You Came Here With a Question. That Is Why This Exists.

Maybe you are a first home buyer trying to figure out what you can actually afford. Maybe you are staring at a tax return wondering what PAYE really means for your take-home pay. Maybe you just need a straight answer about GST, KiwiSaver, or how much your student loan repayments will be, and you do not want to pay someone to tell you.

That is exactly why Calculate.co.nz was built. Not as a business pitch. Not as a side hustle. As a belief, held for over fifteen years, that the information people need to make good financial decisions should be free, accurate, and available to everyone. Financial literacy is not a privilege reserved for the wealthy. It is a basic right that every New Zealander deserves, regardless of income or background.

Every calculator, every guide, every page on this site exists because someone, somewhere, typed a question into a search engine and deserved a clear answer without a paywall, a sales funnel, or a catch.

Where I Come From

I was born in the North East of England, a place with very little social mobility. My parents worked incredibly hard and instilled in me a strong work ethic and a drive to be better, and to help those around me. That has never left me. It is the foundation of everything I do.

Growing up in New Zealand offered much more opportunity, but key things like property and home ownership were far more difficult given the pricing. I understood early that having the right information at the right time could change someone's trajectory, because I watched people around me struggle without it, and I experienced firsthand what happened when someone finally gave me the tools I needed.

The Moment That Changed Everything

In 2009, New Zealand was in the grip of the global financial crisis. Opportunities were scarce, and for a lot of people it was difficult to see a way forward. That year, I enrolled in Trade and Enterprise New Zealand's "Be Your Own Boss" programme, a free three month course designed to help people develop a viable business case and get started on their own terms. For those who demonstrated a strong enough plan, there was a small financial grant available at the end. I completed the course and was awarded one of the two grants.

I had been tinkering with websites since the early 2000s, but that course gave shape to the idea that I could build something useful at scale. It is a powerful example of how something relatively simple can fundamentally change the trajectory of a person's life when the infrastructure and the societal ladder are there to climb. That investment by Trade and Enterprise New Zealand has been repaid many times over through the taxation contributions I have made to this country in the years since, and through the millions of people the tools I built have gone on to help for free.

My first attempt at client web design taught me something important fast: I did not want to build things for clients. I wanted to build things for people. Clients want their vision built. People just want the truth. I found the truth more interesting.

I noticed that New Zealanders were constantly searching for calculation tools online, and that most of what they found was either outdated, inaccurate, or buried behind advertising that made the experience miserable. So I started building. The first calculator, a GST tool launched in 2011, reached the number one spot on Google within weeks. It was simple, it was fast, and it gave people what they needed without asking for anything in return.

Finding an Edge in a Market Full of Giants

In those early days, I was competing against established companies with significant budgets. I could not outspend them. So I outworked them. I developed a strategy built on patience and precision: targeting narrow gaps that bigger players ignored, acquiring strong domain names that matched exactly what people were searching for, and building tools that worked better than anything else available at the time.

One successful calculator became ten. Ten became fifty. Fifty became over one hundred and fifty individual websites, each solving a specific problem for a specific group of people. At one point, I was ranked among the top ten Google Publishers in New Zealand, not through spending, but through relentless attention to what people actually needed.

Why Free? Because the Motive Matters.

People sometimes ask why everything on this site is free. Sometimes free is low quality, but not always. It depends entirely on the motives of the creator. My motive has never been revenue. It has always been reach.

I chose to keep everything free because the moment you charge, you lose the people who need it most. I have seen what paywalls do to financial education. They turn knowledge into a product instead of a public good, and the people who need it most are the ones locked out. Every tool on this site exists because someone needed it, not because someone paid for it. That is what independent actually means: no bank, no insurer, no product provider tells me what to build or what to recommend.

A prominent New Zealand business figure once reached out about Salary.co.nz, recognising the value of its dataset covering over 200,000 roles. I chose not to sell. If you sell the data, you sell the trust. I was not willing to trade one for the other. That principle has guided every decision. If a project does not serve the people it was made for, it does not ship.

From 150 Sites to One Platform

As the web evolved, managing over one hundred and fifty standalone sites became unsustainable. I saw the opportunity to do something better: bring everything together under one roof.

That vision became Calculate.co.nz. A single, purpose-built platform that transformed scattered resources into a unified experience. Instead of dozens of separate calculators living on separate domains, users could now find everything in one place: mortgages, tax, KiwiSaver, lending, budgeting, investment, and more. All free. All designed for the New Zealand market. All held to a standard where accuracy is not negotiable. One site to bookmark. One place to trust.

