Mortgage repayment calculators

Mortgage repayment calculators

Mortgage repayments are the payments you make back to the financial institution that lent you money to purchase your home. The mortgage repayments are stated in your contract, and are calculated based on the total loan amount divided by the term, plus interest and other fees. These are usually paid on a weekly, fortnightly or monthly basis. Each payment made is debited from your outstanding debt, so with each payment you are a step closer to owning your investment or home.

Mortgage repayment calculators

Mortgage repayment calculators are a great tool to use to work out exactly what your weekly, fortnightly or monthly repayments will look like. If you have a few home loans in mind, add in their interest rates and term loans and it will calculate a repayment amount for you.

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.

How much are repayments on a $250K mortgage?

The exact repayment amount for a $250,000 mortgage will be determined by several factors including your deposit size, interest rate and the type of loan. It is best to use a mortgage calculator to determine your actual repayment size.

For example, the monthly repayments on a $250,000 loan with a 5 per cent interest rate over 30 years will be $1342. For a loan of $300,000 on the same rate and loan term, the monthly repayments will be $1610 and for a $500,000 loan, the monthly repayments will be $2684.

Remaining loan term

The length of time it will take to pay off your current home loan, based on the currently-entered mortgage balance, monthly repayment and interest rate.

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 can I pay off my home loan faster?

The quickest way to pay off your home loan is to make regular extra contributions in addition to your monthly repayments to pay down the principal as fast as possible. This in turn reduces the amount of interest paid overall and shortens the length of the loan.

Another option may be to increase the frequency of your payments to fortnightly or weekly, rather than monthly, which may then reduce the amount of interest you are charged, depending on how your lender calculates repayments.

What are extra repayments?

Additional payments to your home loan above the minimum monthly instalments, which can help to reduce the loan’s term and remaining payable interest.

What is an interest-only loan? How do I work out interest-only loan repayments?

An ‘interest-only’ loan is a loan where the borrower is only required to pay back the interest on the loan. Typically, banks will only let lenders do this for a fixed period of time – often five years – however some lenders will be happy to extend this.

Interest-only loans are popular with investors who aren’t keen on putting a lot of capital into their investment property. It is also a handy feature for people who need to reduce their mortgage repayments for a short period of time while they are travelling overseas, or taking time off to look after a new family member, for example.

While moving on to interest-only will make your monthly repayments cheaper, ultimately, you will end up paying your bank thousands of dollars extra in interest to make up for the time where you weren’t paying off the principal.

What happens to my home loan when interest rates rise?

If you are on a variable rate home loan, every so often your rate will be subject to increases and decreases. Rate changes are determined by your lender, not the Reserve Bank of Australia, however often when the RBA changes the cash rate, a number of banks will follow suit, at least to some extent. You can use RateCity cash rate to check how the latest interest rate change affected your mortgage interest rate.

When your rate rises, you will be required to pay your bank more each month in mortgage repayments. Similarly, if your interest rate is cut, then your monthly repayments will decrease. Your lender will notify you of what your new repayments will be, although you can do the calculations yourself, and compare other home loan rates using our mortgage calculator.

There is no way of conclusively predicting when interest rates will go up or down on home loans so if you prefer a more stable approach consider opting for a fixed rate loan.

What is a fixed home loan?

A fixed rate home loan is a loan where the interest rate is set for a certain amount of time, usually between one and 15 years. The advantage of a fixed rate is that you know exactly how much your repayments will be for the duration of the fixed term. There are some disadvantages to fixing that you need to be aware of. Some products won’t let you make extra repayments, or offer tools such as an offset account to help you reduce your interest, while others will charge a significant break fee if you decide to terminate the loan before the fixed period finishes.

What is 'principal and interest'?

‘Principal and interest’ loans are the most common type of home loans on the market. The principal part of the loan is the initial sum lent to the customer and the interest is the money paid on top of this, at the agreed interest rate, until the end of the loan.

By reducing the principal amount, the total of interest charged will also become smaller until eventually the debt is paid off in full.

What happens when you default on your mortgage?

A mortgage default occurs when you are 90 days or more behind on your mortgage repayments. Late repayments will often incur a late fee on top of the amount owed which will continue to gather interest along with the remaining principal amount.

If you do default on a mortgage repayment you should try and catch up in next month’s payment. If this isn’t possible, and missing payments is going to become a regular issue, you need to contact your lender as soon as possible to organise an alternative payment schedule and discuss further options.

You may also want to talk to a financial counsellor. 

What is mortgage stress?

Mortgage stress is when you don’t have enough income to comfortably meet your monthly mortgage repayments and maintain your lifestyle. Many experts believe that mortgage stress starts when you are spending 30 per cent or more of your pre-tax income on mortgage repayments.

Mortgage stress can lead to people defaulting on their loans which can have serious long term repercussions.

The best way to avoid mortgage stress is to include at least a 2 – 3 per cent buffer in your estimated monthly repayments. If you could still make your monthly repayments comfortably at a rate of up to 8 or 9 per cent then you should be in good position to meet your obligations. If you think that a rate rise would leave you at a risk of defaulting on your loan, consider borrowing less money.

If you do find yourself in mortgage stress, talk to your bank about ways to potentially reduce your mortgage burden. Contacting a financial counsellor can also be a good idea. You can locate a free counselling service in your state by calling the national hotline: 1800 007 007 or visiting www.financialcounsellingaustralia.org.au.

How long should I have my mortgage for?

The standard length of a mortgage is between 25-30 years however they can be as long as 40 years and as few as one. There is a benefit to having a shorter mortgage as the faster you pay off the amount you owe, the less you’ll pay your bank in interest.

Of course, shorter mortgages will require higher monthly payments so plug the numbers into a mortgage calculator to find out how many years you can potentially shave off your budget.

For example monthly repayments on a $500,000 over 25 years with an interest rate of 5% are $2923. On the same loan with the same interest rate over 30 years repayments would be $2684 a month. At first blush, the 30 year mortgage sounds great with significantly lower monthly repayments but remember, stretching your loan out by an extra five years will see you hand over $89,396 in interest repayments to your bank.
