How Much Can I Borrow?
You could borrow
$390,000 – $440,000
A purchase budget of about $550,000 with your deposit.
First-home buyers, two adults' living costs, $450 a month of other debts, tested at 7%. Estimate only.
A visitor working out their repayments or how much they could borrow is close to a decision. Give them the answer on your website and the next conversation is with you.
People run a mortgage calculator when they are weighing up a move: a first home, a refix, a refinance. Those are the enquiries you want.
Each calculator carries your logo, your colours and your contact details, so the result and the adviser arrive together.
When a result lands, the calculator tells your page, so your own enquiry form or booking link can follow it. We never collect their details for you.

How much could I borrow for my first home?
Tests income, living costs and deposit against the three limits a New Zealand lender applies, and shows which one holds you back.
Shows: A borrowing range and purchase budget from your income, costs and deposit, and which of the three lender limits - repayments, 6x income or deposit - decides it.
Am I on the best deal?
Compares your mortgage today with a switch to today's rate for your fixed term, plus an offset account working for you.
Shows: Your loan today against a switch to today's rate for your fixed term, and an optimal solution that keeps your repayment and puts the difference, cashback and everyday balance into an offset: interest and time saved, a comparison table and the balance over time.
What are the banks charging today?
Each lender's lowest published home-loan rate for every fixed term, refreshed hourly, with the lowest in each term highlighted.
Shows: Published New Zealand home loan rates by lender and fixed term, with the lowest in each term marked.
Which lender and loan structure costs the least?
For advisers: compares a standard split against an offset structure at each lender and finds the offset amount that keeps interest lowest.
Shows: A standard mortgage against an offset structure at each lender, with the offset amount that keeps interest lowest.
Your future clients are already working out what they can afford, late at night, on somebody's website. This film follows that moment: where it happens today, what the research says makes a calculator get used, and what it means for your own website.

A useful calculator keeps visitors on your website instead of sending them to a bank or a comparison site.
Accurate, well-designed tools in your branding show clients you know your numbers.
Clients arrive knowing their borrowing range, repayments and options, so meetings start further along.
