Up until now, I've been making my donations to charity in a very naive way, by just skimming the top 'x'% off of my raw income and using that bucket for donations.
Recently, I have been making more money, which has prompted me to ask the question, is there a smarter way to do this? Is there some way I could take that same percentage and invest it for an ultimately better payout to the charities I donate to? Some delay is okay up-front if it's needed to get my strategy seeded to start working for me, but the key is that I would utilize some investment that still allows me to make regular payments.
I will provide here one strategy I am considering as a concrete example of the sort of thing I'm trying to accomplish. One thing I have considered but still don't know much about is getting bonds that mature at different times - a month out, 3 months out, 6 months out, 9 months out, and a year out (or some similar plan) so that when I make the donation, I get to donate the percentage I took out of my income plus the interest collected on the bond. Right now, with interest rates as they are, bonds aren't particularly appealing, anyway, but this may be a better strategy at some other time.
What are some other strategies available to me?
