<prompt> Human: I currently spend 237; of my income on charity monthly fixed-sum payments to a charity organization I trust and respect. This expense is entirely voluntary and not related to any specific emotional commitments or past experiences, i.e. I just do it because I feel that I should. Im happy with this amount but Im wondering if there is a justified benchmark ceiling on such non-mandatory expenses.  <response>: If youre otherwise fiscally balanced, doing for others is healthy on many levels. If youre comfortable with the amount, that should be enough. If you feel like you can do more without upsetting other balance, do more.If youre looking to compare, we also do a couple percentage points. Were not altruistic, because its mostly to offset tax liability . We also do it to feel better about having extra when others dont; because I think if youre balanced and have extra, then you probably should give something back.Theres no prescription, except if youre unbalanced probably less, or youre seeking max tax benefit probably more. The rest is spiritual and how much you believe in the cause or societal impact you may be making...which is still kind of spiritual.
