I started doing the same as soon as I started working.
Something else that I recommend: Bump this up by 5% every few months and see how it works out. We can often get by with so little (especially people like me who have lived the miserly university life) and we can actually be /happy/ with it, that it just does not make sense to hold back.
I also like the idea of dedicated goals: For e.g. sponsor x children, feed x families etc. This helps solve the problem in manageable chunks and is easier for others to understand. (i.e. if every person helped x other people, we'd get rid of poverty/hunger).
