I will bite. L4 Google in Zürich, Switzerland. Base: 163k CHF (very low, just promoted), 15% bonus, 50k USD GOOG / year. Not counting stocks, I net 9k a month while maxing retirement account (aka Roth IRA but with less returns) at 2.7k CHF / month. Rent: 2.3k / month in city center, Health insurance: 350 CHF / month. No other significant expenses.

I invest 3.8k CHF / month from base only. All in all, I save ~100k CHF a year counting bonus and stocks.
