Billy Davis Jr.'s net worth is estimated at around $5 million to $8 million, built from his role as a founding member of The 5th Dimension, decades of Grammy-winning recording and touring income with wife Marilyn McCoo, and their 1977 CBS television series. Some outlets cite a combined household figure of roughly $8 million for the couple; a 1987 Los Angeles-area home the pair bought for $950,000 sold in December 2024 for $4.65 million, which is consistent with a multimillion-dollar estate built up over a long joint career. His exact personal assets and royalty income are not public, so this range is a realistic estimate rather than a filing-based figure.

Early Life
Billy Davis Jr. was born June 26, 1938, in St. Louis, Missouri. He moved to Los Angeles as a young man, where he became involved in the local vocal-group scene that would eventually produce The 5th Dimension.
Founding The 5th Dimension
Davis was a founding member of The 5th Dimension, formed in 1966 out of an earlier group called The Versatiles, alongside Marilyn McCoo, Florence LaRue, Lamonte McLemore, and Ronald Townson. The group's breakthrough came with 1967's "Up, Up and Away," written by Jimmy Webb, which won four Grammy Awards in 1968. Their biggest hit followed in 1969: the "Aquarius/Let the Sunshine In" medley from the musical "Hair" reached number one on the Billboard Hot 100 and won the Grammy for Record of the Year. The group also charted with "Wedding Bell Blues" and other hits through the late 1960s and early 1970s before Davis and McCoo left in 1975 to build a duo act.
Marriage to Marilyn McCoo and Duo Career
Davis married fellow 5th Dimension member Marilyn McCoo on July 26, 1969, while both were still with the group. After leaving The 5th Dimension in 1975, the couple recorded as a duo, scoring a number-one hit in January 1977 with "You Don't Have to Be a Star (To Be in My Show)," which won a Grammy for Best R&B Performance by a Duo or Group with Vocals. That same year, they hosted "The Marilyn McCoo & Billy Davis Jr. Show" on CBS, becoming the first African American married couple to host a network television series. Davis was diagnosed with prostate cancer in 1999.
