Mortgage Calculator, Repayment Type
Will you pay off the amount you borrowed + interest or just the interest for a period?
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.
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 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 is the best interest rate for a mortgage?
The fastest way to find out what the lowest interest rates on the market are is to use a comparison website.
While a low interest rate is highly preferable, it is not the only factor that will determine whether a particular loan is right for you.
Loans with low interest rates can often include hidden catches, such as high fees or a period of low rates which jumps up after the introductory period has ended.
To work out the best value for money, have a look at a loan’s comparison rate and read the fine print to get across all the fees and charges that you could be theoretically charged over the life of the loan.
Your current home loan interest rate. To accurately calculate how much you could save, an accurate interest figure is required. If you are not certain, check your bank statement or log into your mortgage account.
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.
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.
