PBSScore Breakdown

A
87.9
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
81%

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

Transparency35% weight
100%

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.

Data: FEC, SEC EDGAR, ProPublica 990s, GDELT / NewsAPI, Wikidata

Formula (v2): PBS = 65% x Philanthropy + 35% x Transparency