Building Tools That Changed Conversations

Along the way, several projects took on a life of their own.

PropertyPrice.co.nz brought property price transparency to the New Zealand market at a time when that information was difficult to access. Over 400,000 people used it because the information had always existed; it had just never been made accessible to ordinary Kiwis.

Salary.co.nz exposed remuneration ranges across more than 200,000 roles, giving job seekers in New Zealand and Australia something they had never had before: a clear picture of what their work was worth.

And if external pressure threatens the integrity of the work, I would rather step back, regroup, and come back stronger than compromise on what matters.

What Drives This Work

I am, by most measures, deeply introverted. I have turned down television and radio opportunities across the years because the spotlight has never been the point. I would rather build something that helps a million people quietly than impress 1,000 people in the public eye.

I have never been able to switch off when I know something could be better. That restlessness is what keeps this platform growing. Nobody sees the 4am debugging sessions or the weekends spent checking every decimal. They see the calculator and it just works. That is how it should be.

I get emails almost every day requesting help and tools. The demand has never stopped. When someone takes the time to email and say thanks, it means more than they realise. The quiet appreciation from people I have never met is the strongest validation this work receives.

At university I completed majors in Human Geography and Social Anthropology, and that academic grounding has shaped everything. It taught me that behind every number is a person with a story, a stress, and a decision to make. Most people think financial confidence comes from earning more money. It does not. It comes from understanding what you already have.

Legacy, Not Revenue

I do not measure success in dollars. I measure it by how many people the site helps each year, and those moments where someone tells me they found it genuinely useful. The moment someone I had never met told me my tool helped them buy their first home, I knew this was no longer a side project. It was a purpose.

Most people who use this site will never know my name. That sits well with me. Building a legacy that transcends just making money is what matters most, and knowing my family can look at what I have done and be proud. I tell my family that I spend my evenings helping people who may need assistance, and that it is important to uplift those who may not be in the same position we are. They understand why it matters.

I believe that innovation does not require a loud entrance. It requires an unconventional mindset and the willingness to keep showing up.

One Thing I Wish I Had Been Told

When I was 18, I wish someone had told me to be a little less frugal, and to spend more on living life as an 18 year old rather than saving for when I was older. Because you can always earn the money back, but you cannot get back the time or the life stage you were in. That perspective informs the way I write the guides on this site: practical, honest, and respectful of the fact that money is not just numbers. It is time. It is choices. It is life.

A Rising Tide Lifts All Boats

My life and career have been shaped by key moments where a person or an organisation created an opportunity for me to grow, adapt, and move forward. Those moments did not happen in isolation. They reflect something broader about how society works.

Coming from a background in Human Geography and Anthropology, that idea carries real weight. We are shaped by the structures we grow up in, but we are not confined by them. Through our own actions and choices, we can create opportunities for others, just as others have done for us. In doing so, we both lift and are lifted, strengthening the society we are all part of.

What You Will Find Here

Calculate.co.nz now houses over 203 free calculators and over 129 financial literacy guides, covering everything from PAYE and GST through to mortgage comparisons, KiwiSaver projections, retirement planning, student loans, and investment analysis. Every tool is designed with two principles: simplicity and accuracy. People trust this site with their biggest financial decisions. That trust is earned through accuracy, every single time, on every single calculator.

The guides are written to be understood by anyone, regardless of financial background. No jargon walls. No assumptions about what you already know. If a teacher uses one of these guides in a classroom, that is the highest compliment this site can receive.

The site is also part of a broader family of resources. In 2023, I launched Realtor.co.nz with what is now a dedicated team. Realtor.co.nz is New Zealand's leading property transaction literacy website. Whether you are buying, selling, or building property in New Zealand, we have your back with a heap of resources and insights built just for you. My own experience building a home in Canterbury fed directly into the platform's Builder Guide, ensuring it contained real, practical, firsthand knowledge rather than generic advice.

The Promise

Everything on this site is free, and it will stay that way. The commitment I made fifteen years ago, that access to clear financial knowledge should never depend on what someone can afford, is the same commitment that guides every new calculator, every new guide, and every update published here today.

I work on Calculate.co.nz from a small village in Canterbury. Good tools do not need a corner office. They need someone who cares enough to keep building. The ambition is not small. But the purpose is simple: help people make better decisions by giving them the tools and information to do so, and never charge them for it.

If Calculate.co.nz has helped you answer a question, plan a decision, or feel a little more confident about your finances, then it is doing exactly what it was built to do.
