C+
—Program efficiency40% of the ratingNo expense breakdown in filings
Measures how much of every dollar spent actually reaches programs, plus what it costs to raise $100 of donations. The worse of the two measures sets the letter (85%+ to programs is an A; under $15 to raise $100 is an A), averaged over the three most recent filings. Not scored for Bill & Marian Cook Foundation— this filing type doesn't report it, and the rating simply skips it (never counts it against the organization). See the exact thresholds →
B+Financial health25% of the rating596 mo reserves · +2% margin
