Don't mean to kick up a dead thread, but I just went through the last two years of bank and mortgage statements, and it looks like our number this year is $194,561.105$194,561.05.
That's a function of savings (pre and post tax), market returns, mortgage principle, house appreciation (tracking Zillow estimates over the course of the year to calculate the delta), and company stock vesting.
In 2011 our network decreased slightly (bad stock picking, family expenses, decreasing home value).
It will be hard to duplicate this again this year, but I think we can get pretty close. $130k went into the 'stache this year, which would be awesome to do two years in a row.
