How to calculate Child Care expense in Savings Rate

[Clinical]

Just a quick question, I'm trying to rap my head around this savings rate calculation.  In order for my wife to work, we need to pay for child care.  Her hourly wage, $50/hr for 8 hours a day more than covers the cost of child care ($60/day).  Child care is obviously an expense and I'm guessing it should be added as an expense when calculating savings rate, correct?  But then how should I think about it when it comes to how long it will take to retire... my point being that we won't need the expense of child care once we retire.

Your savings rate and your projected budget in retirement are two separate things.

Your savings rate is not actually very useful. Your projected budget is essential for planning.

A lot of things will change for most people in retirement. Health insurance, commuting costs, travel expenses, for many even housing will change.

Go easy on your head: ignore "savings rate".

Do you have government subsidies? If you do, you need to take them into account in your calculation.
