Calculator Assumptions and Disclaimers
What is a home loan calculator?
Also called a "mortgage calculator", a home loan calculator can help you to:
- Find a low rate: Work out the lowest interest rates you can afford, and how much you could save compared to a higher rate loan.
- Find out how much you can borrow: Use your income and saved deposit to work out how much you can afford to borrow and comfortably repay.
- Find out how much you’ll pay in interest: Break down the total cost of your loan, and see how much total interest you’ll pay when you buy a property.
Keep in mind that a mortgage calculator does not take every aspect of your personal situation into account, and is not a substitute for professional financial advice.
When should I use a home loan calculator?
Home loan calculators can be useful at almost any stage of your home loan journey.
- Before you start looking for properties, you can estimate how much a bank may offer to lend you, giving you a better idea of your real estate budget.
- When you’re seeking home loan preapproval, you can determine the maximum repayments you could potentially afford, and how this could change if interest rates were to rise or fall.
- When making offers on properties, you can determine how different purchase prices and property values can affect the LVR and LMI on your home loan.
- Once you have a home loan, you can work out how refinancing to a different interest rate could affect your repayments and potentially put you in a better financial position.
What type of calculator should I use when I’m looking to buy?
- Home loan repayment calculator: By using this calculator to estimate your mortgage repayments with different variables, you can work out which loans match your needs and financial situation.
- Borrowing power calculator: This calculator can help you determine how much money a lender may offer to lend you when you’re seeking pre-approval, so you can have a maximum budget in mind when making an offer on a new home or investment property.

Why should I use a mortgage calculator?
Mortgage calculators, such as those found on RateCity, can help you quickly and easily compare the costs and benefits of home loans in Australia from a variety of different mortgage lenders – simply enter the details of each offer to estimate its overall value. Knowing the monthly (or weekly or fortnightly) repayments on a home loan can also help you estimate the total cost over the full loan term.
Useful for anyone considering buying a home, a home loan calculator can offer a way to understand your future financial outlook, whether you're a first home buyer, you've bought before, or you’re buying an investment property.
Will using a bank or lender's calculator offer the best results?
Using a bank’s home loan calculator, such as those from the Commonwealth Bank, ANZ, NAB, Westpac, or another major lender, may help you estimate the cost of repayments for that bank’s own mortgage products, which can be handy if you’re looking for a home loan from a specific bank or lender.
However, a bank’s mortgage calculators may not always let you adjust the figures in your calculation (e.g. the interest rate, loan term etc.) to something other than what’s offered by their own loan products, preventing you from being able to easily see how each factor may affect the loan. Plus, there may not be an easy way to compare the calculated cost of the bank’s mortgage offers to the value of home loans from other mortgage lenders.
What a home loan comparison calculator offers
A mortgage calculator from a home loan comparison site may allow you to enter your own interest rate, loan term and more, giving you more control over your calculations, and a greater understanding of which home loan features and benefits may affect the final cost and value.
You can also quickly compare the results from the calculator on a comparison site with other home loan offers from other banks and lenders. This can help you find alternative home financing options, perhaps even with a mortgage lender you hadn’t previously considered.
How do I use a home loan repayment calculator?
To find the estimated repayments on a home loan, simply enter a few details into our home loan calculator:
- The loan amount you’d like to borrow
- The interest rate you’d like to pay
- Your preferred repayment type e.g. Principal and Interest or Interest Only
- Your borrower type e.g. Owner Occupier or Investor
- The loan term you’d like to take to pay off your debt
Using this information, we can calculate:
- Your estimated repayments (weekly, monthly, or fortnightly)
- The total interest payable
- The total amount payable
- Your repayment schedule
Our calculator can also show you how much you could potentially save by adjusting your loan term or other figures, and help you compare home loans that may suit the requirements you’ve entered.
How do I view my mortgage calculator repayment schedule?
If you click to view your repayment schedule in your mortgage calculator results, you’ll be shown a graph illustrating how your mortgage can be paid off over time. You can see at a glance how much of each home loan repayment will be made up of your loan’s principal, how much will be made up of interest charges, and how these percentages will change over time as you pay off your loan.
