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. We’ll help to give you an idea of how much you can afford to borrow.
And if you are looking to work out what your repayments might be, check out our mortgage repayments calculator.

It does not account for fees, fluctuating interest rates, or changes to your financial situation over time.

Wondering about your deposit?
Basically, banks won't lend the full amount for a house - 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

OCR & interest rates update – July 2025
The RBNZ has hit a temporary pause on rate cuts, holding the OCR at 3.25% on 9th July—and leaving us hanging just a fraction above neutral. It's the outcome the market was broadly expecting, but was it the right call? Not according to Squirrel founder, JB.

Rodney’s Ravings: Things aren’t as gloomy as card spending data suggests
Stats NZ's monthly card spending data is often seen as an indicator of economic health—and if the latest numbers are anything to go by, we're a country still deep in recession. But card spending data only represents one part of the equation, says Rodney Dickens, and the reality is things aren't as bad as they first appear.

My partner and I were looking to purchase our first home, we had no idea what we were doing and the amount of information we were accessing seemed very overwhelming. We made some enquiries about brokers, made an website and were put in touch with Basil. He simplified the process right down for us, was available every step of the way and after a number of false starts, we moved into our new home yesterday. Couldn't recommend these guys more. Especially Basil, who I am now referring to anyone who I know is looking to start their home ownership journey.

Our advisor was knowledgeable and good at explaining the options. At what can be a quite a stressful time (making a property transaction), he brought patience and clarity which helped us achieve what we wanted to achieve. We are very happy with the result. Thanks Squirrel!
