Home loan top-ups: understanding the basics
What is a home loan top-up?
Increasing, or ‘topping up’, your home loan is a way to access more funds by borrowing against your home’s equity – that is, the difference between our valuation of your home and the amount you owe on it.
How it works
Depending on how much equity you have and your financial situation, you can increase the size of your home loan up to 80% of its value to fund certain things.
How to grow your home’s equity
Your home’s value can increase just through rising house market prices. Other ways to build equity include paying off more of your home loan and increasing its value through renovations and improvements.

Things to consider
Before making the decision to apply for a home loan top-up there are a few things to consider.
Eligible home loans
Most of our variable home loan products are eligible for a top-up if you have equity available and you’re able to cover the increases in regular repayments. If you have a fixed interest rate, we recommend that you speak with one of our home loan expert to discuss your options.
How does a home loan top-up impact my repayments?
Following a home loan top-up, your regular repayments will increase. How much they increase depends on the size of the top-up. The more you borrow, the more your repayments will increase. You can use our home loans repayments calculator to generate an estimate of your future repayments.
Does a home loan top-up affect the length of my loan?
Topping up your home loan will not impact your loan term. If you would like to make changes to your loan term, your NAB home loan expert will be able to discuss your options with you.
How much can I increase my loan by?
Your home loan top-up is going to depend on a number of factors. We recommend that you speak to your NAB Home loan expert to discuss your options.
How do I request a home loan top-up?
The best way to request a home top up is to speak to one of our home loan expert. You can book an appointment at a time that suits you. However, if you got your home loan through a broker, it’s best to discuss your options directly with your broker or you can call us on 13 22 65.
Fees and charges
Home loan top-ups generally won’t attract any fees. One of our home loan expert will be able to discuss your options and let you know if there are any fees or charges
