PBSScore Breakdown

B
50.3
Public Benefit Score

The PBS is a weighted average of 2 components. The formula is open and versioned — the weight percentages below show how much each component contributes to the final score.

Philanthropy65% weight
37%

Evidenced charitable giving — built on what they actually give each year, not parked assets. Dominated by generosity (annual giving relative to net worth — the share of your fortune you give), plus the absolute scale of that giving, plus a small nudge for signing the Giving Pledge (a commitment, not a realized action).

Data: ProPublica 990 charitable disbursements, net worth, The Giving Pledge registry
