Real talk: How much do you actually earn after factoring in childcare?

I make $75k gross. After taxes ($15k), my wife's full-time daycare costs ($21k), and commuting/lunch out ($4k), my actual take-home is... basically nothing. So technically I work full-time to break even. Which sounds bonkers when I type it out. Wife thinks I should stay home but we'd lose my benefits. How are other people thinking about this math?
