I spent several years working toward the goal of maximizing my Free Time, and hit a point a couple years ago where I'm effectively as Retired as I want to be, at any given moment. The SaaS businesses tick away in the background and seldom require my intervention apart from a quick customer service email sweep every couple days.

I'd recommend this path over the VC + Co-Founders "Startup" life that gets promoted here so often, since I've never seen an outcome from that track that appears to me to be relaxing and enjoyable.

Anyway, regarding the calculator submitted here, it seems to use a bunch of the things I do in (what I consider) my Free Time to deduct from the amount of (what it considers) my Free Time. When I have the chance, I go out Bouldering (which it counts as fitness) or play with my kids if they're off school (which it dings as parenting).

Every hour you're not working for somebody else in exchange for money aught to be considered "you" time. All the other things on that list seem like perfectly fine ways of spending that time.
