Joseph Gordon-Levitt is next at $35 million, while Kristen Johnston and French Stewart are tied at $6 million. These are entertainment-site estimates, not verified statements of the actors’ finances.
How the cast ranks by published estimate
The figures below come from MarkMeets’ cast wealth ranking, whose publication date is approximately 2024. The ordering reflects that outlet’s estimates, not an independently verified measure of anyone’s assets or debts.

What the estimates do—and do not—tell you
Celebrity Net Worth independently repeats the $50 million estimate for Lithgow, and its pages for Johnston and Stewart each give $6 million. The figures for Gordon-Levitt, Curtin and Knight in this comparison come from MarkMeets; a Jane Curtin page is available at Celebrity Net Worth, but the consulted excerpt did not expose a net-worth figure.
Neither publisher supplies audited financial disclosures for these performers or a robust account of how assets and liabilities were calculated. The rankings are therefore useful as a snapshot of published estimates, not as proof that one performer’s actual wealth exceeds another’s. In particular, the $2 million difference between the two middle estimates should not be treated as meaningful precision.

Who is included in this ranking?
This six-person comparison follows the scope of the MarkMeets list. It includes the five actors who starred throughout the series—Lithgow, Johnston, Stewart, Gordon-Levitt and Curtin—plus Wayne Knight, who recurred earlier and appeared in seasons 3–6. The Television Academy’s series reference also lists recurring cast members Simbi Khali and Elmarie Wendel, among others; this is not a complete ranking of everyone who appeared on the show.
