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.
