How much money did the founders of Woodstock festival 1969 make?

The founders of the Woodstock festival 1969, Michael Lang, John P Roberts, Joel Rosenman, and Artie Kornfeld, initially invested $1.2 million in the event. After the festival's conclusion, the organizers faced unexpected expenses, including the cleanup cost and a lawsuit with local farmers. As a result, they incurred a substantial financial loss.

Woodstock's financial burden was relieved with the success of the documentary film and soundtrack album. Michael Lang later revealed in an interview that he only started earning a profit from the festival in the 1980s.
