I work from home and my computer is paid by the company and I get a little compensation which covers internet and power etc. So no spending there! But I save a lot by not commuting and eating at home.
In my situation, my computer is paid by the company, but that's it. I drive my kids to and from school which is on the way to the office, so my commute has been extended. My employer also gave us a lunch credit which we lost now that we don't go to the office anymore.
