the Interest Rate and Comparison Rate Mean?
A large gap often indicates that the mortgage includes notable standard fees or that its pricing changes during the comparison period.
For example, an attractive introductory rate may later revert to a higher rate. A loan may also carry an application fee, annual package fee or monthly account charge.
Do not panic when you see a gap. Investigate it.
Read the fee schedule and ask the lender or broker to explain which costs are affecting the comparison rate. You may discover a fee-heavy loan, or you may find that the product includes features worth paying for.
How Can a Mortgage Calculator Help?
A mortgage repayment calculator turns a percentage into an estimated dollar amount.
You can enter your planned loan size, interest rate and loan term to see how repayments may change. You can also test different rates, terms and repayment frequencies.
For a better comparison, calculate the repayments for each home loan and then add its known upfront and ongoing fees. If an offset account matters to you, estimate the potential savings based on the amount you expect to keep in it.
The result will still be an estimate. However, it will be more relevant than relying on a standard comparison rate alone.
Frequently Asked Questions About Home Loan Comparison Rates
What is a comparison rate in simple terms?
A comparison rate is one percentage that combines a loan’s interest rate with most standard fees and charges. It helps borrowers compare the potential cost of different home loans.
Is a comparison rate the true cost of a home loan?
It is a useful guide to cost, but it is not a complete or personalised calculation. Some conditional fees, government charges and potential savings from loan features are excluded.
Is a lower comparison rate better?
A lower comparison rate may indicate a cheaper home loan under the standard calculation. You should still compare features, fees, loan terms and repayments based on your actual borrowing needs.
Why is my comparison rate higher than my interest rate?
The comparison rate is usually higher because it includes the interest rate plus most standard loan fees and charges.
Are all Australian home loan comparison rates calculated the same way?
Lenders must use the regulated comparison-rate formula for relevant advertised credit products. The displayed rate for a home loan is commonly based on a $150,000 secured loan over 25 years.
Does a comparison rate include an offset account?
A comparison rate does not normally account for the potential interest savings created by money held in an offset account. Fees charged for optional loan features may also be excluded.
Can I compare CommBank, NAB, Westpac and ANZ home loans using comparison rates?
Yes. Comparison rates can provide a useful starting point when comparing home loans from CommBank, NAB, Westpac, ANZ, Macquarie, ING and other Australian lenders. Make sure the loans have similar purposes, repayment types, terms and features. See our compare big four banks home loans page.
Compare the Real Cost Before You Choose
The advertised interest rate may grab your attention. The comparison rate helps you look behind the curtain. Neither number should be used alone. Compare the rate, standard fees, repayments, loan features and likely cost for the amount you want to borrow. A few minutes of careful home loan comparison now could save considerable frustration and money later.
