Home loan repayments calculator

25 years

This mortgage calculator can be used to help you work out what your home loan repayments are going to be with different interest rates and home loan terms. With a home loan being such a major decision in life, it’s important to gather the most information possible to make an informed choice and to know what repayments you can afford.

How to use the home loan repayments calculator

To find out what your home loan repayments will be, you will need to enter some figures into the mortgage repayments calculator above. The simplified calculator requires the following three main details:

Loan amount: This is the amount of money remaining in your home loan. At the beginning of a new home loan, this could be up to 95% of the property’s value (or up to 110% if you are opting for a guarantor loan), but the amount will change as you pay off more of the loan and gain equity in your property. If you are refinancing, you may have a considerably smaller loan amount than you did at the start of your home loan.

Loan term (in years): Home loan terms tend to range between 20 – 40 years. The longer the term, the smaller the repayments will be. However, on the downside, the longer the term of your loan, the more interest you will pay.

Interest rate (% p.a.): This is the interest rate charged on your home loan. Higher interest rates tend to be charged for borrowers with more marks on their credit records, borrowing larger amounts, or paying smaller percentage deposits.

A simple calculation like this assumes no changes to the world around you, no changes in how you are paying your loan, and no changes in the loan’s conditions. Selecting the “advanced” dropdown will allow you to toggle many more options and get a more accurate picture of your repayments over the life of the loan. These extra options are:

Principal & Interest / Interest Only: Select whether the loan is principal & interest or interest only, which will make a big deal of difference to the size of your initial repayments and the time it will take you to pay off your loan.

Repayment frequency: This is how often you will be making your repayments. Most commonly, repayments are made monthly, but some lenders will allow flexible repayment schedules. This can mean fortnightly or weekly repayments if it better fits your schedule.

Introductory rate (% p.a.): If you have applied for a loan with an introductory rate, it’s important to enter it here. This can help to calculate how your repayments in the introductory period will differ from later repayments.

Introductory term (in years): Likewise, this is the length of time that your introductory interest rate applies for.

Upfront fee: Some home loans come with significant upfront fees, which will usually be worked into your repayments.

Ongoing fee: If your home loan has any kind of service fee or monthly payment, this is the place to enter it in. 

Fee frequency: If that service fee is monthly, here’s where you would say that. Otherwise, you might have some kind of ongoing yearly fee - you would note that here.

By putting in all the necessary figures, the calculator will put out your initial repayments (if you have an introductory offer or an interest only loan), your subsequent monthly repayments, and the total amount of interest you will pay for that home loan option.

You can also use this calculator to choose between different options and find the one that fits you best. You can do this by toggling the details in the calculator to match prospective loan details, like the interest rate.
