How much of your monthly income does every put back into their business?

Having been doing some basic accounts stuff today i came to the realisation that we do put a fair amount of what we make each month back into the business.

Domains, Hosting, Content, Designs, Etc all add up on a monthly basis and to be honest, until earlier today i didnt realize just how much of the companies profits actually went back into the business.

Not that thats a bad thing though because i also came to the realization that each time we put money in, we usually end up with more profits :thumbsup:

So how do you plan how much additional money you will put back into your business each month?
