GEOList Summary: Indirect Rate

I am seeking guidance on a more equitable policy for Indirect. I am noticing that more and more nonprofits are adding an indirect rate to their grant budgets. It used to be that we only saw this with universities and research entities. When talking to some of our grantees about this rate, I've learned they each calculate the rate differently. Also, when an applicant breaks down what would normally be considered "indirect," we don't add up the expenses to see if they come within our policy. Our current policy is no more than 12% (but again, that's if they title it "indirect.") Please include your average grant size or grant range in your response.
