My childcare cost is $52k/year for two kids. To hire a private nanny for TWO kids, it'll be at least $35/hour with benefits (insurance, paid time off etc) in my area. That'll be around $80k/year for a private nanny. And once the kids are older, the value of a nanny isn't as good IMO since they don't provide the variety of social challenges that a daycare can provide (group working, relationship building, conflict resolution etc...). We have friends with kids of the same age that don't go to day care and have nannies instead, and the differences in social interaction are significant - maybe we just get lucky but I think our kids build a lot of skills being in a bigger group.
