I realize that some financial context might be required for such a question, so here goes.
30/m/married, just had first child 1 month ago (he's a cute little guy)
Combined income: $175k (this will drop in 2 months to $145k, as my wife is dropping to 60% as part of an intricate plan to have 0 childcare expenses)
Monthly Expenses
Mortgage: 30yr loan @ 4.75%, currently at about $285k on a house worth about $400k - $1550 + $400(private parental loan, hardly any interest, to be paid off in 5 years)
Property Taxes: ~ $275
Utilities: ~$150
Car Loans: None
Insurance: Not totally sure on this number. Paying for 2 cars + house. Redid the insurance 6 months ago.
Student Loans: I've been aggressively hitting these for so long, I have no idea what the minimum is. They will be paid off in 4 months, and I've been hitting them with $1200/mo.
Gas: $150 (it's already been less with my wife at home)
Food: $600 (typically it is this much, but having the wee one at home has successfully reduced "eating out" to zero. I'd say it's around $450 now)
Cable: Cutting the cord next month
Internet: TBD, depending on how I haggle when cutting the cord
Home Phone: Free - I set up a sweet Obi110 with Google Voice. Free calls from a normal phone. Seemless.
Cell Phones: $100 - One of our main tech vices. At least I get 25% off through work.
Investments
Combined 401k balance: $140k
Combined IRA Balance: $70k
Emergency Fund (some in cash, some in balanced mutual funds): $35k
As I said, we fully fund our IRA now, and contribute to our 401k up to our employer match.
Not sure if this helps with the original question. I just hope to maximize our potential for ER in the future.
