Sums & Tax

Money should
make more sense

Having spent over 10 years working in financial services, I've realised one thing: money isn't always as straightforward as it should be.

The rules are there, but understanding what they actually mean for you is another matter.

Sums & Tax tools are designed to make the numbers easier to understand. They show you the calculations, how different scenarios work and what the figures mean.

Why I built these

I kept seeing the same thing. The numbers can be worked out, but for most people they still don't add up, because nobody shows them the working.

A pay rise that’s worth less than it looks. Rent that isn't the same as profit. A monthly budget that never quite matches the month you actually had.

So I built tools that do the sums on your own figures and show you the working. They don't tell you what to do. They let you see it, so the decision is yours.
