Brookings says it’s about $310k per child for a family with 2 children, without including daycare or higher ed costs [1]. US median lifetime income is roughly $1.65 million [2]. Daycare averages somewhere between $10k-$15k/year per child [3]. In state public school tuition is ~$100k for 4 years [4]. Median sales price of a house is ~$425k [5]. Total cost of that house with mortgage interest and taxes over 30 years is roughly double that.
