So, I was chatting with my husband this morning about why some parents stay at home. From what I have read online sometimes one parent's paycheck would be completely eaten up by child care expenses, so forgoing a paycheck and staying home with one's own child makes sense.

My husband says this still doesn't make financial sense because now that once working parent loses benefits that impact retirement- Social Security, 401 (k) and pensions. In our home we automatically contribute to our 401 (k) and our employers match a percentage of our contrubution. So, whenever we set up budgets we already exclude our retirement contributions because we don't "take that home." I can see why he includes employee retiremennt contributions as an opportunity cost.

Help me out with the financial opportunity costs of staying at home? Is making the same salary pre-SAH realistic if you plan to re-enter the workforce?
