What is a home loan calculator?

Also called a "mortgage calculator" or a "home loan deposit 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.

How to use a home loan calculator

To find the estimated repayments on a home loan, simply enter a few details into our home loan calculator:

  • How much 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

Why should I use a mortgage calculator?

Using a mortgage calculator at a comparison site such as RateCity may help you estimate the costs and benefits of a wider variety of loan choices, and gain a deeper understanding of how a new home loan’s features can affect its overall value. 

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. 

Useful for anyone considering buying a home, a home loan calculator can be an ideal way to understand what your financial outlook will look like whether you've bought before, buying an investment property, or if you're a first home buyer, and want an outlook the repayment amount over the course of a loan's life, be it through monthly repayments or another term.

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 its own mortgage products, which can be handy if you’re looking at a specific home loan from a specific bank or lender. 

However, bank mortgage calculators may not always let you adjust the figures in your calculation (e.g. the interest rate, loan term etc.), preventing you from being able to see how each 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. 

On the other hand, 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 the loans you can apply for. This can help give you a better idea of which home loan features and benefits may affect each home loan’s final cost and value.

What type of calculator should I use when I’m looking to buy?

Much like home loans, mortgage calculators aren’t one-size-fits-all, and there are many options to choose from. 

If you’re starting out, you may want to use a borrowing power calculator, which will help you determine how much money you can expect to take out ahead of pre-approval. You can use this number to gauge how much you think you can afford, and apply that as you search for a home. 

A broker may be able to help maximise your borrowing power, but this is a solid first step to working out what you can spend. 

If you’re closer to buying, a Lender’s Mortgage Insurance calculator will help provide a gauge on how much LMI you might be up for on a property, while a Stamp Duty Calculator assists in understanding any stamp duty you may have to pay on a property.

If you're perhaps in the market to refinance rather than buy outright, you may want to consider a refinance calculator instead, as it may deliver a more useful outcome, working out what interest repayments look like from one loan, your current loan, and potentially switching to another.

After this, consider the calculator on this page, the standard Home Loan Calculator, which provides a more firm understanding of what you can expect to pay for a new home. Home loan calculators, such as RateCity’s mortgage calculator, provide a way of working out which loans match your needs and financial situation, ordered by variables that matter most to you. 

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.

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

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 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 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 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:

  1. 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.
  2. 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.
  3. 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.
  4. 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.  

Cash or mortgage – which is more suitable to buy an investment property?

Deciding whether to buy an investment property with cash or a mortgage is a matter or personal choice and will often depend on your financial situation. Using cash may seem logical if you have the money in reserve and it can allow you to later use the equity in your home. However, there may be other factors to think about, such as whether there are other debts to pay down and whether it will tie up all of your spare cash. Again, it’s a personal choice and may be worth seeking personal advice.

A mortgage is a popular option for people who don’t have enough cash in the bank to pay for an investment property. Sometimes when you take out a mortgage you can offset your loan interest against the rental income you may earn. The rental income can also help to pay down the loan.

When does Commonwealth Bank charge an early exit fee?

When you take out a fixed interest home loan with the Commonwealth Bank, you’re able to lock the interest for a particular period. If the rates change during this period, your repayments remain unchanged. If you break the loan during the fixed interest period, you’ll have to pay the Commonwealth Bank home loan early exit fee and an administrative fee.

The Early Repayment Adjustment (ERA) and Administrative fees are applicable in the following instances:

  • If you switch your loan from fixed interest to variable rate
  • When you apply for a top-up home loan
  • If you repay over and above the annual threshold limit, which is $10,000 per year during the fixed interest period
  • When you prepay the entire outstanding loan balance before the end of the fixed interest duration.

The fee calculation depends on the interest rates, the amount you’ve repaid and the loan size. You can contact the lender to understand more about what you may have to pay. 

What are the features of home loans for expats from Westpac?

If you’re an Australian citizen living and working abroad, you can borrow to buy a property in Australia. With a Westpac non-resident home loan, you can borrow up to 80 per cent of the property value to purchase a property whilst living overseas. The minimum loan amount for these loans is $25,000, with a maximum loan term of 30 years.

The interest rates and other fees for Westpac non-resident home loans are the same as regular home loans offered to borrowers living in Australia. You’ll have to submit proof of income, six-month bank statements, an employment letter, and your last two payslips. You may also be required to submit a copy of your passport and visa that shows you’re allowed to live and work abroad.

What do people do with a Macquarie Bank reverse?

There are a number of ways people use a Macquarie Bank reverse mortgage. Below are some reasons borrowers tend to release their home’s equity via a reverse mortgage:

  • To top up superannuation or pension income to pay for monthly bills;
  • To consolidate and repay high-interest debt like credit cards or personal loans;
  • To fund renovations, repairs or upgrades to their home
  • To help your children or grandkids through financial difficulties. 

While there are no limitations on how you can use a Macquarie reverse mortgage loan, a reverse mortgage is not right for all borrowers. Reverse mortgages compound the interest, which means you end up paying interest on your interest. They can also affect your entitlement to things like the pension It’s important to think carefully, read up and speak with your family before you apply for a reverse mortgage.

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.

Can first home buyers apply for an ING home loan?

First home buyers can apply for an ING home loan, but first, they need to select the most suitable home loan product and calculate the initial deposit on their home loan. 

First-time buyers can also use ING’s online tool to estimate the amount they can borrow. ING offers home loan applicants a free property report to look up property value estimates.

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.

Is a home equity loan secured or unsecured?

Home equity is the difference between its current market price and the outstanding balance on the mortgage loan. The amount you can borrow against the equity in your property is known as a home equity loan.

A home equity loan is secured against your property. It means the lender can recoup your property if you default on the repayments. A secured home equity loan is available at a competitive rate of interest and may be repaid over the long-term. Although a home equity loan is secured, lenders will assess your income, expenses, and other liabilities before approving your application. You’ll also want  a good credit score to qualify for a home equity loan.
