Score Breakdown
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.
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
No giving data on file. That is a gap in our sources, not a finding that this person gives nothing — and because the component still counts as zero, it holds this score down. Know of a gift we are missing? Tell us and we will source it.
How much sourced, public accountability data exists — net worth, political contributions, SEC filings, foundation 990s, news coverage, and a verified profile. More public disclosure scores higher.
