Ha.. I started a thread like this a couple of years ago when my net worth was in the +$50k range, felt like a tool for doing so afterwards. I'll play along though, no shame.

1. 28
2. $60k
3. Inheritance? What is that? $0
4. Hard one there since I havent had my house appraised lately. All things considered possibly $45k

Going by your formula I should be worth $168,000.. interesting formula and I'd love to see how many people at my salary are worth that much.
