I can't throw out a fixed number if you're asking for yourself as everyone's number will vary greatly depending on their existing cost of living (debt, loans, children, location, etc etc etc...). I won't answer in my personal context either. However, as a general rule of thumb, if you have 12 months runway base on your current cost of living AND you make enough to cover your current monthly run rate, and your projects are potentially growing or you want to free up time for working on other things or things in general, that would be a good rule of thumb.