You can also click to view your repayment schedule as a table, showing a full breakdown of the dollar values that make up each repayment. This can be handy if you like to precisely manage your household budget, or want to get a better idea of exactly where your money will be going.
Keep in mind that your repayment schedule is an estimate based on the values entered into the mortgage calculator. It does not take into account:
- increases or decreases to variable interest rates
- any fees you may be charged
- the use of loan features such as an offset account or redraw facility

What's the next step after using a mortgage calculator?
After the mortgage repayment calculator has told you how much you could expect to pay for your home loan, the next step is to compare the range of home loans that are available on the market, and to consider their interest rates, fees, features and other benefits, such as offset and redraw, and whether or not the loan product offers a fixed rate or variable rate. These loan products can vary wildly, and there may also be other eligibility criteria or lending criteria for you to fulfil when you’re home buying.
Keep in mind that as well as interest, there may be upfront and ongoing fees and other charges to consider. To get a better idea of a home loan’s overall cost, look at its comparison rate. A mortgage’s interest and standard fees and charges are included when calculating its comparison rate, so you can tell at a glance which loans could end up costing more or less. Just remember that home loan comparison rates are calculated using pre-set assumptions for consistency – different terms will likely apply to your loan, so the comparison rate should provide a guideline only.
Will a mortgage broker make it easier than doing it myself?
Once you find a loan that may match your needs, you can contact the lender directly to make an application. If you’re having trouble working out which mortgage offer may be right for you, a mortgage broker may be able to provide personal financial advice.
Mortgage brokers are home loan experts who can help you with every step of searching and applying for a mortgage. A broker can look at your finances and personal goals, and calculate what repayments may best suit your budget, including the effect of making extra repayments or using home loan features such as offset or redraw.
Brokers can help you choose from home loan products that may suit your needs, including special mortgage deals that are exclusive to brokers. A mortgage broker can even help you manage the home loan application paperwork, saving you time and hassle.

Frequently asked questions
How does a mortgage calculator work?
A mortgage calculator is an extremely helpful tool when planning to take out a home loan and working out the costs. Although each mortgage calculator you come across may be slightly different, most will help you estimate how much your repayments will be. The calculator will often also show you the difference in repayments if you repay weekly, monthly or fortnightly.
To calculate these figures, you’ll be asked to enter a few details. These include the amount you plan to borrow, whether you’re an owner-occupier or an investor, the proposed interest rate and the home loan term. It will also often show you the total interest you’ll be charged and the total amount you’ll repay over the life of the loan.
Understanding how the mortgage calculator works, helps you to use it to see how different loan amounts, interest rates and terms affect your repayments. This can then help you choose a home loan that you can repay comfortably and save on interest costs. The mortgage calculator lets you compare the benefits and costs of home loans from different lenders to help you make a more informed choice. Use a mortgage calculator to help identify which home loan is most suitable for your requirements and financial situation.
How can I calculate interest on my home loan?
You can calculate the total interest you will pay over the life of your loan by using a mortgage calculator. The calculator will estimate your repayments based on the amount you want to borrow, the interest rate, the length of your loan, whether you are an owner-occupier or an investor and whether you plan to pay ‘principal and interest’ or ‘interest-only’.
If you are buying a new home, the calculator will also help you work out how much you’ll need to pay in stamp duty and other related costs.
How do you calculate how much you could save with a lower rate?
To work out how much you could save, we run the home loan details you’ve provided through our database, and search for similar home loan options that we think would be suitable for you.
We then calculate the costs of these loan options over 15 years (to keep our calculations consistent) and compare them to the cost calculations for your current home loan.
How much money can I borrow for a home loan?
Tip: You can use RateCity how much can I borrow calculator to get a quick answer.
How much money you can borrow for a home loan will depend on a number of factors including your employment status, your income (and your partner’s income if you are taking out a joint loan), the size of your deposit, your living expenses and any other debt you might hold, including credit cards.
A good place to start is to work out how much you can afford to make in monthly repayments, factoring in a buffer of at least 2 – 3 per cent to allow for interest rate rises along the way. You’ll also need to factor in additional costs that come with purchasing a property such as stamp duty, legal fees, building inspections, strata or council fees.
