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.

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.

When should I refinance my mortgage?

By John Bolton

Refinancing hasn't always been a super popular option among Kiwi borrowers, put off by all the admin involved. But the benefits—like cashbacks and the chance to restructure your mortgage and other debts to get them working better for you—could mean it's well worthwhile. Here's what you need to know.

Rodney's Ravings: High unemployment isn’t the constraint on economic growth some would have you think

By Rodney Dickens

It's your classic chicken and egg conundrum, with an economic twist: which came first—rising unemployment or New Zealand's slow economic recovery? While some have blamed a weak labour market for the sluggish state of the economy, Rodney Dickens (and the data) says it's actually the opposite.

We've worked with Ange and the team at Squirrel more than once now, and every time they've been absolutely fantastic. This time was no different, they looked after us from start to finish with the same professionalism, attention to detail, and just the right amount of hustle behind the scenes to make everything run smoothly. What I appreciate most is how they take the stress out of the process. I just tell them what we're trying to do, and they take care of the rest: crunching the numbers, dealing with the bank, and coming back with a clear plan. It means we can focus on the bigger picture without getting bogged down in the details. Even with a few curveballs from the bank this time, Ange and her team kept everything on track and moving forward. We managed to get both the sale and the purchase done without any delays or issues, which is exactly what you want in these situations. When we think about getting a loan, we think about Ange and the team, and no one else. I genuinely don't want to deal with any other company. They've earned that level of trust.

Sudam was great to deal with. I had already met with another broker and hadn't been happy with the interaction. Sudam's approach was completely different - he was really nice to talk to, very clear about the options and process, and made the whole thing easy for us. Sudam communicated well throughout and we're very happy with the outcome of switching our mortgage.
