Thanks for posting this, it's incredibly informative and interesting. If you look at "Scenario 1: Professional Wife and Slacker Husband" in the California section, you'll see a situation very similar to the one I am in, just that the dollar amounts involved are lower, (I earn around $125K, invested about $10K into ex-wife's part time business), the child were both from one parent, and the genders are swapped. In my case the monthly combined spousal and child support that Dissomaster spit out was $3,300.
