Mortgage calculators
If you're looking to find out how much you can borrow or what your mortgage repayments might be, you've come to the right place.
Banks will often let you borrow more money than you can actually afford. Our home loan experts will help to give you an idea of how much you can afford to borrow.
And if you're looking to work out what your repayment amounts might be, check out our mortgage repayments calculator - it's easy to see how your repayments change based on loan size, rate or loan term.

Our First Home Buyers Guide has everything you need to know
If you're planning on getting your foot in the door of the property market, everything you need to know about deposits, house prices and navigating the process is in our free digital guide.
Wondering about your deposit?
Basically, banks won't lend the full house price amount - you need to be able to put down a deposit, and the more the better. You may be familiar with 20% as the magic number, but the reality is if you're in a strong financial position we can work with as little as 5% deposit.
Calculating your borrowing power
A mortgage calculator is a good place to start when starting to think about how much you can borrow. But there are lots of factors that come into play, and every situation is different. Here are a few things to consider.
Get schooled up so you can make smarter decisions.
The more you understand about borrowing for a house, the more likely you will be to make more informed decisions that work for you. We've written a few articles that we think you'll find helpful.

We were really happy with the advice and service we recieved from Tasmania. Of note was the advice around staying on the floating rate prior to the OCR announcement, saving us thousands off our mortgage so wo lock in the lower rate. Tas was great in following up with us on what we needed to get in and timelines and we would use and recommend him in the future.
