Show HN: Calculator for freelancers to figure out how much something will cost

Hi!

This is a mini-calculator for you if you are a freelancers or self-employed and can offset business related expenses from your taxes.

The basic question it aims to answer is: "How much less money can I pay myself in salary at the end of this month if I buy this particular thing", or asked in a different way: "What is this thing actually going to cost me"?

The calculation is incredibly simple, but I have recreated it in excel sheets often enough that I thought I'd be worth putting it online for myself and others to use.

Happy calculating!
