I track my net worth monthly on NetworthIQ.
Our net worth at the end of December 2010 was $644,730. Thats down $3,559 compared to November. That is a change of -0.55% for the month.
We didn't have any major changes in our finances. Our retirement accounts were up for the month. The value of our real estate and my company stock went down. The amount of cash on hand was also down marginally.
