I was filling out electronic paperwork for financial aid last night for my masters program and one of the questions asked for my net worth. Basically, I had to add up all of the value in our savings, checking, cash reserves, and investments (like real estate) and then subtract all of our debts. You can't count the house you live in as an investment in this formula.
Considering that our car, house, student loans, and credit cards add up to a larger amount than our savings and checking accounts, we're worthless. Actually we're less than worthless because the debt on our house is worth more than our entire savings and we don't have any investments. Actually, I think I may still owe more on my car than we have saved, although it's getting close to breaking even on that.
This is good because my plan is to die penniless in a gutter somewhere. That'd be too hard to do if I had net worth to get rid of before then.
