This doesn't include the opportunity costs of not being at home. Since you're not at home, you can't tidy up for a few minutes during a break. You can't prepare a meal for dinner that takes a long time. You can't run a quick errand in the middle of the day without eating up "sick" time. You need to provide childcare for kids after school.
If they want me in an office they need a good goddamn reason to do one of the most dangerous things I do all day - driving - and to pay me for all the things I'm missing out on. Not just for the commute, but a cleaning service, child care, and takeout for dinner.
Yeah when I’ve been allowed to work from home I’ve either done chores or talked to my wife during breaks. And I’ve been more comfortable doing the things that make me more effective in my work that bosses don’t like like listening to books during repetitive work
You need to provide childcare for kids after school.
My boss's boss is the type to say you need to have adequate child care even if you're working from home so as to be undisturbed the same as if you were in the office. Luckily I had a migraine when he said it or I would have said something that would have gotten me fired.
It depends on circumstances. We have two children, one is four and a half, the other is 9 months old. My wife and I both work from home (well my wife will be, she's still on maternity leave with our baby). We have to have daycare, we'd personally go nuts otherwise. So I never factor in daycare in my analysis, it's a sunk cost for me, at the moment. But even disregarding that, I worked out what it really cost me in time, wear and tear on my vehicles, additional insurance, fuel, parking, lunch, etc, and I came out to about $40k.
