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.

*This calculator is intended as a guide for illustrative purposes only and is not intended to provide financial advice. The results are based on the information you enter and assume that interest rates and loan terms remain constant for the duration of the loan. It does not account for fees, fluctuating interest rates, or changes to your financial situation over time. Please note that actual repayment amounts may differ and interest rates are subject to change. To talk to one of our team at Squirrel, contact us here.

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.

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!
