Wife and I both started at 22 in corporate jobs, making $40K each/year. Basically have worked straight through, with escalating comp based on performance/progress. Today, we have $3.15M in the bank, and gross about $750K/year + investments (which can range from big negative, e.g. 2008, to big positive, e.g. 2009 or 2012).
At our current run rate, I push for $400K of annual post-tax savings, + investment returns. We are very non-materialistic – e.g. we live in a $430K house and drive 1998 and 2001 cars, with 143K and 65K miles, respectively – but similar to others on the thread, have traveled widely (e.g. $25K trip over 5 weeks to Australia/NZ last summer), and we do pay amply for our 2 kids’ nannying/activities.