If you are planning on renting the property, you can factor in the expected rental income to help offset the mortgage, but again it’s prudent to add a significant buffer to allow for rental management fees, maintenance costs and short periods of no rental income when tenants move out. It’s also wise to factor in changes in personal circumstances – the typical home loan lasts for around 30 years and a lot can happen between now and then.
How do I apply for a home improvement loan?
When you want to renovate your home, you may need to take out a loan to cover the costs. You could apply for a home improvement loan, which is a personal loan that you use to cover the costs of your home renovations. There is no difference between applying for this type of home improvement loan and applying for a standard personal loan. It would be best to check and compare the features, fees and details of the loan before applying.
Besides taking out a home improvement loan, you could also:
- Use the equity in your house: Equity is the difference between your property’s value and the amount you still owe on your home loan. You may be able to access this equity by refinancing your home loan and then using it to finance your home improvement. Speak with your lender or a mortgage broker about accessing your equity.
- Utilise the redraw facility of your home loan: Check whether the existing home loan has a redraw facility. A redraw facility allows you to access additional funds you’ve repaid into your home loan. Some lenders offer this on variable rate home loans but not on fixed. If this option is available to you, contact your lender to discuss how to access it.
- Apply for a construction loan: A construction loan is typically used when constructing a new property but can also be used as a home renovation loan. You may find that a construction loan is a suitable option as it enables you to draw funds as your renovation project progresses. You can compare construction home loans online or speak to a mortgage broker about taking out such a loan.
- Look into government grants: Check whether there are any government grants offered when you need the funds and whether you qualify. Initiatives like the HomeBuilder Grant were offered by the Federal Government for a limited period until April 2021. They could help fund your renovations either in full or just partially.
Can I take a personal loan after a home loan?
Are you struggling to pay the deposit for your dream home? A personal loan can help you pay the deposit. The question that may arise in your mind is can I take a home loan after a personal loan, or can you take a personal loan at the same time as a home loan, as it is. The answer is that, yes, provided you can meet the general eligibility criteria for both a personal loan and a home loan, your application should be approved. Those eligibility criteria may include:
- Higher-income to show repayment capability for both the loans
- Clear credit history with no delays in bill payments or defaults on debts
- Zero or minimal current outstanding debt
- Some amount of savings
- Proven rent history will be positively perceived by the lenders
A personal loan after or during a home loan may impact serviceability, however, as the numbers can seriously add up. Every loan you avail of increases your monthly installments and the amount you use to repay the personal loan will be considered to lower the money available for the repayment of your home loan.
As to whether you can get a personal loan after your home loan, the answer is a very likely "yes", though it does come with a caveat: as long as you can show sufficient income to repay both the loans on time, you should be able to get that personal loan approved. A personal loan can also help to improve your credit score showing financial discipline and responsibility, which may benefit you with more favorable terms for your home loan.
How do you determine which home loan rates/products I’m shown?
When you check your home loan rate, you’ll supply some basic information about your current loan, including the amount owing on your mortgage and your current interest rate.
We’ll compare this information to the home loan options in the RateCity database and show you which home loan products you may be eligible to apply for.
How do I calculate monthly mortgage repayments?
Work out your mortgage repayments using a home loan calculator that takes into account your deposit size, property value and interest rate. This is divided by the loan term you choose (for example, there are 360 months in a 30-year mortgage) to determine the monthly repayments over this time frame.
Over the course of your loan, your monthly repayment amount will be affected by changes to your interest rate, plus any circumstances where you opt to pay interest-only for a period of time, instead of principal and interest.
What are the different types of home loan interest rates?
A home loan interest rate is used to calculate how much you’ll pay the lender, usually annually, above the amount you borrow. It’s what the lenders charge you for them lending you money and will impact the total amount you’ll pay over the life of your home loan.
Having understood what are home loan rates in general, here are the two types you usually have with a home loan:
These interest rates remain constant for a specific period and are a good option if you’re a first-time buyer or if you’re looking for a fixed monthly repayment. One possible downside of a fixed rate is that it may be higher than a variable rate. Also, you don’t benefit from any lowering of interest rates in the market. On the flip side, if rates go up, your rate won’t change, possibly saving you money.
