Who am I?

My name is Ben Colgate, I'm a UX/UI Designer.

Why build it?

I built my first take home pay calculator (using Flash) prior to my first full-time job. I wanted a simple way to calculate what my pay was going to be. When I was going to receive my first pay rise, I wanted to know the percentage increase it would be after tax. When a lot of Kiwis were flocking to Australia I wanted to see what I could be earning across the ditch. When two political parties were promising tax cuts leading into an election, I wanted to see what they were bribing me with.

So ultimately I built it for my own interests, but I'm happy to share it with the world.
