Herbert Derp started the first post, and through his original post and a discussion it became a percentage of the poverty level $10,000/$11,490 = 87%.
This sounded like a good idea, and a way a guy with a family of 7 like me could participate. This level was tough, but I did get close, it seemed like a good level for me.
Here are the updated (2014) poverty levels, and I think, even though it looks like I will miss 2014, I will try again in 2015. I have learned a lot from the trying.
1 $11,670
2 15,730
3 19,790
4 23,850
5 27,910
6 31,970
7 36,030
8 40,090
So, for me with a family of 7, $36,030 * 87% = $31,346/yr. or $2,612.18/month. I include everything in this except principle on my house payment and investments.
