When I donate to Life You Save, the money is divided equally and goes to their 22 highest rated charities. Is this inefficient?
Givewell has something similar. You can donate monthly to Givewell and have them forward the money to several different charities from their list. Is this inefficient?
I am donating $50 automatically each month to each of the 5 organizations. Would it make much of a difference if I just picked one and donated $250/month to it? How much of a difference? How much is the overhead on processing automatic monthly donations?
