In 2008, the John D. and Catherine T. MacArthur Foundation paid out $252.3 million in grants and program-related investments to organizations and individuals in the United States and around the world. Actual cash paid out varies from year to year depending on payment schedules of larger grants.

Total dollars paid in 2008: $252,254,918

MacArthur's charitable administrative expenses totaled $32.3 million in 2008, about 11.2 percent of total charitable expenditures.

To focus its grantmaking and increase its impact, MacArthur has reduced the number of grants while increasing the size of the average grant. In 2008, the Foundation authorized 571 grants to organizations. The average size of grants was $553,000.

*The increase in the average grant size in 2007 is due in large part to a small number of especially large grant authorizations during 2007. Ten large approvals in 2007 accounted for nearly one-third of the total $327 million authorized.