With variable interest rates, the lender can change them at any time. This change can be based on economic conditions or other reasons. Changes in interest rates could be beneficial if your monthly repayment decreases but can be a problem if it increases. Variable interest rates offer several other benefits often not available with fixed rate home loans like redraw and offset facilities and free extra repayments.
How do I apply for Westpac’s first home buyer loan?
If you’re a first home buyer looking to apply for a home loan with Westpac, they offer an online home loan application. They suggest the application can be completed in about 20 minutes. Based on the information you provide, Westpac will advise you the amount you can borrow and the costs associated with any possible home loan.
When applying for a home loan with Westpac, you’re assigned a home finance manager who can address your concerns and provide information. The manager will also offer guidance on any government grants you may be eligible for.
Who has the best home loan?
Determining who has the ‘best’ home loan really does depend on your own personal circumstances and requirements. It may be tempting to judge a loan merely on the interest rate but there can be added value in the extras on offer, such as offset and redraw facilities, that aren’t available with all low rate loans.
To determine which loan is the best for you, think about whether you would prefer the consistency of a fixed loan or the flexibility and potential benefits of a variable loan. Then determine which features will be necessary throughout the life of your loan. Thirdly, consider how much you are willing to pay in fees for the loan you want. Once you find the perfect combination of these three elements you are on your way to determining the best loan for you.

What are the responsibilities of a mortgage broker?
Mortgage brokers act as the go-between for borrowers looking for a home loan and the lenders offering the loan. They offer personalised advice to help borrowers choose the right home loan for their needs.
In Australia, mortgage brokers are required by law to carry an Australian Credit License (ACL) if they offer credit assistance services. Which is the legal term for guidance regarding the different kinds of credit offered by lenders, including home loan mortgages. They may not need this license if they are working for an aggregator, for instance, as a franchisee. In both these situations, they need to comply with the regulations laid down by the Australian Securities and Investments Commission (ASIC).
These regulations, which are stipulated by Australian legislation, require mortgage brokers to comply with what are called “responsible lending” and “best interest” obligations. Responsible lending obligations mean brokers have to suggest “suitable” home loans. This means loans that you can easily qualify for, actually meet your needs, and don’t prove unnecessarily challenging for you.
Starting 1 January 2021, mortgage brokers must comply with best interest obligations in addition to responsible lending obligations. These require mortgage brokers to act in the best interest of their customers and also requires them to prioritise their customers’ interests over their own. For instance, a mortgage broker may not recommend a lender who gives them a commission if that lender’s home loan offer does not benefit that particular customer.
How to apply for a home loan pre-approval from St. George?
By applying for a home loan pre-approval, you can establish how much you can afford to borrow and look for houses within that pre-approved budget. Getting home loan pre-approval from St. George is a fairly simple process that can be completed within 15 minutes.
The first step in this process is completing a home loan application. Once that application is submitted, a home loan expert from St. George will contact you to understand your requirements and your current financial position. You could also directly contact a home loan expert at the bank by calling 13 33 30 or by visiting your nearest branch.
Once the application has been processed, the home loan expert will ask for some basic documentation to confirm your borrowing capacity. After this, you should be issued a home loan pre-approval, subject to certain conditions.
Based on your home loan pre-approval from St. George, you can then find a property and make an offer. Your home loan expert will arrange to have the property valued and may request for more documentation, taking your home loan application to the next step.
How do I refinance my home loan?
Refinancing your home loan can involve a bit of paperwork but if you are moving on to a lower rate, it can save you thousands of dollars in the long-run. The first step is finding another loan on the market that you think will save you money over time or offer features that your current loan does not have. Once you have selected a couple of loans you are interested in, compare them with your current loan to see if you will save money in the long term on interest rates and fees. Remember to factor in any break fees and set up fees when assessing the cost of switching.
Once you have decided on a new loan it is simply a matter of contacting your existing and future lender to get the new loan set up. Beware that some lenders will revert your loan back to a 25 or 30 year term when you refinance which may mean initial lower repayments but may cost you more in the long run.
