Our pretax household income has been about $300K, although it'll be lower this year because DW and I both went part-time in July.
Our spending is around $5000-$6000 a month. That doesn't include income taxes, I don't count that as spending, but it does include property taxes. No mortgage, it was paid off earlier this year.
Some of our major spending categories are:
* property taxes, condo maintenance and utilities (about $800 a month all told)
* charity ($600-$800 a month, some of which comes from a donor-advised fund we're building up)
* groceries ($500-600 a month, two adults and a toddler)
* commuting ($300 a month on train passes and commuter lot parking)
* dining out ($300-400 a month on average)
* travel & vacations (we've had a few weekend getaways this year and are planning one or two more, another $400 on average)
Daycare would have been on that list a few months ago, but we're doing our own childcare now that we're both working part-time. Other, smaller categories are home and personal care needs, car insurance, cell phone and internet, gym membership, medical copays, clothing, books, coffee, booze...
I don't think we live an extravagant life. Some of this is just the realities of living in an HCOL area, and we save a lot more than we spend. But I admit $6000 a month is higher than I'd like, and I'm trying to find ways to reduce it before we RE, especially because we'll have to pay for our own health insurance once we're no longer employed.
Obviously we won't have commuting expenses after retirement, and travel, charitable donations and restaurants we could reduce at will. Other things we could optimize are cable TV (going to cut the cord when our promo rate runs out, Netflix/Amazon Prime is basically all we watch), wireless service/phones (should probably switch to an MVNO), gym membership (should cancel and work out at home), coffee shops (facepunch!)... Really, we just have to be more vigilant about not letting little things slip through the net. None is excessive by itself, but together they add up.
