Am no going to get involved in directly discussing income, is between me and the feudal lords who tell me to which charity I'm required under penalty of prison to "donate".
What I WILL say is, our financial advisor told us years ago that the typical recommendation for a "hobby" is 5% of net income, up to 10% if you include "entertainment" items also in this category. So example if the only "entertainment" you do/have is hobbying, then your number is 10%, but if you not only hobby but also go to Eagles' games, go to the movies, etc, then your hobby ought to be no more than 5%. For me, I collect slash shoot guns, and I monger, so each of these gets around 5%, for a total spend in this category of 10%, some months if I don't buy a gun or don't go to the range as often, that's more for hobbying, and vice versa, if I want to make a big purchase that month, then hobbying gets a little less. Can do with this as you like.
They say it's not what you make, it's what you keep.
