My first step was setting up regular donations on my oldest credit card and then setting that credit card to autopay as a way to keep it open long term without actually doing anything with it. I think I did $35/month (10 to Planned Parenthood, 10 to local NPR affiliate, 15 to another place) because that was the minimum for autopay.
Last year I started doing $20-$25/month as a donation/mental sanity thing each month. By having it already allocated mentally, when something in the news was taking over my brain I had a sort of pressure release-valve.
Referring to my tracking sheet - Migrant crisis at the boarder? Donate to a news org that was covering it well. Notre Dame burned down and rich people won’t shut up about it? Donate to a Go Fund Me for some black churches that were burned down by a racist arsonist. Hurricane Dorian? Donate to a larger, well-reviewed organization helping the Bahamas. Nothing really crazy going on? Local food bank, family homeless shelter, school supply drive, etc.
I did allocate half of my stimulus money to charity (increased monthly PP and NPR donations for the rest of the year along with some one-time donations) and part to local businesses specifically, and half to myself for fun stuff I wouldn’t have spent money on anyway. I’m currently tracking this in a spreadsheet so I can keep track of what happens when, since we already had one round of state-mandated business closures and who knows when I’ll be back in the office or feel comfortable getting a massage again.
I like the idea of increasing charitable contributions after a raise. I had done +1% to my 401k with a raise, it makes sense to do something similar with charity.
